A Detailed Summary of Every Single Reason Why I am Bullish on Ethereum

The following will be a list of the many reasons why I hold and am extremely bullish on ETH.

This is an extremely long post. If you just want the hopium without the detail, read the TL;DR at the bottom.

ETH 2.0

As we all know, ETH 2.0 phase 0 is right around the corner. This will lock up ETH and stakers will earn interest on their ETH in return for securing the network. Next comes phase 1 where the ETH 2 shards are introduced, shards are essentially parallel blockchains which are each responsible for a different part of Ethereum’s workload, think of it like a multi-core processor vs a single core processor. During phase 1, these shards will only act as data availability layers and won’t actually process transactions yet. However, their data can be utilised by the L2 scaling solution, rollups, increasing Ethereum’s throughput in transactions per second up to 100,000 TPS.
After phase 1 comes phase 1.5 which will move the ETH 1.0 chain into an ETH 2 shard and Ethereum will be fully secured by proof of stake. This means that ETH issuance will drop from around 5% per year to less than 1% and with EIP-1559, ETH might become a deflationary asset, but more on that later.
Finally, with ETH 2.0 phase two, each shard will be fully functional chains. With 64 of them, we can expect the base layer of Ethereum to scale around 64x, not including the massive scaling which comes from layer 2 scaling solutions like rollups as previously mentioned.
While the scaling benefits and ETH issuance reduction which comes with ETH 2.0 will be massive, they aren’t the only benefits. We also get benefits such as increased security from PoS compared to PoW, a huge energy efficiency improvement due to the removal of PoW and also the addition of eWASM which will allow contracts to be programmed in a wide range of programming languages, opening the floodgates for millions of web devs who want to be involved in Ethereum but don’t know Ethereum’s programming language, Solidity.

EIP-1559 and ETH scarcity

As I covered in a previous post of mine, ETH doesn’t have a supply cap like Bitcoin. Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself on the DeFi Pulse website.

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA player Spencer Dinwiddie tokenized his own NBA contract.)

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (Jitsi for the zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

TL;DR:

submitted by Tricky_Troll to ethtrader [link] [comments]

A detailed summary of every reason why I am bullish on ETH.

The following will be a list of the many reasons why I hold and am extremely bullish on ETH.

This is an extremely long post. If you just want the hopium without the detail, read the TL;DR at the bottom.

ETH 2.0

As we all know, ETH 2.0 phase 0 is right around the corner. This will lock up ETH and stakers will earn interest on their ETH in return for securing the network. Next comes phase 1 where the ETH 2 shards are introduced, shards are essentially parallel blockchains which are each responsible for a different part of Ethereum’s workload, think of it like a multi-core processor vs a single core processor. During phase 1, these shards will only act as data availability layers and won’t actually process transactions yet. However, their data can be utilised by the L2 scaling solution, rollups, increasing Ethereum’s throughput in transactions per second up to 100,000 TPS.
After phase 1 comes phase 1.5 which will move the ETH 1.0 chain into an ETH 2 shard and Ethereum will be fully secured by proof of stake. This means that ETH issuance will drop from around 5% per year to less than 1% and with EIP-1559, ETH might become a deflationary asset, but more on that later.
Finally, with ETH 2.0 phase two, each shard will be fully functional chains. With 64 of them, we can expect the base layer of Ethereum to scale around 64x, not including the massive scaling which comes from layer 2 scaling solutions like rollups as previously mentioned.
While the scaling benefits and ETH issuance reduction which comes with ETH 2.0 will be massive, they aren’t the only benefits. We also get benefits such as increased security from PoS compared to PoW, a huge energy efficiency improvement due to the removal of PoW and also the addition of eWASM which will allow contracts to be programmed in a wide range of programming languages, opening the floodgates for millions of web devs who want to be involved in Ethereum but don’t know Ethereum’s programming language, Solidity.

EIP-1559 and ETH scarcity

As I covered in a previous post of mine, ETH doesn’t have a supply cap like Bitcoin. Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself at: https://defipulse.com

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA Star Spencer Dinwiddie Tokenized His Own NBA Contract.

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (https://meet.jit.si/ for zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum.

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.

Coinmap and AirBitz are helpful to find local businesses accepting bitcoins. A good resource for UK residents is at wheretospendbitcoins.co.uk.
There are also lots of charities which accept bitcoin donations.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

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.

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.

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.
