A computer-implemented method and system for blockchain network congestion-adaptive handling of events relating to digital assets, including creation and transfer operations. A congestion metric is measured to determine current congestion of the blockchain network. If below a first threshold level, then digital asset request are implemented using blockchain transactions at layer 1 as they are received. If the metric is above the first threshold level, then the received requests are deferred until a trigger is detected, whereupon the requests are processed at layer 2 and a batch blockchain transaction is used to implement the two or more requests by recording the updated state on chain. When the metric falls below a second threshold, the process reverts to using layer 1 blockchain transactions instead of deferring requests for layer 2 batch processing.

Systems and methods for blockchain network congestion-adaptive digital asset event handling

A web-based commerce system may maintain a transaction state between the commerce system and a blockchain application for recording transactions involving NFTs on a blockchain. When a buyer intends to purchase an NFT, the commerce system must coordinate on-chain and off-chain processes with a merchant storefront and a blockchain application. Unlike conventional approaches, which perform these various processes in a serial, integrated manner, the commerce system and blockchain application separately execute these operations and perform the off-chain and on-chain processes independently.

Maintaining blockchain state when performing non-blockchain commerce workflow

The disclosed embodiments include processes that securely approve and execute exchanges of data between systems, apparatuses, and devices in a computing environment. For example, a terminal device may establish communications with a client device across a direct channel of communication, and may initiate an exchange of data with that additional device across the direct communications channel. The initiated data exchange may be characterized by a value of a data-exchange parameter, and the terminal device may determine to authorize the current data exchange in real-time based on cryptographically secure distributed ledger data maintained by the client device and provided to the terminal device across the direct communications channel. Further, and based on transmitted confirmation data, the client device may generate additional, cryptographically secure of the distributed ledger data to reflect the authorized data exchange.

Secure offline approval of initiated data exchanges

A computer-implemented method is disclosed. The method includes: receiving video data for a live video stream; identifying a product that is displayed in a video frame of the live video stream; obtaining identifying information for a viewer of the live video stream; determining a product variant preference for the viewer; obtaining a graphical representation of the product variant; and providing modified video data of the live video stream based on presenting the graphical representation of the product variant as overlay content for the live video stream. Related apparatuses and computer-readable media are also disclosed.

Systems and methods for customizing live video streams

Methods and system for managing inventory in the context of online transactions involving blockchain-based payments. Examples may include determine an inventory count associated with an item with which a user device initiates a payment involving a blockchain transaction. The system determines a likelihood of completion with regard to the blockchain transaction based on one or more metrics related to recent transactions on the blockchain. Responsive to the likelihood of completion being above a minimum threshold value, the system records a hold in memory in association with the inventory count and then determines that the blockchain transaction has been completed and, in response, removes the hold from memory and decrements the inventory count.

Methods and systems for inventory management for blockchain-based transactions

Methods and systems for access control in an online environment, such as an e-commerce platform. The system receives a designation of a non-fungible token (NFT) collection in connection with a merchant account, each NFT having a respective combination of attributes. An association is detected between a product record and a combination of two or more of the attributes and the system automatically generates an access rule with regard to the product record that is conditional on ownership of an NFT in the collection that has the combination of the two or more attributes. When a request for access is received, the access rule is applied to provide a user device with access to the one or more product records based on verification of the ownership by the user device of an NFT that meets the condition.

Methods and systems for access control in a computing system

A computer system for provisioning a data transfer method is disclosed, comprising a processor, and a communications module and a memory coupled to the processor. The memory stores instructions that, when executed by the processor, cause the computer system to: receive a provisioning request for a data transfer method; send, to a server associated with the data transfer method, a request, based on the provisioning request, for assignment of a data transfer identifier; receive, from the server, the data transfer identifier responsive to the request for assignment of the data transfer identifier; obtain a data transfer token corresponding to the data transfer identifier by: sending, to a token service provider, a request for the token comprising the data transfer identifier; receiving, from the token service provider, a data transfer token in response to the request for the token; and, send a reply to the provisioning request comprising the token.

