I created Bitcoin Node Stats, a simple web app to log and view node statistics and status. Would like feedback on first demo version.

Demo: http://bitcoinnodestats.romgens.com
I created a proof of concept of a simple Bitcoin Node Stats web app. It stores raw node status every n minutes. Time plots are generated from this data. See demo in link on top.
This is just a small hobby project using Django, python-bitcoinlib, and D3js. You can find it on GitHub: https://github.com/bartromgens/bitcoinnodestats
Any and all feedback is welcome!
There are other node stats projects, such as http://statoshi.info, that have more features, and are much mature. bitcoinnodestats does not try to compete :) However, these are not always easy to install, or lose all data after a node restart. So there may be room for a simple Python/Django version.

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! :)

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. 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:

"My transaction is stuck, what to do?" - an explainer [DRAFT]

In the last days we have been experiencing a sharp rise in price, which is historically correlated with many people transacting over the Bitcoin network. Many people transacting over the Bitcoin network implies that the blockspace is in popular demand, meaning that when you send a transaction, it has to compete with other transactions for the inclusion in one of the blocks in the future. Miners are motivated by profits and transactions that pay more than other transactions are preferred when mining a new block. Although the network is working as intended (blockspace is a scarce good, subject to supply/demand dynamics, regulated purely by fees), people who are unfamiliar with it might feel worried that their transaction is “stuck” or otherwise somehow lost or “in limbo”. This post attempts to explain how the mempool works, how to optimize fees and that one does not need to worry about their funds.

TL;DR: Your funds are safe. Just be patient* and it'll be confirmed at some point. A transaction either will be confirmed or it never leaves your wallet, so there is nothing to worry about in regards to the safety of your coins.

You can see how the mempool "ebbs and flows", and lower fee tx's get confirmed in the "ebb" times (weekends, nights): https://jochen-hoenicke.de/queue/#0,30d
* if you are in hurry there are things like RBF (Replace By Fee) and CPFC (Child Pays For Parent), which you can use to boost your transaction fees; you will need an advanced wallet like Bitcoin Core or Electrum for that though. Keep also in mind that this is not possible with any transaction (RBF requires opt in before sending, f.ex). If nothing else works and your transaction really needs a soon confirmation, you can try and contact a mining pool to ask them if they would include your transaction. Some mining pools even offer a web-interface for this: 1, 2.
Here’s how Andreas Antonopoulos describes it:
In bitcoin there is no "in transit". Transactions are atomic meaning they either happen all at once or don't happen at all. There is no situation where they "leave" one wallet and are not simultaneously and instantaneously in the destination address. Either the transaction happened or it didn't. The only time you can't see the funds is if your wallet is hiding them because it is tracking a pending transaction and doesn't want you to try and spend funds that are already being spent in another transaction. It doesn't mean the money is in limbo, it's just your wallet waiting to see the outcome. If that is the case, you just wait. Eventually the transaction will either happen or will be deleted by the network.
tl;dr: your funds are safe

How is the speed of confirmations determined in bitcoin?

Open this site: https://jochen-hoenicke.de/queue/#0,2w
Here you see how many transactions are currently (and were historically) waiting to be confirmed, i.e how many transactions are currently competing with your transaction for blockspace (=confirmation).
You can see two important things: the differently coloured layers, each layer representing a different fee (higher layer = higher fees). You can point at a layer and see which fees (expressed in sat/byte) are represented in this layer. You can then deduct which layer your own transaction is currently at, and how far away from the top your position is (miners work through the mempool always from the top, simply because the tx's on top pay them more). You can estimate that each newly mined block removes roughly 1.xMB from the top (see the third graph which shows the mempool size in MB). On average, a new block is produced every ten minutes. But keep in mind that over time more transactions come into the mempool, so there can be periods where transactions are coming faster than transactions being “processed” by miners.
The second important observation is that the mempool "ebbs and flows", so even the lower paid transactions are periodically being confirmed at some point.
In short: what determines the speed of a confirmation is A) how high you set the fees (in sat/byte), B) how many other transactions with same or higher fees are currently competing with yours and C) how many transactions with higher paid fees will be broadcast after yours.
A) you can influence directly, B) you can observe in real time, but C) is difficult to predict. So it's always a little tricky to tell when the first confirmation happens if you set your fees low. But it's quite certain that at some point even the cheap transactions will come through.

