In this way, the interests of the data matching party will be lost
[0006] 3. If the data matchmaker provides the token and the link address of the data interface of the data provider to the data buyer after matching, then the data matchmaker, buyer and provider will easily fail to reach a consensus on the number of purchased tokens

Embodiment 1

[0057] This embodiment provides a smart contract and an asymmetric encryption mechanism on the blockchain to ensure that a third party participates in matching data transactions in a credible manner.

[0058]Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptographic methods. Each data block contains a batch of Bitcoin network transaction information. It is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

[0059] A smart contract is a computer protocol designed to disseminate, verify or enforce contracts in an informational manner.

[0060] A smart contract on a blockchain platform refers to a piece of code deployed on a shared and replicated ledger, which...

Embodiment 2

[0105] On the basis of Embodiment 1, this embodiment provides a blockchain-based third-party trusted data transaction system, which is mainly used to implement the steps of the blockchain-based third-party trusted data transaction method in the first embodiment above. ,See image 3 , the blockchain-based third-party trusted data transaction system provided in this embodiment includes: a creation unit 21, a display unit 22, a purchase unit 23, a sending unit 24, a receiving unit 25, an acquisition unit 26, a verification unit 27 and a payment unit 28.

[0106] The creation unit 21 is used for the data matching party to create a blockchain data transaction platform;

[0107] The display unit 22 is used for the data provider to display the information of the data to be sold on the smart contract of the blockchain data transaction platform;

[0108] The purchase unit 23 is used for the data purchaser to submit a data purchase request on the block chain data transaction platform ...

Abstract

The invention provides a blockchain-based third-party trusted data transaction system and method, including a data buyer, a data provider, and a data matchmaker; the data matchmaker creates a blockchain data transaction platform; the data provider is on the platform The information on the data to be sold is provided on the smart contract; the data buyer makes a data purchase request on the platform for the intended data information; the data is written into the token using the key signature as the unique identifier, and the token is sent to the data buyer; The data buyer signs the token and pays the token to the data provider; the data provider verifies that the signature information belongs to the data buyer and the data matchmaker, and sends the corresponding data to the data buyer; the data provider submits the token to The blockchain data trading platform, the platform pays the corresponding amount to the data provider. Therefore, the solution provided by the present invention can ensure that the data provider and the data purchaser conduct guaranteed data transactions through a third party.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a blockchain-based third-party trusted data transaction system and method. Background technique [0002] Existing data transactions are generally purchased directly from the data provider by the data buyer. After the transaction is successful. The data provider will provide a token and data interface to the data buyer. The data buyer can use this token to obtain the corresponding purchased data information through the data interface at the specified time. [0003] Since the transaction is directly contacted by the data buyer and the data provider in this transaction method, it is difficult to match and cannot form a scale effect. It is difficult to introduce a third-party data matchmaker in the existing transaction form. The reason is that the addition of data matching parties will easily generate distrust. Distrust will have the following problems: [0004] 1. If the dat...
