CHAINGE：一种自动更新订阅服务支付细节的区块链解决方案
CHAINGE: A Blockchain Solution to Automate Payment Detail Updates to Subscription Services
摘要：
基于订阅的商业模式的兴起导致客户需要管理其付款的订阅数量相应增加。对于客户来说，这种对多个订阅的支付的管理已经成为一项非常复杂和不安全的任务，特别是当卡丢失、被盗或过期时更新支付细节时。此外，根据安全报告，这个主要是手动的流程很容易出现人为错误、数字欺诈和数据泄露。因此，在本文中，我们提出了一种新的方法来自动化，管理和简化金融供应链的更新和管理支付给用户订阅的过程中所涉及的。这是通过利用Hyperledger Sawtooth区块链框架来实现的，该框架允许消费者在中央数字钱包中输入他们的支付卡详细信息，并将他们的订阅链接到他们的卡。正在更新的卡会触发区块链上的一个事件，这允许在订阅系统上自动更新支付细节。对拟议系统的原型进行的验证测试表明，其目前的实施已安全实现。
英文摘要：
The rise of the subscription-based business model has led to a corresponding increase in the number of subscriptions where a customer needs to manage their payments. This management of payments for multiple subscriptions has become a very complicated and insecure task for customers, especially when it comes to renewing payment details when the card is lost, stolen, or expires. In addition, this, mostly manual, process is vulnerable to human error, digital frauds, and data breaches, according to security reports. Thus, in this paper, we propose a novel approach to automate, manage and simplify the Financial Supply Chain involved in the process of updating and managing payments to user subscriptions. This is done by utilising the Hyperledger Sawtooth blockchain framework, that allows a consumer to enter their payment card details in a central digital wallet and link their subscriptions to their cards. The card being updated triggers an event on the blockchain, which allow for the payment details to be updated on subscription systems automatically. The verification tests performed on the prototype of the proposed system shows that its current implementation has been securely achieved.
