I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Overview

Poseidon Hash Function implementation in Solidity

GitHub issues

Description

Currently, the most widely-used Poseidon hash function for EVM is implemented in JS, and it is performant but it could be more unreadable. Also, if you write a smart contract in Solidity, it has to link the bytecode or call an external contract address for hash functions, which is inconvenient.

In the future, Poseidon hash might be implemented as a precompile contract in the Ethereum protocol (https://eips.ethereum.org/EIPS/eip-5988), so that people can call it with cheap gas. However, I think it would still be valuable to have a Poseidon Solidity implementation as a baseline for the performance benchmark.

How to use

npm install poseidon-sol: install

How to test

npm install
npx hardhat test

Other commands

npx hardhat compile
npx hardhat coverage
