A method for automatic initiation of a blockchain transaction with a pre-approved recipient includes: receiving at least a recipient identifier and a transaction amount; performing a validation process to validate that (i) the recipient identifier is pre-approved by a user of the computing device for blockchain transactions, and (ii) the transaction amount is beneath a predetermined amount limit for blockchain transactions; generating a new blockchain transaction including at least the recipient identifier, the transaction amount, and one or more source addresses; digitally signing the new blockchain transaction using a private key of a first cryptographic key pair stored in a memory of the computing device; and transmitting the digitally signed new blockchain transaction to a blockchain node in a blockchain network.

A system and method for processing digital payments using a smart chip payment acceptance module associated with an Internet of Things (IoT) or vending device via a virtual EMV terminal process for cloud-based digital payment transactions. A short-range communication channel is provided between a mobile user device and the payment acceptance module. The mobile user device includes a wallet application with an integrated merchant application used to create a payment transaction. An unlock device enables digital secure remote payments (DSRP). A smart chip server connected to a payment gateway can generate an encrypted proof of payment (POP) message indicating completion of the payment transaction. The user can complete the payment transaction using the integrated wallet application within the user device in an online or offline mode of the vend device for seamless interaction with the system by a new user as well as improved flexibility for merchants and consumers.

A method for assisting wallet providers in regulatory compliance for blockchain transactions includes: receiving, by a receiver of a processing server, a new blockchain transaction from a first computing device, the new blockchain including at least a destination address associated with a blockchain wallet as a recipient for the new blockchain transaction; generating, by a processor of the processing server, a reference identifier for the new blockchain transaction; identifying, by the processor of the processing server, a profile for the blockchain wallet based on the destination address; transmitting, by a transmitter of the processing server, the reference identifier to the first computing device; and transmitting, by the transmitter of the processing server, a notification message to a second computing device, the notification message including at least the reference identifier and data associated with the blockchain wallet.

Method and system for regulation of blockchain transactions

A method for carrying out a cryptocurrency blockchain transaction through an integrated circuit payment card using a multi-signature blockchain wallet includes: storing, in an integrated circuit of a payment card, a first private key of a first cryptographic key pair and a transaction account number; receiving, by the integrated circuit, a blockchain transaction from a point of sale device, the blockchain transaction including unspent transaction outputs, destination addresses, a cryptocurrency amount for each destination address, and a first digital signature generated using a second private key of a second cryptographic key pair; digitally signing, by the integrated circuit, the blockchain transaction using the first private key to generate a second digital signature; and transmitting, by the integrated circuit, the digitally signed blockchain transaction including the first digital signature and the second digital signature to the point of sale device.

A method for acceptance of blockchain payment at a traditional point of sale device direct to a merchant includes: receiving an authorization request for a fiat payment transaction including a transaction account number, transaction amount, and merchant identifier; identifying blockchain payment acceptance for a transaction account associated with the transaction account number; transmitting an address request to an exchange server including the merchant identifier; receiving a destination address associated with the merchant identifier for a blockchain network from the exchange server; transmitting a new blockchain transaction to a blockchain node in the blockchain network including the destination address and a cryptocurrency amount based on the transaction amount; and transmitting an authorization response for the fiat payment transaction to a payment network for routing to a point of sale device, the authorization response including an indication that clearance and settlement of the fiat payment transaction is not required.

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.

The present disclosure generally relates to controlling operation of service devices. A payment network server receives, from a merchant aggregator, an operation request from a user for operation of one or more service of the devices associated with the merchant aggregator, the operation request comprising identification data of each service device, an operation mode selected by the user for each service device, and a payment token of the user; identifies, based on the identification data of each service device, a device server communicatively connected with the service device; communicates, to the respective device servers, operation instructions for controlling access to the service devices, the instructions comprising activating the service devices, thereby permitting the user to access the service devices; determining a payment amount for operation of the service devices requested in the operation request based at least on the selected operation modes; and processing a payment transaction for paying the payment amount to the merchant aggregator using the payment token.

Electronic system and computerized method for controlling operation of service devices

A method for validation of identity of a user during a digital payment process comprises: receiving a user identifier; determining, based on the user identifier, that the user is enrolled for biometric authentication; transmitting, to a mobile device associated with the user identifier, a push notification, said push notification causing an authenticator application executing on the mobile device to initiate a biometric authentication process; receiving a result of said biometric authentication process; and transmitting authentication data, based on said result, to a transaction initiation system to trigger completion of the digital payment process.