So what happens if my transaction stays unconfirmed for days or even weeks?

Transactions are being broadcast by the full nodes on the network. Each node can adjust their settings for how long they keep unconfirmed transactions in their mempool. That’s why there is not a fixed amount of time after which a transaction is dropped from the mempool, but most nodes drop unconfirmed tx’s after two weeks [IS THIS CORRECT?]. This means that in the absolute worst case the unconfirmed transaction will simply disappear from the network, as if it never happened. Keep in mind that in those two weeks the coins never actually leave your wallet. It’s just that your wallet doesn’t show them as “available”, but you still have options like RBF and CPFP to get your transaction confirmed with higher fees, or to “cancel” your transaction by spending the same coins onto another address with a higher fee.

Helpful tools to estimate fees for future transactions:

Here are some resources that can help you estimate fees when sending a bitcoin transaction, so you don't end up overpaying (or underpaying) unnecessarily. Keep in mind that in order to take advantage of this, you need a proper bitcoin wallet which allows for custom fee setting. A selection of such wallets you can find here or here.
The order here is roughly from advanced to easy.
1) https://jochen-hoenicke.de/queue/#0,24h
Here you can see a visualization of how many unconfirmed transactions are currently on the network, as well as how many were there in the past. Each coloured layer represents a different fee amount. F.ex the deep blue (lowest layer) are the 1sat/byte transactions, slightly brighter level above are the 2sat/byte transactions and so on.
The most interesting graph is the third one, which shows you the size of the current mempool in MB and the amount of transactions with different fee levels, which would compete with your transaction if you were to send it right now. This should help you estimating how high you need to set the fee (in sat/byte) in order to have it confirmed "soon". But this also should help you to see that even the 1sat/byte transactions get confirmed very regularly, especially on weekends and in the night periods, and that the spikes in the mempool are always temporary. For that you can switch to higher timeframes in the upper right corner, f.ex here is a 30 days view: https://jochen-hoenicke.de/queue/#0,30d. You clearly can see that the mempool is cyclical and you can set a very low fee if you are not in hurry.
2) https://mempool.space
This is also an overview of the current mempool status, although less visual than the previous one. It shows you some important stats, like the mempool size, some basic stats of the recent blocks (tx fees, size etc). Most importantly, it makes a projection of how large you need to set your fees in sat/byte if you want your transaction to be included in the next block, or within the next two/three/four blocks. You can see this projection in the left upper corner (the blocks coloured in brown).
3) https://whatthefee.io
This is a simple estimation tool. It shows you the likelihood (in %) of a particular fee size (in sat/byte) to be confirmed within a particular timeframe (measured in hours). It is very simple to use, but the disadvantage is that it shows you estimates only for the next 24 hours. You probably will overpay by this method if your transaction is less time sensitive than that.
4) https://twitter.com/CoreFeeHelper
This is a very simple bot that tweets out fees projections every hour or so. It tells you how you need to set the fees in order to be confirmed within 1hou6hours/12hours/1day/3days/1week. Very simple to use.
Hopefully one of these tools will help you save fees for your next bitcoin transaction. Or at least help you understand that even with a very low fee setting your transaction will be confirmed sooner or later. Furthermore, I hope it makes you understand how important it is to use a wallet that allows you to set your own fees.

Decentr ($DEC) - foundational cross-chain and cross-platform DeFi protocol

  1. SUMMARY
Decentr is a protocol designed to make blockchain/DLT mainstream by allowing DeFi applications built on various blockchains to “talk to each other”. Decentr is a 100% secure and decentralised Web 3.0 protocol where users can apply PDV (personal data value) to increase APR on $DEC that users loan out as part of of our DeFi dLoan features, as well as it being applied at PoS when paying for stuff online. Decentr is also building a BAT competitor browser and Chrome/Firefox extension that acts as a gateway to 100% decentralised Web 3.0
Allows DeFi Dapps to access all Decentr’s dFintech features, including dLoan, dPay. Key innovation is that the protocols is based on a user’s ability to leverage the value of their data as exchangeable “currency”.
  1. KEY CONCEPTS

