A cryptocurrency exchange architecture refers to the underlying structure that enables the buying, selling, and trading of digital currencies. It consists of several key components: the front-end interface, where users interact with the platform; the back-end systems, which handle transactions, order matching, and wallet management; and security protocols to protect funds and personal data. The architecture must ensure scalability, speed, and high uptime to handle large volumes of trades. Additionally, it incorporates integration with blockchain networks and regulatory compliance mechanisms to ensure seamless operations and trustworthiness in the exchange environment. Proper architecture is crucial for a secure, efficient crypto exchange.
