tpke

This repository is an experimental implementation of decentralized threshold encryption and decryption.

Architecture

• DKG - A decentralized key generation process where participants generate and share their local secret, to get a global public key for encryption and signature verification;
• TPKE - A use case where users encrypt something with global public key, and participants try to decrypt with their different pieces of secret;
• TSS - A use case where participants sign something with local secrets, and users verify the result with the global public key;
• DBFT - A use case that involves both TPKE and TSS to realize anti-MEV and true random numbers, locates in another repo.
