Safeheron officially open-sources the Lindell 17 MPC protocol based on C++

According to Odaily, Safeheron announced today the open-sourcing of its Lindell 17 two-party MPC (2PC) threshold ECDSA protocol implemented in C++. This protocol is specifically designed for 2-of-n co-signing scenarios and, compared to general threshold schemes, offers higher efficiency and lower signing latency under the "client + server" architecture.

This open-source implementation fully covers the key generation and signing processes, natively supports standard elliptic curves such as secp256k1, and introduces security enhancements in the engineering implementation to defend against known implementation-level attacks. Safeheron aims to uphold the technical philosophy of "transparency is security" through continuous open-sourcing, providing developers with representative code references and enriching the MPC technology ecosystem. The code is now available on GitHub.
