Frequently Asked Questions and Information Thread

This FAQ and information thread serves to inform both new and existing users about common Bitcoin topics that readers coming to this Bitcoin subreddit may have. This is a living and breathing document, which will change over time. If you have suggestions on how to change it, please comment below or message the mods.
What is /btc?
The /btc reddit community was originally created as a community to discuss bitcoin. It quickly gained momentum in August 2015 when the bitcoin block size debate heightened. On the legacy /bitcoin subreddit it was discovered that moderators were heavily censoring discussions that were not inline with their own opinions.
Once realized, the subreddit subscribers began to openly question the censorship which led to thousands of redditors being banned from the /bitcoin subreddit. A large number of redditors switched to other subreddits such as /bitcoin_uncensored and /btc. For a run-down on the history of censorship, please read A (brief and incomplete) history of censorship in /bitcoin by John Blocke and /Bitcoin Censorship, Revisted by John Blocke. As yet another example, /bitcoin censored 5,683 posts and comments just in the month of September 2017 alone. This shows the sheer magnitude of censorship that is happening, which continues to this day. Read a synopsis of /bitcoin to get the full story and a complete understanding of why people are so upset with /bitcoin's censorship. Further reading can be found here and here with a giant collection of information regarding these topics.
Why is censorship bad for Bitcoin?
As demonstrated above, censorship has become prevalent in almost all of the major Bitcoin communication channels. The impacts of censorship in Bitcoin are very real. "Censorship can really hinder a society if it is bad enough. Because media is such a large part of people’s lives today and it is the source of basically all information, if the information is not being given in full or truthfully then the society is left uneducated [...] Censorship is probably the number one way to lower people’s right to freedom of speech." By censoring certain topics and specific words, people in these Bitcoin communication channels are literally being brain washed into thinking a certain way, molding the reader in a way that they desire; this has a lasting impact especially on users who are new to Bitcoin. Censoring in Bitcoin is the direct opposite of what the spirit of Bitcoin is, and should be condemned anytime it occurs. Also, it's important to think critically and independently, and have an open mind.
Why do some groups attempt to discredit /btc?
This subreddit has become a place to discuss everything Bitcoin-related and even other cryptocurrencies at times when the topics are relevant to the overall ecosystem. Since this subreddit is one of the few places on Reddit where users will not be censored for their opinions and people are allowed to speak freely, truth is often said here without the fear of reprisal from moderators in the form of bans and censorship. Because of this freedom, people and groups who don't want you to hear the truth with do almost anything they can to try to stop you from speaking the truth and try to manipulate readers here. You can see many cited examples of cases where special interest groups have gone out of their way to attack this subreddit and attempt to disrupt and discredit it. See the examples here.
What is the goal of /btc?
This subreddit is a diverse community dedicated to the success of bitcoin. /btc honors the spirit and nature of Bitcoin being a place for open and free discussion about Bitcoin without the interference of moderators. Subscribers at anytime can look at and review the public moderator logs. This subreddit does have rules as mandated by reddit that we must follow plus a couple of rules of our own. Make sure to read the /btc wiki for more information and resources about this subreddit which includes information such as the benefits of Bitcoin, how to get started with Bitcoin, and more.
What is Bitcoin?
Bitcoin is a digital currency, also called a virtual currency, which can be transacted for a low-cost nearly instantly from anywhere in the world. Bitcoin also powers the blockchain, which is a public immutable and decentralized global ledger. Unlike traditional currencies such as dollars, bitcoins are issued and managed without the need for any central authority whatsoever. There is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank. Read the Bitcoin whitepaper to further understand the schematics of how Bitcoin works.
What is Bitcoin Cash?
Bitcoin Cash (ticker symbol: BCH) is an updated version of Bitcoin which solves the scaling problems that have been plaguing Bitcoin Core (ticker symbol: BTC) for years. Bitcoin (BCH) is just a continuation of the Bitcoin project that allows for bigger blocks which will give way to more growth and adoption. You can read more about Bitcoin on BitcoinCash.org or read What is Bitcoin Cash for additional details.
How do I buy Bitcoin?
You can buy Bitcoin on an exchange or with a brokerage. If you're looking to buy, you can buy Bitcoin with your credit card to get started quickly and safely. There are several others places to buy Bitcoin too; please check the sidebar under brokers, exchanges, and trading for other go-to service providers to begin buying and trading Bitcoin. Make sure to do your homework first before choosing an exchange to ensure you are choosing the right one for you.
How do I store my Bitcoin securely?
After the initial step of buying your first Bitcoin, you will need a Bitcoin wallet to secure your Bitcoin. Knowing which Bitcoin wallet to choose is the second most important step in becoming a Bitcoin user. Since you are investing funds into Bitcoin, choosing the right Bitcoin wallet for you is a critical step that shouldn’t be taken lightly. Use this guide to help you choose the right wallet for you. Check the sidebar under Bitcoin wallets to get started and find a wallet that you can store your Bitcoin in.
Why is my transaction taking so long to process?
Bitcoin transactions typically confirm in ~10 minutes. A confirmation means that the Bitcoin transaction has been verified by the network through the process known as mining. Once a transaction is confirmed, it cannot be reversed or double spent. Transactions are included in blocks.
If you have sent out a Bitcoin transaction and it’s delayed, chances are the transaction fee you used wasn’t enough to out-compete others causing it to be backlogged. The transaction won’t confirm until it clears the backlog. This typically occurs when using the Bitcoin Core (BTC) blockchain due to poor central planning.
If you are using Bitcoin (BCH), you shouldn't encounter these problems as the block limits have been raised to accommodate a massive amount of volume freeing up space and lowering transaction costs.
Why does my transaction cost so much, I thought Bitcoin was supposed to be cheap?
As described above, transaction fees have spiked on the Bitcoin Core (BTC) blockchain mainly due to a limit on transaction space. This has created what is called a fee market, which has primarily been a premature artificially induced price increase on transaction fees due to the limited amount of block space available (supply vs. demand). The original plan was for fees to help secure the network when the block reward decreased and eventually stopped, but the plan was not to reach that point until some time in the future, around the year 2140. This original plan was restored with Bitcoin (BCH) where fees are typically less than a single penny per transaction.
What is the block size limit?
The original Bitcoin client didn’t have a block size cap, however was limited to 32MB due to the Bitcoin protocol message size constraint. However, in July 2010 Bitcoin’s creator Satoshi Nakamoto introduced a temporary 1MB limit as an anti-DDoS measure. The temporary measure from Satoshi Nakamoto was made clear three months later when Satoshi said the block size limit can be increased again by phasing it in when it’s needed (when the demand arises). When introducing Bitcoin on the cryptography mailing list in 2008, Satoshi said that scaling to Visa levels “would probably not seem like a big deal.”
What is the block size debate all about anyways?
The block size debate boils down to different sets of users who are trying to come to consensus on the best way to scale Bitcoin for growth and success. Scaling Bitcoin has actually been a topic of discussion since Bitcoin was first released in 2008; for example you can read how Satoshi Nakamoto was asked about scaling here and how he thought at the time it would be addressed. Fortunately Bitcoin has seen tremendous growth and by the year 2013, scaling Bitcoin had became a hot topic. For a run down on the history of scaling and how we got to where we are today, see the Block size limit debate history lesson post.
What is a hard fork?
A hard fork is when a block is broadcast under a new and different set of protocol rules which is accepted by nodes that have upgraded to support the new protocol. In this case, Bitcoin diverges from a single blockchain to two separate blockchains (a majority chain and a minority chain).
What is a soft fork?
A soft fork is when a block is broadcast under a new and different set of protocol rules, but the difference is that nodes don’t realize the rules have changed, and continue to accept blocks created by the newer nodes. Some argue that soft forks are bad because they trick old-unupdated nodes into believing transactions are valid, when they may not actually be valid. This can also be defined as coercion, as explained by Vitalik Buterin.
Doesn't it hurt decentralization if we increase the block size?
Some argue that by lifting the limit on transaction space, that the cost of validating transactions on individual nodes will increase to the point where people will not be able to run nodes individually, giving way to centralization. This is a false dilemma because at this time there is no proven metric to quantify decentralization; although it has been shown that the current level of decentralization will remain with or without a block size increase. It's a logical fallacy to believe that decentralization only exists when you have people all over the world running full nodes. The reality is that only people with the income to sustain running a full node (even at 1MB) will be doing it. So whether it's 1MB, 2MB, or 32MB, the costs of doing business is negligible for the people who can already do it. If the block size limit is removed, this will also allow for more users worldwide to use and transact introducing the likelihood of having more individual node operators. Decentralization is not a metric, it's a tool or direction. This is a good video describing the direction of how decentralization should look.
Additionally, the effects of increasing the block capacity beyond 1MB has been studied with results showing that up to 4MB is safe and will not hurt decentralization (Cornell paper, PDF). Other papers also show that no block size limit is safe (Peter Rizun, PDF). Lastly, through an informal survey among all top Bitcoin miners, many agreed that a block size increase between 2-4MB is acceptable.

