# A simple zero-knowledge proof project to verify ownership of a hash for a particular data

This project is a simple implementation of a zero-knowledge proof to verify ownership of a hash for a particular data. The proof is based on the Poseidon hash function.

We can prove that we know the original data for the given hash without revealing it.

The proof is a proof of knowledge of a hash for a particular data. The prover proves that he knows a hash for a particular data without revealing the data itself. The verifier verifies that the prover knows a hash for a particular data.

The proof is based on the Poseidon hash function
