摘要:
区块链技术是一种基于公钥加密和 P2P 网络的分布式智能账本技术。其去中心化、去信任、信息透明等原生优点完美契合物流行业对数据不可篡改,信息永久可溯源的需求,且解决了流通环节多方共同参与情况下的信任问题。 但是,现有主流区块链系统在性能和安全性上难以兼得,区块链系统中的各项关键技术仍有待进一步改进。 针对国内物流快递行业当前发展的痛点,文中提出了一个基于联盟区块链的物流业信息平台系统 LIP-Chain。 该系统解决了传统信息系统中心机构权利过大、信息难以溯源等问题,重新定义了物流信息的交易和存储方式。 对系统设计的关键问题,如访问控制及身份管理、共识算法、安全与隐私保护等进行了详细分析,并搭建了原型系统进行仿真实验。 实验结果表明,LIP-Chain 不仅吸收了上述区块链技术的特性,且具有较强的可扩展性,能够支撑包含上百完整节点以及上千客户端的区块链网络;资源占用量低,内存占用不足 100 M,CPU、网络 IO 等开销远低于一般移动设备的硬件配置;数据吞吐量较大,可达到每秒几百至几千笔交易。
Abstract:
Blockchain is an intelligent distributed ledger technology (DLT) based on public key encryption and P2P networks. Its original advantages,such as decentralization, elimination of trust,and information transparency have perfectly meet the needs of the logistics industry for data not to be tampered with and information to be traceable forever,and solved the problem of trust when multiple parties participate in the circulation. However,the current mainstream blockchain system is difficult to have both performance and security,and the key technologies in the blockchain system still need to be further improved. Aiming at the pain points of the current development of domestic logistics express industry,we propose a logistics information platform system LIP-Chain based on permissioned blockchain. Unlike traditional information systems,LIP-Chain redefines the way to exchange and store logistics data,and solves the centralization and traceability issues perfectly. Furthermore,the key issues are discussed in detail,such as access control and identity management,consensus algorithm,security and privacy protection methods. Finally,the simulation shows that LIP-Chain not only maintains the above merit of blockchain,but also has strong scalability,which can support the blockchain network consisting of hundreds of complete nodes and thousands of clients. With low resource consumption,less than 100 M of memory,CPU,network IO and other costs are much lower than the hardware configuration of general mobile devices. Data throughput is large and can achieve hundreds to thousands of transactions per second.