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.
Bitcoin:
The very first, and the highest ever valued, mass-market open source and decentralized cryptocurrency and digital payment system that runs on a worldwide peer to peer network. It operates independently of any centralized authorities
Bitconnect:
One of the biggest scams in the crypto world. it was made popular in the meme world by screaming idiot Carlos Matos, who infamously proclaimed," hey hey heeeey” and “what's a what's a what's up wasssssssssuuuuuuuuuuuuup, BitConneeeeeeeeeeeeeeeeeeeeeeeect!”. He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.
Bull market:
A market that Cryptos are going up.
Consensus:
An agreement among blockchain participants on the validity of data. Consensus is reached when the majority of nodes on the network verify that the transaction is 100% valid.
Crypto bubble:
The instability of cryptocurrencies in terms of price value
Cryptocurrency:
A type of digital currency, secured by strong computer code (cryptography), that operates independently of any middlemen or central authoritie
Cryptography:
The art of converting sensitive data into a format unreadable for unauthorized users, which when decoded would result in a meaningful statement.
Cryptojacking:
The use of someone else’s device and profiting from its computational power to mine cryptocurrency without their knowledge and consent.
Crypto-Valhalla:
When HODLers(holders) eventually cash out they go to a place called crypto-Valhalla. The strong will be separated from the weak and the strong will then be given lambos.
DAO:
Decentralized Autonomous Organizations. It defines A blockchain technology inspired organization or corporation that exists and operates without human intervention.
Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.
Digital Signature:
An encrypted digital code attached to an electronic document to prove that the sender is who they say they are and confirm that a transaction is valid and should be accepted by the network.
Double Spending:
An attack on the blockchain where a malicious user manipulates the network by sending digital money to two different recipients at exactly the same time.
DYOR:
Means do your own research.
Encryption:
Converting data into code to protect it from unauthorized access, so that only the intended recipient(s) can decode it.
Eskrow:
the practice of having a third party act as an intermediary in a transaction. This third party holds the funds on and sends them off when the transaction is completed.
Ethereum:
Ethereum is an open source, public, blockchain-based platform that runs smart contracts and allows you to build dapps on it. Ethereum is fueled by the cryptocurrency Ether.
Exchange:

Fiat money:
Fiat currency is legal tender whose value is backed by the government that issued it, such as the US dollar or UK pound.
Fork:
A split in the blockchain, resulting in two separate branches, an original and a new alternate version of the cryptocurrency. As a single blockchain forks into two, they will both run simultaneously on different parts of the network. For example, Bitcoin Cash is a Bitcoin fork.
FOMO:
Fear of missing out.
Frictionless:
A system is frictionless when there are zero transaction costs or trading retraints.
FUD:
Fear, Uncertainty and Doubt regarding the crypto market.
Gas:
A fee paid to run transactions, dapps and smart contracts on Ethereum.
Halving:
A 50% decrease in block reward after the mining of a pre-specified number of blocks. Every 4 years, the “reward” for successfully mining a block of bitcoin is reduced by half. This is referred to as “Halving”.
Hardware wallet:
Physical wallet devices that can securely store cryptocurrency maximally. Some examples are Ledger Nano S**,** Digital Bitbox and more**.**
Hash:

Pre mining:
The mining of a cryptocurrency by its developers before it is released to the public.
Proof of stake (POS):
A consensus distribution algorithm which essentially rewards you based upon the amount of the coin that you own. In other words, more investment in the coin will leads to more gain when you mine with this protocol In Proof of Stake, the resource held by the “miner” is their stake in the currency.
PROOF OF WORK (POW) :

To you older hodlers out there, How do you feel about bitcoin now?

Not sure if this is how all hodlers end up feeling but i feel something about this run up and how 2020 has played out has really changed how i view bitcoin.
When i started messing around with it in 2015 buying stuff online and mining on my gaming pc it was just a cool idea and some cool way to transact with people globally, i kinda viewed it like runescrape gold but without the runescape part. Still appreciated its potential as a digital gold and global currency but was still like yeah, you can dream.. Didn't think it would actually achieve more than a dream back then.
Now feels different, im glad i decided to hold onto at least a bit of my coin. Ive had way more before, but looking back i can't imagine any way i could have convinced myself holding more, things were different back then, bitcoin was a speculative dream in a lot of ways.
Seeing the stimulus we have had this year and the level of economic destruction that has occurred in my country let alone the rest of the world im seeing bitcoin as a way out of the system. We're seeing it failing in front of our eyes, can't not see it anymore. Its all around us, some people might be still happy with their 100k jobs but people around them are falling down. I just don't see how USD is going to maintain power or lots of other currencies for that matter, maybe Chinese yuan might not fall as much but bitcoin is yours and dollars are promise of someone's future labor (thanks fed for a debt backed currency..). What happens when people aren't able to pay dollars to anyone? The system fails.
Now im not saying bitcoin wont go up forever or down from here. Expect it to go down and dont get worried. Expect USD will strengthen as people scramble to get dollars together at all costs to pay their obligations. USD is deflationary right now even with so much stimulus. Expect a fed coin or something in the next few years, expect them to try regulate bitcoin and get rid of it. This is a big risk im not sure if people understand it as the threat it is. If bitcoin was banned outright with jail time (big motive is govs wanting control of their own taxes, own rates, bonds etc..), assuming the courts still work there will be no legal institutional investment and use cases. This would kill lots of potential future capital and growth, putting bitcoin outside the law, much what it was like in the early days.
Not saying thats going to happen its just a different risk to what was before. Years ago it was a speculation risk, that it was a bubble, that it was worthless. To be fair it was a bubble, it didn't do "much" for a 100b market cap. Today bitcoin is gaining serious, undeniable growth, real use case, real safety and as an inflationary hedge. It always was seen as being a good inflation hedge but i think we are seeing that crystalize today and only more so in the future.
Is this the similar thinking to you older hodlers out there? Did you stop worrying about price fluctuations because you know things were always going to be a hard way up and to almost expect it to fail, but to always end up knowing that the almost cultural backing and common ideas behind bitcoin would never die and as time goes on you only believe in it more?

Minimum Viable Issuance - Why Ethereum’s lack of a hard cap on ETH issuance is a good thing.

This post will explain how the argument used by the average Bitcoin maximalist, thinking that they have found Ethereum’s achilles heel when talking about issuance is actually highlighting one of Ethereum’s strong points and one of the main threats to the longevity of the Bitcoin network.
So first let’s answer the question which I know many people have about Ethereum:

What is Ethereum’s ETH issuance schedule?

Ethereum has an issuance policy of Minimum Viable Issuance. So what does this mean exactly? It means that the issuance of ETH will be as low as possible while also maintaining a sufficient budget to pay miners (and soon to be stakers) to keep the network secure. For example, if ETH issuance was halved, miners would drop off the network and stop mining as it is no longer profitable for them to mine. As a result, the network would be less secure as it would cost less money for an attacker to control 51% of the hash power and attack the network. This means that the Ethereum community plans to change ETH issuance as time goes on to maintain a reasonable security budget which will keep the network secure but will also keep inflation in check. We have done this twice in the past with EIP-649 and EIP-1234 which reduced block rewards from 5 ETH per block to 3 ETH and from 3 ETH to 2 ETH respectively. I previously made a graph of ETH issuance over time here: https://redd.it/it8ce7
So while Ethereum doesn’t have a strictly defined issuance schedule, the community will reject any proposals which either put the security of the network at risk such as the recent EIP-2878, or we will reject proposals which will lead to excessive network security and therefore an unnecessarily high inflation rate (or we will accept proposals which reduce issuance after price rises and therefore the security budget rises). This means that when Bitcoiners accuse the Ethereum Foundation of being no better than a central bank because they can “print more Ether”, this is completely untrue. Any proposals made by the EF which would increase issuance unnecessarily would be rejected by the community in the same way that a proposal to increase the supply of Bitcoin from 21 million to 22 million would be rejected. There is a social contract around both Bitcoin’s and Ethereum’s issuance schedules. Any networks or proposals which break the social contracts of 21 million Bitcoins and minimal viable issuance of Ether would be a breach of these contracts and the new proposed network would be labeled by the community as illegitimate and the original network would live on.

So why is minimum viable issuance better than a hard cap?

