Problems solved by technology

Due to the non-tamperable modification of the blockchain itself, it is difficult to guarantee that the entire process is not atomic
That is, when the asset is successfully removed from chain A, and chain B fails to accept the asset, there will be a transaction rollback problem of chain A

Abstract

The invention provides an over-chain transaction method based on multiple block chains, a system, equipment and a storage medium. The method comprises the following steps of submitting an over-train transaction testing request by a first application client to a first block chain, configuring the value A1 of a first account to a testing value A2 by a plurality of nodes of the first block chain after a transfer transaction is executed, configuring the value B1 of a second account to a testing value B2 by a plurality of nodes of the second block chain after the transfer transaction is executed, and when the over-chain transaction testing request endorsement succeeds, locking the value A1 and the testing value A2 of the first account and the value B1 and the testing value B2 of the second account; copying the testing value A2 of the first account to the value A1 by the plurality of nodes of the first block chain; copying the testing value B2 of the second account to the value B1 by the plurality of nodes of the second block chain; and when the over-chain transaction execution request endorsement succeeds, writing the value A1 of the first account and the value B1 of the second accountinto the block chain and performing unlocking.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a multi-block chain-based cross-chain transaction method, system, device and storage medium. Background technique [0002] In 2008, a scholar named "Satoshi Nakamoto" published the paper "Bitcoin: A Peer-to-Peer Electronic Cash System", laying the foundation for blockchain technology. In a narrow sense, a blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and cryptographically ensures a non-tamperable and non-forgeable distributed ledger. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate update data, uses cryptography to ensure data transmission and party security, and uses automated script codes to A new distributed infrastructure and computing paradigm that consists of smart contracts to program and manipulate d...
