Hello, I am a blockchain engineer with several years of experience. Anyone interested in getting into the world of blockchain development can book a meeting with me to AMA 1on1 for 15 minutes
My current work involves zero-knowledge proofs technology, quite an interesting thing and very similar to writing VHDL code. The language we use for zero-knowledge proofs is circom, compiler here: https://github.com/iden3/circom and the code written in circom is called circuits which is very similar to coding for FPGA platforms.

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.