Minimum viable issuance is better than a hard cap because it puts the most important part of the network first - the security. MVI ensures that the Ethereum network will always have a security budget which keeps the cost of a 51% attack impractically high. Bitcoin on the other hand, halves its security budget every 4 years until eventually only the transaction fees pay for network security. This means that every 4 years, the amount of money paying for network security halves until eventually, the value of attacking the network becomes greater than the security budget and someone performs a 51% attack (technically the security budget only halves if terms of BTC not in dollars. However, even if the price of Bitcoin more than doubles in the time that the security budget halves, the ratio of security budget to value secured on the network still halves, doubling the financial viability of performing a network attack). The strategy to pay for the security budget once Bitcoin issuance stops is for transaction fees to secure the network since transaction fees are paid to miners. Not only does this have its own security problems which I won’t detail here, but unless Bitcoin scales on layer 1 (layer 2 scaling solutions have their own security mechanisms separate from L1), then fees would have to cost well in the thousands of dollars to secure a trillion dollar market cap Bitcoin that is secured by nothing but fees. If Bitcoin maximalists want a 10 trillion or 100 trillion dollar market cap then expect fees to go up another 10 or 100 times from there.
Ethereum on the other hand, will be able to keep its network secure with approximately 1-2% annual issuance being paid to stakers under ETH 2.0. This is because not all of the network will be staking, so if 33 million of the approximately 110 million Ether in existence stakes under ETH 2.0, then paying this 33 million Ether 6% a year (a very decent yield!) would cost just under 2 million ETH per year which would equate to less than 2% annual ETH inflation. This is also before considering EIP-1559 which will burn a portion of transaction fees which will counter the effect of this inflation and potentially even make ETH deflationary if the sum of all burned transaction fees are greater than the annual inflation. Also, under ETH 2.0, an attacker performing a 51% attack would get his funds slashed (they would lose their funds) if they attack the network, meaning that they can only perform a 51% attack once. However, in Bitcoin, anyone who controls 51% of the mining hash power could perform multiple 51% attacks without losing everything like they could in ETH 2.0.
So in conclusion, while Ethereum doesn’t have the guaranteed anti-inflation security of a hard cap, it does have the guarantee of always paying it’s miners (or stakers under ETH 2.0) enough to keep the network secure. In contrast, while Bitcoin’s social contract may guarantee a hard cap of 21 million, it cannot simultaneously guarantee network security in the long run. Eventually, its users will have to decide if they want a secure network with more than 21 million coins or a tax to pay for security or an insecure network with super high fees and a hard cap of 21 million Bitcoin.
Disclaimer: The details I covered around 51% attacks and network security are simplified. I am not an expert in this field and things are a lot more nuanced than I laid out in my simplifications above.

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Comparing Nano's Nakamoto Coefficient

Inspired by the discussion on the cc subreddit (which I won't link to), I have some questions.
These Nakamoto coefficients aren't very comparable. Miners can reassign their hashrate at any time. Hashrate also has an ongoing, real expense. Nano votes can't be reassigned if the network is controlled, and there's no out of band "real" cost to acquire or maintain control. Thus, it's extremely misleading to try and compare these.
I would say that indeed hashrate has an ongoing, real expense so indeed, performing a 51% attack on Bitcoin will cost you on a per hour basis. On the other hand, get a 51% majority of Nano and you essentially block the network for eternity from what I understand. Bitcoin would most likely also collapse in value if a 51% attack was successfully performed, because even if it were to go offline for an hour and just a few doublespends were performed, it would undermine the store of value mantra quite strongly.
Some sides notes here are, of course, that getting a 51% majority delegates for Nano is extremely difficult or expensive, as you need to buy up a large percentage of the supply yourself or you need to convince a lot of people to delegate to you, which hopefully only works if you build services that use Nano and therefore, in both cases, you have a vested interest in ensuring the Nano network remains valuable.
On the other hand, Bitcoin miners have made large investments in ASICs which means they are strongly incentivized in the same sense, they want the Bitcoin network to remain valuable. Convincing either enough large Nano holders, or large swathes of Bitcoin hash power, would therefore be difficult.
However, wouldn't it, generally, not be easier to find hash power outside the large miners currently mining than it would be to find Nano to give yourself a majority? I'm thinking that to get a 51% majority in Nano as said earlier you need to buy up enough of the outstanding Nano, or convince holders with a vested interest in the value of the Nano network. For Bitcoin however, I could rent out a chunk of Amazon's computing power and set up my own temporary mining operation to compete with the mining pools currently available. It would still be expensive, but, I am assuming, less so than taking the Nano option (even with current market caps).
Is this a fair comparison? Or am I misrepresenting how easy it would be to get a Nano majority, or misrepresenting how difficult it would be to find alternative hash power to mine Bitcoin?
Edit: Comparing to Bitcoin because it has the most hash power, this goes for all PoW crypto.

My personal experience with Innosilicon A10 Pro (6G) 500Mh ASIC ethash miner

EDIT : This is about the 5G version, not the 6G.
Hello,
Since there is not much consumers tests online about the Innosilicon A10 (Ethmaster) Pro (5G) at 500Mh, I decided to share my personal experience through an "anonymous" account.
I bought it around April 2020, arrived in May but for personal reasons I was only able to turn it on this summer :(
The A10 costs me 3242 € + 70 € power supply (Innosilicon 1400W Power Supply) + shipping. I will not reveal where I bought it because this is not an ad, but it was through an european ASIC miner reseller.
I know Ethereum 2.0 is coming and I'm aware this is a gamble. I would not advise you to buy it now, especially knowing Eth 2.0 is really coming now, DeFi is pushing at the gates and I heard rumors there is a 750Mh version coming up.
So, it is my first ASIC miner, I did some ZEC mining with a 4 x 1080Ti mining rig two years go.
EDIT : EthToDoge pointed out in the comments that the A10 isn't an ASIC technically speaking
The A10 is basically a box crammed full of laptop GPUs and some custom firmware and made to look like the Bitcoin ASICS. [Check out the comments for more information]
The A10 mining chains reboots itself every 9 hours on average. When the A10 reboots, it goes into an autotuning mode which can take up to 2 hours, but usually around 1h. When in autotuning, it starts at 0Mh and goes to it's full speed after the autotuning, not mining much during this phase because the autotuning mode causes a lot of invalid shares, up to 20% and going down to 3% when tuning is completed.
The chains temperature are around 63°C, I don't know if this is the reason of the reboot. I'll try later on to get a better air flow. I fixed the temperature issue I had by placing in a better ventilated location, temperature is now around 53°C but that didn't fixed the reboot issue.
miner web interface, you can see the hashrate drop due to the random reboot
Performance settings
I tried balanced and factory modes, and I didn't saw much differences in the reported speed. In a near future I'll have a try with the performance mode but I will monitor the power consumption when trying since the A10 warns me to pay attention to that when I want to enable performance mode in the web interface. The performance mode consumes around 10% to 15% more electricity than the factory mode, without noticing any difference in the hashrate or stability. I didn't had proper tools to measure the power consumption, my A10 was plugged in an UPS and it's load went from 43% usage to 55% so I'm assuming the difference is the extra power consumption.
Changing performance settings causes the miner to go into autotuning.
Autoupdate
The firmware check is working, but I didn't manage to use the autoupdate. I had no problem to manually download the firmware and upload it, so not really a problem.
My device:
Type A10L
Controller Version g1
Build Date 15th of July 2020 06:13 AM
Platform Version a10l_20200715_061347

EDIT : I upgraded to the new firmware a10l_20200901_053652 but that didn't fixed the reboot issue.

Hashrate
I did some monitoring of the A10, here is how it looks

This is in factory mode on Ethermine (updated on Sept 24th) :
Average hashrate of 455Mh/s while running on ethermine
Hashrate of all chains + total hashrate

This is in balanced mode on Ethermine (updated on Sept 25th) :
Average hashrate of 449Mh/s while running on ethermine
Hashrate of all chains + total hashrate

This is in factory mode on Nanopool (updated on Sept 29th) :
Average hashrate of 502Mh/s while running on Nanopool (note that the double reboot in the middle of the graphic was caused by the change of ETH epoch, otherwise the average hashrate is around 512Mh/s.
Hashrate of all chains + total hashrate
As sweeperAA pointed out, the mining pool really matters.

A theory of why Ethereum is perhaps better "sound money" than Bitcoin.

The idea of Bitcoin's supremacy as "sound money" is very frequently thrown around by the biggest talking heads in the crypto world. I know I will get a lot of hate for suggesting that this theory is not only flawed, but it is straight up wrong. As unintuitive as it may sound to Bitcoin maximalists (no offense intended) I believe Ethereum is on the path to becoming the global leading asset and model for sound money... give me a chance to explain why.

