Abstract

This application relates to the field of Internet technology, and discloses a blockchain-based cross-chain data processing method and device for improving the efficiency of cross-chain data processing and reducing resource consumption. The cross-chain data processing request determines the data processing content; the first blockchain calls the first cross-chain smart contract, executes the first operation corresponding to the first blockchain in the data processing content, and obtains the first operation result; the first The blockchain writes the data processing content and the first operation result into the first ledger; the second blockchain obtains the data processing content from the first ledger; the second blockchain invokes the second cross-chain smart contract to execute the data processing content In the second operation corresponding to the second block chain, the second operation result is obtained; the second block chain writes the second operation result into the second ledger; the first block chain obtains the second operation result from the second ledger; The first blockchain writes the second operation result into the first ledger.

Description

[0001] The present invention is an application filed August 15, 2019, Application No. 201910752817.7, entitled divisional application filed invention, "a cross-link data processing method and apparatus based block chain," the. Technical field [0002] The present application relates to the field of Internet technologies, and particularly to a data processing chain across the method and apparatus for block-based chain. Background technique [0003] Block chain is a chain data structure one kind of data blocks in a sequential manner combined into a linked in chronological order, and in a way to ensure non-cryptographic tampering and unforgeable distributed books. Broadly speaking, the block chain technology is the use of block data structure chain to validate and store the data, the use of distributed nodes consensus algorithm to generate and update data, use patterns of cryptography to ensure secure data transfer and access, the use of automated scripts a transcoding contract consi...
