Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Create your own Uniswap DeFi Application๐ฆ! From scratch using Vyper & Python๐
๐ง 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.

Daily General Discussion - February 28, 2023
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.

Introducing AMM and Proof of Trade Protocol.
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.

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

What are some good open-source repositories that I can contribute to as a beginner blockchain developer?
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?

Can I Contribute Through Python?
You could try Vyper if you'd want to try developing smart contracts.

Ethereum Isn't Fun Anymore
> 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.

API to do trades on a DEX?
One more advice - try executing the swaps in javascript/nodejs (https://github.com/ethers-io/ethers.js/) or python (https://github.com/eth-brownie/brownie) first, can be easier to learn. Then move it into a smart contract.
-
Any web3.py learning platform like cryptozombies?
Check out ETH-Brownie first of all, you're going to love it if you're a Python guy. The docs are great.

Learning Vyper over Solidity
For someone coming from Python, Vyper would be easier to learn. There is some learning material to help you start, but for more advanced concepts it might be harder to find. And some of Ethereum tools (for security, for monitoring) are built for Solidity, but in the last couple of months some of them started to include more Vyper support. And to test your contracts, and a basis dev environnement for Vyper, Brownie (https://github.com/eth-brownie/brownie) might be the best choice, since it's Python based