  1. The idea that nothing can change Bitcoin's issuance schedule is a myth. There is absolutely no divine power controlling the supply of Bitcoin. Contrary to what is commonly asserted, Bitcoin's issuance protocol is not primarily driven by what is currently implemented. The real driver is consensus: the majority of network participants must agree that what is currently defined cannot be changed. There is an underlying assumption that the consensus would never want to change Bitcoin's issuance. On the surface this makes for a nice "sound money" narrative, but it is false premise and sticking to it could be ultimately detrimental. It presents a long term sustainability issue (the hope that somehow Bitcoin's base layer will scale enough to maintain security entirely through fees). It also completely dismisses the possibility that an unforeseen event could create pressure to change the issuance. If Bitcoin managed to create a consensus mechanism that did not rely on mining, it is very likely there would be consensus to reduce issuance. On the other hand, if some potentially catastrophic event would create incentives to increase the issuance, it would only make sense for the network to do so.
  2. Issuance flexibility is not fundamentally bad. Etheruem's approach to adjust the issuance according to the contextual circumstances has resulted in a faster rate of issuance reduction than what was originally defined in the protocol. The rate of issuance will continue to decrease as new developments allow for it to happen without compromising the network security. There is a very high probability that Ethereum will achieve a lower issuance rate than Bitcoin in the next two years, and it could possibly achieve zero issuance in the next five years. This would be a result of a successful implementation of PoS, sharding and EIP-1559.
  3. The root of all evil is Proof of Work. PoW is by far the primary cost of operating the Bitcoin network. It is the primary determinant of how much issuance is needed as a financial incentive to keep miners doing their thing. The very mechanism that secures the network's decentralization is unfortunately quite wasteful. The degree of decentralization is a direct result of how much random mathematical operations are being done by miners.
  4. There is a better way. Some people will take offense by the use of the word wasteful, and they claim that it is not because those mindless calculations are what is actually securing the network. However, its wasteful aspect becomes clear if there is a different way to achieve equal or superior decentralization without the need to crunch difficult computational problems. This just so happens to be embodied in Ethereum's design of Proof of Stake. It will drastically reduce the cost of securing the network, while providing at least 2-3% annual returns for the ownership of Ether. When Ethereum's issuance becomes lower than its staking rewards, it will effectively have achieved the same effect as having zero (or possibly negative) issuance.
  5. The value proposition of Ethereum 2.0 is unmatched. There is just absolutely no asset in the world that has a 2-3% self-denominated annual returns and just so happens to be rapidly appreciating. When wall-street's greed sees this, it will create the mother of all bubbles.
  6. Don't dismiss the flippening. On February 01 2018 Ethereum reached 70% of Bitcoin's marked cap (it was even closer if you account for the amount of lost bitcoins). That happened before DEFI, before proof of staking was within reach, before multiple effective layer 2 solutions were a thing, before wrapped Bitcoins and before the first signs of mass adoption were on the horizon (like integration with Reddit , VISA and potential to compete with SWIFT). Utility is a huge factor in driving prices, lets not forget how Silk Road played a key role into propelling Bitcoin's value. Yes, Ethereum crashed hard after the peak in 2018, but perhaps it is simply manifesting a higher volatility pattern that is reminiscent of Bitcoin's early years. Bitcoin's first 5 years were characterized by aggressive price swings, why should it be different for Etheruem (considering it is about 5 years younger than Bitcoin)? If the volatility patterns stands on this bull market, we will see a flippening.
So... do I think Etheruem will flip? Yes I do, but I still hold Bitcoin. No one has a crystal ball, and nothing is certain. Perhaps Etheruem will crash and burn, perhaps Bitcoin will become the next Yahoo, and perhaps they will both thrive in this new exciting crypto world.

What is the cost of BTC mining in China and Russia?

I know that the vast majority of Bitcoin mining is done in China due to the abundance of cheap electricity from hydroelectric dams. Out of curiosity, does anyone actually know what their effective cost per kWh is?
I’ve also read that a lot of that hash power could move to Russia (Siberia) due to some green initiatives by the Chinese government. Whether that’s true or not remains to be seen. Does anyone have any electricity cost data for Russia?
Thanks.

INT Mainnet 4.0 – Exploring Smart Contract Application

INT Mainnet 4.0 – Exploring Smart Contract Application
https://preview.redd.it/01z95tzhd6y51.png?width=900&format=png&auto=webp&s=f790a6044e0d915e23f8b543591ce65d6c16331a
In our last article, we introduced WASM-related issues during INT Mainnet 4.0 development. In this article, we will discuss the application of smart contracts.
In the cryptocurrency world, we define smart contracts as applications or programs that run on the blockchain. Generally, they are a set of digital protocols with specific rules, which are enforced on the network. These rules are predefined by computer source code, which is copied and executed by all network nodes. The Bitcoin protocol supports smart contracts, and it has become even more popular since Vitalik Buterin, the co-founder of Ethereum, made Ethereum the most advanced platform to support them. Smart contracts have many features such as being deterministic, real-time, autonomous, observable, verifiable, and decentralized. Also, smart contracts have broad application prospects in digital payments, financial assets, cloud computing, the Internet of Things, and the shared economy.

Digital identity

Smart contracts allow users to build user-centric personal networks with their digital identity, such as personal digital reputation and digital assets. The NBA Nets players Spencer Dinwiddie issued the first personal crypto bond of a professional player in history, which we now refer to as a "social token”. Among the social tokens, WHALE, with the highest market capitalization, is worth more than $43 million. When diluted, it has a market capitalization of over $100 million. Smart contracts can also specify which personal data could be shared with others, automating the processing of records, improving data transparency and reducing service costs.

Security

The securities process is digitalized based on smart contracts. It used for capitalized equity structure management and greatly simplify its process, such as supporting private companies to pay dividends, stock splits, and liability management automatically. Blockchain securities company (Symbiont) promotes the use of encrypted blockchain signatures for stock certificates.

Finance trade

Smart contracts simplify international commodity transfers process for higher asset liquidity. Initiating credit certification and trade payment process automatically will create a more efficient and less risky process between customers, suppliers and financial institutions. In addition, smart contracts ensure transaction security. When the condition triggers the execution condition of the smart contract, it is automatically executed according to a previously target and cannot be withdrawn or terminated once executed, thus ensuring the safety of both parties' assets. In the event of a conflict, these immutable records can be used to trace the execution of the contract at that time and provide strong evidence for conflict resolution.

Internet of Things

Using smart contracts to create a service market between devices and create a decentralized and shared economic application that not only protects privacy but also reflects the value of digital assets, while promoting the sharing of services and resources. At present, Internet of Things (IoT) includes billions of nodes that share data through the Internet, applications that integrate the IoT, blockchain, and smart contract, physical devices supported by the IoT or personal properties. Currently in China, people can rent, sell or share some devices, such as shared bicycles, shared power banks, and shared cars, without intermediaries.

Supply-chain

Smart contracts can provide greater visibility for every cycle in the supply chain, simplify multiple institutional systems, coordinate with IoT devices, track managed assets and products, and reduce the risk of fraud and theft. For example, Everledger and IBM have used blockchain in the supply chain to increase its visibility.

Smart insurance

Insurance contracts under the smart contract system are all digitized, stored in the blockchain ledger, and cannot be tampered with. At the same time, the insurance claims process is automated to improve the efficiency of processing. Insurance business based on smart contracts can provide intelligent customization services, which can automatically match the best insurance plan according to the type of insurance, time, term, claims history, etc., greatly reducing the service costs of the traditional insurance industry. For example, we can use smart contracts to record driver conditions, driving records, laws and regulations. When a traffic accident occurs, relevant data is automatically uploaded to the Internet, and the contract automatically executes the process of verification, claim and compensation. The insured’s driving records, vehicle conditions, and past accidents are all recorded in the database. The smart contract automatically retrieves relevant data to process insurance events.

Distributed computing

Distributed computing based on smart contracts has broad application prospects and practical significance. There are tens of thousands of nodes with computing power around the world that access digital currency networks (such as the Bitcoin network) for mining. A distributed computing network can intelligently match nodes (computing resource suppliers) and customers (computing resource demanders), fully develop and utilize existing network computing resources, simplify computing service process, and reduce computing service costs.
2020 witnessed the birth of many well-known Defi projects across a wide range of industries, but the core of the projects were all liquidity mining projects based on smart contracts. Uniswap, a decentralized exchange, breaks the dependence of users on centralized exchanges, and will be more widely used in the future for more specific and detailed places. In addition, the NFT (non-fungible tokens) involved in the field of encrypted collections and the social tokens are gradually getting more development opportunities, and these specific applications are also good development directions.

Conclusion

We are upgrading the performance of INT mainnet 4.0, which will be faster, have lower fees, be suitable for high-frequency trading, and enable the development of more complex smart contract applications. We look forward to developing different types of smart contract applications in different use-cases and industries in the INT ecosystem to fulfil specific development needs, solve practical problems, and aim for wider application adoption.