  1. REVENUE MODEL
A fee is charged for every transaction using dPay whereby an exchange takes place between money (fiat and digital) and data, and vice versa, either as part of DeFi features or via a dApp built on Decentr. They are launching pilot programmes in the following industries:
  1. Banking/PSP Industry: On Product launch, due to Decentr’s powerful PSP connections (including the worlds #2 PSP by volume), a medium-scale pilot program will be launched, which will seed the network with 150,000 PSP customers in primarily the Spanish/LAC markets, generating revenue from day one.
  2. “Bricks and Mortar” Supermarket/Grocery Industry: Decentr aims to ensure the long-term competitiveness of “bricks and mortar” supermarkets against online-only grocery retailers, such as Amazon, by a) building secure tech that allows supermarkets to digitise every aspect of their supply chains and operational functions, while b) allowing supermarkets to leverage this incredibly valuable data as a liquid asset class. Expected revenue by Year 5: $114Mn per year.
  3. Online Advertising Industry: Decentr’s 100% decentralised platform credits users secure data with payable value, in the form of PDV, for engaging with ads. The Brave browser was launched in 2012 and in 8 years has reached over 12 million monthly active users, accented by as many as 4.3 million daily active users.

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
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
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

Chainlink is the most overvalued "cryptocurrency" the world has ever seen

There are 1,000,000,000 LINK tokens, which gives it a market cap of $3.2 billion.
If you remove Tether, that would place it #6 as the most valuable "cryptocurrency". If you remove XRP, which is also not a cryptocurrency, it would place it #5. If you merge bitcoin forks, it would be #3, right under Ethereum.
Its current position is #11 according to CoinMarketcap, but that's because 650,000,000 tokens are owned by the team. Those tokens are not locked, nor legally bound by any agreement to not be sold. In fact the team has already started dumping them. They are literally circulating by any technical or legal definition, but for some reason CoinMarketcap decides to mislead investors and say they are not circulating. (https://beincrypto.com/chainlink-team-accused-of-dumping-530-million-in-link-tokens-over-six-weeks/)
The team promises in its whitepaper that half those tokens will be "rewards for nodes", but why would you trust the team? They've lied countless times. For example when they plaster in their marketing everywhere that their oracles are decentralized (they are not), Vitalik himself says so. The only "consensus algorithm" they use is to KYC each node manually. (https://web.archive.org/web/20200416103509/https://www.reddit.com/LINKTradecomments/fyxc23/whats_up_with_vitalik_constantly_bashing/fn35ae0/)
They've also lied about many partnerships. For example, they've said several times that they work with Swift, which is not true. They won some Swift competition in 2016, and radio silence since then. They still claim to be working with Swift today, but they conveniently removed it from their website not long ago. (https://web.archive.org/web/20190820085402/https://chain.link/)
They also claim to be working with Google, which is also a lie. They did 1 blog post 1 year ago, which was basically a thinly veiled ad for Google Cloud services. It was provably neither a partnership nor integration. The Google employee never even ran a node on mainnet. Yet the team constantly boasts about "working with Google". (https://web.archive.org/web/20190820085402/https://chain.link/)
They did the same with Oracle Cloud. Fernando (the Oracle employee that organized the "partnership") bragged about holding LINK after it pumped, got demoted, and all the Oracle startups that were supposed to be part of the "partnership" turned out to be dead or fake companies. It was at best a PR stunt for Oracle Cloud, at worst insider trading by Oracle employees. (https://web.archive.org/web/20200114062507/https://twitter.com/fribeiro1/status/1213946909464973316)
Chainlink has dozens of other "partnerships". I don't have time to investigate all of them, but all the ones I looked into were basically fake. (And by fake I mean they are grossly exaggerated, the tweets and blogposts are real)
As of today, even though they are the highest valued non-bitcoin, non-ethereum cryptoccurency in the world, the only project using their centralized KYC oracles are Synthetix (according to someone from their team). (https://web.archive.org/web/20200416104122/https://www.reddit.com/Chainlink/comments/fdwaad/request_examples_of_apps_built_with_chainlink/fjkhsjv/)
They apparently have countless big name companies "that will use Chainlink soon", but considering their testnet has been usable for close to 2 years, they have 1-2+ years old "partnerships" that are still not using it, and that their MO is to lie as much as humanly possible, I doubt it's true.

