What is MPC?

MPC stands for Multi-Party Computation. It is a cryptographic protocol that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. No individual party learns anything about the other parties' inputs except what can be inferred from the output of the function. It's commonly used in scenarios requiring data analysis or computation across multiple organizations without revealing sensitive data, such as secure data aggregation, private machine learning, and secure auctions.
