USING AN INTERNAL LEDGER WITH BLOCKCHAIN TRANSACTIONS

Resumen de: US2024289773A1

Systems, methods, and computer-readable media disclosed herein relate to reducing computation and computing resources for certain blockchain related transactions. Specifically, software algorithms and architecture allow some transactions to avoid the need for recordation on a blockchain, which can be computationally expensive both for a requesting device and for various nodes on the blockchain. Thus, a computer system may receive indications of incoming transactions transferring digital assets to particular user accounts, and in response to requests from user accounts, the computer system facilitates one or more internal transactions between those accounts. In response to a request from a particular internal user account, the computer system may perform an outgoing transaction transferring one or more digital assets to an external user account from one or more internal user accounts. The incoming transactions and outgoing transaction are recorded on the blockchain, but the internal transactions are recorded on an internal ledger rather than the blockchain, saving computational power and improving computer operations.

CRYPTO MANAGEMENT

Resumen de: US2024289754A1

A consumer links a cryptocurrency wallet to their loyalty account and creates a profile that includes a default fiat currency amount to add to transaction totals during transactions at a terminals. During a transaction, the wallet and profile are obtained using the loyalty account of a registered consumer. When the consumer selects an option to pay for their transaction, an overlaid screen is presented to the consumer on the display of the terminal requesting that the consumer confirm the fiat currency amount. When the consumer confirms, the transaction total for the transaction is rounded up by the fiat currency amount. A background workflow is automatically initiated after payment is confirmed on behalf of the user. The workflow uses the fiat currency amount to purchase and transfer an equivalent amount of cryptocurrency into the consumer's wallet over the blockchain.
