账本：Stripe的用于跟踪和验证资金流动的系统

Last Black Friday to Cyber Monday, Stripe processed 300 million transactions with a total payment volume of $18.6B—and the Stripe API maintained greater than 99.999% availability. Underlying these metrics is our Global Payments and Treasury Network (GPTN) that manages the complexity of accepting payments, money storage, and money movement. Today, Stripe supports more than 135 currencies and payment methods through partnerships with local banks and financial networks in 185 countries. These entities provide different interfaces, data models, and behaviors, and Stripe continually manages this complexity so developers can quickly integrate the GPTN into their businesses.

上个黑色星期五到网络星期一，Stripe处理了3亿笔交易，总支付金额达到186亿美元，而Stripe API的可用性超过99.999%。这些指标的基础是我们的全球支付和财务网络（GPTN），它管理着接受支付、资金存储和资金流动的复杂性。如今，Stripe通过与185个国家的当地银行和金融网络合作，支持超过135种货币和支付方式。这些实体提供不同的接口、数据模型和行为，Stripe不断管理这种复杂性，以便开发人员可以快速将GPTN集成到他们的业务中。

Internally, Stripe needs to guarantee that what we expect to happen during payment processing actually happens for internal customers and external auditors of our data. We built Ledger, an immutable and auditable log, as a trustworthy system of record for all of our financial data. Ledger standardizes our representation of money movement, and it serves as the scalable foundation for our automated Data Quality (DQ) Platform—guaranteeing Stripe faithfully manages money for users.

在内部，Stripe需要保证我们在支付处理过程中所期望的事情实际上发生在我们的内部客户和外部审计员的数据中。我们构建了Ledger，一个不可变且可审计的日志，作为我们所有财务数据的可信系统记录。Ledger标准化了我们对资金流动的表示，并作为我们自动化的数据质量（DQ）平台的可扩展基础，确保Stripe忠实地为用户管理资金。

Many existing systems provide primitives for accurate accounting, but the real world is imperfect, incomplete, and constantly changing. We witness basic and obvious failures like malformed reports or propagated errors from banking or network partners, and also broad macroeconomic changes such as currencies ceasing to exist or large banks collapsing overnight. While we aspire to an orderly ideal, at Stripe scale, that’s impossible—instead we built a system that keeps these imperfections manag...