System and method for provisioning a data transfer application

Methods and systems for customizing user interface content. Customization is based on one or more non-fungible tokens associated with a wallet identifier linked to a user device. The method may include receiving a request for interface content from a user device and identifying at least one non-fungible token associated with the user device. The interface content is customized for the user device based on the at least one non-fungible token to generate customized interface content, and the customized interface content is transmitted to the user device for output on a user interface.

Methods and systems for providing differentiated user interfaces

The disclosure generally describes computer-implemented methods, software, and systems, including a method for placing a card into an alert state. An alert detection indication is received during an attempted data exchange using a permanent account number (PAN) associated with a card. The alert detection indication is received by an electronic controller embedded in the card and is received through an interface. The alert detection indication indicates that the PAN has an alert state identified for the PAN by an entity that issued the card. An operational mode of the card is modified into the alert state by the electronic controller and is based on receipt of the alert detection indication. An electronic display indicating that the card is in the alert state is displayed by the electronic controller.

The disclosed embodiments include computer-implemented systems, apparatuses, and processes that automatically generate and provision notification data to a dynamically selected set of network-connected devices operating within a computing environment. For example, an apparatus receives a first signal including first information identifying first data exchanges initiated during a first temporal interval and compute, based on the first information, an expected value of a parameter of the first data exchanges during a second temporal interval. When the expected parameter value is inconsistent with a target parameter value, the apparatus loads, from a storage unit, second information characterizing a second data exchange capable of initiation during the second temporal interval, and generates and transmits a second signal, via the communications unit, to a client device disposed that is disposed proximate to a predetermined geographic position and that exhibits a first device characteristic associated with the second data exchange.

Automatic generation and provisioning of notification data to dynamically selected network-connected devices

There is provided a computing device and method to perform a data transfer using a document. Data to define at least one parameter of a data transfer is defined from data in the document. The document may have text characters or images of text characters (or both) for the data. A GUI may display the document and receive input to identify the data and define the at least one parameter. The document image may be processed to determine the text characters such as by OCR. The document may be a photo (image) captured by a camera on or coupled to the computing device. A GUI may be defined to provide workflow to define the data transfer signal such as a message. Functionality to capture text characters from documents, particularly images, may be added to applications such as via a plug in or otherwise.

Computing device and method to perform a data transfer using a document

A method and computer system for detecting, utilizing at least one sensor associated with the computer system, an attempt to establish short-range communications between a device and a short-range communications module coupled to the computer system. The method and computer system further configured for determining that no short-range communication was received by the computer system via the short-range communications module and providing a signal to the device to enable a short-range communications transceiver at the device.

Methods and systems for using a distributed ledger to record bot mitigation test results and enable servers to determine a bot mitigation score for a remote device based on previously recorded test results associated with the remote device. The server may detect a trigger for bot mitigation in association with a remote device, obtain identifying data regarding the remote device and search a distributed ledger using the identifying data to locate one or more test results stored in records on the distributed ledger containing the identifying data. It may then determine a bot likelihood score based on the one or more test results, compare the bot likelihood score to a threshold and, in response to the comparison, execute a mitigation action.

Systems and methods for bot mitigation

A computer-implemented method and system for blockchain network congestion-adaptive handling of events relating to digital assets, including creation and transfer operations. A congestion metric is measured to determine current congestion of the blockchain network. If below a first threshold level, then digital asset request are implemented using blockchain transactions at layer 1 as they are received. If the metric is above the first threshold level, then the received requests are queued until a queue trigger is detected, whereupon the queued requests are processed at layer 2 and a batch blockchain transaction is used to implement the two or more requests by recording the updated state on chain. When the metric falls below a second threshold, the process reverts to using layer 1 blockchain transactions instead of queueing requests for layer 2 batch processing.

The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that, among other things, generate and provision digital tokens based on dynamically obtained contextual data. For example, an apparatus may receive first information that characterizes an exchange of data initiated by a first application program executed by the apparatus, and may generate and transmit a signal to a computing system through a programmatic interface associated with a second application program executed by the apparatus. In some instances, the first signal may include the first information and data that instructs the computing system to obtain a digital token representative of a data type available for use in the data exchange. The apparatus may also receive a second signal that includes the digital token and based on the digital token, perform operations that present second information characterizing the available data type on an interface.
