Research on the Application of Product Identity Based on Blockchain Technology
基于区块链技术的产品身份证应用研究

摘要

产品身份证在防伪溯源、供应链管理等领域具有重要价值，但传统系统面临数据易篡改、信息孤岛、信任成本高 等困境。区块链技术以其去中心化、不可篡改、可追溯等特性，为产品身份证应用提供了新路径。区块链是一种按时 间顺序对数据区块进行排列，以链式结构存储数据的数据库技术，以密码学保障数据不可篡改，通过共识协议建立去 中心化信任。将区块链与产品身份证系统深度融合，构建全生命周期管理体系，可有效解决传统模式的信任缺失与数 据安全问题，实现产品信息真实可信、流转全程可溯、责任精准认定。 

Abstract

Product identity plays an important role in anti-counterfeiting traceability, supply chain management, and other fields. However, traditional systems face difficulties such as data tampering, information silos, and high trust costs. With its characteristics of decentralization, tamper resistance, and traceability, blockchain technology provides a new approach to the application of product identity. Blockchain is a database technology that arranges data blocks in chronological order and stores data in a chain structure. It ensures data tamper resistance through cryptography and establishes decentralized trust through consensus protocols. By deeply integrating blockchain with a product identity system and building a whole-life-cycle management system, problems such as lack of trust and data security risks in traditional models can be effectively solved, enabling authentic and trustworthy product information, full-process traceability, and accurate responsibility identification.
