A system and method for preventing the double-spending of digital currency that transfers between multiple DLT networks. The system and method includes creating, based on a unit of fiat currency, a first digital currency of a first type on a first DLT network and a second digital currency of a second type on a second DLT network. Each of the first digital currency and the second digital currency simultaneously represent a value associated with the unit of fiat currency. The system and method includes detecting a transaction request to transfer the first digital currency from the first DLT network to the second DLT network. The system and method include locking, responsive to detecting the transaction request, the first digital currency onto the first DLT network to prevent a transfer of the first digital currency from the first DLT network to another DLT network responsive to a subsequent transaction request.

The invention relates to a card, in particular a chip card, including a computing unit for managing electronic coin data records, the electronic coin data records being issued by a central entity, and a card body with visible data and at least one visible feature. The central entity is at the same time the issuer or administrator of a series of banknotes and the at least one visible feature identifies the card as part of the series of banknotes to an observer. In addition, a method for producing such a card is also proposed.

A digital content management system includes a digital content information reception unit configured to receive digital content and the number of pieces of non-fungible token (NFT) content to be generated based on the digital content, a digital content conversion unit configured to generate a number of pieces of NFT digital content equal to the number of pieces of NFT content by converting the digital content, an NFT generation unit configured to generate an NFT based on a blockchain for each of the generated pieces of NFT digital content, and a checking unit configured to check an NFT generated for the NFT digital content to be played back when playing back one of the generated pieces of NFT digital content.

What is disclosed is a system for accessing the value of real property. The system includes a real property; a computer readable medium for storing a computer program; a graphical user interface for viewing the real property and a value of the real property; a blockchain ledger, that records and stores information and transactions; cryptocurrency coins; a governing entity with authority over the possession; an issuing entity, which creates and issues cryptocurrency. The computer program communicates with the blockchain, and the computer program and blockchain are adapted to communicate with the governing entity and the issuing entity. Once the property has been entered into the program the governing entity authorizes the issuing entity to create cryptocurrency coins and issue those cryptocurrency coins to the owner of the possession. The computer program ensures that the cryptocurrency coins are recorded in the blockchain ledger.

Provided are a method and system for payment when a network is blocked. A method of providing a remittance service performed by a first device, the method including requesting a financial institution system to issue a block key layer for at least a portion of an amount of money retained by a user of the first device, receiving the block key layer from the financial institution system in response to the request, receiving, from a second device, remittance request data for an amount of remittance, obtaining, from the received block key layer, a block key layer corresponding to the amount of remittance, and transmitting, to the second device, a file for the block key layer corresponding to the amount of remittance.

A device includes one or more NFC chips that are preprogrammed to provide a payee's identification and information for launching any of several P2P cashless payment applications to which the payee is subscribed, to a mobile phone of a payor. When a mobile device of a payor is brought to the vicinity of an NFC chip of the device, the mobile device launches a corresponding P2P cashless payment application. The P2P cashless payment application shows the payee's information and the payor may proceed to make a payment to the payee. The device may include an NFC chip that is preprogrammed to provide the payee's identification and the information for launching a single application on the mobile device of the payor to display the P2P cashless payment applications to which the payee is subscribed. The payor may then proceed to make a payment to the payee using the payor's mobile device.

A method for management of financial transactions associated with a funding agreement may include: receiving, at the award information management system and from an awarding organization, details for a funding award comprising an identification of an award recipient, an award amount, and a condition on the use of the award; notifying an award drawdown management system of the award details; identifying a plurality of participating financial institutions to the award recipient; receiving a registration of an account at one of the financial institutions for receiving drawdown funds; communicating an amount of the payment to the fund reporting and analysis system; receiving transaction details from the financial institution having the award recipient's registered account; and providing reports of all transactions in the registered account and any and all optional card accounts with detailed analysis of part transaction, current balances and predictions of future drawdown requests.

The disclosed embodiments relate to implementation of an electronic framework, also referred to as a protocol or architecture, for electronically achieving, recording and implementing, via an electronic communications network, consensus among participants for the definition, implementation and operation of an electronic transaction processing system as a precursor to the operation of that transaction processing system in processing transactions according to the consensus among the participants. The disclosed consensus framework provides a system and protocol by which new electronic transaction processing systems may be developed and implemented among participants via an electronic negotiation and implementation of the operational rules therefore. The disclosed embodiments eliminate the need for out of band consensus negotiations and provide flexibility for participants to negotiate acceptable operational rules which can support complex transactional processes in an electronic environment.

Aspects described herein include using proximity technology such as beacon devices or geofences to detect physical presence at a physical location. Presence information may be generated and included in a non-fungible token (NFT). The NFT may be provided to a digital wallet. The identity of an individual associated with the digital wallet may be authenticated. A distributed ledger may record the transaction that provides the NFT to the digital wallet.

A distributed ledger system may include a first distributed ledger node associated with a first participant bank that maintains a first participant bank deposit account on a blockchain-based distributed ledger in a distributed ledger network; a second distributed ledger node associated with a second participant bank that maintains a second participant bank deposit account on the blockchain-based distributed ledger; and a third distributed ledger node associated with a liquidity provider that maintains a liquidity provider deposit account on the blockchain-based distributed ledger. A consensus algorithm operates on the distributed ledger nodes and updates the blockchain-based distributed ledger in which multiple copies of the blockchain-based distributed ledger across the distributed ledger nodes, and transactions involving the first participant bank deposit account, the second participant bank deposit account, and/or the liquidity provider deposit account are added to a block to the blockchain-based distributed ledger.
