With over 6 million users across 33 countries, Coinbase is an industry leader building the bridge between traditional finance and the blockchain space. Our goal at Coinbase is to provide simple and secure exchange services to users worldwide for blockchain-based digital assets. The networks that power these digital currencies are complex and significantly different from traditional banking integrations. In this presentation, I provide an overview of blockchain protocols and discuss how our unified architecture for payment services abstracts away integration-specific logic from core transaction processing. We will dive into the details of Coinbase’s Bitcoin, Ethereum, and US banking integrations and compare how they implement the generalized service interface.
