Breaking Fault Lines: Unifying TEE-Assisted BFT Consensus in Partially Trusted Worlds
Xiaoqing Wen, Tong Liu, Jianyu Niu +4
This paper revisits TEE-assisted BFT under a universal partial-TEE model, where an arbitrary subset of replicas execute inside TEEs while the remaining replicas operate without har…
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…
Unraveling Responsiveness of Chained BFT Consensus with Network Delay
Yining Tang, Mohan Yu, Qihang Luo +4
With the advancement of blockchain technology, chained Byzantine Fault Tolerant (BFT) protocols have been increasingly adopted in practical systems, making their performance a cruc…
Ladon: High-Performance Multi-BFT Consensus via Dynamic Global Ordering (Extended Version)
Hanzheng Lyu, Shaokang Xie, Jianyu Niu +3
Multi-BFT consensus runs multiple leader-based consensus instances in parallel, circumventing the leader bottleneck of a single instance. However, it contains an Achilles' heel: th…
