CryptoPunks is a live dapp with a nicely designed web3 interface that can be used to introduce new people to the basic concepts and workings of Ethereum.

It's rare right now to find a web3 interface dapp live on mainnet. These guys have done a great job in making the app easy to use and understand. Even if you have no interest in acquiring a punk itself, I think it can be used to show new users the concepts and workings behind ethereum.

Eth 2.0 vs Polkadot and other musings by a fundamental investor

Spent about two hours on this post and I decided it would help the community if I made it more visible. Comment was made as a response to this
I’m trying to avoid falling into a maximalist mindset over time. This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
Can someone help me see the downsides of diversifying into DOTs?
I know Polkadot is more centralized, VC backed, and generally against our ethos here. On chain governance might introduce some unknown risks. What else am I missing?
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
Response:
What else am I missing?
The upsides.
Most of the guys responding to you here are full Eth maxis who drank the Parity is bad koolaid. They are married to their investment and basically emotional / tribal in an area where you should have a cool head. Sure, you might get more upvotes on Reddit if you do and say what the crowd wants, but do you want upvotes and fleeting validation or do you want returns on your investment? Do you want to be these guys or do you want to be the shareholder making bank off of those guys?
Disclaimer: I'm both an Eth whale and a Dot whale, and have been in crypto for close to a decade now. I originally bought ether sub $10 after researching it for at least a thousand hours. Rode to $1500 and down to $60. Iron hands - my intent has always been to reconsider my Eth position after proof of stake is out. I invested in the 2017 Dot public sale with the plan of flipping profits back to Eth but keeping Dots looks like the right short and long term play now. I am not a trader, I just take a deep tech dive every couple of years and invest in fundamentals.
Now as for your concerns:
I know Polkadot is more centralized
The sad truth is that the market doesn't really care about this. At all. There is no real statistic to show at what point a coin is "decentralized" or "too centralized". For example, bitcoin has been completely taken over by Chinese mining farms for about five years now. Last I checked, they control above 85% of the hashing power, they just spread it among different mining pools to make it look decentralized. They have had the ability to fake or block transactions for all this time but it has never been in their best interest to do so: messing with bitcoin in that way would crash its price, therefore their bitcoin holdings, their mining equipment, and their company stock (some of them worth billions) would evaporate. So they won't do it due to economics, but not because they can't.
That is the major point I want to get across; originally Bitcoin couldn't be messed with because it was decentralized, but now Bitcoin is centralized but it's still not messed with due to economics. It is basically ChinaCoin at this point, but the market doesn't care, and it still enjoys over 50% of the total crypto market cap.
So how does this relate to Polkadot? Well fortunately most chains - Ethereum included - are working towards proof of stake. This is obviously better for the environment, but it also has a massive benefit for token holders. If a hostile party wanted to take over a proof of stake chain they'd have to buy up a massive share of the network. The moment they force through a malicious transaction a proof of stake blockchain has the option to fork them off. It would be messy for a few days, but by the end of the week the hostile party would have a large amount of now worthless tokens, and the proof of stake community would have moved on to a version of the blockchain where the hostile party's tokens have been slashed to zero. So not only does the market not care about centralization (Bitcoin example), but proof of stake makes token holders even safer.
That being said, Polkadot's "centralization" is not that far off to Ethereum. The Web3 foundation kept 30% of the Dots while the Ethereum Foundation kept 17%. There are whales in Polkadot but Ethereum has them too - 40% of all genesis Ether went to 100 wallets, and many suspect that the original Ethereum ICO was sybiled to make it look more popular and decentralized than it really was. But you don't really care about that do you? Neither do I. Whales are a fact of life.
VC backed
VCs are part of the crypto game now. There is no way to get rid of them, and there is no real reason why you should want to get rid of them. They put their capital at risk (same as you and me) and seek returns on their investment (same as you and me). They are both in Polkadot and Ethereum, and have been for years now. I have no issue with them as long as they don't play around with insider information, but that is another topic. To be honest, I would be worried if VCs did not endorse chains I'm researching, but maybe that's because my investing style isn't chasing hype and buying SUSHI style tokens from anonymous (at the time) developers. That's just playing hot potato. But hey, some people are good at that.
