Multi-Party Computation
A cryptographic technique letting multiple parties jointly compute a result without revealing their private inputs.
Multi-party computation (MPC) is a cryptographic technique that lets several parties jointly compute a result — such as signing a transaction — without any single party ever having access to another's complete private input.
Some wallets use MPC to split private key material across multiple parties, so no single party ever holds a complete private key, as an alternative approach to traditional multisig.
Examples
- An MPC wallet can require multiple parties to jointly participate in signing, without any one holding a full private key.
- MPC is one of several distinct technical approaches to distributing signing authority across multiple parties.
