Abstract

The embodiment of the invention relates to the field of Fintech, in particular to a data verification method and device applied to a block chain. In the embodiment of the invention, a data request mechanism sends a data request to a data storage mechanism; the data request mechanism obtains a request response returned by the data storage mechanism, so that the data request mechanism obtains the second encrypted data; the data request mechanism decrypts the second encrypted data to obtain the second data; the data request mechanism obtains a first Hash value of the first data from the block chain, wherein the first hash value is generated by the data storage mechanism according to the first data and an interference value of the first data and is uploaded to the block chain; and when the data request mechanism confirms that the first hash value is consistent with the second hash value, the data request mechanism obtains the first data from the second data.

Description

technical field [0001] The embodiment of the present invention relates to the field of technology finance (Fintech), in particular to a blockchain data verification method and device. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into Finteh, and Blockchain technology is no exception. However, due to the security of the financial industry , Real-time requirements, but also higher requirements for technology. [0003] Blockchain (Blockchain) is a way for all people to participate in bookkeeping, which has the characteristics of decentralization and trustlessness. The most important thing about the blockchain is to solve the intermediary credit problem. In the past, it was difficult for two people who did not know and trust each other to reach a collaboration, and had to rely on a third party. For example, in payment behavi...
