摘要： 目前服装可追溯体系存在覆盖不全、产权难以保护等问题，中心化账本的数据记录方式存在数据篡改风险，二维码或RFID技术存在防伪性不足问题。针对服装产品溯源与真伪辨识问题，文章提出一种基于权威证明机制的服装可追溯系统设计方案。通过对现有可追溯系统进行分析，并对服装供应链进行剖析分解，指出各环节与区块链技术结合方式。系统借用区块链技术，结合权威证明机制、哈希算法、时间戳技术、智能合约，从数据层、网络层、共识层、激励层、合约层、应用层六部分进行研究，利用去中心化网络结构，实现对服装产品全生命周期的数据录入。同时，解决算力与存储空间不足、节点作恶、数据防篡改、服装实物与数据结合问题，保证服装产品的可溯源性与防伪性。

Abstract： At present， there still exist some problems in clothing traceability system， such as incomplete coverage， difficulty in property rights protection， data tampering risk in centralized account book data recording methods， and lack of anti-falsification of two-dimensional code or RFID technology. To solve the issues concerning of clothing products traceability and authenticity identification of clothing products， a design scheme of clothing traceability system based on proof-of-authority mechanism was proposed. Through the analysis of the existing traceability system， the analysis and decomposition of the clothing supply chain， this paper pointed out the mode for the combination between each step and blockchain technology. This system is focused on the study from six aspects of data layer， network layer， consensus layer， incentive layer， contract layer and application layer， hash algorithm， timestamp technology and smart contract through blockchain technology based on proof-of-authority mechanism， and the data input of the whole life cycle of clothing products was implemented by using decentralized network structure. At the same time， this system can solve the problems of insufficient computing power and storage space， node evil， data tamper proofing， and the combination of clothing objects and data， thereby guaranteeing the traceability and anti-counterfeiting of clothing products.

可追溯系統（traceability system）[1]是指利用与产品一一对应的标志，追溯或跟踪某产品的生产、交易、售后情况的一种保障体系。可追溯体系一方面可以对产生问题的产品进行追溯，以找清问题源头[2];另一方面可对产品进行跟踪，以确定产品流通情况，便于售后处理等问题[3]。

随着人们物质生活水平不断改善，消费者对服装的购买力有较大提升[4]。但鉴于服装品牌、品类繁多，针对服装的溯源仍存在诸多问题;同时，普通消费者不具备对服装真伪鉴别能力。……
