[0003] The traditional blockchain transfer system will expose a lot of private information of both parties to the transfer to the public (participating nodes such as miners) when resources are transferred, for example, information such as addresses, transfer amounts, or account balances of both parties, resulting in a certain degree of information Leakage, resulting in relatively low security

Embodiment Construction
[0063] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0064] The blockchain-based resource transfer method provided by this application can be applied to such as figure 1 shown in the application environment. The system involved in the embodiment of the present application may be a distributed system formed by connecting a client and multiple nodes (any form of computing equipment in the access network, such as a server and a user terminal) through network communication.
[0065] see figure 1 , figure 1 It is an optional schematic diagram of the distributed system 100 applied to the blockchain system provided by the embodi...

The present application relates to a block chain-based resource transfer method, device, computer equipment and storage medium. The method includes: decrypting the first structure according to the private key; when the decryption is successful and the first resource value in the first structure includes the resource value to be transferred, creating a second structure; the second structure in the second structure The resource value is the value of the resource to be transferred; the invalid identifier corresponding to the first structure is broadcast to the nodes in the blockchain network; the invalid identifier is used to instruct the node to add the invalid identifier to the invalid identifier set for the first time; according to the second client Encrypt the second structure with the public key of the terminal, and send the encrypted second structure to the second client; broadcast the valid identifier uniquely corresponding to the second structure to the node; the valid identifier is used to instruct the node to add the effective identifier to the in the set of valid identities. By adopting the method, privacy can be protected and security can be improved during resource transfer.
Description
technical field [0001] The present application relates to the field of computer technology, specifically to the field of block chain processing technology, and in particular to a block chain-based resource transfer method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of science and technology, blockchain technology came into being. There are currently many scenarios where blockchain technology is applied to solve problems. Among them, resource transfer using blockchain technology is an important application scenario. [0003] The traditional blockchain transfer system will expose a lot of private information of both parties to the transfer to the public (participating nodes such as miners) when resources are transferred, for example, information such as addresses, transfer amounts, or account balances of both parties, resulting in a certain degree of information Leakage, resulting in relatively low security.
