    Abstract: One or more embodiments of the present specification provide blockchain-based data processing computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems. In an implementation, a computer-implemented method includes obtaining, by a first node device of a blockchain and from a distributed database of the blockchain, a target transaction that comprises state information of a target user. A data type of the state information and data content that corresponds to the data type of the state information is identified. A first graphical processing is performed on the data content that corresponds to the data type of the state information to obtain a state graphic that corresponds to the target user, where the first graphical processing is performed based on first predetermined data graphical processing logic that corresponds to the data type of the state information.

    Abstract: One or more embodiments of the present specification provide methods and apparatuses for copyright allocation for a blockchain-based work, which are applied to a blockchain network that includes an original author client device, a co-creation participating user client device, and a first node device. The method includes the following: obtaining, by the first node device, a first target transaction from a distributed database of the blockchain, where the first target transaction includes co-creation participating behavior data of the co-creation participating user for a target work, and the target work is originally created by the original author; and invoking a smart contract corresponding to copyright allocation for the target work, executing logic declared in the smart contract for allocating a copyright share to the co-creation participating user based on the co-creation participating behavior data, and allocating a copyright share of the target work to the co-creation participating user.

    Abstract: Techniques for displaying a payment page based on the proximity of a payment device to a client computing device are described. One example method includes receiving, at a client computing device, a signal when the client computing device is within a predetermined range of a source of the signal; determining, by the client computing device, that the signal is a predetermined characteristic signal sent by an electronic device of a payee; and in response to determining that the received signal is the predetermined characteristic signal, displaying, by the client computing device, a payment page configured to be read by the electronic device of the payee to perform an electronic payment.

    Abstract: Embodiments of the present specification provide a service recommendation method, apparatus, and device. During operation, the system obtains, based on historic information associated with a target user, a user feature and a service-usage feature of the target user for a service; determines a service recommendation scheme by inputting the user feature, the service-usage features, and a service feature of the service into a machine-learning model for recommending services; and recommends a service to the target user based on the determined service recommendation scheme.

    Abstract: The present application relates to the field of computer technologies, and in particular, to a method for controlling display of a screen of a mobile terminal, and a mobile terminal. In the method for controlling the display of the screen of the mobile terminal, the mobile terminal can detect whether a beam emitted by a recognition apparatus arrives. When the mobile terminal detects that a beam arrives, the mobile terminal can determine whether the detected beam is in an inclined state. Once the mobile terminal detects that the beam is in the inclined state, the mobile terminal can adjust a display direction of interface content on a screen of the mobile terminal based on the inclined state of the beam.

    Abstract: Implementations of the present application provide a blockchain-based resource allocation method. A target transaction is obtained, by a first node device in a blockchain network, from a distributed database of the blockchain network. The blockchain network comprises a target user device of a target user and the first node device. The target transaction comprises service behavior data of the target user, and the service behavior data of the target user is generated by the target user device by using a target service. A smart contract corresponding to an allocation of a resource is invoked comprising: executing a resource allocation logic that is stored in the smart contract and that is related to the service behavior data of the target user, and performing the allocation of the resource to the target user.
