ePrint Report: Asynchronous Consensus without Trusted Setup or Public-Key Cryptography

Sourav Das, Sisi Duan, Shengqi Liu, Atsuki Momose, Ling Ren, Victor Shoup

Byzantine consensus is a fundamental building block in distributed cryptographic problems. Despite decades of research, most existing asynchronous consensus protocols require a strong trusted setup and expensive public-key cryptography. In this paper, we study asynchronous Byzantine consensus protocols that do not rely on a trusted setup and do not use public-key cryptography such as digital signatures. We give …
