Abstract

This paper presents Basil, the first transactional, leaderless Byzantine Fault Tolerant key-value store. Basil leverages ACID transactions to scalably implement the abstraction of a trusted shared log in the presence of Byzantine actors. Unlike traditional BFT approaches, Basil executes non-conflicting operations in parallel and commits transactions in a single round-trip during fault-free executions. Basil improves throughput over traditional BFT systems by four to five times, and is only four times slower than TAPIR, a non-Byzantine replicated system. Basil's novel recovery mechanism further minimizes the impact of failures: with 30% Byzantine clients, throughput drops by less than 25% in the worst-case.

Basil:用ACID(交易)分解BFT

本文介绍了Basil，第一个事务性的、无领导的拜占庭式容错键值存储。Basil利用ACID事务在拜占庭参与者存在的情况下可伸缩地实现可信共享日志的抽象。与传统的BFT方法不同，Basil并行执行无冲突的操作，并在无故障执行期间在单次往返中提交事务。Basil将传统BFT系统的吞吐量提高了4到5倍，仅比TAPIR慢4倍，TAPIR是一种非拜占庭式复制系统。Basil的新型恢复机制进一步减少了故障的影响:在30%的拜占庭客户端情况下，吞吐量在最坏情况下下降不到25%。
