Problems solved by technology

However, the current data transactions are dominated by centralized platforms and characterized by offline data forms. This method is powerless in dealing with near-real-time and efficient transactions of massive IoT data in the Internet of Everything era. Transaction participants are very limited
At the same time, the existing methods of using blockchain technology for data point-to-point transactions cannot complete the near-real-time transactions of IoT data, and there is no mention of automatic preprocessing of data

Embodiment 1

[0022] see figure 1 , the present invention provides a decentralized IoT data transaction system. The system includes data supplier 1, data supplier 2, data supplier 3, ..., data supplier M, data demander 1, data demander 2, data demander 3, ..., data demander N, blockchain network BC1 and anchor node 1.

[0023] Data suppliers 1, 2, 3...M only act as data suppliers and are responsible for providing data. Each data supplier integrates a processing module (referred to as "processing" in the figure), and communicates with the blockchain network through Dapp BC1 interacts, but does not act as any working node required for BC1 operation (that is, does not undertake any nodes such as bookkeeping nodes, endorsement nodes, sorting nodes, etc.); data demanders 1, 2, 3...N, only as data demanders Responsible for purchasing data and interacting with the blockchain network BC1 through Dapp, but not as any working node required for BC1 operation (that is, not assuming any nodes such as ...

Abstract

The invention discloses a decentralized Internet of Things data transaction system, which is implemented based on a block chain network. The Internet of Things data provider publishes the information of tradable data to the block chain network through a smart contract, and realizes the transaction based on a smart contract. Automatic point-to-point data transactions, the data supplier obtains the digital certificate and delivers the data, and the system records the execution result in the blockchain ledger. Among them, the data supplier only acts as a data provider, and the data demander only acts as a data demander, and neither acts as an accounting node on the blockchain network. The decentralized Internet of Things data transaction system proposed by the present invention is a high-efficiency, high-quality, and short-cycle Internet of Things data transaction method based on blockchain technology, which can realize the security of Internet of Things data generated by users (terminal devices) , Paid, and quickly used by the demand side, to achieve the purpose of ensuring the fairness of the data supply and demand sides and the legal and compliant use of IoT data through technical means.

Description

technical field [0001] The invention relates to the technical fields of Internet of Things data processing, transaction and block chain, in particular to a decentralized Internet of Things data transaction system. Background technique [0002] At present, the society has entered the era of big data, data has become an important means of production, and data transactions are gradually forming a market scale. More and more Internet companies, artificial intelligence companies, universities, governments, think tanks and other organizations are participating in it. However, the current data transactions are dominated by centralized platforms and characterized by offline data forms. This method is powerless in dealing with near-real-time and efficient transactions of massive IoT data in the Internet of Everything era. Transaction participants are very limited. At the same time, the existing methods of using blockchain technology for data point-to-point transactions cannot comple...
