Guest post by Zhuolun Xiang In the previous post, we presented a summary of our good-case latency results for Byzantine broadcast and Byzantine fault tolerant state machine replication (BFT SMR), where the good case measures the latency to commit given that the leader/broadcaster is honest. In this post, we describe...| decentralizedthoughts.github.io
Guest post by Zhuolun Xiang State Machine Replication and Broadcast Many existing permission blockchains are built using Byzantine fault-tolerant state machine replication (BFT SMR), which ensures all honest replicas agree on the same sequence of client inputs. Most of the practical solutions for BFT SMR are based on the Primary-Backup...| decentralizedthoughts.github.io
Simplex is a partially synchronous Byzantine Fault Tolerant (BFT) protocol designed by Ben Chan and Rafael Pass in 2023. It is being incorporated by Commonware library and (with modifications) by Solana. It is a simple and clean protocol, especially for beginners, and Ben did a great job explaining it from...| decentralizedthoughts.github.io
