For example, in an alternative scheme, before extracting the digital rmb of the first identity corresponding account, the method may further include:

the terminal prompts the target object to input the password of the digital RMB, verifies the password, and extracts the digital RMB of the account corresponding to the first identity if the verification is successful.

The verification is exclusive verification of the digital RMB, namely, the digital RMB is verified in a double verification mode.

For example, the redemption request may further include: the credit terms for merchant a and the credit terms for merchant B. After the point duration is set, points of different merchants can be managed, and disputes caused by successful redemption due to improper duration are avoided.

Illustratively, the redemption response includes: merchant B points and merchant B point periods.

For example, before sending the point trading interest notification to the server of the merchant B, the method may further include:

and the blockchain server sends a query request to the merchant B server, wherein the query request is used for querying the point balance of the merchant B corresponding to the second identity of the second terminal, if the point balance is greater than the point of the merchant B, a point exchange notification is sent to the merchant B server, and otherwise, a redemption refusal notification is sent to the second terminal.
