Explore the foundations of Dynamic Byzantine Fault Tolerance (BFT) in this 20-minute IEEE conference talk. Delve into the concepts of static BFT, dynamic membership, and related works before examining the definitions and challenges associated with dynamic BFT. Gain insights into concrete constructions, including an overview and a focus on the Dyno protocol and its variants. Analyze the evaluation of these constructions and draw conclusions about the future of dynamic BFT in distributed systems.