What is bitcoin mining

What is bitcoin mining
"What is Bitcoin mining" is an important question that should be answered in a simple way. Bitcoin mining is basically reviewed as the process of producing new BTC by solving a computational puzzle. BTC mining is essential in order to maintain the ledger of transactions upon which BTC crypto is based. Generally, miners are serving the whole BTC community in a way that revolves around confirming every transaction and making sure that every single one of them is legitimate. Attackers sometimes use phishing techniques for the purpose to trick victims into clicking links that load crypto coin mining code on their systems and it is also possible that they may also infect websites with malicious code.
How long would it take to mine 1 bitcoin
For those who are curious to know how long would it take to mine 1 bitcoin, it is completely good to know that regardless of the number of miners, it still takes 10 minutes to mine one BTC crypto coin, and at 600 seconds that is 10 minutes, all else being equal it will take 72,000 GW or 72 Terawatts of power to mine a BTC by using the average power usage provided by ASIC miners. If we talk about energy consumption, bitcoin mining hardware is an investment, and as such it has some costs. So, the more powerful your hardware is, the more electricity it is going to consume.
How to solo mine bitcoin
Before asking how to solo mine Bitcoin, first, understand that solo mining is a solo procedure using it the miner completely does the task of mining operations without any helping hand and the whole process is mainly done alone even without joining a pool. If you are about to consider the complexity involved in mining BTC, it’s very important to invest in the right kind of hardware and there are many characteristics to understand when picking the equipment that will best suit you, and one of them is the hash rate. If you are going to do the process of solo mining, you should make sure that you have connected your miner to your local BTC client so that you should get the best outcome to find a block on your own.

Technical: The Path to Taproot Activation

Taproot! Everybody wants to have it, somebody wants to make it, nobody knows how to get it!
(If you are asking why everybody wants it, see: Technical: Taproot: Why Activate?)
(Pedants: I mostly elide over lockin times)
Briefly, Taproot is that neat new thing that gets us:
So yes, let's activate taproot!

The SegWit Wars

The biggest problem with activating Taproot is PTSD from the previous softfork, SegWit. Pieter Wuille, one of the authors of the current Taproot proposal, has consistently held the position that he will not discuss activation, and will accept whatever activation process is imposed on Taproot. Other developers have expressed similar opinions.
So what happened with SegWit activation that was so traumatic? SegWit used the BIP9 activation method. Let's dive into BIP9!

BIP9 Miner-Activated Soft Fork

Basically, BIP9 has a bunch of parameters:
Now there are other parameters (name, starttime) but they are not anywhere near as important as the above two.
A number that is not a parameter, is 95%. Basically, activation of a BIP9 softfork is considered as actually succeeding if at least 95% of blocks in the last 2 weeks had the specified bit in the nVersion set. If less than 95% had this bit set before the timeout, then the upgrade fails and never goes into the network. This is not a parameter: it is a constant defined by BIP9, and developers using BIP9 activation cannot change this.
So, first some simple questions and their answers:

The Great Battles of the SegWit Wars

SegWit not only fixed transaction malleability, it also created a practical softforkable blocksize increase that also rebalanced weights so that the cost of spending a UTXO is about the same as the cost of creating UTXOs (and spending UTXOs is "better" since it limits the size of the UTXO set that every fullnode has to maintain).
So SegWit was written, the activation was decided to be BIP9, and then.... miner signalling stalled at below 75%.
Thus were the Great SegWit Wars started.

BIP9 Feature Hostage

If you are a miner with at least 5% global hashpower, you can hold a BIP9-activated softfork hostage.
You might even secretly want the softfork to actually push through. But you might want to extract concession from the users and the developers. Like removing the halvening. Or raising or even removing the block size caps (which helps larger miners more than smaller miners, making it easier to become a bigger fish that eats all the smaller fishes). Or whatever.
With BIP9, you can hold the softfork hostage. You just hold out and refuse to signal. You tell everyone you will signal, if and only if certain concessions are given to you.
This ability by miners to hold a feature hostage was enabled because of the miner-exit allowed by the timeout on BIP9. Prior to that, miners were considered little more than expendable security guards, paid for the risk they take to secure the network, but not special in the grand scheme of Bitcoin.

Covert ASICBoost

ASICBoost was a novel way of optimizing SHA256 mining, by taking advantage of the structure of the 80-byte header that is hashed in order to perform proof-of-work. The details of ASICBoost are out-of-scope here but you can read about it elsewhere
Here is a short summary of the two types of ASICBoost, relevant to the activation discussion.
Now, "overt" means "obvious", while "covert" means hidden. Overt ASICBoost is obvious because nVersion bits that are not currently in use for BIP9 activations are usually 0 by default, so setting those bits to 1 makes it obvious that you are doing something weird (namely, Overt ASICBoost). Covert ASICBoost is non-obvious because the order of transactions in a block are up to the miner anyway, so the miner rearranging the transactions in order to get lower power consumption is not going to be detected.
Unfortunately, while Overt ASICBoost was compatible with SegWit, Covert ASICBoost was not. This is because, pre-SegWit, only the block header Merkle tree committed to the transaction ordering. However, with SegWit, another Merkle tree exists, which commits to transaction ordering as well. Covert ASICBoost would require more computation to manipulate two Merkle trees, obviating the power benefits of Covert ASICBoost anyway.
Now, miners want to use ASICBoost (indeed, about 60->70% of current miners probably use the Overt ASICBoost nowadays; if you have a Bitcoin fullnode running you will see the logs with lots of "60 of last 100 blocks had unexpected versions" which is exactly what you would see with the nVersion manipulation that Overt ASICBoost does). But remember: ASICBoost was, at around the time, a novel improvement. Not all miners had ASICBoost hardware. Those who did, did not want it known that they had ASICBoost hardware, and wanted to do Covert ASICBoost!
But Covert ASICBoost is incompatible with SegWit, because SegWit actually has two Merkle trees of transaction data, and Covert ASICBoost works by fudging around with transaction ordering in a block, and recomputing two Merkle Trees is more expensive than recomputing just one (and loses the ASICBoost advantage).
Of course, those miners that wanted Covert ASICBoost did not want to openly admit that they had ASICBoost hardware, they wanted to keep their advantage secret because miners are strongly competitive in a very tight market. And doing ASICBoost Covertly was just the ticket, but they could not work post-SegWit.
Fortunately, due to the BIP9 activation process, they could hold SegWit hostage while covertly taking advantage of Covert ASICBoost!

UASF: BIP148 and BIP8

When the incompatibility between Covert ASICBoost and SegWit was realized, still, activation of SegWit stalled, and miners were still not openly claiming that ASICBoost was related to non-activation of SegWit.
Eventually, a new proposal was created: BIP148. With this rule, 3 months before the end of the SegWit timeout, nodes would reject blocks that did not signal SegWit. Thus, 3 months before SegWit timeout, BIP148 would force activation of SegWit.
This proposal was not accepted by Bitcoin Core, due to the shortening of the timeout (it effectively times out 3 months before the initial SegWit timeout). Instead, a fork of Bitcoin Core was created which added the patch to comply with BIP148. This was claimed as a User Activated Soft Fork, UASF, since users could freely download the alternate fork rather than sticking with the developers of Bitcoin Core.
Now, BIP148 effectively is just a BIP9 activation, except at its (earlier) timeout, the new rules would be activated anyway (instead of the BIP9-mandated behavior that the upgrade is cancelled at the end of the timeout).
BIP148 was actually inspired by the BIP8 proposal (the link here is a historical version; BIP8 has been updated recently, precisely in preparation for Taproot activation). BIP8 is basically BIP9, but at the end of timeout, the softfork is activated anyway rather than cancelled.
This removed the ability of miners to hold the softfork hostage. At best, they can delay the activation, but not stop it entirely by holding out as in BIP9.
Of course, this implies risk that not all miners have upgraded before activation, leading to possible losses for SPV users, as well as again re-pressuring miners to signal activation, possibly without the miners actually upgrading their software to properly impose the new softfork rules.

BIP91, SegWit2X, and The Aftermath

BIP148 inspired countermeasures, possibly from the Covert ASiCBoost miners, possibly from concerned users who wanted to offer concessions to miners. To this day, the common name for BIP148 - UASF - remains an emotionally-charged rallying cry for parts of the Bitcoin community.
One of these was SegWit2X. This was brokered in a deal between some Bitcoin personalities at a conference in New York, and thus part of the so-called "New York Agreement" or NYA, another emotionally-charged acronym.
The text of the NYA was basically:
  1. Set up a new activation threshold at 80% signalled at bit 4 (vs bit 1 for SegWit).
    • When this 80% signalling was reached, miners would require that bit 1 for SegWit be signalled to achive the 95% activation needed for SegWit.
  2. If the bit 4 signalling reached 80%, increase the block weight limit from the SegWit 4000000 to the SegWit2X 8000000, 6 months after bit 1 activation.
The first item above was coded in BIP91.
Unfortunately, if you read the BIP91, independently of NYA, you might come to the conclusion that BIP91 was only about lowering the threshold to 80%. In particular, BIP91 never mentions anything about the second point above, it never mentions that bit 4 80% threshold would also signal for a later hardfork increase in weight limit.
Because of this, even though there are claims that NYA (SegWit2X) reached 80% dominance, a close reading of BIP91 shows that the 80% dominance was only for SegWit activation, without necessarily a later 2x capacity hardfork (SegWit2X).
This ambiguity of bit 4 (NYA says it includes a 2x capacity hardfork, BIP91 says it does not) has continued to be a thorn in blocksize debates later. Economically speaking, Bitcoin futures between SegWit and SegWit2X showed strong economic dominance in favor of SegWit (SegWit2X futures were traded at a fraction in value of SegWit futures: I personally made a tidy but small amount of money betting against SegWit2X in the futures market), so suggesting that NYA achieved 80% dominance even in mining is laughable, but the NYA text that ties bit 4 to SegWit2X still exists.
Historically, BIP91 triggered which caused SegWit to activate before the BIP148 shorter timeout. BIP148 proponents continue to hold this day that it was the BIP148 shorter timeout and no-compromises-activate-on-August-1 that made miners flock to BIP91 as a face-saving tactic that actually removed the second clause of NYA. NYA supporters keep pointing to the bit 4 text in the NYA and the historical activation of BIP91 as a failed promise by Bitcoin developers.

