A method and system of providing verification of information of a user relating to an attestation transaction is provided, and includes sending a request for information of the user, wherein the information has been previously attested to in an attestation transaction stored within a centralized or distributed ledger at an attestation address; receiving at a processor associated with a verifier the information of the user; sending a cryptographic challenge nonce; receiving at the processor associated with the verifier the cryptographic challenge nonce signed by the user's private key; verifying user identity with the cryptographic challenge nonce signed by the user's private key; deriving a public attest key by using the information of the user; deriving an attestation address using the public attest key; and verifying the existence of the attestation transaction at the attestation address in the centralized or distributed ledger.

The present disclosure describes transaction-enabling systems and methods for enabling machine resource transactions. A system can include a machine having at least one of a compute task requirement, a networking task requirement, and an energy consumption task requirement; and a controller. The controller can include a resource requirement circuit to determine an amount of a resource for the machine to service task requirement, a resource market circuit to access a resource market, and a resource distribution circuit to execute a transaction of the resource on the resource market in response to the determined amount of the resource.

Systems and methods for forward market price prediction and sale of energy storage capacity are disclosed. An example transaction-enabling system may include a fleet of machines having an aggregate energy storage capacity; and a controller, comprising: an external data circuit structured to monitor an external data source and collect data from the external data source; an expert system circuit structured to predict a forward market price for energy storage capacity based on the collected data and the aggregate energy storage capacity; and a smart contract circuit structured to automatically sell at least a subset of the aggregate energy storage capacity on a forward market for energy storage capacity in response to the predicted forward market price.

Systems, methods, and computer media for authenticating and verifying transactions using a distributed-ledger-based chain of custody are described herein. A transactable credit can be generated that represents establishment of a physical asset that is fixed to a geolocation. A decentralized chain of custody for the transactable credit can be established in a distributed ledger. The decentralized chain of custody can include information describing the establishment of the physical asset, the geolocation of the physical asset, and transaction information for transactions involving the physical asset. Transactions involving the transactable credit can be authorized using the decentralized chain of custody, and transaction information for such transactions can also be stored in the distributed ledger as part of the decentralized chain of custody.

Electronic transfers of value may be secured via verification of locations of parties, and/or progressive trust building, while maintaining privacy of sensitive personal information of parties via separate communications by parties with a payment network server. Locations may be fixed geolocations, proximities, and/or positions relative to markers/beacons that are in motion. Transfers may be made from party to party, party to place and place to party, and/or party to a virtual point-of-sale at a place. Transferred items may be electronic funds in fiat and/or crypto currencies, Non-Fungible Tokens (NFTs)/data associated NFTs, electronic data, and/or securities/financial instruments, for example. Transactions may be multiparty and may comprise multiple exchanges of value.

Systems, methods, and computer-readable media provide automated identification techniques that associate at least two unique identifiers of one segment of a segmental multimode wireless flexible product to seamlessly and accurately bridge different identification methodologies to enable advanced real-time tracking of shipment location and status, and other such useful and advanced product and service offerings.

Systems and methods for operating a vending machine and/or kiosk. The methods comprise: detecting a presence of a person in a seat of the vending machine; obtaining a full or partial body heat map for the person that was created based on sensor data generated by at least one sensor of the vending machine or at least one sensor located in proximity to the vending machine (the full or partial heat map showing relative temperatures of different parts of a body of the person); selecting at least one vending service parameter for the vending machine using information obtained based on the full or partial body heat map; and causing the vending machine to provide the person with a vending service in accordance with the at least one vending service parameter that was selected.

Various techniques for facilitating communication with and across a network platform and one or more user computing devices are described. For example, these techniques may include (i) generating preference data based on capturing and analyzing user interactions with respect to a set of training photographs, (ii) generating, verifying, and processing search requests to allow users to identify other users and/or target objects on the network platform, and (iii) generating, verifying, and processing link requests to allow users to create links to or associations with other users and/or target objects on the network platform, among others.

Arrangements for transaction adapter control are provided. In some aspects, a user device may connect to a network in a current geographic location. The user computing device may detect that a change in geographic location has occurred based on the current geographic location. Responsive to detecting that the change in geographic location has occurred, a mobile transaction adapter associated with or unique to the current geographic location may be downloaded to the user computing device. The mobile transaction adapter may be a plug-in component to a mobile payment application on the user computing device. A request to process a transaction may be received via the mobile payment application on the user device. Upon receiving the request to process the transaction, the mobile transaction adapter may be activated and the request may be routed to the mobile transaction adapter. The requested transaction may then be processed via the mobile transaction adapter.

An example operation may include one or more of receiving, via a host platform of a digital wallet, a payment authorization request message for a payment transaction of the digital wallet from a payment gateway of an electronic payment network, verifying that the digital wallet has sufficient funds to satisfy an amount of the payment transaction and transmitting a payment authorization response to the payment gateway, pausing clearing and settling of the authorized payment transaction, generating an entry that represents the authorized payment transaction and storing the entry in a temporary storage structure of the host platform, executing a cryptocurrency transaction which exchanges cryptocurrency for an amount of fiat currency that satisfies the amount of the payment transaction, and canceling the authorized payment transaction and settling the payment transaction based on the amount of fiat currency received from the cryptocurrency transaction.
