ZKMPC: Bring public auditability into MPC

Tue, Nov 12, 2024, 11:08 AM · 23:09

In multi-party computation (MPC), participants collaboratively compute without revealing private inputs. To secure MPC on a blockchain, preventing collusion is essential. We developed a "publicly auditable" version of SPDZ, a widely-used MPC protocol, that enables third-party verification through zero-knowledge proofs (ZKP) collaboratively generated by multiple parties. We will also demonstrate application examples, such as a Game Master-free werewolf game.