Taproot Activation Proposals

There are two primary proposals I can see for Taproot activation:
  1. BIP8.
  2. Modern Softfork Activation.
We have discussed BIP8: roughly, it has bit and timeout, if 95% of miners signal bit it activates, at the end of timeout it activates. (EDIT: BIP8 has had recent updates: at the end of timeout it can now activate or fail. For the most part, in the below text "BIP8", means BIP8-and-activate-at-timeout, and "BIP9" means BIP8-and-fail-at-timeout)
So let's take a look at Modern Softfork Activation!

Modern Softfork Activation

This is a more complex activation method, composed of BIP9 and BIP8 as supcomponents.
  1. First have a 12-month BIP9 (fail at timeout).
  2. If the above fails to activate, have a 6-month discussion period during which users and developers and miners discuss whether to continue to step 3.
  3. Have a 24-month BIP8 (activate at timeout).
The total above is 42 months, if you are counting: 3.5 years worst-case activation.
The logic here is that if there are no problems, BIP9 will work just fine anyway. And if there are problems, the 6-month period should weed it out. Finally, miners cannot hold the feature hostage since the 24-month BIP8 period will exist anyway.

PSA: Being Resilient to Upgrades

Software is very birttle.
Anyone who has been using software for a long time has experienced something like this:
  1. You hear a new version of your favorite software has a nice new feature.
  2. Excited, you install the new version.
  3. You find that the new version has subtle incompatibilities with your current workflow.
  4. You are sad and downgrade to the older version.
  5. You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
  6. You tearfully reinstall the newer version and figure out how to get your lost productivity now that you have to adapt to a new workflow
If you are a technically-competent user, you might codify your workflow into a bunch of programs. And then you upgrade one of the external pieces of software you are using, and find that it has a subtle incompatibility with your current workflow which is based on a bunch of simple programs you wrote yourself. And if those simple programs are used as the basis of some important production system, you hve just screwed up because you upgraded software on an important production system.
And well, one of the issues with new softfork activation is that if not enough people (users and miners) upgrade to the newest Bitcoin software, the security of the new softfork rules are at risk.
Upgrading software of any kind is always a risk, and the more software you build on top of the software-being-upgraded, the greater you risk your tower of software collapsing while you change its foundations.
So if you have some complex Bitcoin-manipulating system with Bitcoin somewhere at the foundations, consider running two Bitcoin nodes:
  1. One is a "stable-version" Bitcoin node. Once it has synced, set it up to connect=x.x.x.x to the second node below (so that your ISP bandwidth is only spent on the second node). Use this node to run all your software: it's a stable version that you don't change for long periods of time. Enable txiindex, disable pruning, whatever your software needs.
  2. The other is an "always-up-to-date" Bitcoin Node. Keep its stoarge down with pruning (initially sync it off the "stable-version" node). You can't use blocksonly if your "stable-version" node needs to send transactions, but otherwise this "always-up-to-date" Bitcoin node can be kept as a low-resource node, so you can run both nodes in the same machine.
When a new Bitcoin version comes up, you just upgrade the "always-up-to-date" Bitcoin node. This protects you if a future softfork activates, you will only receive valid Bitcoin blocks and transactions. Since this node has nothing running on top of it, it is just a special peer of the "stable-version" node, any software incompatibilities with your system software do not exist.
Your "stable-version" Bitcoin node remains the same version until you are ready to actually upgrade this node and are prepared to rewrite most of the software you have running on top of it due to version compatibility problems.
When upgrading the "always-up-to-date", you can bring it down safely and then start it later. Your "stable-version" wil keep running, disconnected from the network, but otherwise still available for whatever queries. You do need some system to stop the "always-up-to-date" node if for any reason the "stable-version" goes down (otherwisee if the "always-up-to-date" advances its pruning window past what your "stable-version" has, the "stable-version" cannot sync afterwards), but if you are technically competent enough that you need to do this, you are technically competent enough to write such a trivial monitor program (EDIT: gmax notes you can adjust the pruning window by RPC commands to help with this as well).
This recommendation is from gmaxwell on IRC, by the way.

Happy Halloween - Updated Audit Status of Canadian Cryptocurrency Exchanges

Masks meant something different one year ago when I posted the highly popular “Happy Halloween - Audit Status of Canadian Cryptocurrency Exchanges”. Since then,
  1. We’ve had 20 more cryptocurrency exchange incidents globally.
  2. Canadian exchanges have seen massive progress - in at least a couple of exchanges.
  3. We’ve seen the collapse of Einstein which took millions of dollars more from Canadians. And we saw the OSC crackdown on the inflated trading volume on CoinSquare.

Blockchain provides the full ability for exchanges to prove asset backing, yet we continue to have to guess which platforms are backed. In an effort to help Canadians find the exchanges which are most transparent, we divide platforms into 5 categories:
If Proof of Reserve or another form of verification was standard on all exchanges, people like Gerald Cotten and Dave Smilie wouldn’t have been able to pull off massive fraud, and cases such as Einstein would have been known long before it resulted in insolvency. Supporting exchanges that don’t provide public validation or transparency is supporting fraud. Even if the platform is 100% honest, they are setting a dangerous standard that enables other fraudsters to hide in plain sight.

Dead Platforms/Incidents

FlexCoin - As “the world's first bitcoin bank” that’s “not a true bank”, FlexCoin provides “a central location for all of your bitcoins”. “Bitcoins deposited with flexcoin will be stored on [thei]r secure servers” so you can “send bitcoins to non-technical individual[s] via e-mail”. Unlike blockchain, “flexcoin to flexcoin transfers are free”.
MapleChange - “[S]wift, reliable and to-the-point!” “One of [their] primary concerns is security for [their] customers'' which is why “keys are cryptographically encrypted”. More Canadian than anyone! Excuse me while we hold the door open to our crypto! "[W]ithdraws(sic) are next to instantaneous", "rel[ying] solely on the aspect of swiftness"!
Canadian Bitcoins - Funds stored for convenience in a professional Rogers data center, which has the highest level of courtesy and customer service - always going above and beyond to provide expedient service whenever a request comes in!
CoinTradeNewNote - A “meticulously engineered Bitcoin Exchange” “focused on security and tak[ing] these risks seriously”. “[Y]ou don’t have to worry”, they have “90+% cold storage” and their “cold storage is fully insured by Xapo”. Plus, as “a registered Canadian corporation” they “leverage the good guys to fight the bad guys”.
Einstein - You can get “your money deposited and withdrawn faster than any other exchange”. As one customer said "With so many hacks and exit scams, it gives me confidence knowing Einstein is backed by hard-working people just like me." Just check the user experience on their subreddit from their "220,000+ satisfied customers".
EZ-BTC - As the world’s “most user-friendly and bespoke crypto currency management platform”, they have “strong security”. “All your coins are kept in cold storage. They’re safe.”. The presence of physical ATMs was one of the strategies to build customer confidence for their promised 9% annual return on stored funds.
QuadrigaCX - Operating since 2013, with “vast cryptocurrency reserves” right up to the end. "Bitcoins that are funded in QuadrigaCX are stored in cold storage, using some of the most secure cryptographic procedures possible." Even today some of the funds remain 100% secure in their cold storage!
If there are any others I missed, let me know!

