When the user becomes the target user, an intermediate blockchain account can be established for the user, and funds in the intermediate blockchain account can be agreed in a member agreement of the user and the merchant. The intermediate blockchain account enables constraints on the user such that the user can proceed to merchant consumption in compliance with the membership agreement.

In an embodiment of the present application, if the remaining consumption number is equal to 0, the merchant blockchain account prompts that the user fails to consume, and cannot consume.

In an embodiment of the application, when the user is prompted to fail to consume, the user can be prompted to recharge, so that the user can conveniently purchase the service.

In an embodiment of the application, if the remaining consumption number is equal to 0, a setting value may be transferred from the user blockchain account of the user to the merchant blockchain account for consumption, without hindering the user consumption.

In an embodiment of the application, if it is determined that the user is not the target user according to the user identification code, the user block chain account of the user may transfer the setting value to the merchant block chain account for consumption, without hindering the user consumption. In an embodiment of the application, if the user is not the target user, the set value for transferring from the user blockchain account of the user to the merchant blockchain account may be larger than the set value for transferring to the merchant blockchain account when the user is the target user, and the secondary consumption price of the user with pre-stored funds is distinguished from the consumption price of the user without pre-stored funds, so as to attract the user to pre-store funds at a lower price.

Merchant blockchain account in one embodiment of the present application, the set value may be a fee that the merchant charges for each service. The amount charged by the merchant for each service may be determined by dividing the amount spent by the merchant purchasing multiple services by the number of times the merchant purchased the service.

In one embodiment of the present application, the setting value may be varied according to the number of times of consumption purchased by the user. It may be that the more the number of consumption the user purchases, the smaller the setting value, the more the user is attracted to purchase the service.

In one embodiment of the application, if the account balance of the user blockchain account is greater than the set value, the set value is transferred from the user blockchain account to the merchant blockchain account for consumption. Only when the account amount in the user block chain account is enough, the service is provided for the user, the user arrearage is avoided, and the benefit of a merchant is protected.

In an embodiment of the present application, the user blockchain account balance of the user may be acquired from the blockchain according to the user identification code.

In one embodiment of the application, if the account balance of the intermediate blockchain account is not less than the target balance, transferring a setting value from the user blockchain account to the merchant blockchain account for consumption, wherein the target balance is a user deposit. After the user signs an agreement with a merchant for purchasing a plurality of times of services, in order to restrict the user, a transfer deposit can be transferred from the user blockchain account to the intermediate blockchain account, and the user still transfers accounts from the user blockchain account to the merchant blockchain account in the subsequent consumption process, so that the subsequent consumption to the merchant of the user is ensured, and the benefits of both the user and the merchant can be simultaneously protected.

Merchant blockchain accounts in one embodiment of the present application, transfers may be made to merchant blockchain accounts by way of smart contracts.

In an embodiment of the application, a member recharging instruction can be obtained, wherein the member recharging instruction includes a recharging amount, a user blockchain account identifier of a user and a middle blockchain account identifier of the user; and transferring the recharging amount from the user blockchain account of the user to the middle blockchain account of the user according to the member recharging instruction so that the user can recharge money in the middle blockchain account for consumption.

In an embodiment of the application, a member cash withdrawal instruction can be obtained, wherein the member cash withdrawal instruction comprises a cash withdrawal amount, a user block chain account identifier of a user and an intermediate block chain account identifier of the user; and transferring the cash-out amount from the middle block chain account of the user to the user block chain account of the user according to the member cash-out instruction so that the user cash out from the user block chain account to protect personal funds.

In one embodiment of the application, the presentation can be carried out only when the merchant violates or the agreement between the user and the merchant is terminated, so that the benefits of both the user and the merchant are protected.

In one embodiment of the application, if the user does not default for personal reasons or the agreement between the user and the merchant is terminated, the user part of the default money can be deducted if the user initiates a cash withdrawal instruction. A portion of the intermediate blockchain accounts may be transferred to the merchant blockchain account as a default and the cash-out amount may be transferred from the remaining portion of the intermediate blockchain accounts to the user blockchain account. The amount of the default money can be determined according to the withdrawal amount of the user, and the more the withdrawal amount, the more the default money.

In the embodiment of fig. 2, by obtaining a check-in instruction for a user to enter a merchant, the check-in instruction includes a user identification code from which the identity of the user may be identified. And acquiring the residual consumption times of the user from the block chain according to the user identification code, wherein the residual consumption times are generated by purchasing multiple services of a merchant in advance when the user transacts the member. And if the residual consumption times are more than or equal to 1, transferring a set value from the intermediate block chain account of the user to the block chain account of the merchant to consume. Because the user just transfers accounts to the merchant when the store enjoys the service of the merchant, and the user signs in once and transfers accounts to the block chain account of the merchant once, compared with the method that the cost is prestored to the block chain account of the merchant in advance, the loss caused by the fact that the merchant does not provide service for the user after receiving money can be avoided. Because the user transfers the pre-stored funds into the intermediate blockchain account, the user can be restricted to protect the merchant blockchain account of the benefit merchant blockchain account of the merchant.
