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.

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:

How to Implement a ZK rollup
The advantage of SMT over the general Merkle tree is that it not only allows us to provide an inclusion proof but also an exclusion proof. This means that we can prove that a tree does not contain a value for the given key. Thanks to this, we can prove any operation (insert, delete, update), which will be a very important property of our rollup. Fortunately, Circomlib (and CircomlibJS) includes an SMT implementation, so we do not need to implement this ourselves.
