WebJun 21, 2024 · Scalable and Probabilistic Leaderless BFT Consensus through Metastability. This paper introduces a family of leaderless Byzantine fault tolerance protocols, built around a metastable mechanism via network subsampling. These protocols provide a strong probabilistic safety guarantee in the presence of Byzantine adversaries while their … Webof scalable BFT protocol designs. We comprehensively discuss the different ideas on an abstract level and pinpoint the design space from which these BFT protocols originate. D. Outline In §II, we first give an overview of the basics of BFT protocols. Next, we present our methodology in §III, which is based on a systematic literature search.
