Distributed key generation (DKG) is a classical distributed crypto primitive that has been extensively studied for small scale in house deployments. However, the recent surge of blockchain applications raises a qualitatively different challenge for DKG on a massive scale. The long standing cubic complexity stands as a clear barrier. In this talk, we will introduce our recent progress on DKG: theory-wise: we give the first DKG with sub-cubic complexity after many years of research on DKG; practice-wise, we design a practical DKG protocol that could be scale to the whole blockchain network that enable the first realization of all-hands checkpointing, which is instrumental for securing proof of stake blockchain against long range attacks.
