MANTA: Unlocking DAG Flexibility in Asynchronous BFT
Mohan Yu, Chenlin Wu, Jianyu Niu +2
DAG-based BFT protocols marked a shift in consensus design by replacing single-leader proposal paths with concurrent block proposals linked through a shared graph, where references…
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…
Chimera: Protocol-Aware Recovery for Confidential BFT Consensus
Tong Liu, Xiaoqing Wen, Ziwei Zhou +4
Trusted Execution Environments (TEEs) have enabled confidential Byzantine Fault-Tolerant (BFT) consensus systems with confidentiality and improved scalability. However, TEEs do not…
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…
