Multi-party computation, or MPC, is a type of cryptographic protocol that allows a group of parties to compute a function on their inputs, without revealing their inputs to each other. This allows the parties to securely compute a function on sensitive data, without revealing the data itself. MPC protocols are used in many different applications, including secure communication, privacy-preserving machine learning, and secure multiparty computation of smart contracts or a transaction signature. MPC protocols typically involve a mix of cryptographic techniques, such as secret sharing and zero-knowledge proofs, to enable secure computation without revealing the inputs to the other parties. MPC has the potential to revolutionize the way that sensitive information is processed and used, by enabling secure computation on sensitive data without revealing it to the parties involved.