As to the amount of wallets that participated in the Polkadot ICO: a little known fact is that more individual wallets participated in Polkadot's ICO than Ethereum's, even though Polkadot never marketed their ICO rounds due to regulatory reasons.
generally against our ethos here
Kool aid.
Some guy that works(ed?) at Parity (who employs what, 200+ people?) correctly said that Ethereum is losing its tech lead and that offended the Ethereum hivemind. Oh no. So controversial. I'm so personally hurt by that.
Some guy that has been working for free on Ethereum basically forever correctly said that Polkadot is taking the blockchain tech crown. Do we A) Reflect on why he said that? or B) Rally the mob to chase him off?
"I did not quit social media, I quit Ethereum. I did not go dark, I just left the community. I am no longer coordinating hard forks, building testnets, or contributing otherwise. I did not work on Polkadot, I never did, I worked on Ethereum. I did not hate Ethereum, I loved it."
Also Parity locked their funds (and about 500+ other wallets not owned by them) and proposed a solution to recover them. When the community voted no they backed off and did not fork the chain, even if they had the influence to do so. For some reason this subreddit hates them for that, even if Parity did the 100% moral thing to do. Remember, 500+ other teams or people had their funds locked, so Parity was morally bound to try its best to recover them.
Its just lame drama to be honest. Nothing to do with ethos, everything to do with emotional tribalism.
Now for the missing upsides (I'll also respond to random fragments scattered in the thread):
This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
A good quick intro to Eth's tech vs Polkadot's tech can be found on this thread, especially this reply. That thread is basically mandatory reading if you care about your investment.
Eth 2.0's features will not really kick in for end users until about 2023. That means every dapp (except DeFI, where the fees make sense due to returns and is leading the fee market) who built on Eth's layer 1 are dead for three years. Remember the trading card games... Gods Unchained? How many players do you think are going to buy and sell cards when the transaction fee is worth more than the cards? All that development is now practically worthless until it can migrate to its own shard. This story repeats for hundreds of other dapp teams who's projects are now priced out for three years. So now they either have to migrate to a one of the many unpopulated L2 options (which have their own list of problems and risks, but that's another topic) or they look for another platform, preferably one interoperable with Ethereum. Hence Polkadot's massive growth in developer activity. If you check out https://polkaproject.com/ you'll see 205 projects listed at the time of this post. About a week ago they had 202 listed. That means about one team migrated from another tech stack to build on Polkadot every two days, and trust me, many more will come in when parachains are finally activated, and it will be a complete no brainer when Polkadot 2.0 is released.
Another huge upside for Polkadot is the Initial Parachain Offerings. Polkadot's version of ICOs. The biggest difference is that you can vote for parachains using your Dots to bind them to the relay chain, and you get some of the parachain's tokens in exchange. After a certain amount of time you get your Dots back. The tokenomics here are impressive: Dots are locked (reduced supply) instead of sold (sell pressure) and you still earn your staking rewards. There's no risk of scammers running away with your Ether and the governance mechanism allows for the community to defund incompetent devs who did not deliver what was promised.
Wouldn’t an ETH shard on Polkadot gain a bunch of scaling benefits that we won’t see natively for a couple years?
Yes. That is correct. Both Edgeware and Moonbeam are EVM compatible. And if the original dapp teams don't migrate their projects someone else will fork them, exactly like SUSHI did to Uniswap, and how Acala is doing to MakerDao.
Although realistically Ethereum has a 5 yr headstart and devs haven't slowed down at all
Ethereum had a five year head start but it turns out that Polkadot has a three year tech lead.
Just because it's "EVM Compatible" doesn't mean you can just plug Ethereum into Polkadot or vica versa, it just means they both understand Ethereum bytecode and you can potentially copy/paste contracts from Ethereum to Polkadot, but you'd still need to add a "bridge" between the 2 chains, so it adds additional complexity and extra steps compared to using any of the existing L2 scaling solutions
That only applies of you are thinking from an Eth maximalist perspective. But if you think from Polkadot's side, why would you need to use the bridge back to Ethereum at all? Everything will be seamless, cheaper, and quicker once the ecosystem starts to flourish.
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
They are competitors. Both have their strategies, and both have their strengths (tech vs time on the market) but they are clearly competing in my eyes. Which is a good thing, Apple and Samsung competing in the cell phone market just leads to more innovation for consumers. You can still invest in both if you like.
Edit - link to post and the rest of the conversation: https://www.reddit.com/ethfinance/comments/iooew6/daily_general_discussion_september_8_2020/g4h5yyq/
Edit 2 - one day later PolkaProject count is 210. Devs are getting the hint :)

