A distributed ledger system configured to create, update and maintain at least one blockchain indicative of transactions performed by a network of users of the system, the system comprising a network of computing devices including a network of user nodes in communication with one another to participate in transactions and subsequently write the transactions to an associated blockchain, each node being associated with at least one processor and at least one computer-readable medium having recorded thereon instructions to be executed by the processor(s) to carry out one or more blockchain-related tasks for creating, updating and/or maintaining at least one associated blockchain of the system based on the transactions; and wherein the network of computing devices is operable to enable at least one ephemeral user node to join the network of computing devices to carry out the blockchain-related tasks in association with at least one blockchain during an active session of the ephemeral user node.

The systems and methods described herein provide for facilitating in-person payments at a transaction kiosk. First, the system provides an authentication interface for display at a network-enabled transaction kiosk. A user is authenticated at the kiosk via the authentication interface, and based on that authentication, the system detects a payment application and a payment request corresponding to the user, wherein the payment application is associated with a service provider and the payment request was created with the payment application. Next, the system identifies a user interface scheme associated with the payment application, and then updates the user interface for display at the transaction kiosk to match the user interface scheme, then initiates a blockchain payment based on the payment request.

A method for handoff includes: scanning an indirect token displayed on a guest device, where a guest has previously registered a payment instrument with a server, and associated the payment instrument with a plurality of indirect tokens, and the server has stored a payment token that associates the plurality of indirect tokens with the payment instrument in a database record along with a notification identifier; transmitting the ephemeral token to the server; simultaneously displaying details for a transaction, where the server has accessed the notification identifier to transmit a push notification to the guest device, and where the guest device is executing a proprietary application that allows for simultaneously displaying details for the transaction; and receiving notification from the server that the transaction is complete, where transaction completion data was entered via the guest device and transmitted to the server.

A method for transaction handoff includes: registering a payment instrument with a server, associating the payment instrument with indirect tokens, and storing a payment token that associates the indirect tokens with the payment instrument and a device identifier in a database record; via a device, receiving an indirect token from the server; via a point-of-sale (POS) terminal, entering the indirect token, and transmitting indirect token via the internet cloud to the server; via the server, using the payment token to access the device identifier and transmitting a push notification; upon acceptance of the push notification, executing an application on the device and simultaneously displaying transaction details on both the device and POS terminal; receiving completion data that is entered via the device and transmitting the completion data to the server; and completing the transaction at the server and notifying the POS terminal and the device that the transaction is complete.

A server includes: a database that registers a payment instrument, associates the instrument with indirect tokens, and stores a payment token that associates the indirect tokens with the instrument in a record along with an identifier for a device; a communication circuit, that receives transaction details from a POS terminal, and receives the one of the indirect tokens from the POS terminal; and a code segment, that employs the payment token to access the identifier in the record, directs the communication circuit to send a push notification, and, upon execution of the proprietary application on the device, directs the communication circuit to transmit transaction details to the POS terminal and the device, receives transaction data from the device, completes the transaction, and directs the communication circuit to notify the POS terminal that the transaction is complete.

System and methods for improving electronic currency and distributed ledger technologies to solve price and data manipulation, control vulnerabilities, off-chain dependencies and circulation problems of electronic currency is disclosed. More particularly, the present disclosure provides technical improvements to the substantiation, issuance and circulation of electronic currency including but not limited to, issuing electronic currency at the issuer's will in single blocks of varying amounts and attributes to be circulated, transferred and used for payment on a distributed ledger network. The electronic currency of an aspect of the present disclosure are a representation of financial instruments of the issuer with legally binding obligations and rights enforceable by at least one legal jurisdiction tokenized into units of electronic currency and used to make payments. Disclosed aspects of the present disclosure provide technical solutions to price discovery and stability in relation to fiat currency; privacy protection in payment and transfer transactions; a closed loop system for the on-chain settlement of the electronic currency and financial instruments, and solves security vulnerabilities for blockchain and distribute ledger technologies including data and market manipulation, 51% control attacks and dependencies of trusted players and off-chain transactions.

Various embodiments are directed to processing conversions of digital assets to other digital assets. An example method includes determining a source exchange rate for a source digital asset and a fiat currency, determining a target exchange rate for a target digital asset and a fiat currency, and generating an aggregated conversion rate for the source digital asset and the target digital asset using the source exchange rate and the target exchange rate. The method further includes executing a digital asset conversion, which includes causing source digital asset units to be debited from a source digital asset user account and causing target digital asset units to be credited to a target digital asset user account, and subsequently executing fiat currency transactions (e.g., settlements) with a first digital asset exchange system associated with the source digital asset and a second digital asset exchange system associated with the target digital asset.

A system and method for providing a litigation funding platform and exchange can include a user device that generates a litigation event, an initial litigation product offering (ILO) computer system, and a digital exchange system. The ILO system can receive the litigation event, generate (i) a litigation product contract, (ii) a master product key pair for the litigation event that includes a public and private key, and (iii) a freeze rule. The ILO system can also provide an initial offering of such tokens, receive requests to purchase the tokens, generate a plurality of the tokens, and generate a token ledger. The digital exchange system can match digital trades of the litigation product tokens using the token ledger. The digital exchange system can permit or block the trade based at least in part on whether a freeze event has been validated and invoked for the particular litigation product token.
