Abstract

A cross-chain communication method which is applied to a main chain node, at least one cross-chain plug-in is deployed on the main chain node, each cross-chain plug-in corresponds to one side chain node, and the method comprises the steps of receiving a first cross-chain transaction request sent by a first side chain node is received through the first cross-chain plug-in; verifying the first cross-chain transaction request through the first cross-chain plug-in; after the first cross-chain transaction request passes the verification, converting a first cross-chain transaction structure of the first cross-chain transaction request into a transaction data structure which can be identified by the main chain node through the first cross-chain plug-in; and performing consensus on the first cross-chain transaction request of the transaction data structure, and executing a transaction. The invention also provides a cross-chain communication device, a main chain node and a storage medium. According to the invention, cross-chain communication between two heterogeneous block chains can be realized, meanwhile, the implementation cost is saved, and the cross-chain communication performance is improved.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular to a cross-chain communication method, device, main chain node and storage medium. Background technique [0002] The emergence of the side chain mechanism allows digital assets or messages on the blockchain to be safely transferred between independent blockchains (for example, it is possible to safely transfer Ethereum from the Ethereum main chain to other blockchains, and can be safely returned to the Ethereum main chain from other blockchains), thus providing a mechanism to extend the functionality and performance of the main chain. [0003] In practice, if the side chain and the main chain are isomorphic chains, since the communication protocols are compatible with each other, it is relatively easy to realize cross-chain communication between the two chains. However, the more common situation in reality is that the side chain and the main chain are heterogeneous bloc...
