## Multi-Party Computation Security

Multi-party computation security is a cryptographic technique that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. In digital asset custody, it is used to split a private key into multiple shards held by different entities, so no single party ever has access to the full key.

This significantly reduces the risk of theft or loss, as an attacker would need to compromise multiple, geographically distributed systems simultaneously. It is a cornerstone of institutional-grade security for crypto-assets.

By removing single points of failure, MPC provides a more resilient alternative to traditional multi-signature wallets. Its adoption is a key factor in the increasing comfort level of large financial institutions holding digital assets.
