Problems solved by technology

[0004] However, at present, the effective data collected by a large number of IoT / sensing devices cannot be confirmed, which leads to a small range of data applications and a small number of users on the one hand. On the other hand, the people who need to use the data have a low degree of trust in the data and are unwilling Purchase, and thus make the liquidity of data not high, unable to play its due social and economic value

Embodiment Construction

[0032] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] see figure 1 As shown, the embodiment of the present invention provides a blockchain-based data acquisition transaction system, including a blockchain, a data manager, a data consumer, and several data sensing devices, wherein the blockchain includes interconnected public chains Data exchange can be performed between the public chain and the alliance chain. Both the public chain and the alliance chain are equipped with storage institutions. The storage institutions in the alliance chain are also called distributed ledgers.

[0034] The data managers in this embodiment include administrative agencies and enterprises. Enterprises are used to deploy data sensing devices as the data source of the system, and data consumers are used to purchase corresponding monitoring data from the system as needed.

[0035] In actual use, the range of moni...

Abstract

The invention discloses a data collection transaction system and method based on a block chain, and relates to the field of block chains and the Internet of Things. The system comprises a block chain,a data manager, a data consumer and a plurality of data sensing devices, and the block chain comprises a public chain and an alliance chain which are connected with each other. The data manager comprises an administrative institution and an enterprise, the enterprise is used for deploying the data sensing device as a data source of the system, and the data consumer is used for purchasing corresponding monitoring data from the system as required. The administrative institution is used for auditing the account of the accounting node to be added into the alliance chain. The enterprise is used for adding the data sensing device into the block chain, the data consumer and the data sensing device have corresponding wallet addresses and private keys in the block chain, and the data consumer candirectly send data purchase information to the data sensing device and perform transaction. The system can determine the right of the data, improve the fluidity of the data, and improve the economic value of the data.

Description

technical field [0001] The invention relates to the fields of block chains and the Internet of Things, in particular to a block chain-based data acquisition transaction system and method. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing paradigm that uses contracts to program and manipulate data. [0003] In recent years, the blockchain technology has developed rapidly and has become the most innovative new technology at present. At the same time, because the blockchain not only has a unique block chain data structure, but also has a decentralized structure and data immutability, so , Blockchain technology has broad application prospects in the financial and electr...
