Hermes: Low Tail-Latency Via Prefix Consensus

Alejandro Ranchal-Pedrosa, Dakai Kang, Neil Giridharan +3

Leader-based BFT protocols finalize through their leaders: a view whose leader is crashed or slow finalizes nothing, and the timeout that ends it admits no good setting. A conserva…

SafarDB: FPGA-Accelerated Distributed Transactions via Replicated Data Types

Javad Saberlatibari, Prithviraj Yuvaraj, Mohsen Lesani +2

Data replication is a critical aspect of data center design, as it ensures high availability, scalability, and fault tolerance. However, replicas need to be coordinated to maintain…

HYDRA: Breaking the Global Ordering Barrier in Multi-BFT Consensus

Hanzheng Lyu, Shaokang Xie, Jianyu Niu +5

Multi-Byzantine Fault Tolerant (Multi-BFT) consensus, which runs multiple BFT instances in parallel, has recently emerged as a promising approach to overcome the leader bottleneck…

Orthrus: Accelerating Multi-BFT Consensus through Concurrent Partial Ordering of Transactions (Extended Version)

Hanzheng Lyu, Shaokang Xie, Jianyu Niu +4

Multi-Byzantine Fault Tolerant (Multi-BFT) consensus allows multiple consensus instances to run in parallel, resolving the leader bottleneck problem inherent in classic BFT consens…
