Abstract

The application provides an asset management method, system, electronic equipment and storage medium based on a blockchain, wherein the method binds a first non-homogeneous pass corresponding to a target user, a second non-homogeneous pass in a target virtual scene and a third non-homogeneous pass corresponding to information of each digital asset of the target virtual avatar. The method comprises the steps of combining a first non-homogeneous pass for identity authentication and a third non-homogeneous pass for virtual avatar asset management in a virtual scene to form a combinable non-homogeneous pass. The user can associate and uniformly manage a plurality of digital assets of the digital avatar in the corresponding virtual scene.

Description

Asset management method, system, electronic equipment and storage medium based on blockchain Technical Field The application relates to the technical field of Internet, in particular to an asset management method, system, electronic equipment and storage medium based on a blockchain. Background Non-homogeneous universal certificate (Non-Fungible Tokens, NFT) is universal of digital or real world assets, has irreplaceable and inseparable characteristics, and is currently used in the fields of artwork collection, game props, domain names, identity authentication, copyrights, leases, and the like. NFTs are issued on a blockchain to specify ownership of a particular asset. Each NFT is associated with some unique data, typically some digitized content file (or reference thereto), and is managed by a smart contract. The blockchain has the key characteristics of multiparty maintenance, non-falsification, openness and transparency, is a system for cooperation among multiple persons/multiple objects which lack trust or are weak in trust according to a set consensus rule, and becomes a good choice for establishing a distributed identity authentication system. Blockchain-based distributed identity systems have some problems to be solved, applicability, private key management (loss), and in addition most blockchain identity authentication keep data in third party systems (e.g., a wallet holding information is located in the memory of a computer or server). At present, the identification is carried out by adopting the non-homogeneous universal certificate based on ERC-721. The ERC-721 protocol is a de facto standard that currently generates non-homogenous evidence on ethernet blockchains and other blockchains. However, because the ERC-721 based pass can only be mapped to a single item (identity) and cannot be associated with other items (identities), when managing a plurality of digital avatars (avatars, corresponding accounts) of a real user in a plurality of virtual scenes (metauniverse), the account cannot be associated and managed uniformly. Disclosure of Invention In order to solve the problems, the application provides an asset management method, an asset management system, electronic equipment and a storage medium based on a blockchain, which solve the technical problem that one user cannot manage a plurality of digital assets of a plurality of digital avatars in the prior art. In a first aspect, the present application provides a blockchain-based asset management method, where at least one account of a user and at least one account of a virtual scene are set on a blockchain, where the virtual scene includes at least one virtual avatar, the method includes: Receiving a non-homogeneous certificate passing request of a target user; Acquiring identity authentication information of the target user according to the non-homogeneous pass request; generating a corresponding first heterogeneous pass according to the identity authentication information of the target user; Generating a second non-homogenous pass corresponding to a target virtual scene according to the first non-homogenous pass of the target user, wherein the target virtual scene comprises a target virtual avatar corresponding to the target user; acquiring information of at least one digital asset corresponding to the target virtual avatar in the target virtual scene according to the second heterogeneous certificate; and generating third non-homogeneous pass corresponding to the information of each digital asset of the target virtual avatar respectively according to the information of the at least one digital asset, and binding the first non-homogeneous pass corresponding to the target user, the second non-homogeneous pass in the target virtual scene and the third non-homogeneous pass. According to an embodiment of the present application, optionally, in the above-mentioned asset management method based on blockchain, before the step of generating the corresponding first heterogeneous universal certificate according to the identity authentication information of the target user, the method further includes: Generating a pair of public key and private key according to the identity authentication information of the target user, and generating a wallet address through the public key; Binding the identity authentication information of the target user with the wallet address; Wherein the first heterogeneous pass is associated with the wallet address. According to an embodiment of the present application, optionally, in the above-mentioned asset management method based on blockchain, the first heterogeneous universal certificate, the second heterogeneous universal certificate and the third heterogeneous universal certificate are encrypted by the private key. According to an embodiment of the present application, optionally, in the above-mentioned asset management method based on blockchain, after the step of generating the corresponding first heterogeneous universa
