Cross-block chain asset management method and equipment, computer-readable storage medium, and computer program product

Abstract

The embodiment of the invention relates to a cross-block chain asset management method and equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: at the management equipment, in response to receiving a request of a user for recharging a second block chain based on a first token of a first block chain, generating a multi-signature address, and configuring the multi-signature address to allow to change associated data of the multi-signature address in response to the fact that multi-signature information of the user and the secondblock chain passes verification; generating first transaction data in response to the confirmation that the multi-token address receives the to-be-recharged first token, so as to generate second tokenfor the smart contract of the second blockchain, the first transaction data at least indicating to recharge the to-be-recharged first token from the multi-token address to the receiving address; acquiring multiple signature information of the user and the second block chain for the first transaction data; and sending multi-signature information for the first transaction data to a second block chain, so that the second block chain provides a second token for an account associated with the user in response to confirmation that the multi-signature information passes verification.

Description

technical field [0001] Embodiments of the present disclosure generally relate to blockchain management methods, and in particular, to methods, devices, computer-readable storage media, and computer program products for cross-blockchain asset management. Background technique [0002] In many fields such as finance and asset management, blockchain has increasingly prominent application prospects due to its technical advantages such as decentralization, immutability, and traceability. Since there are many scenarios in finance and asset management that require asset transfer between users, when users on both sides of the transaction are in different blockchains, it is necessary to transfer assets between blockchains based on different distributed accounting mechanisms and different token values. Interoperability of assets, such as asset exchange, recharge or withdrawal across blockchains. [0003] The traditional cross-blockchain asset management scheme is, for example, that bo...

AI Technical Summary

Problems solved by technology

In the above-mentioned traditional cross-blockchain asset management scheme, the assets of both parties to the transaction usually need to be configured as a centralized asset custodian to interact. Once the asset custodian is compromised or actively acts maliciously, it will Threats to asset security on the blockchain
