I have a LocalCrypto.sol library (i.e. all in solidity) that supports El Gamal Encryption, One out of Two ZKP (i.e. either yes or no is encrypted), Pederson Commitments, Inequality proof (i.e. two commitments DO NOT commit to the same data), Equality proofs (i.e. two commitments DO commit to the same data), Discrete log equality proofs, and publicly verifiable secret sharing. I’m currently organising the code for public release (let others experiment with cryptography on the blockchain) – i’d like to present the library, its capability, some projects I have used it in and how people can start using it today.
