Bytetrade is a decentralized value exchange and trading infrastructure for the future of blockchain. It has invented a new architecture, the Blockchain-EdgeNode-Client (BEC) structure, in which a client is a lightweight software for users. This client is flexible and can be deployed on browsers, mobile or any devices, but it does not require a lot of computation power or storage. The introduction of an edge node between the user client and the blockchain will bring more powerful functions to users than normal clients, such as: an everlasting running trading bot, more private data storage, computation over private data and business logics, cost-effective P2P communication, and acting as a smart cache between the blockchain and the client.
