Poseidon-solidity is an implementation of the Poseidon hash function in Solidity, optimized for use over the alt_bn128 curve. It provides a gas-efficient alternative to other Poseidon implementations, making it suitable for applications requiring zero-knowledge proofs or other cryptographic operations on the Ethereum blockchain. This library is designed for developers building smart contracts that need a secure and efficient hashing algorithm, particularly those working with zk-SNARKs or similar cryptographic protocols.
