Today, Safeheron announced the open-sourcing of its C++ implementation of a Lindell 17 two-party MPC (2PC) threshold ECDSA protocol. Designed specifically for 2-of-n collaborative signature scenarios, this protocol offers higher efficiency and lower signature latency in a client-side + server-side architecture compared to general threshold schemes. This open-source implementation fully covers the key generation and signature process, natively supports standard elliptic curves such as secp256k1, and incorporates security hardening measures against known implementation-level attacks. Safeheron aims to uphold its "transparency equals security" philosophy through continuous open-sourcing, providing developers with representative code references and enriching the MPC technology ecosystem. The code is now available on GitHub.
