Abstract

The invention provides a cross-chain transaction verification method of heterogeneous block chain, an engine and a device, and a storage medium, and the method comprises the steps: receiving first cross-chain transaction request information transmitted by a first application chain, and obtaining the attribute information of the first application chain according to the transaction information obtained through the analysis of the cross-chain transaction request information; determining a first verification rule corresponding to the first application chain block chain according to the attribute information, the first verification rule being recorded on a verification engine of the relay chain; and executing a first verification rule according to the attribute information to verify whether thefirst cross-chain transaction conforms to the first verification rule. Through the IBTP message transmission protocol, the verification engine is configured to register the application chains receiving different verification rules, and the respective verification rules are matched and verified for the application chains when the cross-chain transaction is sent, so that the cross-chain action between the heterogeneous block chains is truly realized.

Description

technical field [0001] This application relates to the field of blockchain information technology, and specifically relates to a heterogeneous blockchain cross-chain transaction verification method, engine, device and storage medium. Background technique [0002] At present, there are three main cross-chain methods of blockchain technology: notary mechanism, relay / side chain mechanism and hash lock mechanism. Among them, the relay / side chain mechanism is mainly used in the relay chain and multiple isomorphic chains for cross-chain, while in the cosmos project, although the cross-chain transactions of heterogeneous blockchains are realized on the surface, in essence it is Through bridging technology, each heterogeneous chain is converted into an isomorphic chain that conforms to the verification rules of the relay chain, and the cross-chain transaction realized is only the cross-chain transaction of assets. Contents of the invention [0003] In view of the above defects or...