[RF] Just another quiet Friday night

"You're fucking crazy John," the man in the black T-Shirt announced. "Seriously, you want to pretend to be a paedo, so you can lure in the FBI and fuck with them? That is some next level warped shit."
"Chill out dude. That was just an example. Doesn't have to be a paedo."
"I don't give a fuck. Anything that's gonna make them zero-day you is some dark shit that you can't just laugh off. And what if they chain the sploits? They'll bounce out of your sandbox and be kicking the door down in minutes."
"No, no, it's ok. Really. I bought these laptops from a heroin addict in another city. Totally untraceable. I've had the lid off and de-soldered the camera, microphone and wireless."
"That's no use, we've got to get online somehow. And when their payload fires they'll trace us through a ToR bypass."
"That's why we need three laptops. Physical separation. This one," he tapped the metallic blue case, "is the bait. It's a regular laptop, but it's only connection is a single wired Ethernet. The only route to the Internet is via this one," tap tap, "which is running hardened Kali and only connects via ToR."
"Seriously, you're going to actually do this?"
"Come on dude, I've always wanted to try. Live a little."
"What's the third one for?"
"It's hardened Kali too. We proxy everything from the bait browser through here. When they deliver their exploit we'll catch it here, do some reverse engineering, and get ready for the fun bit!"
"What the hell. But you're crazy man. And we never speak of this."
"Of course. Goes without saying."
"How do we start?"
"You get a proxy running on that. I'll get the ToR connection set up. I got a 4G dongle off the same guy."
John removed a small ethernet hub from his bag, connected its power but held off from plugging in the laptops. He connected the 4G dongle, started the ToR service and watch its status update. With the connection active he configured the iptables firewall so outbound traffic was permitted only through ToR. Cal started the intercepting proxy, exposed its listener and looked at John. "Ready" They both plugged into the hub, and Cal watched as John connected the bait laptop, accessed the proxy settings and linked it to the listener.
He accessed a non-descript site to check the setup. It loaded a little slowly, while the series of requests popped up on the intercepting proxy. "Are we sure it's going through ToR?" Cal asked. "Don't worry". "Seriously, show me a packet trace." John started a sniffer, gestured to Cal to refresh the bait browser, while a series of packets scrolled up the screen, all safely encrypted by ToR.
"So what now?" a pause "And definitely no paedo stuff. That's too dark to mess about with."
"Old school," John replied, "I guess it's a bit of a cliche. We go on the dark net and try to order a murder for BitCoin. We'll make it an American prosecutor, that'll get the FBI going."
Cal stared at him. But that didn't stop him typing and Cal watched with grim fascination as he navigated around dark net markets, registering accounts, searching vendors and sending onimous enquiries. Cal monitored the proxy, configuring ever more intricate filters to weed out the mundane.
They'd crossed a line of no return and complicit Cal joined in, weaving convincing tales in their messages, striking the right tone to complete their deception. This went on for hours, with no sign of any incoming exploits. Until the browser popped up with "Do you want to allow this site to access WebGL?"
"That's it," John smiled, "there's no way that site really uses WebGL. This is an exploit. Stands to reason too, we always knews that had huge attack surface." He was about to permit it, but Cal stopped him. "No, don't allow it. If we allow it, we'll just get a lame zero day that requires WebGL. Deny it and carry on. They'll send a better exploit soon enough."
The intensity increased, Cal identified the malicious code that had tried to access WebGL. But it was just a stager - no exploit there. John carried on his ruse, until he noticed the browser stutter. He grabbed Cal's arm, "this is it!" Fear in the room intensified. This was serious now, some hacker - be it FBI or otherwise - had control of the laptop right in front of them. "Carry on with the messaging Cal. If we stop now they'll know our game."
Cal typed into the bait laptop while John began to investigate the exploit delivery. He identified the malware quickly enough, and a lingering connection that could be to the command and control server. Alarmingly, it was transferring a lot of data in both directions, a detail he decided not to share with Cal. He loaded the malware into a binary analysis tool and begun the painstaking process of unpicking its workings. 20 minutes in he told Cal to stop. "That'll do. Sign off naturally and shut it down."
