Internet of Things service architecture based on lightweight block chain nodes

Abstract

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.

Description

technical field [0001] The present invention belongs to the field of block chain technology, the field of computer network communication, the field of Internet of things, etc., and the framework is applied to fields such as smart logistics, smart transportation, and smart home. Background technique [0002] A blockchain, first proposed by Satoshi Nakamoto to implement Bitcoin, is a linked-list-like data structure with a series of blocks, each block usually containing the hash of the previous block, a timestamp and some form of transaction data. It is a data structure that only appends data, once a block is added it cannot be modified later. A blockchain is a peer-to-peer distributed ledger where anyone can independently verify the authenticity of recorded transactions. Compared with the data maintenance method of the central server, the blockchain does not have records that can be leaked to the outside world. In the case of a public blockchain, anyone can create a public / ...

AI Technical Summary

Problems solved by technology

Public blockchains can be used by any party to store information in addition to the cryptocurrency transactions typically stored on it, which increases the size of the blockchain and makes it unaffordable for smaller devices in IoT architectures to use for storage areas Storage space for block chain copies

[0007] Running energy consumption issues: The consensus process of the existing blockchain public chain requires a lot of calculations. The consensus calculation process relies on a stable pool of miners, and some computationally intensive tasks need to be performed to add new blocks to the blockchain , the process consumes computing resources and power that conventional IoT devices cannot afford

[0008] Scalability issues: Under the Internet of Things architecture, data collection and transmission sometimes need to consider the real-time nature of data transmission, while the data consensus process of the traditional blockchain itself is slow, and the block generation time of the traditional Bitcoin blockchain is fixed at 10 minutes, this parameter cannot meet the real-time requirements of data in the Internet of Things environment

This makes light clients more efficient in terms of storage, but increases the bandwidth overhead of the device
