Distributed ledger technologies have been recognized as 'game changers' because they permithighly-decentralized transaction-processing systems with minimal transaction fees and withoutthe need for a mutually trusted third-party. It is widely believed that these technologies, especiallypermissioned blockchains, will fundamentally alter industries ranging from finance and real-estateto energy and transportation. However, existing blockchains are highly limited in terms oftheir throughput, achieving no more than 1000 transactions/second for typical workloads. Thisgreatly limits their practical applicability. Hence, our broad goals are the implementation of ascalable and provably correct consensus protocol for high-velocity blockchains, and integrationof this protocol into an existing system, such as Hyperledger Fabric. Our goal is to achieve atransaction throughput exceeding 1 million transactions/s.

分布式分类账技术已被公认为“游戏规则的改变者”，因为它们允许以最低的交易费用和不需要相互信任的第三方的方式实现高度分散的交易处理系统。人们普遍认为，这些技术，特别是获准的区块链，将从根本上改变从金融和房地产到能源和交通的各种行业。然而，现有的区块链在吞吐量方面非常有限，对于典型的工作负载来说，实现的事务不超过1000笔/秒。这极大地限制了它们的实际适用性。因此，我们的广泛目标是为高速区块链实现可扩展和可证明正确的共识协议，并将该协议集成到现有系统中，如Hyperledger Fabric。我们的目标是交易吞吐量突破100万笔/S
