Cross-block chain asset transfer method and device

Abstract

The invention provides a cross-block chain asset transfer method and device. The method comprises the following steps: receiving a cross-block chain asset transfer request of an asset transfer initiating user; carrying out asset transfer bridging processing on the current block chain and the bridge chain by a bridge node of the block chain to which the initiating user belongs according to the asset transfer request; wherein the bridge node is a node which is preset by each block chain and is used for performing cross-chain transaction, and the bridge chain is a block chain formed by registering the bridge node of each block chain; and according to the asset transfer request, carrying out asset transfer bridging processing on the block chain to which the target account belongs and the bridge network by the bridge node of the block chain to which the target account belongs to complete cross-block chain asset transfer. Cross-chain digital asset transfer can be achieved between two accounts on different service block chains, the assets are protected by a consensus mechanism of the block chains in the whole process, and the risk of client digital asset loss existing in a traditional scheme is solved.

Description

technical field [0001] The present invention relates to data processing technology, specifically a cross-block chain asset transfer method and device. Background technique [0002] Blockchain technology can be used to realize a decentralized digital asset management system. This kind of digital asset management system does not require a trusted central organization, but multiple independent nodes reliably maintain digital assets on the blockchain through consensus algorithms, and digital assets can be transferred conveniently and reliably between different accounts (such as transfer). [0003] At present, it is still a technical problem to achieve the same convenient and reliable asset transfer between different blockchains. The existing solutions use intermediaries such as exchanges to realize cross-chain asset transfers. Exchanges open accounts in different chains , the requester of the cross-chain asset transfer first transfers the ownership of the asset to the exchange...

AI Technical Summary

Problems solved by technology

On the one hand, if a reliable exchange cannot be found, then cross-chain asset transfer will not be possible; In order to control the assets, the account of the exchange temporarily owns the customer's assets. If the exchange is hacked, or the exchange maliciously embezzles the customer's assets, the customer's digital assets will suffer serious losses in these cases.
