Abstract

The invention discloses a block chain-based Internet of Things data transaction architecture, including: a local wireless perception network, data providing nodes, data consumption nodes, data storage nodes, leaflets, and transaction credentials; and an Internet of Things-based data transaction architecture The transaction security method comprises the following steps: S1, leaflet construction and sending stage; S2, data upload stage; S3, transaction preparation stage; S4, transaction processing stage; The existence of isolated islands of Internet data has greatly hindered the circulation of Internet of Things data and wasted the value contained in 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...
