Safeheron open-source Lindell 17-party MPC protocol to reduce multi-signature latency

【Crypto World】Safeheron recently announced the open source release of a C+±based implementation of the Lindell 17 two-party MPC (2PC) protocol, a specialized optimization for 2-of-n multi-signature scenarios.

Compared to general threshold signature schemes, this implementation performs exceptionally well under the classic “client + server” architecture—faster signing speeds and lower interaction latency. This is particularly significant for wallets or transaction scenarios requiring high-frequency confirmations.

From a technical perspective, the solution fully covers the entire key generation and signing process, natively supports standard elliptic curves like secp256k1, and is fully compatible with the Bitcoin ecosystem. More importantly, the team proactively incorporated security hardening measures into the engineering implementation, defending against known implementation-layer attacks.

Safeheron has uploaded this code to GitHub with a straightforward philosophy—transparency is the best form of security verification. Through open sourcing, it provides developers with reference cases and promotes the maturity of the entire MPC technology ecosystem. This is a valuable learning resource for teams interested in researching or deploying multi-party computation signing schemes.