Yield farming thread

What is yield farming? Most broadly, it means getting some benefit for providing capital, usually in the form of tokens. Currently, there are three major different schemes:
  1. Staked funds aren't utilized in any way and tokens are distributed proportionally to what's staked (may be dai, weth, ycrv, or other tokens). Token price risk: zero. Token accrues, but even if it falls to zero you lose nothing. Smart contract/protocol risk: depends on the staking contract, usually low to zero. Contracts are usually simple modification of the first contract used by yearn (taken from synthetix), making analysis easy by only looking for differences. APR: may start high, but usually collapses fast to relatively low values as funds pour in.
  2. Providing liquidity in trading pools. Tokens are gained in return for providing liquidity for requested tokens on uniswap, balancer, curve, mooniswap. Token price risk: medium to high, depends on pool weights. See these two articles for details on how liquidity providing works: Uniswap - pool weight is always 50%/50% Balancer - arbitrary pool weights, down to 2% for one token. Can be multitoken, not just two. Smart contract security risk: medium to high. In addition to checking the (usually simple) staking contract, requires security analysis of the token contract. If it's possible to mint a very large amount of token, or someone has a hidden enormous stash, the attacker could clean the pool by dumping them at once. I'm aware of one scam called "YYFI" that did this - you can see the attacker successively getting DAI from the balancer pool. Fortunately for the victims, he wasn't very competent and did everything manually, giving time for people to withdraw. A more competent attacker would automate the pool cleaning process in a smart contract. APR: usually very high - upper three digits or four. It's rarely realized APR because it's calculated assuming that token price stays constant. If you think the token being distributed is undervalued definitely the best option to farm.
  3. Depositing and borrowing funds for defi. Currently utilized by compound and cream (a compound clone). Users get rewarded with tokens for lending and borrowing tokens. Token price risk: zero. Security risk: the most complex to analyze option of all, although Compound itself is definitely the safest defi dapp on ethereum.
Warning: gas fees are high. $10k is probably the minimum amount that makes sense for active manual farming, which still only makes sense for a more long-term farms like COMP or CRV, at the cost of not maximizing APR. I have spent over $3k in gas during the last two months by farming very actively. Below $100k, or if you don't want to spend a lot of time on this, it's probably best to deposit your funds into one of yearn vaults that yield farms for users. https://yearn.finance/vaults
A partial list of current yield farms (feel free to comment with more farms! I can edit and add them to this list):
  • COMP farming, the oldest one (I think?). Relatively low returns (58% on DAI), safe, no price risk. Efficient way to farm is to supply and borrow the same asset (can be done via instadapp) up to maximum leverage possible (with some margin for interest payments).
  • BAL farming, provide liquidity to BAL pools. Safe smart contracts (just don't deposit deflationary tokens). Price risk and APR depends on the pair. https://balancer.exchange/
    See returns for both balancer and compound at https://www.predictions.exchange/
  • YFV finance, one of the many clones of YFI. The seed pool is safe IF you withdraw before the staking period ends (see the security part). Current APR on stablecoins: 121%
  • CRV farming, providing liquidity to curve pools. Mostly safe - curve smart contracts tself are safe, but keep in mind if one of tokens in the pool collapses (renBTC is probably the riskiest) other tokens are going to get drained. You can see the current APR on https://dao.curve.fi/mintegauges. As of now, the highest APR is for compound pool - 105.27%. It's varying and there's complicated game with CRV voting that impacts it.
  • CREAM farming. CREAM is a clone of compound. It's definitely less safe than Compound. Initially, it launched with a direct control by one normal address, but recently they moved to a 5-of-9 multisig.
