Abstract Traceability can be referred to as the ability to track and trace information. Application of traceability can create transparency in supply chains. Conventionally available, centralized traceability solutions are not preferable for supply chains as they are exposed to many problems such as data manipulations, single point of failure, etc. Blockchain, the recently emerged distributed ledger technology, is gaining popularity with its tremendous applications in various fields, particularly in supply chain management. Technically, blockchain is a decentralized and distributed database where information can be securely recorded. Blockchain-based traceability solutions can tackle the shortcomings of centralized traceability solutions. Firms have already started incorporating blockchain into their supply chain activities in order to improve the transparency through tracking and tracing the events. This paper ultimately aims to present an overview of the various blockchain-based traceability solutions reported in the literature. Primarily, this work provides an insight on the possibilities of blockchain traceability solutions in making a supply chain transparent. Apart from this, it analyses how blockchain traceability solutions affect the visibility of various supply chain distribution network designs, and gives an outline on how technologies such as the Internet of Things (IoT), and smart contracts elevate the opportunities of blockchain. In order to demonstrate how blockchain traceability solutions improve supply chain transparency, a Proof of Concept (PoC) for a cold chain scenario is presented using Microsoft Azure Blockchain Workbench.

通过基于区块链的可追溯性实现供应链透明度：带演示的概述

摘要 可追溯性可以称为跟踪和追溯信息的能力。可追溯性的应用可以在供应链中创造透明度。传统上可用的集中式可追溯性解决方案不适合供应链，因为它们面临许多问题，例如数据操作、单点故障等。 最近出现的分布式账本技术区块链因其在各个领域的巨大应用而越来越受欢迎，尤其是在供应链管理方面。从技术上讲，区块链是一个去中心化的分布式数据库，可以安全地记录信息。基于区块链的追溯解决方案可以解决集中式追溯解决方案的缺点。公司已经开始将区块链纳入其供应链活动，以通过跟踪和追踪事件来提高透明度。本文最终旨在概述文献中报道的各种基于区块链的可追溯性解决方案。主要是，这项工作提供了对区块链可追溯性解决方案在使供应链透明方面的可能性的见解。除此之外，它还分析了区块链可追溯性解决方案如何影响各种供应链分销网络设计的可见性，并概述了物联网 (IoT) 和智能合约等技术如何提升区块链的机会。为了展示区块链可追溯性解决方案如何提高供应链透明度，
