摘要 现代供应链是一个复杂的系统,在全球经济一体化的环境下对不同行业起着重要的作用。供应链管理系统被设计于处理日益复杂的商品流动,并且提高其运营效率。它对于防止潜在的欺诈行为和保证贸易规范化也起着作用。目前,大多数公司都拥有自己的供应链管理IT系统。但是,这些孤立的系统很难协同工作,并且给高度分散的供应链系统提供一个全局视野。使用新兴的分布式账簿/区块链技术(一种特殊的分布式系统)来构建供应链管理系统为解决这些挑战提供了一个具有广阔前景的方向。然而分布式账簿技术本身常常会受到性能和对存储数据缺乏保护的制约。为了克服这些挑战,我们设计了基于分布式账本技术的供应链管理系统(CoC)。该系统采用新颖的两步式块构建机制,提高了区块链的性能。我们还设计了一个满足供应链管理要求的高效存储方案。这些技术也可以用于其他建立在分布式账簿技术之上的应用。

Abstract: Modern supply chain is a complex system and plays an important role for different sectors under the globalization economic integration background. Supply chain management system is proposed to handle the increasing complexity and improve the efficiency of flows of goods. It is also useful to prevent potential frauds and guarantee trade compliance. Currently, most companies maintain their own IT systems for supply chain management. However, it is hard for these isolated systems to work together and provide a global view of the status of the highly distributed supply chain system. Using emerging decentralized ledger/blockchain technology, which is a special type of distributed system in essence, to build supply chain management system is a promising direction to go. Decentralized ledger usually suffers from low performance and lack of capability to protect information stored on the ledger. To overcome these challenges, we propose CoC (supply chain on blockchain), a novel supply chain management system based on a hybrid decentralized ledger with a novel twostep block construction mechanism. We also design an efficient storage scheme and information protection method that satisfy requirements of supply chain management. These techniques can also be applied to other decentralized ledger based applications with requirements similar to supply chain management.
