In the above description, the skilled person can design the instructions according to the disclosed solution of the present disclosure. How the instructions control the operation of the processor is well known in the art and will not be described in detail herein.
< method examples >
The account management method based on the block chain provided in the embodiment. The method may be implemented by an account management system. Specifically, the parking area processing method may be implemented by the article server and the blockchain cluster in the account management system. The account management system may specifically be, for example, the account management system 100 shown in fig. 1.
As shown in fig. 2, the account management method based on the blockchain includes steps S2100 to S2300.
In step S2100, the item server queries whether the balance of the target user account in the target contract account is sufficient in response to a request for the target user account to use the shared item.
Wherein the target contract account is a contract account created by the item server in the blockchain cluster.
In one embodiment of the present disclosure, a target mobile terminal may issue a use request to a shared article, and the shared article may issue a request for use of the shared article by a target user account to an article server in response to the use request. The target mobile terminal may be pre-installed with a de-centering application, and the user may log in the de-centering application using a target user account. That is, the target mobile terminal may be a mobile terminal that logs in to a pre-installed decentralized application using a target user account.
Specifically, the target mobile terminal may obtain the unique identifier of the shared article by scanning the two-dimensional code set on the shared article, or may manually input the unique identifier of the shared article to the target mobile terminal by a user using the target mobile terminal. And the target mobile terminal generates a use request according to the target user account logged in by the target mobile terminal, and sends the use request to the shared object according to the unique identifier of the shared object. In one example, the target mobile terminal may send the usage request to the shared article through short-range communication such as bluetooth or NFC.
The shared article responds to the use request sent by the target mobile terminal, generates a request of the target user account for using the shared article, and sends the request to the article server through the network.
Further, the item server may be a query request to initiate a balance of the target user account in the target contract account to the blockchain cluster in response to the request of the target user account to use the shared item. The blockchain cluster returns the balance of the target user account in the target contract account to the item server in response to the query request.
And the article server determines whether the balance of the target user account in the target contract account is sufficient according to the balance returned by the block chain cluster. Specifically, when the balance is greater than or equal to a preset money threshold, it may be determined that the balance of the target user account in the target contract account is sufficient; and when the balance is less than the amount threshold, determining that the balance of the target user account in the target contract account is insufficient. The amount threshold may be preset according to an application scenario or a specific requirement, and may be 1 yuan, for example.
Step S2200 is that the article server sends a charging start notification for the target account to the blockchain cluster and issues an unlocking instruction to the shared article to control unlocking of the shared article when the article server inquires that the balance of the target user account in the target contract account is sufficient.
And the article server issues an unlocking instruction to the shared article under the condition that the balance of the target user account in the target contract account is sufficient. The shared object can be the shared object which is used for executing the unlocking instruction and completing the unlocking action, so that the user using the target user account can use the shared object.
Step S2300, the blockchain cluster updates the usage status of the target user account to the first status according to the charging start notification, and broadcasts the usage status of the target user account to the blockchain network in which the blockchain cluster is located.
Wherein the first state is a state indicating that the target user account is using the shared item. And under the condition that a charging starting notice aiming at the target user account sent by the item server is received by the block chain cluster, updating the use state of the target user account to a first state to represent that the target user account is using the shared item. In this case, the target user account cannot use other shared items.
Since the blockchain cluster is only a part of devices used in the blockchain network, in order to enable each computer in the blockchain network to update the usage status of the target user account, the blockchain cluster may broadcast the usage status of the target user to the blockchain network in which the blockchain cluster is located, so that all the blockchain clusters in the blockchain network update the usage status of the target user account.
In the embodiment of the disclosure, the user account is managed based on the blockchain technology, and the blockchain technology has decentralized high reliability and cannot be tampered with, so that the safety of the user account can be effectively ensured, and the problem of user fund loss caused by the problem of the operating condition of the article server is avoided.
Fig. 3 shows that in this embodiment, a target contract account and an external account may be created in advance in the blockchain cluster, and the external account may include a user account and a moist account. Wherein, the user account can be controlled by the corresponding user through the mobile terminal installed with the decentralized application; the differentiated accounts may be controlled by the respective item server or by a partner sharing the item, through the respective electronic device in which the decentralized application is installed.
In this embodiment, the target contract account may be divided into divided accounts, and may also be a user account with a value or a refund.
The item server may also interact with the shared item, and in response to a request sent by the shared item for the target user account to use the shared item, send a balance inquiry request of the target user account to the target contract account, and the target contract account returns the balance of the target user account to the item server in response to the inquiry request.
On the basis of the above embodiment, the method may further include steps S4100 to S4300 shown in fig. 4:
in step S4100, the item server responds to the request for the target user account to finish using the shared item, sends a finish charging notification for the target account to the blockchain cluster, and issues a lock closing instruction to the shared item to control locking of the shared item.
In this embodiment, a return button may be provided in the target mobile terminal, and the user may trigger the target mobile terminal to send a return request to the shared item by clicking the return button. The shared item is in response to the return request, a request is issued to the item server for the target user account to end use of the shared item.
The item server may issue a lock-off instruction to the shared item upon receiving a request that the target user account end using the shared item. And the shared object responds to the locking instruction and executes locking action, so that the user finishes using the shared object.
Step S4200, the blockchain cluster determines the usage cost of the shared item used by the target user account this time according to the end charging notification and the pre-stored intelligent contract.
An intelligent contract is code that runs in an etherhouse, visible to the person in need. The Ethenhouse is an open-source public block chain platform, supports the use of a graphic-complete programming language, and can build decentralized applications on the platform. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.
The intelligent contract in this embodiment may be created by the item server and pre-broadcast into the blockchain network for acquisition by the blockchain cluster.
The intelligent contract may record charging rules of the user account, and the blockchain cluster may determine a duration of the shared article used by the target user account when the charging termination notification is received. And obtaining the use cost of the shared article used by the target user account at this time according to the duration and the charging rule recorded in the intelligent contract.