No Verification Found

BitVo - Whether “Canada's premier cryptocurrency exchange” or merely “on a mission to become Canada’s premier cryptocurrency exchange”, we have to praise BitVo’s security for including “multiple signatures of a select group of trusted individuals” which are “not connected to the exchange platform or a network”. It is unfortunate that such common sense concepts are “proprietary” instead of the standard on all Canadian platforms. While assuring that they operate “on a full-reserve basis” and talking about “transparency”, the proof is lacking and nothing indicates it to have been verified externally or even internally. The withdrawal-based fee structure incentivizes users to keep funds “safe and secure” on the platform - which is “owned and operated by banking and security experts”. The “banking” side shows for sure in these hidden fine-print fees, which go well with transparency.
CoinField - Apparently no longer the "most secure trading platform in Canada" but now instead the “Best Bitcoin & Cryptocurrency Exchange In Canada” - based in Estonia and no longer having a Canadian office. They’re “fully regulated” in 193+ countries, except for the period between October 2019 and June 2020, when they weren’t even registered as an MSB. They offer a huge range of trading pairs except for the ones you need, with high liquidity except for the pairs that don’t have any, and you can withdraw and trade all of your funds as long as you leave a small amount behind at every stage.
CoinSmart - Not sure what "[i]ndustry leading cold storage" is, but luckily it’s “bank level”. No mention of multi-sig. They’re so "accountable to [their] clients, community and to each other" and "committed to being open and honest" that they don’t include any audit. Deposits are easy and withdrawals are fun - like a video game. Advance through each stage to prove your willpower, complete with warnings, SMS verification that doesn’t display errors (but luckily you can change the number to anything at all without further verification), and even an elaborate high-resolution selfie requirement you have to email in. If you can’t complete or don’t feel comfortable sending info via email, your money is held hostage - no big deal at all really.
Coinut - As "the most secure cryptocurrency exchange", they provide “a comprehensive cryptocurrency exchange platform for trading cryptocurrencies”. (Not to be confused with a cryptocurrency exchange platform for trading coconuts.) They’ve been “running securely for about three years” “by storing cryptocurrencies offline” in a single “offline computer”. In addition to not using multi-sig and "not us[ing] USB drives, as the online computer may be infected with virus", they also don’t appear to use audits or any form of public verification.
NDAX - “Canada’s most secure trading platform” to "set the standard for the Canadian cryptocurrency industry". While NDax promotes “segregated accounts” and “95-98% of user funds in an offline, multi-signature wallet”, there’s nothing to indicate backing of assets on the platform. While apparently partnered with a Canadian bank, the bank is not revealed. No audit found but at least there’s a full-page risk disclosure and disclaimer. You can sleep peacefully knowing that they’re legally protected, even “for losses suffer(sic) to you as a result of any defaults of by(sic) insolvency of other Users.” What does that even mean? Apparently, even with their industry-record withdrawal fees, they couldn’t afford a legal team with proper grammar.
Newton - Newton was one of the first to announce third party custody. You should give your funds to Newton, because they’ll give them to Balance, and they’ll do this for free! And “[m]ultinational companies trust” Balance. According to the Balance terms, “the digital assets you purchase via the Platform are not protected by any government or other insurance”. "Prospective clients...will hold the entire liability associated with purchasing a Digital Asset Cache™️ and using [Balance] services, potentially including partial or total loss of capital." "Balance does not represent or guarantee that the Balance Platform will be free from loss, corruption, attack, viruses, interference, hacking, or other security intrusion, and Balance disclaims any liability relating thereto." "No data transmission over the Internet can be guaranteed to be 100% secure, and as a result [they] cannot ensure or warrant the security of any information you transmit to [them]." "You are solely responsible for maintaining the confidentiality and security of your Account." If someone else should “[w]ithdraw the digital assets in your DAC to [thei]r external digital wallets as soon as within the same business day.” "Balance shall not be responsible for any losses arising out of the unauthorized or other improper use of your Account." The security of Balance custodianship comes down to (a) proprietary “HSMs” tested by their team of experts are more secure than hardware wallets tested by thousands of teams of experts around the globe, (b) a standardized and documented system of physical security in facilities accessible to a select number of people is superior to a combination of unique physical security, exclusive signing procedure, and complete locational secrecy that could be employed separately by multiple reasonably competent individuals, and (c) placing your trust in the team of Newton, the team of Balance, and the security of a website is more secure than simply trusting a single team to manage the private keys in an offline multi-sig fashion.
While Balance has an extensive page on security and internal controls, I was unable to locate any audit nor verification that the assets on Newton or custodian Balance are actually fully backed against deposits. From the demo page, we can see that Newton has visibility to see their balances on Balance, so at least Dustin and the team can check diligently and make sure they aren’t taken. Why not give some of that visibility to your customers? Why has Newton, which has been a leader in so many other areas (“commission-free”, working to get the best rates, etc…) not been a leader in putting together any level of public visibility to the backing of customer funds on their platform?

Apparent Verification

CoinBerry - CoinBerry uses the best practice of offline multi-sig for the storage of all customer funds, a set-up that, to date, has a breach-less record historically. Assuming the private keys are properly managed by separate trained people, CoinBerry client funds are thus stored in what’s essentially a giant cold storage wallet, with all withdrawals handled and verified by multiple people before being approved. However, this model is still subject to the platform being tricked into releasing funds as may have happened in August 2020. What they haven't done is transparently admitted and explained how the breach occurred, which can be an opportunity to highlight security improvements and help other platforms avoid similar issues. Instead, they've recently purchased insurance to cover future incidents. It's hard to judge from a few excerpts of what’s likely a multi-page (or even a multi-chapter) policy, but it would be the first time that insurance has ever paid out in the history of cryptocurrency. A multi-platform insurance strategy could be cheaper, more comprehensive, and more likely to pay out than third party insurance.
CoinBerry is “trusted by Canadian Municipalities”, a deal that enabled “the first payment of property taxes with Bitcoin in Canadian History”. They reportedly also “undergo annual 3rd party financial statement audits”. From records, these appear to be conducted by the firm MNP which is an accounting firm. CoinBerry has not, however, publicly declared themselves to be “fully-backed”, nor have they published any verification on the backing level of funds on the platform. Rather the audits are “secret”. This is concerning given the large referral bonuses paid out by the platform to new customers (including a popular $25 referral bonus for purchasing $50 of bitcoin), multiple issues with withdrawal delays, including one affecting hundreds of customers earlier this year, and the slow increase to their “fair pricing and industry-leading low fees.” Fees have gone from 0.5% to 1%, to a tiny sentence about “adding a margin, or spread, of between 0% and 2% to the rate offered by [thei]r liquidity sources”. Luckily, they “don’t hide fees across your trading experience.” In case you should sign up and find that (up to 2%) rate to be too high, “[a]ccounts requesting a withdrawal of Fiat or Crypto currency in original form, without conducting a trade will be...charged an account maintenance fee calculated as the larger of $25 or 5% of the total amount requested.” You will also need to pay additional “mining fees for crypto withdrawals”, which significantly exceed typical transaction costs and are only mentioned in the fine print of their fees page. CoinBerry has publicly expressed agreement that you should not store funds on cryptocurrency exchanges including their own. Neither their insurance nor world-class security will do anything whatsoever if their platform goes insolvent.
CoinSquare - CoinSquare has had a rough year, most notably with being publicly declared as having inflated trading volume and having to pay multi-million dollar fines. As usual, the Reddit community was already on top of this and apparently, some staff at the company were even open about it. Ironically, one could argue that their dishonest practice did more to stand up to Quadriga than regulators ever did, may have saved thousands of Canadians from losing their funds, and may even have been a key factor in bringing Quadriga down. It remains to be seen what will become of the shell of one of Canada's oldest exchanges. It would be the ultimate in poetic irony if the actions of the OSC to protect CoinSquare investors ultimately destroyed the full value of their investment. If that plays out, I'm sure they will heap praise on the OSC for so publicly and fragrantly shaming CoinSquare for a practice which was similarly employed on other exchanges globally and which they'd already voluntarily ceased months prior to the conclusion of the 6-figure investigation and 7-figure fines.
That said, CoinSquare already had a lack of visibility into their security practices, which they describe as “100% proprietary”. This would imply the team at CoinSquare is smarter than established security standards by experts all around the world at protecting your funds, contradicting previously reported incidents. They describe “SSL and 2FA”, which are more or less standard features of all exchanges. A “95% cold storage” policy is low compared to many other platforms, and it doesn’t appear to be mentioned whether multi-sig is being employed or not. And of course, their apparent regular audits are not public (allegedly by “a national accounting firm whose identity is protected under an NDA"). They’ve routinely described themselves as solvent rather than fully backed.
Kraken - A kraken is “an enormous mythical sea monster”, and likewise Kraken, the exchange, is enormous, the largest and oldest exchange platform in North America. Kraken recently achieved the momentous accomplishment of becoming the first cryptocurrency exchange to be a regulated bank by completing a charter in the state of Wyoming. Kraken calls itself the “most trusted cryptocurrency exchange” and apparently “provides world class financial stability by maintaining full reserves, healthy banking relationships and the highest standards of legal compliance”. While many individual Kraken customers have been hacked, the platform overall never has, which is an impressive record.
Similarities abound further. According to legend, kraken exist off the coast of Norway. According to alleged court papers, Kraken operated illegally in the state of New York. Should you encounter a kraken, you may be best to leave silently. If you should work at the counter for Kraken, you may be legally silenced. One of the former employees for Kraken alleges wrongful dismissal and that the bank accounts of Kraken are actually running millions of dollars short of where they should have been. But don't worry - Kraken’s website features a Proof of Reserve page, stating that “[o]ver the past several weeks, Kraken has successfully developed and completed an industry-leading, independent, cryptographically-verified audit.” But the page was written in 2014 and among the long list of limitations, the process does not enable any validation on the blockchain. Kraken hasn't done any validation or publishing of reserves in 6 years and counting.
NetCoins - Once upon a time, the cofounder of CoinTrader (sound familiar?) decided to found a new exchange - “Canada’s easiest, most trusted way to buy and sell crypto”. As they say on the FAQ, “[t]rading cryptocurrency is completely safe”. Having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” “Get verified in minutes!” While comforting to know that parent corporation BIGG Digital Assets is audited by Manning Elliott LLP and they have “[r]eal human beings you can get in touch with easily”, this doesn't make up for no visibility whatsoever into how funds are stored or what portions are backed.

