An Internet of Things data transaction architecture based on block chain and a transaction security method thereof

Abstract

The invention discloses an Internet of Things data transaction structure based on block chain, which comprises a local wireless sensing network, a data providing node, a data consuming node, a data storing node, a leaflet and transaction credentials. The invention also discloses a transaction security method based on the data transaction architecture of the Internet of Things, comprising the following steps: S1, a leaflet construction sending stage; S2, a data uploading stage; S3, a transaction preparation stage; S4, a transaction processing stage; The invention solves the problem that a largenumber of isolated islands of internet of things data exist due to centralized storage in the prior art, which greatly hinders the flow of internet of things data and wastes the value contained in the internet of things data.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a blockchain-based Internet of Things data transaction architecture and a transaction security method thereof. Background technique [0002] The origin of blockchain technology and the publication of a paper called Bitcoin: A Peer-to-Peer Electro-nic Cash System by a scholar named Satoshi Nakamoto in 2008, and the subsequent release of Bitcoin was the first widely used The trustless cryptocurrency has been running smoothly for nearly ten years. Subsequently, on the basis of Bitcoin, many other forms of cryptocurrency emerged. The prosperity of cryptocurrency has led to the rapid development of its underlying blockchain technology, and new concepts such as smart contracts and smart property are derived from blockchain technology. came out and was quickly accepted by the market. A smart contract is a computerized transaction protocol that enforces the te...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a blockchain-based Internet of Things data transaction architecture and transaction security method with fast circulation speed, wide circulation range, high system reliability and good security, which realizes The decentralization of transactions solves the problem of the existence of a large number of IoT data islands in the existing technology due to centralized storage, which greatly hinders the circulation of IoT data and wastes the value contained in IoT data