Cal joined him with the binary anaysis and gradually they formed a picture of its armory. "It's not like one I've seen before," Cal said, "it's tighter coded than a typical rootkit. Really could be FBI." John nodded. "You can see it repeatedly copying this string. That's gotta be a heap spray. And it looks like self-decrypting machine code. Yeah, that's the payload for sure. We can just plug our own in here."
"What if the exploit's been watermarked?" Cal interjected, "We don't know where they could have hidden one."
"Who cares? We're gonna deliver it anonymously anyway."
They worked industriously to decouple the exploit and payload, build a delivery mechanism, and soon they were ready to test it. They watched in delight as a fully-patched browser accessed their delivery site, churned the laptop's CPU, then registered a ping back on the console.
The next step was to incorporate a real payload.
"So what's it gonna do John?"
"Persist itself to disk, then sit quietly and await further instructions. I've got the C&C software figured out already, it was a fun project from long ago. What I need you to do is use BitCoin to rent a couple of dozen virtual servers in different data centres around the world."
As Cal started registering the servers, John used the third laptop to generate a public/private key pair. One by one, the servers came online, and John installed the C&C software, configuring each to only respond to instructions signed by their private key. On the 20th he told Cal to stop.
There was a sparkle in his eyes. "We're nearly there! Everything's in place."
"How are we going to deliver it?"
"That's why we had to do this today. I found something earlier. A cache poisoning vulnerability on a major site."
Cal stared at him. The chain was complete. This was not real.
They completed their final maneouvers. Scripted a mechanism to dynamically generate payloads containing a random sample of C&C servers. Uploaded the exploit delivery mechanism into the control cloud, and generated a list of exploit URLs. John accessed the vulnerable major site, saved the HTML code locally, and modified it to include an exploit URL. Then he exploited the cache poisoning flaw, so that every visitor - at least every visitor coming through that particular cache cluster - would receive not the legitimate site but his malicious modificiations.
They watched the C&C management console. Around the world, thousands of unsuspecting web users experienced an annoying pause while their web pages loaded. Each time, under the hood, the zero day exploit fired, the payload persisted itself to disk, and made a connection to their C&C network to receive further instructions. Each time a new node joined their botnet, a line was logged to their console, and soon the screen was scrolling uncontrollably.
John was elated, Cal terrified. Cal watched in horror as John repeated the cache poison process across multiple clusters in different data centres. The rate of scrolling on the C&C console exploded. John cancelled it with a smile.
"Lets just look at the numbers"
Running a grep count on the log showed over 900,000 payload activations. And their malware had been live for barely 15 minutes.
"What are you going to do with it?"
"That's for another day. Now, we cover our tracks."
John removed two USB drives from his bag. He created an encrypted container, and into it put his decoy. Some nudes of an office chick that had been circulating. Incriminating enough, but not the crown jewels. He then created a hidden container within the free space of the first container, using a very strong password. Into this hidden container he copied the private key for the C&C network. This key put him in control. The only way to control the botnot was having both the USB drive, and his strong password. He repeated the process for Cal, inviting him to choose his own passwords. When he handed over the drive, Cal held it like it was on fire.
He shut down the bait laptop, gesturing Cal to do the same with the proxy. Removed the hard drive and connected it via USB to the ToR relay. The ToR relay was unlikely to have been compromised that night, a trustworthy system he could use to erase the others. After a secure erase of both drives, then of the ToR relay itself, John started putting everything in a bag.
They left the hotel room in silence. Bag on the rear seat and John drove. Cal was acutely aware of the USB drive in his pocket, the angled corners pressing into his leg. He went out of town, down lanes Cal didn't recognise, and stopped by a chain link fence. They both got out, John retrieved the bag, and with a big hurl, launched it over the fence into the landfill.
Back home, John smoked a large joint of double zero hash and fell fast asleep. He awoke a few hours later. It almost felt like a dream. But he ran his fingers along the USB drive and remembered the sheer power it contained.