  • YFII, another YFI clone. Current APR 95%. https://yfii.finance/#/staking
  • Mstable, liquidity providing with stablecoins. APR about 50% (MTA + BAL). https://defirate.com/mta-yield-farming/
  • Zombie, meme token. Current APR is abysmal (33.5%) but token may unexpectedly pump, increasing it. There's a smart contract bug that, as long as rewardDistribution and owner aren't set to zero, potentially allows rewardDistribution to lock all staked funds (not steal). Makes zero sense as of today.
NEW
  • Sushi Swap - stake Uniswap LP tokens. Four digit APR, varying levels of price risk, depending on the pool. (added on 29 Aug UTC)
Analyzing security.
Edit: warning, a new type of scam just happened - degen.money site asked for token spending approval on the attacker's address, in addition to the (safe) contract's address. Always ensure you're approving a correct address.
Yield farms come and go. The key to earning high returns is to be agile and to jump fast into new farms, which requires manual analysis of security. Of course it's possible to yolo in without any analysis, but I don't recommend it. I'm going to show an example on two recent farming contracts (of the first type - funds just sit in contracts).
Original yearn staking contract. GRAP staking contract. Let's load two codes into a text diff tool, like this site. What interests us on the code level are changes relating to the withdrawal capability, which in the original code are limited to the withdraw() function. We can see that the only substantial change is the addition of the checkStart modifier which prevents both deposits and withdrawals if it's too early. As startime is set directly in source code and can't be modified anywhere, that change is safe - if it doesn't throw on deposit it's not going to throw on withdraw.
The next step is switch to the 'read contract' tab on etherscan and look at two variables: owner and rewardDistribution. In Grap's case, they lead to a timelock contract that requires all changes to wait for at least 24.5 hours - which makes any fund lockup extremely unlikely. At worst, we only have to look at the rewardDistribution contract once a day to see if there's any pending change.
GRAP farming is now finished with no security incidents.
Second example: YFV. This one is still active. Contract link. After comparing them we can see that changes are much more extensive. The withdrawal function also has the checkStart modifier, but that part is fine (ctrl-f to check if starttime can be modified somewhere else - it can't). What's the problem is the checkNextEpoch modifier. There's a lot of things there and three external contract calls (mint calls). If anything in there throws, withdrawal would become impossible. Dangerous. However, that only happens after the staking period ends, so withdrawing before block.timestamp >= periodFinish is relatively safe.
Another check is to look at the owner and rewardDistribution variables. Owner is set to zero, but where's rewardDistribution? Unfortunately, contrary to GRAP, it's private. It's possible to read it with the getStorageAt web3 api (although finding the index is more work - it's 3). However, the team has provided a link to the transaction in which they set rewardDistribution to 0 so it's fine.
In conclusion, as long as you don't hold the funds after the locking period ended there's no security risk here. The current period ends on Tue Sep 1 14:02:29 2020, UTC.

Polkadot (DOT) coin Price Prediction 2021

Polkadot (DOT) coin Price Prediction 2021
What is Polkadot?
Polkadot is a scalable, multi-chain technology that was developed by Gavin Wood, one of the co-founders of the Ethereum project. Basically Polkadot is a network that connects blockchains. The platform allows various blockchains to transfer messages, including value, and to share unique features.
The project main goal is to transform the existing structure of the Internet to Web3 – an absolutely innovative and decentralized network.
by StealthEX
The internal token of the Polkadot network is called DOT. This token allows owners to vote on possible changes to the protocol, which are automatically rolled out across the network if the consensus is reached. The DOT crypto also serves for staking and bonding purposes.
Today Polkadot is one of the TOP-5 cryptocurrencies by market capitalization.

