DispersedLedger - High-Throughput Byzantine Consensus on Variable Bandwidth Networks

Explore a groundbreaking presentation from NSDI '22 on DispersedLedger, an innovative asynchronous Byzantine fault tolerant (BFT) consensus protocol designed for high-throughput performance in variable bandwidth networks. Delve into the research conducted by experts from MIT CSAIL, University of Washington, and Stanford University as they introduce a novel approach to blockchain technology. Learn how DispersedLedger enables nodes to propose, order, and agree on transaction blocks without downloading their full content, effectively decoupling bandwidth-intensive block downloads and allowing nodes to progress at individual paces. Discover the protocol's impressive performance improvements, including 2x better throughput and 74% reduced latency compared to the state-of-the-art HoneyBadger protocol, as demonstrated in geo-distributed wide-area deployments across the Internet. Gain insights into the potential impact of this technology on large-scale BFT consensus protocol deployments over wide area networks.
