Virtual Asset Processing Methods of Blockchain Networks

Virtual Asset Processing Methods of Blockchain Networks

I. Glossary

Term DefinitionsVirtual Assets (Virtual Assets) are electronic vouchers issued by the first institution or the second institution to motivate users to consume or give back to users, such as points, coupons, vouchers, etc. Blockchain Points (Blockchain Points) are points that users obtain by exchanging virtual assets provided by the first institution, which can be circulated and traded in the blockchain network. Blockchain Network (Blockchain Network) is a network composed of multiple nodes, used to store and manage blockchain points, and to perform related transactions. Blockchain Service Center (Blockchain Service Center) is a platform for users, first institutions, second institutions and blockchain networks to interact, providing services such as identity authentication, point exchange, and information query. User Terminal (User Terminal) is an electronic device used by users to access the blockchain service center and initiate a point exchange request. First Institution (First Institution) is a merchant, enterprise or government department that provides virtual assets to users. Second Institution (Second Institution) is a merchant, enterprise or government department that users can use the redeemed blockchain points to redeem virtual assets provided by it. Point Exchange Request: A request initiated by a user to the blockchain service center to exchange the virtual assets provided by the first institution into blockchain points. Virtual Asset Exchange Request: A request initiated by the second institution to the blockchain service center to exchange the blockchain points that the user has exchanged for the virtual assets provided by the second institution. Digital Certificate: An electronic certificate issued by an authentication node in the blockchain network to verify the identity of the user, the first institution, and the second institution. Digital Signature: An electronic signature generated by the user, the first institution, and the second institution using a private key to encrypt the transaction information to ensure the authenticity and integrity of the transaction information. 2.

III. Answers to short-answer questions

The embodiment of the present invention solves the problems of inconvenient points query, cumbersome redemption process, ineffective circulation, and low security in the existing points redemption system.

The technical solution of the embodiment of the present invention is: connect the user, the first institution, and the second institution to the blockchain network, and the user converts the virtual assets provided by the first institution into blockchain points through the blockchain service center, and then uses the converted blockchain points to redeem the virtual assets provided by the second institution.

The user initiates a points redemption request at the terminal. After the blockchain service center verifies the user's identity information, it calls the smart contract to convert the virtual assets provided by the first institution submitted by the user into the corresponding number of blockchain points, and saves the redemption record in the blockchain network.

The blockchain points information redeemed by the user is saved in the blockchain network in the form of blockchain points redemption records, which can be recorded in the form of a running account or stored in the form of key-value pairs in the state database.

The user sends a virtual asset exchange request to the blockchain service center. After the blockchain service center verifies the user's identity information and blockchain points information, it calls the smart contract to exchange the blockchain points submitted by the user into the corresponding number of virtual assets provided by the second institution, and saves the exchange record in the blockchain network.

Before accessing the blockchain network, the user, the first institution, and the second institution need to first apply for a digital certificate from the blockchain network and use the digital certificate to sign the transaction information to ensure identity security.

The blockchain network adopts the characteristics of distributed storage and non-tamperability to ensure the traceability of the points exchange process and improve the security and trustworthiness of the relevant information involved in the points exchange process.

The blockchain service center is a platform for users, the first institution, the second institution and the blockchain network to interact, providing services such as identity authentication, points exchange, and information query.

The embodiment of the present invention utilizes the advantages of decentralization, non-tamperability, and traceability of blockchain technology, solves the security and trust problems existing in the existing points exchange system, and improves the efficiency and convenience of points exchange.

The application scenarios of the embodiment of the present invention include but are not limited to points exchange, coupon exchange, and voucher exchange.