Polkadot Statistics

Source: CoinMarketCap, Data was taken on 17 September 2020 by StealthEX
Current Price $5.28
ROI since launch 89.3%
Market Cap $4,499,688,210
Market Rank #5
Circulating Supply 852,647,705 DOT
Total Supply 987,964,778 DOT

Polkadot achievements and future plans

Recently the Polkadot project developers have the following main updates and news:
• The Polkadot Ecosystem Fund and the Polkadot Incubator were released.
• The Kusama network – an unaudited version of Polkadot was launched.
• The team introduced a new testnet for Polkadot and Kusama called Westend.
• On 26 May 2020 Web3 Foundation launched the initial version of Polkadot.
• The Polkadot team started the first vote on the fledgling Polkadot network.
• Polkadot’s parachain testnet called Rococo was introduced.
• A huge number of workshops, both online and in-person were given around the world on a variety of topics — validation, Polkadot basics, Kusama, addresses, security, and Substrate.

What to expect in the future?

Currently, the Polkadot project is on the phase of “Enabling Balance Transfers and Denomination Day”. Once governance enables parachain auctions and XCMP, Polkadot will have a fully functional Relay Chain. After that, the token holders will decide how the project will develop further.

Bold move from Acala: EVM support coming!

The Acala team recently announced support for EVM-based smart contracts in their parachain. In short, this means that smart contracts that run on Ethereum can be run on their parachain. As they are targetting DeFi use case, I think that’s a great way to garner adoption. It’s also a bold strategy as I will outline below.
 
Some background on the Acala team
The team is actually composed to two teams who were already building for the Polkadot ecosystem. Those teams are PolkaWallet and Laminar. The latter focus on runtime engineering (“building chains”), while PolkaWallet is a mobile-first wallet for Polkadot (and Kusama).
These teams, both as separate entities and together as Acala, applied for grants in the Web3 Foundation grant program Each application was successful too. I know this since I prepared their contracts. 😉
In my dealings with them they were always professional and honest, plus their enthusiasm and dedication to Polkadot is unsurpassed.
 
What is Acala?
In their own words:  
“A decentralized stablecoin platform powering cross-blockchain open finance applications.” (Source)
The team are aiming to be the “decentralized financial hub of Polkadot” with “a suite of financial primitives: a multi-collateralized stablecoin backed by cross-chain assets like Bitcoin, a trustless staking derivative, and a decentralized exchange.” (Source)
Add in wallet support and you have a very compelling package that should entice both builders and users to the project. Merely building a blockchain doesn’t guarantee wallet support from day one, nor does it guarantee developers will want to build for it, but this is where Acala is making great headway to overcome those challenges.
For users, having access to a stablecoin is a big must and is something that I was personally wrong about. I didn’t think they would be so useful (+1 XP for me). Moreover, I suspect there could be a governance token coming too, one which is also the fuel for the contracts. I can see these features intertwining into some interesting token economics.
 
A bold strategy
A strong team announcing support for EVM-flavoured smart contracts is great for Polkadot, but I think it may ruffle a few feathers with other teams who are also planning to offer EVM compatibility. This is a bold move, but one that makes sense. Being able to attract DeFi developers to Polkadot is easier if there is a nice migration path from Ethereum to Polkadot.
It feels like a competitive move as EVM-compatible parachains will have an overlap in target audience. This is one of the interesting aspects of the blockchain space: you have open-source software and a general design principle of interconnectivity such that collaboration is highly encouraged, yet there is a limited number of developers. Acala is collaboratively in the sense that it should offer a stablecoin.
That said, there is some natural differentiation between the projects too. Should DeFi projects naturally adopt Acala, then I see this as an opportunity for non-DeFi projects to migrate to the other parachains (e.g. Plasm and Moonbeam). Ultimately, that may not be such a bad thing. Less projects on the same chain (“shard”) means less congestion.
The launching of the new parachains is something to watch closely over the next year or so; however, that is the subject of a future blog!
 
