4.1 Basic Architecture Logic

The system architecture of AirshipX platform can be simply divided into three layers, protocol layer, extension layer and application layer. Among them, the protocol layer can be divided into storage layer and network layer, which are independent but inseparable. As shown：

The protocol layer refers to the most underlying technology. It mainly includes four aspects: network programming, distributed algorithm, encrypted signature, and data storage technology. The principles of data storage selection are performance and ease of use. Distributed algorithms, encrypted signatures must be used in the process of implementing peer-to-peer networks.

The extension layer is to make blockchain products more practical. This project is an expansion for communication, and "smart contract" is a typical application development at the expansion layer. The so-called "smart contract" is "programmable contract", or "intelligent contract", in which "intelligence" is the intelligence in execution, that is to say, when a certain condition is reached, the contract is automatically executed, such as automatic trade, automatic payment, etc. . Technologies used in the extension layer include distributed storage, machine learning, VR, business collaboration, big data, and more.

The application layer is a product that people can really use directly, and it can also be understood as the browser side (Browser) in a product with a B/S architecture.
