Abstract

The invention relates to the technical field of the Internet, and discloses a cross-chain data processing method and device based on a block chain, which are used for improving the efficiency in the cross-chain data processing process and reducing the resource consumption, and the method comprises the following steps: a first block chain determining data processing content according to a receivedcross-chain data processing request; the first block chain calling a first cross-chain smart contract according to the first call address, and executing a first operation corresponding to the first block chain in the data processing content to obtain a first operation result; the first block chain writing the data processing content and the first operation result into a first account book after reaching a consensus of the first operation result; when the first block chain knows that a second operation result is written into a second account book of a second block chain, obtaining the second operation result from the second account book; and the first block chain writing the second operation result into the first account book.

Description

technical field [0001] The present application relates to the field of Internet technology, and in particular to a blockchain-based cross-chain data processing method and device. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed ledger. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing paradigm for programming and manipulating data through smart contracts composed of code. [0003] With the rapid development of blockchain technology and applications, various independent blockchain networks have emerged, and realizing cross-blockchain tra...
