Explore a groundbreaking 12-minute conference talk from USENIX OSDI '24 that introduces Chop Chop, a revolutionary Byzantine Atomic Broadcast system. Discover how this innovative approach uses a novel authenticated memory pool to optimize ordering, authentication, and deduplication of messages, achieving near "line rate" performance even with small 8-byte messages. Learn about the concept of distillation, a new form of batching that enables fast authentication, deduplication, and ordering of messages through an interactive protocol involving brokers. Examine the impressive performance metrics of Chop Chop in a geo-distributed deployment, processing over 43 million messages per second with low latency. Compare its capabilities to state-of-the-art alternatives and explore practical applications in payment systems, auction houses, and gaming. Gain insights into the future of state machine replication and decentralized, secure universal computation.
