The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Tornado Cash with Halo2
Circuits were written with Circom and that’s what we’re going to change. We’ll rewrite those circuits with Halo2, the PSE implementation (the KZG one, i’ll tell you more about it in the next section).

A beginner's intro to coding zero-knowledge proofs
When starting with Halo2, keep in mind that there are two flavors of the framework out there: the vanilla one maintained by ZCash, and the fork by Ethereum's Privacy and Scaling Explorations team which uses a different polynomial commitment (KZG instead of IPA) that's more friendly for Ethereum.

A beginner's intro to coding zero-knowledge proofs
I found Circom to be the best language to start learning ZKPs, as suggested by CyberPorter. To me, Circom has the ideal level of abstraction for learning: not too high level that it abstracts away some of the quirks of ZKP, and not too low level that you get bogged down in annoying details. It also has been around for quite some time (modulo how new everything ZK is!), so you can find more documentation and samples, as well as the awesome Circom workshops from 0xparc. Last but not least, there is circomlib, a library of common building blocks for Circom.

Zero-Knowledge Proofs Using SnarkJS and Circom
The other thing we need is the circomlib. Circomlib is a programming library with many useful predefined circuits. So, create an empty project, and install circomlib using this code:
