A method for enabling real-time authorization of a transaction with pooled equity includes: receiving a transaction request message, the transaction request message including at least a public key of a cryptographic key pair and a transacting currency amount; verifying a balance of a cryptographic currency for a first blockchain wallet associated with the cryptographic key pair on a blockchain using at least the public key, where at least a portion of the balance is locked in a currency pool; generating a smart contract, the smart contract configured to initiate a first blockchain transaction on the blockchain for transfer of the transacting currency amount from a second blockchain wallet to a destination address, where the second blockchain wallet is different from the first blockchain wallet; and transmitting the generated smart contract to a node in a blockchain network associated with the blockchain for publishing to the blockchain.

Method and system for authorization for cryptocurrency on distributed ledger

A method for performing dual verification to combine a non-fungible token (NFT) with a digital payment instrument includes: receiving a first set of authentication credentials and a second set of authentication credentials, the first including a transaction account identifier, and the second set including an NFT identifier and a public key of a cryptographic key pair; performing a first verification process using the first set of authentication credentials based on at least a comparison of the first set of authentication credentials with data associated with a transaction account identified using the transaction account identifier; performing a second verification process using at least the second set of authentication credentials based on validation of a digital signature using the public key, the digital signature being identified using the NFT identifier; and transmitting a result of the first verification process and the second verification process to a computing device.

Method and system of associating custom card designs with non-fungible tokens

A method for facilitating benefit disbursements through the use of tokens and blockchain includes: receiving beneficiary information from a first computing system, the beneficiary information including a beneficiary identifier; storing a blockchain data entry, the blockchain data entry including a disbursement token associated with the beneficiary information and a recipient value generated using a public key of a cryptographic key pair; receiving a redemption message from a second computing system, the redemption message including the disbursement token, a digital signature generated using a private key of the cryptographic key pair, transaction account data, and a redemption amount; validating the digital signature using the public key of the cryptographic key pair; and transmitting a transfer message to the first computing system, the transfer message including the transaction account data and the redemption amount.
