This application relates to re-provisioning of credentials, such as payment credentials, on a second electronic device from one or more credentials previously provisioned on a first electronic device. The one or more previously provisioned credentials may be stored on an external storage system and may be retrieved by the second electronic device for re-provisioning. The second electronic device may re-provision an instance of the one or more retrieved credentials for use in electronic transactions on the second electronic device using a secure element linked to the second electronic device and information that is unique to the one or more credentials being re-provisioned to the second electronic device.

A method for batch processing for a plurality of individual transactions includes generating a batch transaction by aggregating at least some of the plurality of individual transactions according to a setting value of a batch size, and processing the batch transaction via a blockchain network. The generation of the batch transaction includes adjusting the setting value of the batch size based on a monitoring result for a transaction processing status, and generating the batch transaction according to the adjusted setting value.

Methods, systems, and apparatus for executing a smart contract by a blockchain node of a blockchain. An example method includes receiving bytecode of a smart contract; deploying the smart contract, comprising storing the bytecode of the smart contract on the blockchain; compiling, through Just-In-Time (JIT) compilation, the bytecode of the smart contract into machine code; locally storing the machine code in a memory of the blockchain node; and executing the smart contract deployed on the blockchain, comprising determining whether the machine code corresponding to the bytecode of the smart contract is locally stored in the memory of the blockchain node, and interpreting and executing the bytecode of the smart contract if the machine code corresponding to the bytecode of the smart contract is not locally stored.

The present disclosure provides systems and methods for computerized methods and systems for processing transaction disputes and processing transactions associated with compromised accounts. According to one exemplary method, a server receives, from a user device, an instruction for disputing a transaction associated with a user account. The server can initiate, based on a record of the transaction, a dispute investigation, and issue provisional credit to the user account for the transaction. Based on a transaction history associated with the user account, the server can determine a plurality of expected transactions associated with the user account and cause the determined expected transactions to be displayed on the user device. After receiving a transaction authorization for at least one of the plurality of expected transactions, the server can process payments for the at least one of the plurality of expected transactions, and generate a notification indicating a status of the dispute investigation.

Systems and methods for tokenization, management, trading, settlement, and retirement of renewable energy attributes are disclosed. In one embodiment, in an information processing apparatus comprising at least one computer processor, a method for tokenization, management, trading, settlement, and retirement of renewable energy attributes may include: (1) identifying renewable energy generation data associated with a seller to tokenize; (2) generating at least one renewable energy token for the identified renewable energy generation data; (3) writing the renewable energy token to a first distributed ledger; (4) adding the renewable energy token to a digital wallet for the seller; (5) exchanging the renewable energy token for a cash token owned by a buyer by associating the renewable energy token with the buyer and associating the cash token with the seller on the first distributed ledger; and (6) retiring the renewable energy token.

A payment processing system includes a user terminal, a merchant terminal, an account institution, a settlement institution and an acquiring institution. The user terminal is configured to send transaction information; the account institution is configured to generate a transaction order and send it to the settlement institution, and the settlement institution is configured to forward it to the acquiring institution; the acquiring institution is configured to process the transaction order and send the order processing result to the settlement institution, and the settlement institution is configured to forward the result to the account institution; the account institution is configured to deduct user funds according to the result and send payment result notification information to the settlement institution, and the settlement institution is configured to forward the notification to the acquiring institution; and the acquiring institution is configured to send a payment result to the merchant terminal.

A first communication terminal receives, from a second communication terminal, use request information indicating a request by a user for using a particular service of one or more services provided by a provider. The first communication terminal transmits to a management system information indicating an amount of currency information for using the particular service, and provides the particular service to the second communication terminal in response to reception of a notification from the management system, the notification indicating completion of transfer of currency information from the user to the provider for the indicated amount.

Disclosed are a personal card management system and method by reverse automatic synchronization. The personal card management system by reverse automatic synchronization comprises: a public interest corporation terminal which designates a beneficiary for facilitating the benefits of donations and provides a card company system with deposits; a card management server which registers the card of the beneficiary designated by the public interest corporation terminal and manages the transaction history of the registered card; and a beneficiary terminal which requests the registration of the card for receiving the benefits to the card management server and synchronizes the relevant transaction history with the card management server.

This disclosure describes aspects of an efficient blockchain API communication mechanism that reduces the energy usage and data usage. In some examples, a publish-subscribe mechanism is used for completed transaction receipts for blockchain transactions of a blockchain. The publish-subscribe mechanism uses an open source remote procedure call protocol or hypertext transfer protocol (HTTP). Components of a distributed blockchain application use a single transport or communications protocol for both synchronous and asynchronous communications.

A method executed by a computing entity includes interpreting digital records to produce a first digital record representing a first contingent asset. The method further includes interpreting a first authenticity indicator associated with the first digital record to produce a first contingent asset risk level. When the first contingent asset risk level is greater than a contingency risk threshold level, the method further includes establishing a set of first contingent asset available terms for a corresponding set of portions of the first contingent asset, generating a set of first smart contracts to represent the set of portions to include the set of first contingent asset available terms and a contingent status. The method further includes causing generation of a non-fungible token to represent the set of first smart contracts in an object distributed ledger.