Weekly Wrap: This Week In Chainlink August 31 - September 6

Weekly Wrap: This Week In Chainlink August 31 - September 6

Chainlink Hackathon - September 7th - 27th!

We've already received over 300 developer signups from over 40 countries for the Chainlink Hackathon. Get ready to join one of the biggest blockchain developer events of the year and build the next top DeFi dApp with support from our world-class mentors and a chance to win over $40K prizes.

Announcements and Integrations 🎉

@synthetix_io is now fully #PoweredByChainlink, switching all its cryptocurrency and index synths to Chainlink's Price Reference Data due to its high-quality data, decentralization, & ability to scale the platform to secure more value.

Bitcoin smart contract platform @RSKsmart has successfully integrated Chainlink oracles via its @rif_os technology. This allows RSK developers to build smart contract applications connected to real-world data that are secured by the Bitcoin blockchain.

@01node is a new node operator supporting Chainlink's live Price Reference Contracts. As operators experienced in securing millions of USD for PoS chains, they bring added decentralization by running their own physical servers that further minimize cloud dependencies.

Decentralized lending protocol @useteller is live on testnet consuming Chainlink's Price Reference Data for ETH/USD, BTC/USD & LINK/USD. These price feeds help Teller ensure that all APR calculations for unsecured loans reflect real market conditions.

Telecommunications blockchain @QLCchain is integrating Chainlink to make its aggregated data available to smart contracts. This data can power new DeFi applications like automating payments between telco providers, tokenizing telco infrastructure & more.

Social reputation score provider @DecentrNet is integrating Chainlink to allow users to share their data in #DeFi dApps to obtain better interest & collateralization rates. Chainlink also helps Decentr make this key data available across any blockchain.

@opium_network is using Chainlink's USDT/USD Price Reference Data live on mainnet to launch the first credit default swap on a centralized stablecoin—USDT. This is another example of how Chainlink oracles are powering innovative DeFi products.

Blockchain card game @EtherLegends will use Chainlink VRF to power their random distribution of NFT-backed end-of-season rewards. These rare items will be awarded to top players at the end of the ongoing season with verifiable proof of fair distribution.

We’re thrilled to award a grant to @ensdomains from the Chainlink Community Grant Program: https://blog.chain.link/introducing-the-chainlink-community-grant-program/…, supporting them in developing human-readable names for oracle contracts, making Chainlink easily accessible to even more smart contract devs

Featured Videos & Educational Pieces 🎥

DeFi is disrupting finance and crypto by moving beyond tokens and wallets into sophisticated smart contract applications that allow p2p lending, liquidity mining, synthetic assets, derivatives, and more. DeFi pioneers Sergey Nazarov (Chainlink), Andre Cronje (yEarn), Stani Kulechoiv (Aave), and Kain Warwick (Synthetix) come together to explain DeFi’s remarkable growth on Ethereum, expansion into new markets, and the impact of live infrastructure, especially decentralized oracles, on DeFi protocols.

Chainlink Labs Chief Scientist Dr. Ari Jules gives a #SmartCon Keynote explaining how DECO helps Chainlink oracles liberate more web data for smart contracts, including identity records, financial data, accredited investor confirmation, supply chain logistics, and more. Using DECO to make this data available on-chain allows blockchains to enhance many enterprise use cases today while still retaining the key property of data confidentiality.

Chainlink-powered decentralized oracles provide smart contracts with definitive truth about the validity of real-world data. In this Keynote, Sergey Nazarov explains how Chainlink is using its secure and reliable oracles to expand the addressable market of smart contract applications into the trillions, thanks to opening up blockchain applications in DeFi, CeFi, Fintech, Web 2.0, and enterprise systems. He also discusses Chainlink’s new DECO acquisition and how it opens up access to web data for smart contracts while preserving data security and confidentiality.

Other SmartCon talks now posted include:
