Cross-chain asset transfer method, apparatus and storage medium

Abstract

The invention provides a cross-chain asset transfer method, an apparatus and a storage medium. The method comprises: receiving first order registration request information sent by a first user terminal of a first user; registering a first order on a first block chain according to the first order registration request information; and generating a first intelligent contract; and generating a first intelligent contract according to the first order registration request information; returning the first account information to the first user terminal for the first user terminal to initiate a first transfer transaction for transferring a plurality of first assets into a designated account on the second block chain according to the first account information, and locking the plurality of first assets through the first hash value; receiving the transaction information of the first transfer transaction sent by the first user terminal and the verification information sent by the server terminal, verifying the transaction information according to the verification information; if the verification is successful, triggering the first intelligent contract to enter an unlocked state; the first key sent by the first client terminal being received and the second asset being unlocked by the first key. The invention can meet the multi-chain mapping requirement through a relatively simple scheme.

Description

technical field [0001] This application relates to the technical field of Internet finance, and specifically relates to a cross-chain asset transfer method, device and storage medium. Background technique [0002] The cross-chain transfer of assets refers to the transfer of assets on different blockchains to achieve rich business applications. [0003] Existing cross-chain transfer technologies include side chain technology, multi-party computing locking technology, etc. Among them, the side chain technology usually anchors the target chain and the source chain, just like the currency anchors gold, the currency is used in the transaction, and can be converted back to gold when needed; the multi-party computing locking technology usually uses other chains Assets are locked through multiple accounts, and assets are mapped to the destination chain at the same time, assets on the destination chain are destroyed when necessary, and assets are unlocked on other chains.

AI Technical Summary

Problems solved by technology

[0004] For the side chain technology, take the more typical rootstock as an example, its defect is that when the side chain and the main chain are anchored for joint mining, it can only be anchored with one chain, and cannot be anchored with multiple chains at the same time;

[0005] For the multi-party computing locking technology, its disadvantage is that although multiple chains can be anchored at the same time, due to the need for multi-party account locking, after the assets are transferred to other people in the mapping chain, the scheme of redeeming and unlocking assets is more complicated.
