This article examines the potential of blockchain technology to revolutionize the jewelry supply chain by enhancing trust, transparency, and efficiency. Utilizing Ethereum, we developed a blockchain network tailored to the industry's needs. Blockchain operates as a secure, immutable ledger, ensuring data integrity and transparency while preventing fraud and tampering due to its decentralized nature. Ethereum's key features, including nodes, addresses, and smart contracts, make it an ideal platform for this application. The system incorporates robust security measures, addressing vulnerabilities such as reentrancy attacks and unauthorized access. Performance tests on networks demonstrated the solution's viability, with Layer 2 optimizations reducing transaction costs. The system also uses IPFS (InterPlanetary File System) to store certificate templates in order to improve scalability and data accessibility. Six primary participants in the supply chain, from miners to customers, engage with the blockchain, ensuring full traceability and transparency. Certificates are dynamically generated by retrieving transaction hashes from the blockchain. The certificate template is stored on the InterPlanetary File System (IPFS), and when needed, the relevant data is populated into the template in real-time to produce the certificate. While challenges remain in terms of industry-wide adoption and regulatory compliance, the solution's potential to enhance transparency and efficiency positions it as a significant advancement for the jewelry supply chain within the Industry 4.0 framework.
本文探讨了区块链技术通过增强信任、透明度和效率来彻底改变珠宝供应链的潜力。我们利用以太坊开发了一个满足该行业需求的区块链网络。区块链作为一个安全、不可变的账本运行，确保数据的完整性和透明度，同时因其去中心化的性质防止欺诈和篡改。以太坊的关键特性，包括节点、地址和智能合约，使其成为此应用的理想平台。该系统采用了强大的安全措施，解决了诸如重入攻击和未经授权访问等漏洞。对网络的性能测试证明了该解决方案的可行性，二层优化降低了交易成本。该系统还使用星际文件系统（IPFS）来存储证书模板，以提高可扩展性和数据可访问性。供应链中的六个主要参与者，从矿工到客户，都与区块链进行交互，确保完全可追溯性和透明度。证书通过从区块链中检索交易哈希动态生成。证书模板存储在星际文件系统（IPFS）上，需要时，相关数据实时填充到模板中以生成证书。虽然在行业广泛采用和监管合规方面仍存在挑战，但该解决方案增强透明度和效率的潜力使其成为工业4.0框架内珠宝供应链的一项重大进步。
