【Abstract】Regular safety inspection is critical to reduce safety risk in industry. Applying the consortium blockchain technology to safety inspection can ensure the effectiveness of the inspection process and tracing of problems. However, there are two major issues when using conventional consortium blockchain. It is challenging to guarantee the authenticity of the retrieved data source, and meanwhile, achieving a balance between performance and security is not easy. Hence, this article proposes a blockchain-based performance-security balanced safety inspection framework (PSB-SIF), in which a safety inspection box is designed to ensure the authenticity of the inspector's identity while inspection logic is executed automatically via smart contracts. In addition, this article also proposes a novel credit scoring-based Byzantine fault-tolerant (BFT) consensus algorithm, named safety inspection BFT consensus algorithm (SIBFT), which is used to balance the performance and security of consensus network in a safety inspection. We evaluate the proposed approach by comparing with the solutions using RAFT, Practical BFT (PBFT), and SIBFT consensus algorithms in terms of throughput, transaction latency, scalability, and security of PSB-SIF. The evaluation results show that PSB-SIF is efficient for all these quality metrics.

【标题】使用性能安全平衡区块链的可信赖安全检查框架
【摘要】定期安全检查对于降低行业安全风险至关重要。将联盟区块链技术应用于安全检查，可以保证检查过程的有效性和问题的追溯。然而，在使用传统的联盟区块链时存在两个主要问题。保证检索到的数据源的真实性具有挑战性，同时在性能和安全性之间取得平衡也并非易事。因此，本文提出了一种基于区块链的性能-安全平衡的安全检查框架（PSB-SIF），其中设计了一个安全检查箱来确保检查员身份的真实性，同时通过智能合约自动执行检查逻辑。此外，本文还提出了一种新颖的基于信用评分的拜占庭容错（BFT）共识算法，命名为安全检查BFT共识算法（SIBFT），用于在安全检查中平衡共识网络的性能和安全性。我们通过在 PSB-SIF 的吞吐量、事务延迟、可扩展性和安全性方面与使用 RAFT、Practical BFT (PBFT) 和 SIBFT 共识算法的解决方案进行比较来评估所提出的方法。评估结果表明，PSB-SIF 对于所有这些质量指标都是有效的。
