Secure Computation

Definition ∞ Secure Computation refers to cryptographic techniques that allow multiple parties to jointly compute a function over their inputs while keeping those inputs private. This ensures that no party learns anything about the other parties’ inputs beyond what can be inferred from the output of the computation itself. It is foundational for privacy-preserving applications in decentralized systems.
Context ∞ Secure computation techniques, such as multi-party computation (MPC) and homomorphic encryption, are gaining traction for their ability to enable private data analysis and secure transactions on blockchains. News frequently highlights new applications of these technologies in areas like decentralized identity, private voting, and confidential DeFi transactions. Ongoing research aims to improve the performance and scalability of these cryptographic primitives for broader adoption.
