Embodiment Construction

[0031] The technical solutions of the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0032] Blockchain technology is a distributed ledger technology and an Internet database technology. Its essence is decentralization, and a growing distributed data record can be jointly maintained by multiple parties. Decentralization can solve the problem of data retention in traditional data trading centers, as well as the loss of customers caused in the process of data query, distrust among users and re-selling of data assets, and to a certain extent improve data security, data Privacy and data control.

[0033] The blockchain protects the security of data transmission and access through cryptography technology, making it difficult for any party to tamper, deny, or forge. In a narrow sense, blockchain is a kind of non-tamperable and unforgeable decentralized shared ledger that combines data blocks ...

Abstract

The embodiment of the invention discloses a data interaction method and device based on a block chain. The method comprises the steps that a first device broadcasts a transaction request through a block chain network; the transaction request at least comprises an identifier of an address of a target intelligent protocol; the target intelligent protocol at least comprises first data information andtransaction information; the first device receives second data information returned by node devices in the block chain network after the target intelligent protocol is executed according to the transaction request; the second data information at least comprises the first data information and / or data information obtained after the first data information is processed; and if the first device confirms a transaction according to the second data information, payment operation is executed according to the transaction information in the target intelligent protocol, and the obtained payment result iswritten into the block chain. By the adoption of the data interaction method and device, the security and non-repudiation in the data transaction process can be effectively ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a blockchain-based data interaction method and device. Background technique [0002] With the development of the Internet, online transactions have become a trend. However, the traditional way of using the Internet to conduct online transactions may easily lead to the disclosure of transaction information of both parties during data transactions, and the entire transaction process is controlled by a third-party platform, resulting in no way to verify the authenticity of the transaction process. Contents of the invention [0003] The embodiment of the present invention provides a data interaction method and device based on blockchain, which can make the data transaction process more secure and realize the non-repudiation of the transaction process, and facilitate the data transaction process. [0004] In the first aspect, the embodiment of the present invention provid...
