Method and apparatus for resource exchange

One or more non-transitory computer-readable media configured with instructions executable by one or more processors of a user terminal to cause the one or more processors to perform operations comprising:

• in response to a resource transfer operation initiated by a user on a transaction client of the user terminal to transfer a resource, generating a resource transfer request, wherein the resource transfer request includes resource transfer information that includes an certificate identifier;
• sending, through a transaction server corresponding to the transaction client, the resource transfer request to a resource transfer server coupled with the transaction server, causing the resource transfer server to:
• obtain a resource transfer certificate from a blockchain according to the certificate identifier, wherein the resource transfer server is a node device of the blockchain;
• perform authenticity verification on the resource transfer certificate;
• in response to successful authenticity verification on the resource transfer certificate;
• generate a resource transfer identifier for the resource transfer information;
• and
• return the resource transfer identifier to the transaction client through the transaction server;
• and
• based on the resource transfer identifier, initiating a resource transfer confirmation to the resource transfer server, causing the resource transfer server to complete resource transfer processing based on the resource transfer information corresponding to the resource transfer identifier.

A user terminal comprising:

• one or more processors;
• and
• a memory communicatively connected with the one or more processors, wherein the memory is configured to store instructions executable by the one or more processors to cause the one or more processors to perform operations comprising:
• in response to a resource transfer operation initiated by a user on a transaction client of the user terminal to transfer a resource, generating a resource transfer request, wherein the resource transfer request includes resource transfer information that includes an certificate identifier;
• sending, through a transaction server corresponding to the transaction client, the resource transfer request to a resource transfer server coupled with the transaction server, causing the resource transfer server to:
• obtain a resource transfer certificate from a blockchain according to the certificate identifier, wherein the resource transfer server is a node device of the blockchain;
• perform authenticity verification on the resource transfer certificate;
• in response to successful authenticity verification on the resource transfer certificate;
• generate a resource transfer identifier for the resource transfer information;
• and
• return the resource transfer identifier to the transaction client through the transaction server;
• and
• based on the resource transfer identifier, initiating a resource transfer confirmation to the resource transfer server, causing the resource transfer server to complete resource transfer processing based on the resource transfer information corresponding to the resource transfer identifier.
