The INT project originated from a community practice of Apache Mynewt (Apache open-source IoT operating system). The team initially attempted to define hardware through software to reduce the complexity of hardware development. However, even if the Abstraction layer of the system is defined, how to form a unified ecology between hardware and hardware is still a challenging problem. Later, the team considered driving the integration of different systems through economic means after reflection.INT is a blockchain application platform and interaction standard oriented towards the Internet of Things, based on an economic driven approach. By connecting devices in a parallel chain structure to form a distributed network, consensus algorithms are used to ensure the legitimacy and trustworthiness of transactions between devices. At the same time, different types of devices can be connected to different parallel chains to avoid explosive growth of the total ledger....
