Blockchain, the underlying technology of digital currency, such as Bitcoin, has the characteristics of decentralization, stability, security, anonymity, and nontampering. Blockchain is being applied in an increasing number of fields. Supply chain finance is a financing model in which banks connect core enterprises with upstream and downstream enterprises to provide flexible financial products and services. In the traditional supply chain finance, the core enterprises with strong competitiveness and a large scale play an irreplaceable role in managing the supply chain information flow, logistics, and capital flow, which results in inequality and information asymmetry. Fraud in supply chain finance is also very serious. To solve the problems of the traditional supply chain finance, in this article, we build a new type of supply chain financial platform that uses blockchain technology to manage the whole process. This supply chain financial platform solves the problem of nontrust among the participants in the supply chain, improves the efficiency of the capital flow and information flow, reduces costs, and provides better financial services to the relevant parties in the supply chain. To protect users' privacy, we propose a new method of using homomorphic encryption in the blockchain to meet the needs of sensitive data privacy protection in supply chain financial scenarios.

使用区块链的供应链金融创新

区块链作为比特币等数字货币的底层技术，具有去中心化、稳定、安全、匿名、不可篡改等特点。区块链正在越来越多的领域得到应用。供应链金融是银行将核心企业与上下游企业连接起来，提供灵活的金融产品和服务的一种融资模式。在传统的供应链金融中，竞争力强、规模大的核心企业在管理供应链信息流、物流、资金流等方面发挥着不可替代的作用，造成了不平等和信息不对称。供应链金融欺诈也很严重。为解决传统供应链金融存在的问题，在本文中，我们构建了一种新型的供应链金融平台，使用区块链技术进行全流程管理。该供应链金融平台解决了供应链参与者之间的不信任问题，提高了资金流和信息流的效率，降低了成本，为供应链相关方提供了更好的金融服务。为了保护用户隐私，我们提出了一种在区块链中使用同态加密的新方法，以满足供应链金融场景中敏感数据隐私保护的需求。并为供应链相关方提供更好的金融服务。为了保护用户隐私，我们提出了一种在区块链中使用同态加密的新方法，以满足供应链金融场景中敏感数据隐私保护的需求。并为供应链相关方提供更好的金融服务。为了保护用户隐私，我们提出了一种在区块链中使用同态加密的新方法，以满足供应链金融场景中敏感数据隐私保护的需求。
