besu VS vyper

Daily Goerli: I've been testing this PR for besu for the past several days, and the stability of nimbus-besu has improved substantially. Looking forward to it getting merged into main.

Check out the Layered TX pool PR for more details and benchmarks - https://github.com/hyperledger/besu/pull/5290

you can check this spreadsheet for a comparison https://github.com/hyperledger/besu/files/11137473/Layered.Transaction.Pool.metrics.ods

Yes, it's gotten better. I don't recommend pairing with nimbus until this issue gets fixed or prysm until something is done to reduce the amount of time it takes to recover from being offline for a day or more.

Daily Goerli: On Friday, I reported a RocksDB issue that was causing besu to error and exit immediately. The bad commit has been identified and a fix has been issued. lodestar-nethermind somehow ended up on an invalid fork which isn't resolved by restarting either client. Waiting to see how each client team responds and if they need more info, but might need to do a resync.

Now running into this error on my freshly synced Besu 23.1.0. 😔️

🚧 To do this, we need to create a mocks/ folder inside the contracts/ folder, and within it, create an Token.vy file. You can add the code from the following link to this file: Vyper ERC20 Token.

Patrick Collins, CEO of uh "Chain Accel / Cyfrin / Alpha Chain" (video, kinda) gave a different kind of talk than most, focusing on the differences between Solidity and Vyper in terms of their compilation strategies and optimizations. Maybe it's just nice to see a talk that's just a collection of technical fun facts rather than trying to shill me on their product. I'll admit I didn't realize people still used Vyper, but I'm not a smart contract dev and their github is still active at least. An interesting look into compiled EVM bytecode/opcode.

Feel stuck? Take a look at the Vyperlang Official Implemenation

Swap.Dance is an Ethereum dApp which allows anyone to swap ERC20 tokens and ETH with low slippage. Proof of Trade concept provides a new type of staking mechanism for LP providers. Smart contracts were deployed on Vyper v0.3.3 and are immutable and not upgradeable. Github.

Vyper - Pythonic Smart Contract Language for the EVM

Create a new file named SampleToken.vy in contracts/ directory. Then implement a smart contract while referring to the Vyper ERC20 example.

How about vyper? https://github.com/vyperlang/vyper

1) Research the community that surrounds the project and see how the general ecosystem works. Normally, on Discord or Telegram you can start talking with devs and get a deeper understanding of the project. 2) Try to narrow down, which kind of project you want to contribute. A DEX / DeFi project like UniSwap or SushiSwap or yarn.finance? Or more like a tool like MetaMask? Or even, more like an Ethereum client like Besu, Geth or Erigon? Or even, Vyper or Solidity?

You could try Vyper if you'd want to try developing smart contracts.

> I need a hero, and by that, I mean that I need a usable methodology for building scaleable decentralized apps. Yes, you've heard that right. We don't need more "Ethereum killers" that can do 10x more tx/s than Ethereum. Those are useless.

Having worked on large Ethereum smart contracts (running an auction on chain) over two years, I fully agree with this. Ethereum needs better smart contract languages, better compilers and better dev tooling.

As our smart contract written in Vyper (for ease of auditing) grew larger and larger, eventually we failed to deploy on the testnet, and closer inspection reveal that the compiler was blowing up code size which I had to patch[0]. Down the line upstream further increased gas costs by emitting code that zeroed out every member of an array (note the EVM already has all memory set to 0). To support efficient insertion/deletion of bids we had to handroll a skip list on the blockchain(!), because there are no Vyper libraries.

On the language development side, things don't look too pretty either, I ended up having to write an EVM assembler from scratch[1], but deeper still are problems such as a lack of a separate call stack in EVM, so procedure calls always end up clunky and implementation-dependent.

Perhaps eWASM will alleviate some of these concerns. But until then, the entire dev process for writing smart contracts is painful.
