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…
Cassandra: Consensus with Partial Progress via Robust Partitionable View Synchronization
Shaokang Xie, Dakai Kang, Junchao Chen +3
Replicated databases and permissioned blockchain systems rely on Byzantine Fault-Tolerant (BFT) consensus to maintain a globally consistent order of transactions across distributed…
Fides: Secure and Scalable Asynchronous DAG Consensus via Trusted Components
Shaokang Xie, Dakai Kang, Hanzheng Lyu +2
DAG-based BFT consensus has attracted growing interest in distributed data management systems for consistent replication in untrusted settings due to its high throughput and resili…
FairDAG: Consensus Fairness over Multi-Proposer Causal Design
Dakai Kang, Junchao Chen, Tien Tuan Anh Dinh +1
The rise of cryptocurrencies like Bitcoin and Ethereum has driven interest in blockchain database technology, with smart contracts enabling the growth of decentralized finance (DeF…
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…
