Decentralized Key Generation for Zama Mainnet Has Successfully Completed
Blog post from Zama
The Decentralized Key Generation (DKG) ceremony for the Zama mainnet successfully concluded, involving 13 independent parties who jointly executed an advanced cryptographic protocol to generate the public encryption key for the Zama Confidential Blockchain mainnet. This process ensured that the private key remained secret-shared among participants, preventing any single entity from accessing it fully. The MPC protocol, designed to maintain performance akin to non-decentralized Fully Homomorphic Encryption (FHE) systems, overcame challenges associated with decentralized key generation, such as participant dropouts or malicious actions, by achieving robustness against up to four offline or disruptive operators. This accomplishment marked the largest robust MPC protocol executed in a production environment, utilizing AWS Nitro Enclaves and Hardware Security Modules for enhanced security. The successful completion of the DKG is a significant step towards bringing FHE into production, with Zama poised to launch its mainnet shortly.
