Problems solved by technology

In this way, the number of data interactions in the blockchain network is large, and data synchronization is frequent, resulting in low performance of the blockchain system
At the same time, data interaction through the above methods will leak the number of transactions, and the leakage of the number of transactions will easily expose business secrets

Embodiment 1

[0050] figure 1 It is a schematic flowchart of the blockchain cross-chain data interaction method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the blockchain cross-chain data interaction method provided in this embodiment includes:

[0051] S101, blockchain A processes the acquired original file through a preset Hash algorithm to obtain the FileHash of the original file;

[0052] What needs to be understood is that in a blockchain cross-chain data interaction, it includes the blockchain that sends data (ie: blockchain A in this application document) and the blockchain that receives data (ie: blockchain A in this application document) Blockchain B).

[0053] S102, block chain A chains FileHash in block chain A, and obtains the first chain-up certificate;

[0054] Among them, on-chain refers to the Hash (ie FileHash) and time of saving files on the blockchain.

[0055] S103, after the blockchain A performs the preset number of on-chain actions...

Embodiment 2

[0076] figure 2 It is a schematic flow diagram of the block chain cross-chain data interaction and verification method provided by the second embodiment of the present invention; refer to figure 2 , the blockchain cross-chain data interaction and verification method provided in this embodiment includes:

[0077] S201, blockchain A processes the acquired original file through a preset Hash algorithm to obtain the file hash FileHash of the original file;

[0078] What needs to be understood is that a blockchain cross-chain data interaction includes the blockchain that sends the data (ie: blockchain A in this application document) and the blockchain that receives the data (ie: blockchain A in this application document) Blockchain B).

[0079] S202, block chain A chains FileHash in block chain A, and obtains the first chain-up certificate;

[0080] Among them, on-chain refers to the Hash (ie FileHash) and time of saving files on the blockchain.

[0081] S203, after the block...

Abstract

The present invention relates to the technical field related to blockchain, in particular to a blockchain cross-chain data interaction and verification method, a blockchain system and a storage medium. Among them, the blockchain cross-chain data interaction method includes: blockchain A processes the acquired original file through the preset Hash algorithm to obtain the FileHash of the original file; blockchain A chains the FileHash on blockchain A to obtain The first on-chain certificate; when blockchain A performs the preset number of on-chain behaviors, blockchain A generates a block based on the preset number of on-chain behaviors, and extracts the Blockhash of the block header in the block; blockchain A Call the interface provided by blockchain B to chain Blockhash on blockchain B; when blockchain B chains Blockhash on blockchain B, it will get the second chaining certificate; blockchain A receives Blockchain B sends back the second on-chain certificate.

Description

technical field [0001] The present invention relates to the technical field related to blockchain, in particular to a blockchain cross-chain data interaction and verification method, a blockchain system and a storage medium. Background technique [0002] Blockchain is a decentralized database and a new application of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The blockchain includes a series of data blocks associated with each other using cryptographic methods, and each data block contains information about blockchain network transactions. Data interaction between different blockchains is called cross-chain data interaction. Cross-chain data interaction is a bridge that connects scattered blockchain islands. [0003] In the existing technology, when performing cross-chain data synchronization and interaction between different blockchains, the method of data interaction is mainly used w...
