A method includes implementing a distributed digital ledger through a crypto-transactional platform, processing, via the crypto-transactional platform, a first crypto transaction through a payment card, and additionally processing, via the crypto-transactional platform, a second non-crypto transaction through the payment card. The distributed digital ledger is a growing set of records linked through cryptography. As part of processing the first crypto transaction and the second non-crypto transaction through the payment card via the crypto-transactional platform, the method also includes handling security of both the first crypto transaction and the second non-crypto transaction through the payment card via the distributed digital ledger.

A method and apparatus that receive blockchain transaction data from a blockchain ledger to a transaction database, receive intelligence labels from a blockchain ecosystem intelligence database, select a blockchain transaction flow comprising blockchain transactions associated with a digital account source address, digital account intermediate addresses, a digital account destination address, and intermediate transactions, receive input trace parameters, where the input trace parameters include at least one of an objective directional setting, a tracing constraint, and a transaction filter, the transaction filter based on the transaction timestamps and the digital assets transferred, apply the intelligence labels to the digital account source address, the digital account intermediate addresses, and the digital account destination address, apply an artificial intelligence graph search algorithm to the blockchain transaction flow based on the input trace parameters, and generate a report including tracing destination summary statistics of the auto-traced path.

A processor-implemented method is disclosed. The method includes: receiving, via a terminal device, input of a first password during a card session that begins when a value transfer card is inserted into the terminal device, the value transfer card being associated with a plurality of passwords; verifying that the first password is a valid password associated with the value transfer card; identifying at least one card control setting associated with the first password, the at least one card control setting being a setting that is not associated with another one of the plurality of passwords; and processing a transaction initiated at the terminal device based on the identified at least one card control setting.

A method for verifying an identity of an individual as a first party via a first party system by a second party system comprises: sending a request for identification information of the first party; receiving first party information associated with a mobile identification credential (MIC) which the first party system received from an authorizing party system (APS) before the second party system sends the request for identification information of the first party to the first party system, the first party having consented to release the first party information to the second party system, and the first party information having been verified by the APS before the APS sends the MIC to the first party system; using the verified first party information associated with the MIC to verify or not verify an identity of the first party; verifying the identity of the first party before providing services to the first party.

Systems, methods, apparatuses, and computer-readable media for secure generation of one-time passcodes using a contactless card. In one example, an operating system (OS) of a device may receive a uniform resource locator (URL) and a cryptogram from a contactless card. The OS may launch an application associated with the URL. The application may transmit the cryptogram to an authentication server. The application may receive a decryption result from the authentication server indicating the authentication server decrypted the cryptogram. Based on the decryption result, the application may request an OTP. The processor may receive an OTP from an OTP generator. The application may receive an input value and compare the input value to a copy of the OTP. The application may determine that the comparison results in a match, and display, based on the determination that the comparison results in the match, one or more attributes of the account.

A method and system for reducing carbon footprint. The process includes the step of receiving a plurality of carbon offset products available for purchase, maintaining an inventory of the plurality of carbon offset products. The process further include the step of displaying the plurality of carbon offset products along with a respective carbon credit value to a user on a mobile device, receiving a request for purchase from the user, verifying the selected at least one carbon offset product provenance by validating the metadata mapped with the at least one carbon offset product in the blockchain ledger, confirming an order of purchase of the selected carbon offset product if the at least one carbon offset product provenance is validated. The process further includes the step of generating a digital certificate based on the confirmed order, the digital certificate comprising the carbon credit value associated with the purchased carbon offset product.

Provided is a method including receiving, by a user device, a request from an identity service to approve communicating a user proof-of-identity to a relying party. A user of the user device is prompted to request a one-time transaction identifier based on the request. Based on a first input from the user, the user device requests the one one-time transaction identifier from the identity service. In response to the request for the one-time transaction identifier, the user device receives the one-time transaction identifier from the identity server and displays the one-time transaction identifier on a first user device screen. The user inputs the one-time transaction identifier on a second user device screen and the user device communicates the one-time transaction identifier to the identity service. In response to receiving the at least one inputted one-time transaction identifier, the relying party determines whether to approve or deny a transaction.

A method to enable transactions comprising transmitting, by a vendor server, a request message to the e-commerce system for a token. Receiving a token in response to the request message. Generating an offer message including a mailto hyperlink, wherein the offer message is an email message including a mailto hyperlink is configured to generate an email reply message include the token. Transmitting the offer message to an email address associated with the customer. Receiving a response message from the e-commerce system, the response message including transaction details that confirm the token was validated by the e-commerce system. Transmitting a payment processing request message to a payment processor, wherein the payment processing request is based on the transaction details. Receiving a notification from the payment processor, that payment processing has been completed. Transmitting an email message to the email address of the customer, that payment has been processed.

Implementations of the present disclosure provide techniques to improve security in blockchain networks. In some implementations, a linking request is received from a node. The node requests to be linked to a blockchain network. The linking request includes a digital code. One or more consensus verification messages are received from one or more blockchain nodes of the blockchain network. Each consensus verification message indicates whether a respective blockchain node approves or denies the linking request. A consensus verification result is determined based on the one or more consensus verification messages. In response to determining that the linking request is approved by the one or more blockchain nodes, the digital code is stored into the blockchain network as a digital certificate of the node.

Transaction-enabled methods for providing provable access to a distributed ledger with a tokenized instruction set for semiconductor fabrication processes are described. A method may include accessing a distributed ledger including an instruction set for a semiconductor fabrication process and tokenizing the instruction set. The method may further include interpreting an instruction set access request and, in response to the access request, providing a provable access to the instruction set. The method may further include providing commands to a production tool of the semiconductor fabrication process in response to the instruction set access request, and recording the transaction on the distributed ledger.
