Abstract

Encountering the problems of diverse sources, opaque information, and difficult collaboration among nodes in a smart factory supply chain, we proposed a traceability model based on blockchain consensus technology. It can realize accurate traceability, transparent transmission, and trusted storage of supply chain information. First, we proposed a blockchain-based smart factory supply chain traceability model (BCTMSSF). It makes the donation process open and transparent using a decentralized, traceable, and tamper-proof blockchain. Second, we proposed a verifiable delegated proof of stake (VDPoS) scheme to solve the problems of centralization and security. It integrates a dynamic random probability mechanism and fuse mechanism. Finally, we conducted experiments on a blockchain platform and verified the proposed model. The results revealed that our model can solve the problems of real-time, reliable, and transparent traceability of supply chain information, alleviate the problem of centralization, and improve security.

BCTMSSF：一种基于区块链共识的智能工厂供应链溯源方法

摘要

针对智能工厂供应链中来源多样、信息不透明、节点间协作困难的问题，我们提出了一种基于区块链共识技术的溯源模型。可以实现供应链信息的准确追溯、透明传输、可信存储。首先，我们提出了基于区块链的智能工厂供应链追溯模型（BCTMSSF）。它使用去中心化、可追踪、防篡改的区块链，使捐赠过程公开透明。其次，我们提出了可验证的委托权益证明（VDPoS）方案来解决中心化和安全性问题。它集成了动态随机概率机制和熔断机制。最后，我们在区块链平台上进行了实验并验证了所提出的模型。结果表明，我们的模型可以解决供应链信息实时、可靠、透明的追溯问题，缓解中心化问题，提高安全性。
