To manage property records using a multi-layered hybrid distributed ledger architecture, identification information for a particular property is obtained and transmitted to at least one participant in a public distributed ledger network for a public distributed ledger layer. Ownership information for the same particular property is obtained and transmitted to at least one participant in a federated distributed ledger network for a federated distributed ledger layer. Transaction-related documents for the same particular property are obtained and transmitted to at least one participant in a private distributed ledger network for a private distributed ledger. The distributed ledger layers are different layers of a property distributed ledger each having a separate set of consensus rules for appending distributed ledger data to the respective layer. This allows for the immutable preservation of royalty terms and conditions for a property or asset using the distributed ledger.

The instant disclosure illustrates how the privacy and security of activities occurring on distributed ledger-based networks (DLNs) can be enhanced with the use of zero-knowledge proofs (ZKPs) that can be used to verify the validity of at least some aspects of the activities without private information related to the activities necessarily being revealed publicly. Methods and systems that are directed at facilitating the tracking and recovery of assets stolen on ZKP-enabled DLNs while preserving the confidentiality of the tokens are presented herein.

A system includes a purchase portal configured to receive a purchase order from a customer, wherein the purchase order includes a service from each of a plurality of service providers. When receipt of the purchase order is detected, a processor determines first and second ones of the service providers associated with the purchase order; and establishes a trust relationship between the first service provider and the second service provider in a context of the customer. The processor also sends a first request for a first trust artifact to the first service provider and a second request for a second trust artifact to the second service provider; receives the first trust artifact from the first service provider, receives the second trust artifact from the second service provider, sends the first trust artifact to the second service provider, and sends the second trust artifact to the first service provider.

The present application provides a method for implementing a middleware based on EMV, a terminal device, and a computer-readable storage medium. The method includes: establishing a middleware based on EMV L2, wherein the middleware provides a first interface for an upper-layer application of the terminal device to call; after the middleware receives a calling request for the first interface sent by the upper-layer application according to detected information of a IC card, calling an interface of an Entry library according to the calling request to obtain a return result of the Entry library, wherein the return result of the Entry library comprises an application identifier of the IC card; and determining an EMV L2 library matching the IC card based on the application identifier, and calling an interface of the EMV L2 library matching the IC card, to complete a contactless process with the IC card.

A method comprises receiving a route of an aircraft, identifying a plurality of service providers to provide data services for the aircraft based on the route, receiving data from the plurality of service providers associated with the data services, transmitting the data received from the plurality of service providers to the aircraft, determining a total amount associated with all of the data services provided by the plurality of service providers, and transmitting information on the total amount associated with all of the data services provided by the plurality of service providers.

A computer-implemented method is disclosed. The method includes: receiving transfer parameters associated with a request for a first transfer of resources, the transfer parameters including an identifier of a designated transferor associated with the first transfer; determining that the transferor is eligible to access at least one protected data source based on the transfer parameters; generating a request message for the request including reference data for accessing the at least one protected data source; and providing, to a computing device associated with the transferor, the request message.

System and method are described for creating and validating identities across multiple blockchains. According to an embodiment, a system uses decentralized resources to receive an enrollment request comprising entity information to create a multi-chain identity of an entity and create an account with a global identifier for the entity and one or more decentralized identities (DIDs), each associated with a cryptographic blockchain of a set of supported cryptographic blockchains. The system maintains a mapping of the global identifier and the one or more DIDs created, share the global identifier and the one or more decentralized identities in a digital wallet associated with the entity. In an embodiment, the digital wallet is implemented as an application to be run on a computing device associated with the entity. The digital wallet stores the global identifier, the one or more decentralized identities, and corresponding cryptographic keypairs associated with each of the one or more DIDs.

A method, apparatus, and computer program product for alternative payment transactions are provided. An example computer-implemented method includes receiving a first request for payment associated with a first transaction that includes one or more first payment parameters and generating an initial payment responsive to the first request for payment based upon the first payment parameters. The computer-implemented method also includes determining first alternative payment data based upon first payment attribute data of a first user associated with the first transaction. The first payment attribute data is associated with non-cash liquid assets of the first user. The computer-implemented method additionally includes modifying the initial payment based upon the first alternative payment data and effectuating the modified initial payment from a first user account associated with the first user in satisfaction of the first transaction. The computer-implemented method may subsequently include modifying the first payment attribute data of the first user.
