WebSep 29, 2024 · One of the foremost aspects in an MPC vs Multi-sig comparison, apart from security, would point towards compatibility. The bad news for multi-signature is that it supports only a few blockchain protocols. On the other hand, multiparty computation is completely blockchain agnostic and can work with almost any ledger.
WebSecure multiparty computation has been implemented in various well-known protocols.