Acala Tokens
At the moment Acala are not selling any tokens to the public. If you see anything listed on Uniswap or elsewhere in the Ethereum ecosystem (e.g. as an ERC-20) then be very skeptical.
There has been some private sales to professional investors, but nothing public. There is no published date for a token sale, so currently there is no known way for small investors to get involved. Although I believe it could happen before launch. The team have a roadmap on their website which suggests a potential parachain launch of Q3 2020, but I do fear that timeline might slip.
Personally, I’d really like to buy some but as a non-professional investor of only modest means I will be waiting like everyone else in the community. While I believe Acala is a strong team I think everyone should do their own research and make up their own mind.

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Tools, Infrastructure & Documentation

Syscoin Bridge

Mainnet Demonstration of Syscoin Bridge with the Basic Attention Token ERC-20
A two-way blockchain interoperability system that uses Simple Payment Verification to enable:
  • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum
  • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

HOWTO: Setup an Agent
Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Mainnet: https://sys1.bcfn.ca (Blockbook)
Testnet: https://explorer-testnet.blockchainfoundry.co

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

I lost $1,200 in 100 seconds

A few days ago, a hacker got my mnemonic and stole $1,200 in ethereum from my Metamask wallet in under 100 seconds. The hackers were using a bot to scan for the mnemonic phrases across GitHub, and I accidentally left it in my code on a GitHub repo while I was sending to a Hack Money hack-at-hon. Although there are some coins and tokens left, the bot will siphon any ethereum I have to prevent me from moving my coins, and/or outmatch my attempts by supplying more gas.
I just want you all to be aware to NEVER have a digital copy of your mnemonic or private key . Especially not online.
If you are using metamask, randomly generate private keys for new accounts not associated with any mnemonics, and imported onto metamask
 web3.eth.createAccount() 
My compromised address: https://etherscan.io/address/0x1b3e1786c3f8524ca0f3175b0b37bcc1bee5a6d5
There is still $600 supposedly that's locked in Compound DeFi protocol and if anyone is interested in helping solve this, here is a suggestion someone made for me who we are seeking ways to solve this:
https://ethereum.stackexchange.com/questions/83718/how-to-retrieve-erc20-from-a-hacked-address-monitored-by-a-bot
I was foolish and this mistake was costly, but I know how to be extra secure when dealing in crypto. I was very upset and scared at first, but I can't dwell on it and I'll move on. No need to stress over thousands when I can focus on making millions.

Ethereum on ARM. New Eth2.0 Raspberry pi 4 image for automatically joining Prylabs Onyx Eth2.0 testnet. Step-by-step guide for installing and activating a validator.

TL;DR: Flash your Raspberry Pi 4, plug in an ethernet cable, connect the SSD disk and power up the device to join the Eth2.0 Onyx testnet.
The image takes care of all the necessary steps to join the Eth2.0 Onyx testnet [1], from setting up the environment and formatting the SSD disk to installing and running the Ethereum Eth1.0 and Eth2.0 clients as well as starting the blockchains synchronization (for both Geth Eth1.0 Goerli [2] and Prysm [3] Eth2.0 Beacon Chain).
You will only need to create a validator account, send the deposit of 32 Goerli ETH to the Onyx contract and start the validator systemd service.
MAIN FEATURES
SOFTWARE INCLUDED

