Safeheron has officially open-sourced its C++-based Lindell 17 MPC protocol.

Odaily Planet Daily reports that Saferon today announced 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 collaborative signature scenarios and offers higher efficiency and lower signature latency in a "user-side + server-side" architecture compared to general threshold solutions.

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