摘　　要：以太坊是一种开源的支持智能合约的公共区块链,有更快的“出块”速度和更先进的奖励机制。Quorum是一种支持隐私交易和隐私合约的联盟链,相比于以太坊而言,Quorum提供了交易和智能合约私有化功能、多种共识机制以及具有更高的性能。Quorum作为一个新生区块链平台,有关其性能的研究还很少。本文研究了Quorum在不同工作负载和一致性算法下的吞吐量,并且通过一系列微观基准测试后,更进一步探讨了事务和智能合约参数对吞吐量的影响。Ethereum is an open-source public blockchain supporting smart contracts with faster "block out" and more advanced reward mechanism. Quorum is an alliance chain supporting privacy transactions and privacy contracts. Compared with Ethereum,Quorum provides transaction and smart contract privatization functions, multiple consensus mechanisms and higher performance. As a new blockchain platform, there is little research on the performance of Quorum. In order to obtain its accurate performance data,the throughput of Quorum under different workloads and consistency algorithms is studied. After a series of micro-benchmarks, the impact of transaction and smart contract parameters on throughput is further explored.
