Byzantine Quorums and Hyperledger Fabric

This lecture covers the basics of Byzantine Fault Tolerance (BFT) and its application in Hyperledger Fabric. It discusses the challenges of achieving consensus in distributed systems, the concept of state-machine replication, and the evolution of blockchain technology from Bitcoin to Ethereum and Hyperledger Fabric. The lecture delves into the architecture of Hyperledger Fabric, the order-execute model, and the Mir-BFT protocol for total order broadcast. It also explores the performance evaluation of Mir-BFT in WAN settings and the key requirements for Hyperledger Fabric's design. The presentation concludes with insights on preventing transaction duplication, scalability, and the future prospects of Mir-BFT as a production-ready BFT library.
