公平分片共识和紧凑片间通信协议测试数据

分片是一种通用方法，用于增强分布式系统的可扩展性。近年来，许多工作致力于通过分片来扩展区块链的共识机制。本课题致力于设计高效分片共识及链上链下协同方案，数据集“2022YFB2701700-高延展高性能拜占庭共识算法及系统设计理论与方法研究/2022YFB2701704-004/公平分片共识和紧凑片间通信协议测试数据-清华大学机房及云服务器”包含两个数据项：1）研究低延迟跨片交易处理协议的“低延迟跨片交易处理协议测试数据”数据，基于委员会抽样方法，设计了分片间的监督机制设计及证明方案Pando，在半同步环境中构建了一个极其高效、可扩展至1,000节点且自适应安全的分片共识协议，支撑了课题四指标4.1的结论；2）研究高延展分片共识机制的“高延展分片共识机制测试数据”数据，提出紧凑型片间通信方案，构建了不引入任何额外假设的分片共识Otter，支撑了课题四指标4.2的结论。

Sharding is a universal approach to enhancing the scalability of distributed systems. In recent years, numerous studies have focused on scaling blockchain consensus mechanisms via sharding. This research project focuses on designing efficient sharding-based consensus and on-chain/off-chain collaboration schemes. The dataset "2022YFB2701700-Research on High Extensibility and High Performance Byzantine Consensus Algorithm and System Design Theory and Methods/2022YFB2701704-004/Test Data for Fair Sharding Consensus and Compact Inter-shard Communication Protocol - Tsinghua University Computer Room and Cloud Server" contains two data items: 1) The "Low-latency Cross-shard Transaction Processing Protocol Test Data", which targets research on low-latency cross-shard transaction processing protocols. Based on the committee sampling method, we designed the inter-shard supervision mechanism and proof scheme Pando, and constructed an extremely efficient, scalable sharding consensus protocol that can support up to 1,000 nodes and features adaptive security in a semi-synchronous environment, which supports the conclusion of Indicator 4.1 of Task 4; 2) The "High Extensibility Sharding Consensus Mechanism Test Data", which targets research on high extensibility sharding consensus mechanisms. We proposed a compact inter-shard communication scheme and constructed the sharding consensus protocol Otter without introducing any additional assumptions, which supports the conclusion of Indicator 4.2 of Task 4.
