Multi-Party Computation

Definition ∞ Multi-Party Computation (MPC) is a cryptographic protocol enabling multiple parties to jointly compute a function over their private inputs without disclosing those inputs to each other. This technology ensures data privacy while allowing collaborative data processing or decision-making. MPC allows for secure operations where individual data remains confidential, even from the other participants in the computation. It forms a fundamental building block for advanced privacy-preserving applications in digital systems.
Context ∞ In the cryptocurrency and blockchain domain, Multi-Party Computation is gaining traction for enhancing security and privacy in various applications. It is used for secure key management, threshold signatures and confidential transactions, reducing reliance on single points of failure. News often highlights MPC’s role in improving the security of digital asset custodianship and decentralized exchanges. This technology is critical for advancing the utility and adoption of privacy-centric blockchain solutions.
