What is a crypto exchange architecture?
Could you elaborate on the structure and workings of a cryptocurrency exchange architecture? I'm curious to know the fundamental components that enable such platforms to facilitate the buying, selling, and trading of digital currencies. Are there specific technologies or frameworks that underpin these systems? Additionally, how do these architectures ensure security, scalability, and reliability to meet the demands of a rapidly growing cryptocurrency market? Furthermore, what are some of the challenges and considerations that need to be addressed in designing and maintaining a robust crypto exchange architecture?
