Poseidon Hash over bn254 with Typescript

DeadDrop ZK App — A zero-knowledge proof system to verify encrypted messages without revealing them. Built with Circom, Groth16, and Poseidon hash. Proves that decryption of ciphertext with a private key matches a commitment. Ideal for anonymous message reveals.

A set of small, self-contained command-line programs in C.

Compact Rust implementation of the Poseidon hash over arkworks fields.

Three composable ZK bugs across circuit + Solidity integration: underconstrained commitment, dead Merkle public input, and unbound recipient. Foundry test suite + reference fixes.

zkMaze is a web3 maze game that leverages ZKPs to verify player moves without revealing the maze configuration.