Full Backing Report

There are only two exchanges in Canada meeting these criteria.
BitBuy - BitBuy has operated since 2016, and was the very first to get a “Proof of Reserve and Security Audit Report” from third party CipherBlade. Since that time, they’ve also established themselves as the first company to get two separate third party validations, with the second one from Blockchain Intelligence Group. The platform’s initial operation as a non-custodial “Express Trade” model lends additional credibility. Therefore, with now two independent third party reports, BitBuy maintains the title as the most transparent exchange in Canada.
However, “Bitbuy has moved its existing bitcoin holdings over to Knox”. You now have to trust both teams and platforms for the security of your funds. This is described by them as an “industry leading push for best practices”. Insurance is of course “subject to the full policy terms, conditions and exclusions”. And “Bitbuy will be Knox’s first platform partner”. Knox has never done this before for any other platform. Their security model is “a mouthful for most”, but let’s break down their pitch. They have “air-gapped specialized hardware”. So is a standard typical hardware wallet. It’s running “custom policy logic”, which could be a good or a bad thing depending on the logic. Their logic has probably been vetted by a single team of experts, which is a standard shy of most hardware wallet protocols vetted by thousands of experts globally. They use a “dual-control operational model”, which if you look up dual-control, it actually refers to the fact that the functionality of the module is simultaneously performing actions and being monitored”. It allows one to “experiment with the system so as to learn about its behavior and control it better in the future” which you can decide for yourself if that’s a good thing to have or not in the hardware that controls withdrawals of an active exchange platform. There is “offline transaction processing”, which again is a standard feature of a hardware wallet. “Geographically distinct facilities” is a good idea, though easily achieved by not storing all the private keys in the same place. Saying that the facilities “communicate in a closed network” is an interesting concept. How can you know that a network is closed? If the facilities are close together, they can be breached together. If far apart, someone can get in the middle. The network is no longer closed the moment any part of it is breached. I can go on and on and break down every one of their systems if I have to, but instead, I’ll quote their own security advice about “minimizing the attack surface of the entire key lifecycle”. The minimum attack surface for a private key is having an individual generate it secretly and securely using a process which is vetted by hundreds of security experts around the world, and not relying on a third party to have to control anything to do with that key. This is already available from most standard hardware wallets, with experts debating whether other advanced experts can find a way to extract the key with access to extremely sophisticated equipment and physical access to the hardware. The best and most efficient way to mitigate a weak or corruptible party is through multi-sig where all parties have to sign the transaction. Adding intermediary custodians instead means funds are lost when any one of them is breached, and when using the same in-house hardware as Knox does, any vulnerability on that hardware or supply chain can compromise multiple wallets at once.
Now, insurance. The policy isn’t public on its website. It gives high-level features only. What’s astounding is that “collusion” is considered a break-through, which says a lot about the state of third party insurance in the space. I requested an example policy from their team. Their response was that it was “proprietary” and that they only “go over it with serious buyers”. In other words, no one has visibility to the actual policy details of what’s really covered outside of BitBuy or Knox, and neither party has any incentive to present that information objectively. For now, until someone cares to prove me wrong, I’ll quote their own website, “[m]ost policies covering Bitcoin theft and loss fall short and provide a false sense of security”.
One of the issues with the BitBuy validation is that it offers no visibility whatsoever for customers to know if their balances were included in any of their third-party validations. As such, BitBuy could have excluded any number of customers and passed both verifications with flying colours. That's why it isn’t a full Proof of Reserve. Also, they stopped talking to me again. But I still believe that BitBuy is one of the least worst platforms, now with reserves verified by two separate third parties.
ShakePay - Firstly, congratulations. The formerly trustless raccoon has now got a third party validation - a key step forward. The ShakePay platform is incredibly good at marketing, with the most powerful “Shaking Sats” program to literally get thousands of Canadians to think about buying more cryptocurrency every single day, or at least to pay homage to their great raccoon mascot. More recently, ShakePay completed a security assessment provided by CipherTrace, and added further insurance. CipherTrace found that reserves appeared to be fully backed including extensive analysis of the transactions and provided data.
ShakePay could be upfront that they charge a market spread or list the buy and sell prices. Instead, they promote the service as “no fees” and list only one price for bitcoin or ethereum, the only coins they sell. To find the model you have to click through to a separate page. The spread and pricing information is only ever available from within a registered account. ShakePay does not offer any additional trading functionality or coins.
ShakePay states that the “majority of all digital currencies are stored securely offline”. The CipherBlade report found this ratio was at “93% of Bitcoin and 91% of Ethereum” in cold storage at the time of the report, though it “var[ies] periodically to some degree throughout the day”. The report refers to a “multi-signature wallet interface”, which they later call a “service to access its sending and receiving multi-signature wallets”, which apparently also “does not have control over cryptocurrency in the hot wallets”. This part doesn’t exactly make sense, as one would most likely consider “access” to a “sending” function as “control”. Apparently, this “not mentioned” service is “without any known security risks” and there are also “redundancy measures” in place as well. Whatever that means in the context of irreversible transactions is a mystery.
However, the majority of funds are no longer stored with ShakePay but have now been given to an undisclosed “trust company registered under the NYDFS”. The “variety of security protocols” in place here include “address whitelisting”, the only policy they are willing to disclose publicly “for security reasons”. While ShakePay won’t identify the third party, “CipherBlade can confidently conclude that Shakepay controls these cold wallets” even though “they are controlled by [the] cold storage provider” and “the cold storage provider ultimately holds the private keys”. ShakePay does receive “an account statement” “which includes applicable wallet addresses and balances held” and “[d]ata found on the blockchain was also in line with information found on these statements.” It will be interesting to see in one of many “quite unlikely” events what “the cold storage provider’s policy and Shakepay’s own policy” would cover, given that the details of both policies are completely secret. Luckily, “[t]he vast majority of Shakepay customers who purchase cryptocurrency on the Shakepay platform withdraw it promptly thereafter.”
It’s important to note that this report is not a Proof nor an Audit (as originally named). “The reviewer is not a professional accountant, and CipherBlade has not performed a professional financial audit or an audit of internal controls and expresses no assurance on the accounting records of Shakepay.” ShakePay was happy to remove “audit” but they still continue to insist on calling this a “proof”, when it’s not. They claim “Proof of Reserves can have a variety of setups” and they cited Nic Carter’s blog post, which also listed all the criteria for the proof, which they did not meet. In discussion with Nic (who is amazingly open to chat), he’s agreed “what they are doing is not a full PoR” and he “didn’t believe it would be a widely consulted thing - [he] was mostly doing it to encourage custodians to take PoR seriously”. The point of a “proof” and why it’s called a “proof” is because it leaves no doubt. A Proof of Reserve needs to prove the reserves - that funds exist on the blockchain, are spendable by the platform, and fully back the assets of any customer who bothers to check. ShakePay’s does not.

Proof of Reserves

Presently all platforms in Canada have refused to provide visibility to the public blockchain entries backing funds on their platform. They have refused to sign a proof of spendability for any funds they control. All claims and verifications have been against customer lists provided by the platform with no ability for any customers to validate they were included. This is a recipe for more Gerald Cottens and Dave Smillies.
I understand Proof of Reserve is not practical for all platforms. I was able to come up with an alternative that doesn’t require public blockchain visibility, could be implemented today using reputable third parties, and effectively validates all customers are included.

How We Could Have Safe Exchange Platforms In Canada

The first and largest issue has always been a lack of transparency. Far more funds have been lost to fraudulent platforms and wallet services than hacks. Honest platforms need to be giving greater visibility and certainty to their customers to make fraud obvious.
Secondly, no platform employing offline storage and multi-sig has ever been breached. We need to agree on the basic standards of what it takes to keep assets secure and create an environment where best practices are shared instead of hidden between platforms.
And thirdly, third party insurance incentivizes high fees, it limits coverage, and it does everything possible to avoid a payout. We need an organized insurance strategy that is run by platform operators and overseen with the full protection of Canadians in mind.


What’s possible is exciting, but not guaranteed. There are a lot of irreversibly horrible futures which are even more likely if we merely sit back and watch.
