To conduct a payment transaction at a merchant's point of sale using a mobile device, the mobile device initiates an authenticated communication session with a payment agent. The payment agent is an entity responsible for facilitating a payment transaction between the merchant and purchaser via their respective financial institutions. During the authenticated communication session, response to an input indicating the user of the mobile device wishes to make a payment, the mobile device generates a unique payment key that is based on at least one unique data of the mobile device. The mobile device transmits the payment key to the payment agent, and then transfers a copy of the payment key to the point of sale system. The merchant's payment system that transmits the payment key to the payment agent in a transaction request. The payment agent then verifies that the received payment key is the same as they received from the mobile device, and that the authenticated communication session is still valid, and then approves the transaction.

Systems and methods for complex process flow approval using distributed ledgers are disclosed. The method may include generating a process initiation message based on input from a second service provider or a user. The method may include recording the process initiation message on a first distributed ledger. The method may include monitoring the first distributed ledger for an indication of an approval event. The method may include generating a settlement event based on the indication of the approval event. The method may include recording the settlement event on the first distributed ledger. The method may include communicating a settlement event message to a second distributed ledger. The method may include generating a virtual payment instrument associated with the settlement event message, the indication of the approval event, and the process initiation message.

Aspects of the disclosure relate to isolating and reinstating nodes in a distributed ledger using proof of innocence. In some embodiments, a first plug-in embedded with the blockchain network may monitor consumer-initiated transactions submitted to an enterprise organization node to determine the legitimacy of each consumer-initiated transaction. The first plug-in may identify consumer-initiated transactions associated with malicious activity and may flag the consumer node for further analysis. A second plug-in may identify and analyze the consumer-initiated transactions associated with the consumer node to determine a proof of innocence value associated with the consumer node. The first plug-in may isolate the consumer node from the distributed ledger if the proof of innocence value exceeds a proof of innocence threshold. Alternatively, the first plug-in may permit the consumer node to remain within the distributed ledger if the proof of innocence value falls below the proof of innocence threshold.

Systems as described herein generate an outstanding check alert. An alert generating server may receive transaction records associated with a plurality of checking accounts. The alert generating server may user a first machine learning classifier to determine a transaction pattern indicating a merchant has failed to process outstanding checks for a period of time. The alert generating server may receive sequential check information comprising at least one missing check number associated with a particular checking account. The alert generating server may user a second machine learning classifier to determine at least one outstanding check associated with the particular checking account. The alert generating server may send an alert indicating the at least one outstanding check to a user device.

A computer-based system collects data associated with a user activity. The data is transmitted from an app running on a computing device with a user account authenticated by the computer-based system. A carbon footprint of the user activity is calculated based on the data associated with the user activity. The system calculates a proof of environmental impact in response to a function of the carbon footprint and a baseline value. An amount of cryptocurrency is generated based on the proof of environmental impact by writing a transaction for the amount of cryptocurrency to a blockchain in response to proof of environmental impact. The amount of cryptocurrency is assigned to the user account authenticated with the computer-based system.

A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. The cryptographic token is written to a blockchain using a smart contract that is configured to enable a transaction associated with the token in response to two or more of: a signature by the encryption chip, a signature by the owner of the diamond asset, and a validation of a visual layout of the diamond asset.

A system and method for verifying account ownership using verified deposits. An ACH verification platform may recognize or detect a verification process involving microdeposits. A verification platform may receive and store user login, initiate the deposits, and monitor the user's account to verify that posting of the deposits was successful. In embodiments, a dedicated web form or portal may be provided for receiving verification information.

A system, method, apparatus, and computer program product for interactively broadcasting value via a sound, a Wi-Fi, a Bluetooth, an email, a messaging, an RFID, or an NFC to incentivize direct consumer engagement. The system produces verifiable data on customer preferences, habits, and purchasing while using secure digital cryptographic technology to convey an item of value. The system is configured to transact a digital token normally carried on a blockchain leger in an off-ledger condition. The digital token is embedded with a media content. A mobile computing device having a representation of a digital wallet is configured to detect the digital token, decode the digital token and is transfer the digital token back to the blockchain ledger. When validated by the blockchain ledger, the digital token is transacted to a digital wallet on the blockchain ledger.

Systems and methods for reducing latency in transactions are described herein. In an embodiment, an application edge acts as a system of record for an application. When a client computing device sends a request to perform a transaction to the application, the application edge receives the request and, without forwarding the request to a backend computing network, searches a transaction datastore stored at the application edge for the account balance and responds to the client computing device with the account balance. The client computing device then determines that a transaction can be performed and sends a request to perform the transaction to the application. The application edge passes this request to the backend computing network which performs the requested transaction. The application edge then uses a webhook infrastructure to update each transaction datastore stored at the application edge.
