Internet of Things service architecture based on lightweight block chain nodes

The invention discloses an Internet of Things service architecture based on lightweight block chain nodes. The Internet of Things service architecture is composed of a device layer, a full node layer,a block chain network layer, a service layer and an application layer. Internet-of-things equipment is used as a lightweight block chain node, and a point-to-point communication mode in a block chaintechnology is utilized to solve the problem of data exchange between the equipment; meanwhile, due to the characteristic of decentralization of the block chain technology and an encryption algorithmadded with cryptography, the safety problem possibly existing in the untrusted and data sharing process between devices is solved; an intelligent contract is introduced to manage all devices and datainformation of the Internet of Things, the management process is optimized through event triggering and automatic operation of the intelligent contract, and the problem of resource integration and management is solved. 本发明公开了基于轻
