摘要

为利用区块链、智能合约和物联网等新技术的优势，提高供应链信息化水平，设计开发了基于区块链、智能合约和物联网的供应链原型系统。借助物联网中的二维码、RFID和NFC实现供应链各主体数据的自动化上传；利用区块链和智能合约，完整保存了整个供应链各主体的数据，保证了数据公开透明、可追溯且不可篡改，同时兼顾了隐私数据的加密保护；并针对不同用户提供了不同程度的数据查询功能。通过这些优化和改进，使供应链系统更加自动化、更加安全可信，便于监管溯源。

Abstract

In order to take the advantages of new technologies such as blockchain, smart contract and Internet of Things, and improve the informatization level of supply chain, a supply chain prototype system, which is based on blockchain, smart contract and Internet of Things, is developed. With the help of two-dimensional code, RFID and NFC in the Internet of Things, automatic uploading of the supply chain data is implemented. The system uses blockchain and smart contract to completely save the data of the whole supply chain, thus it ensures the data is transparent, traceable and cannot be tampered with. Meanwhile it takes protection of privacy data into account and provides data query functions at different levels for users. Through these improvements, the supply chain system is more automated, safer and more reliable, and makes traceability easy.

Key words： blockchain; smart contract; internet of things
