Tornado Cash with Halo2
This is the repo we’re going to look at: Tornado core.

How I Built an Anonymous Voting System on the Ethereum Blockchain Using Zero-Knowledge Proof
The method that I’m using is the same as what is used by Tornado Cash. Tornado Cash is a non-custodial Ethereum and ERC20 privacy solution based on zkSNARKs.

A beginner's intro to coding zero-knowledge proofs
Tornado Cash is a great learning resource on how to build a real-world zk-app with Circom circuits. I strongly recommend going through the 3-page-long white paper, as well as Gubsheep's breaking down Tornado Cash session from the 0xparc course, plus Porter's overview of the white paper.

Zero-Knowledge Proofs Using SnarkJS and Circom
This was my very short tutorial on using zk-SNARK in JavaScript. It’s not a full course, and you probably have many questions, but I hope I helped you to start your journey. Circom and snarkjs are well documented, and you can also learn a lot from existing projects like Tornado Cash.

Doubt about tornado cash MerkleTree implementation
This is the MerkleTree contract, and the problem is on lines 58 and 59, I cannot understand why would you need to veryfy that the hash of a number has to be less than FIELD_SIZE.

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.
What are some alternatives?
