Systems and methods for blockchain based payment networks

Abstract:

A system for operating a payment network with a blockchain-based ledger may prepare a request to complete a transaction from an account associated with a payer digital wallet for entry on the blockchain. The request may include an amount and payee address associated with a payee digital wallet. The system may also send the request to the blockchain using a blockchain interface. The system may approve or decline the request. The system may further adjust a balance of the payer a balance of the payee to reflect approval of the request. The adjustment may include writing the transaction to the blockchain.
