Towards a High-velocity Permissioned Blockchain

分布式账本技术被认为是“游戏规则改变者”，因为它们允许分散的交易处理系统，交易费用最低，不需要相互信任的第三方。人们普遍认为，这些技术，尤其是经过许可的区块链，将从根本上改变从金融、房地产到能源和交通等行业。然而，现有的区块链在吞吐量方面受到高度限制，在典型工作负载下实现的交易不超过1000次/秒。这极大地限制了它们的实际应用。因此，我们的总体目标是为高速区块链实现可扩展且可证明正确的共识协议，并将该协议集成到现有系统中，例如Hyperledger Fabric。我们的目标是实现事务吞吐量超过100万次/秒。

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.
