The embodiment of the invention discloses a near field payment method, device and equipment. The scheme comprises the following steps: a payment terminal scans and finds a peer-to-peer connection group created by user equipment based on a wireless network communication technology; obtaining discovery information issued by the user equipment in the peer-to-peer connection group; and decoding the discovery information, obtaining service data corresponding to the user equipment, and executing a payment service corresponding to the user equipment according to the service data.

The one or more embodiments of the specification provide a data account access authorization method and device, which is applied to a block chain node; an account type supported by the block chain includes a data account; the data account is used to maintain business data required for contract calculation of a smart contract deployed on the block chain; an account structure of the data account includes an authorization field used to maintain access authorization information corresponding to the data account; the method includes: receiving a data account authorization transaction initiated by a management party corresponding to the data account and directed to the data account; the data account authorization transaction includes an account identifier of a user account and access permission information of the data account authorized to the user account; in response to the data account authorization transaction, determining whether the management party has a management right corresponding to the data account; if yes, filling the corresponding relationship between the account identifier of the user account and the access permission information into the authorization field in the data account as the access authorization information corresponding to the data account.

The application discloses an industrial internet data sharing optimization method based on intelligent sharding decision blockchains. Through adaptive sharding decision of a blockchain system, the method can effectively break through the scalability bottleneck of the blockchain. Specifically, the method adds a blockchain sharding decision factor to an action space of a deep reinforcement learning algorithm, jointly considers sharding decision, unloading decision, block size and block interval, introduces a cloud-edge collaboration computing paradigm, models an optimization problem as a Markov decision process, and solves the optimization problem by using a deep reinforcement learning method. Simulation results show that the total delay of industrial internet data sharing and the blockchain transaction throughput obtained by the method are better than those of other methods.

The application is suitable for the technical field of computer and financial technology, and provides a digital asset management method and system based on asynchronous settlement and ownership locking, which comprises the following steps: receiving an ownership change request of a target asset unit from a requestor; giving a trusted timestamp to the received ownership change request; determining the sequence of the ownership change request according to the trusted timestamp, and entering an ownership verification process; after reaching a predetermined settlement time point, asynchronously processing all locked target asset units in the current settlement period, generating a new asset unit controlled by a second ownership certificate for each locked target asset unit to replace the old asset unit; and unlocking the asset unit to complete the ownership transfer. The application can realize efficient, safe, certain and flexible ownership transfer, and significantly improve the transaction throughput.
