A computer-implemented method for processing blockchain-based transactions, the computer-implemented method including: receiving a target transaction initiated by a member node device in a blockchain, wherein the target transaction comprises a unique identifier of the target transaction; querying a transaction idempotent table on the block chain to determine whether the transaction idempotent table has stored a transaction idempotent record corresponding to the unique identifier of the target transaction; and in response to determining that the transaction idempotent table has not stored the transaction idempotent record corresponding to the unique identifier of the target transaction, recording the target transaction in a candidate block on the blockchain.

A method, computer program product, and computer system for receiving a first scan of an identifier from a first computing device is disclosed. The identifier is associated with a financial transaction. A second scan of the identifier is received from a second computing device. The financial transaction is processed based upon, at least in part, receiving the second scan of the identifier from the second computing device.

In one embodiment, a processing device receives a request to claim ownership of a first hosted media item on a first media sharing platform, wherein the request is received from a rights holder that holds one or more rights to a claimed media item that is incorporated into the first hosted media item. The processing device adds an indicator of the ownership of the rights holder to a first entry for the first hosted media item in a data store. The processing device determines that a second hosted media item having a threshold similarity to the first hosted media item is hosted by a second media sharing platform. The processing device automatically adds an indicator of the ownership of the rights holder to a second entry for the second hosted media item without receiving a separate request to claim ownership of the second hosted media item.

A computer-implemented method for processing blockchain-based transactions, the computer-implemented method including: receiving a target transaction initiated by a member node device in a blockchain, wherein the target transaction comprises a unique identifier of the target transaction; querying a transaction idempotent table on the block chain to determine whether the transaction idempotent table has stored a transaction idempotent record corresponding to the unique identifier of the target transaction; and in response to determining that the transaction idempotent table has not stored the transaction idempotent record corresponding to the unique identifier of the target transaction, recording the target transaction in a candidate block on the blockchain.

A system may include one or more server devices disposed within a remote network management platform. The server devices may communicate with computing devices that are disposed within a managed network. The server devices may store a representation of software programs determined as installed on each of the computing devices. The server devices may also determine, by comparing software license rights to the representation of the software programs determined to be installed on each of the computing devices, whether the managed network is in compliance with the software program license rights. The devices may additionally provide, to a client device that is disposed within the managed network, a representation of a graphical user interface that denotes whether the managed network is in compliance with the software program license rights. The graphical user interface may include a reclamation rules page.

Described are a signature verification method, apparatus, and system. The method includes: encrypting a third-party payment identifier and payment information according to a first key to obtain a first signature; encrypting a third-party client identifier and first signature information according to a second key to obtain a second signature; and providing the third-party client identifier, the first signature information, and the second signature to a client server for verification.

An asset right management system based on blockchain and a method thereof are disclosed. In the system, an asset smart contract of the asset is pre-deployed on a blockchain network, and an asset smart contract is executed to generate a fungible ownership token representing the ownership of the asset, and generate a non-fungible use-right token representing the right to use the asset, based on the ownership token; when the asset smart contract receives proceeds which is obtained through a transaction of the use-right token, the asset smart contract calculates and transfers an profit-sharing amount of each owner, so as to achieve the technical effect of improving convenience in rights management and income of the asset.
