Strengthened Fault Tolerance in Byzantine Fault Tolerant Replication
Zhuolun Xiang, Dahlia Malkhi, Kartik Nayak +1
Byzantine fault tolerant (BFT) state machine replication (SMR) is an important building block for constructing permissioned blockchain systems. In contrast to Nakamoto Consensus wh…
Efficient Cross-Shard Transaction Execution in Sharded Blockchains
Sourav Das, Vinith Krishnan, Ling Ren
Sharding is a promising blockchain scaling solution. But it currently suffers from high latency and low throughput when it comes to cross-shard transactions, i.e., transactions tha…
Optimal Communication Complexity of Authenticated Byzantine Agreement
Atsuki Momose, Ling Ren
Byzantine Agreement (BA) is one of the most fundamental problems in distributed computing, and its communication complexity is an important efficiency metric. It is well known that…
Byzantine Agreement, Broadcast and State Machine Replication with Near-optimal Good-case Latency
Ittai Abraham, Kartik Nayak, Ling Ren +1
This paper investigates the problem \textit{good-case latency} of Byzantine agreement, broadcast and state machine replication in the synchronous authenticated setting. The good-ca…
Improved Extension Protocols for Byzantine Broadcast and Agreement
Kartik Nayak, Ling Ren, Elaine Shi +2
Byzantine broadcast (BB) and Byzantine agreement (BA) are two most fundamental problems and essential building blocks in distributed computing, and improving their efficiency is of…
Flexible Byzantine Fault Tolerance
Dahlia Malkhi, Kartik Nayak, Ling Ren
This paper introduces Flexible BFT, a new approach for BFT consensus solution design revolving around two pillars, stronger resilience and diversity. The first pillar, stronger res…