INSTALLATION GUIDE AND USAGE

RECOMMENDED HARDWARE AND SETUP
STORAGE
You will need and SSD to run the Ethereum clients (without an SSD drive there’s absolutely no chance of syncing the Ethereum blockchain). There are 2 options:
In both cases, avoid getting low quality SSD disks as it is a key component of you node and it can drastically affect the performance (and sync times). Keep in mind that you need to plug the disk to an USB 3.0 port (in blue).
IMAGE DOWNLOAD AND INSTALLATION
1.- Download the image:
http://www.ethraspbian.com/downloads/ubuntu-20.04-preinstalled-server-arm64+raspi-eth2-onyx.img.zip
SHA256 13bc7ac4de6e18093b99213511791b2a24b659727b22a8a8d44f583e73a507cc
2.- Flash the image
Insert the microSD in your Desktop / Laptop and download the file:
Note: If you are not comfortable with command line or if you are running Windows, you can use Etcher [8]
Open a terminal and check your MicroSD device name running:
sudo fdisk -l 
You should see a device named mmcblk0 or sdd. Unzip and flash the image:
unzip ubuntu-20.04-preinstalled-server-arm64+raspi-eth2-onyx.img.zip sudo dd bs=1M if=ubuntu-20.04-preinstalled-server-arm64+raspi.img of=/dev/mmcblk0 conv=fdatasync status=progress 
3.- Insert de MicroSD into the Raspberry Pi 4. Connect an Ethernet cable and attach the USB SSD disk (make sure you are using a blue port).
4.- Power on the device
The Ubuntu OS will boot up in less than one minute but you will need to wait approximately 7 minutes in order to allow the script to perform the necessary tasks to join the Onyx testnet (it will reboot again)
5.- Log in
You can log in through SSH or using the console (if you have a monitor and keyboard attached)
User: ethereum Password: ethereum 
You will be prompted to change the password on first login, so you will need to log in twice.
6.- Forward 30303 and 13000 ports in your router (both UDP and TCP). If you don’t know how to do this, google “port forwarding” followed by your router model.
7.- Getting console output
You can see what’s happening in the background by typing:
sudo tail -f /valog/syslog 
7.- Grafana Dashboards
There are 2 Grafana dashboards to monitor the node (see section “Grafana Dashboards below”.
See [9]

The Onyx Eth2.0 testnet

Onyx is an Eth2.0 testnet created by Prylabs according to the latest official specification for Eth2.0, the v0.12.1 [10] release (which is aimed to be the final).
In order to run an Onyx Eth 2.0 node you will need 3 components:
The image takes care of the Eth1.0 Geth and Eth2.0 Beacon Chain configurations and syncs. So, once flashed (and after a first reboot), Geth (Eth1.0 client) starts syncing the Goerli testnet and the Beacon Chain (Eth2.0 client) gets activated through the Prysm client, both as systemd services.
When the Goerli testnet sync is completed, the Beacon Chain starts syncing. Both chains are necessary as the validator needs to communicate with them (as explained below).
Activating the validator
Once Goerli and the Beacon chain are in sync you have just one task left, configure the Validator for enabling the staking process.
The image provides the Prysm validator client for running the staking process. With this validator, you will create an account with 2 keys (public and private) and get an HEX string that needs to be sent to the Eth 1.0 blockchain as data through a 32 ETH transaction.
The Beacon Chain (which is connected to the Eth1 chain) will detect this deposit (which includes the validator public key) and the Validator will be activated.
So, let’s get started. Geth Goerli testnet and the Beacon Chain are already syncing in the background. Goerli will sync in about 1 hour and the Beacon Chain in about 2 hours (so this will take 3 hours overall).
The easiest way to enable a Prysm validator is to use the Prylabs web portal to get Goerli ETH (testnet ETH) and follow their instructions:
https://prylabs.net/participate
Let’s break this down:
Step 1) Get Prysm
Nothing to do here. Prysm is already installed.
Step 2) Get GöETH — Test ETH
We need 32 ETH to stake (it is fake ETH as this is a tesnet). Prylabs created a faucet with a great UI so you can easily get 32.5 Goerli ETH.
You will need a web3 provider to use the faucet. Install Metamask browser extension (if you don’t have it running yet). Create an account and set the network to “Goerli test network” (on the top of the Metamask screen). Now, click once in “Metamask” and then click “Need GoETH?” button. Confirm the transaction.
Once funded, you will see something like this:
You are 0x0b2eFdbFB8EcaF7F4eCF6853cbd5eaD86510d63C and you have 32.5 GöETH. 
Step 3). Generate a validator public / private key
Go to your Raspberry Pi console and run the following command (make sure you are logged in with your ethereum user):
validator accounts create 
Press return to confirm the default path
Enter a password twice (you will need it later to run the validator so write it down and be careful). Once finished, your account will be created (under the /home/ethereum/.eth2validators directory) containing, among other info, your validator keys. Additionally you will get the deposit data as follows (this is an example):
========================Deposit Data======================= 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 =================================================================== ***Enter the above deposit data into step 3 on https://prylabs.net/participate*** 
Copy this data (just the hexadecimal part, from 0x to the last number), go back to step 3 of Prylabs website and paste it into the field “Your validator deposit data”.
Step 4) Start your beacon chain & validator clients
Beacon chain is already running in the background so let’s configure the validator. Just edit the /etc/ethereum/prysm-validator.conf file and replace “changeme” string with your password (you can use nano or vim editors). Now run:
sudo systemctl enable prysm-validator && sudo systemctl start prysm-validator 
Check if everything went right by running:
sudo systemctl status prysm-validator 
Step 5) Send a validator deposit
We are almost there. Just click the “Make deposit” button and confirm the transaction.
Done!
Now you need to wait for the validator to get activated. In time, the beacon chain will detect the 32 ETH deposit (which contains the validator public key) and the system will put your validator in queue. These are the validator status that you will see during the activation process:

