Provided herein is a computer-implemented method for provisioning a token to an appliance. The method includes registering an original account identifier to an appliance, wherein the original account identifier is not associated with any user when registered, associating a device token to the original account identifier, wherein the device token is stored by the appliance, associating a user account identifier to at least one of the device token and the original account identifier, receiving, from the appliance, a transaction request for a transaction, the transaction request including the device token, identifying the user account identifier based on the device token, determining that the transaction is authorized based at least partially on the user account identifier and the original account identifier registered to the at least one appliance, and in response to determining that the transaction is authorized, processing the transaction. A system and appliance are also disclosed.

A method for mediating an atomic swap includes: receiving a swap request from a first computing device including a first address associated with a first blockchain and a network identifier associated with a second blockchain; identifying a second computing device using the network identifier and a second address associated with the second blockchain; generating a proof value and a hashlock using the proof value; transmitting (i) the hashlock and second address to the first computing device, and (ii) the hashlock and first address to the second computing device; verifying a first blockchain transaction on the first blockchain for transfer to the first address, and a second blockchain transaction on the second blockchain for transfer to the second address; and transmitting the proof value to blockchains node associated with the first and second blockchains.

A system is provided as a computer server platform and application programming software installed in primary devices of users for exchanging and trading digital asset securely and anonymously between two users of the system. The digital asset is registered under a device account of a primary device of a user with the system using a unique device account name. The system respects “privacy by design” in GDPR by using device account based-on anonymized data instead of personal account based-on personal data of prior art to ensure the system does not collect, store and process users' personal data in the course of device accounts' set-up and transactions of digital assets.

An Online Software Platform (OSP) may receive a first dataset from a remote client device, and compute an estimated resource, from the first dataset and also per stored digital rules. The OSP may then communicate an aspect of the resource to the remote client device and receive a confirmation of the first dataset. The OSP may then process the first dataset, for matching it with another dataset, either internally or by outsourcing. Either way, the OSP may establish that the first dataset has been matched with a compatible second dataset. The OSP may then input a resource for the first dataset, which is determined according to stored digital rules. The OSP may further create one or more notifications and documents about the matching and the resource, and make them available to the remote client device or even to the device of another remote entity.

Systems, computer program products, and methods are described herein for providing an information feedback loop from one or more third parties to issuing entity in the course of a resource action requiring user-initiated authorization. In the course of user-initiated authorization, information is automatically generated and forwarded to the issuing entity in the form of an advice message. Such data is intelligent forwarded to the appropriate downstream application to streamline user experience, provide pertinent customer feedback, and pre-emptively determine patterns in resource action processing.

A computer-implement system and method for purchasing a non-fungible token (NFT) of a specific event or item is disclosed. The system comprises a processor and a memory unit to store a set of instructions executable by the processor, a database to store a plurality of data associated with the customized NFT, and a user device to provide a digital marketplace that provides graphical user interface. The system sells NFTs related to specific events or items in real-time. The NFTs act as an access pass or voucher. The system directs the customer towards an NFT marketplace via a QR code or an inaudible tone, where the customer purchases or sells the NFT to provide access to the specific event or item. Each NFT has a set of digital attributes and being cryptographically linked with respective event or item. Further, the NFT directly unlocks access related to the specific event or item.

Techniques are described, as implemented by computing devices, to control access to transactions through use of tokenized reputation scores. This is performed by leveraging a blockchain such that a tokenized reputation score is generated or calculated based on an amount of reputation tokens associated with a blockchain account address associated with a service provider account, and by making transactional functionality available to the service provider account based on a comparison of a tokenized reputation score affiliated with the service provider account with a threshold score associated with a transaction.

A method executed by a computing device includes identifying a non-fungible token (NFT) of an object distributed ledger that meets minimum NFT requirements. The method further includes determining whether to select the NFT based on an evaluation of the NFT with regards to an evaluation profile. When selecting the NFT the method further includes to producing a selected NFT and determining reassignment information for the selected NFT. The method further includes facilitating taking control of the selected NFT of a blockchain of the object distributed ledger and updating the selected NFT utilizing the reassignment information for the NFT to produce an updated NFT. The method further includes causing generation of a new block affiliated with the updated NFT via the blockchain of the object distributed ledger, where the new block includes the updated NFT.

A method executed by a computing device includes determining whether baseline content associated with a longevity-contingent instrument is qualified for a proposed a non-fungible token (NFT) for an object distributed ledger. The baseline content includes an obligation provider identifier (ID) and an outcome recipient ID. When the baseline content is qualified, the method further includes determining an exposure level for the NFT and establishing NFT content. The method further includes causing generation of a new block affiliated with the NFT via a blockchain of the object distributed ledger, where the new block includes the NFT content.

A method executed by a computing device includes interpreting a request to generate a non-fungible token (NFT) for an object distributed ledger to produce baseline content that includes an obligation provider identifier (ID) and an outcome recipient ID. The method further includes verifying, validity of the baseline content. When the baseline content is valid, the method further includes determining whether a beneficial improvement is provided to a result of a triggered outcome when a hypothetical change to the obligation provider ID is made. The method further includes an outcome evaluation and establishing NFT content based on the outcome evaluation to include the baseline content. The method further includes causing generation of a new block affiliated with the NFT via a blockchain of the object distributed ledger, where the new block includes the NFT content.