Grafana Dashboards

We configured 2 Grafana Dashboards to let users monitor both Eth1.0 and Eth2.0 progress. To access the dashboards just open your browser and type your Raspberry IP followed by the 3000 port:
http://replace_with_your_IP:3000 user: admin passwd: ethereum 
There are 3 dashboards available:
Lot of info here. You can see for example if Geth is in sync by checking (in the Blockchain section) if Headers, Receipts and Blocks are aligned or easily find the validator status.

Whats's next

We are planning a new release for a multi testnet Eth2.0 network including Prysm, Teku and Lighthouse client (and hopefully Nimbus).

In response to the current panic, some governments are starting to police free speech---this is unacceptable. Introducing SmokeSignal: Free Speech at the Protocol Level.

The COVID-19 panic is being used to encroach on free speech.
A quick google search is instructive. China is, of course, leading the charge in censoring dissenting views, and other Southeast Asian countries are following suit. The UK is heading down the same road, and Iran is arresting independent, "critical" reporting on the virus.
This is a serious problem.
If you have a hunch that somehow crypto should be able to protect us from this danger, you're right: Ethereum has already facilitated bypassing such censorship in China. As Forbes reports, the Chinese government has been censoring an article discussing various aspects of the COVID-19 outbreak--but it is now safely stored directly on Ethereum.
However, accessing this data is not simple, and posting it in the first place surely required obscure knowledge of Ethereum's inner workings and lots of trial-and-error.
SmokeSignal elmininates this difficulty, exposing unstoppably free speech to the end-user.
The conversation has already started. (If you can't follow .eth links, use our non-ENS mirror.)
Any SmokeSignal message can be read by anyone in a single click. This can be a .eth permalink or a non-ENS mirror link.
If you have a web3 wallet like MetaMask, ETH for gas, and DAI for burning, you can create your own SmokeSignal message. Once mined, you'll get a permalink like this one (non-ENS mirror).
Feel free to burn a tiny amount of DAI for now, but as SmokeSignal gets more use, interfaces like ours will begin to filter out low-burn messages. By burning more DAI, an author can signal a higher level of seriousness and expect more visibility.
It's high time for crypto to make moves on the global stage, and the clumsy failures of governments during this crisis have left the stage wide open.
SmokeSignal is one such move. Join the conversation (non-ENS mirror), and let's coordinate the next.
