Abstract
A payment network is operated with a blockchain-based ledger. In one embodiment, a request is prepared to complete a transaction from an account associated with a payer digital wallet for entry on a blockchain. The request includes an amount and a payee identifier associated with a payee digital wallet. The request is sent to the blockchain and approved. A balance of the payer digital wallet and a balance of the payee digital wallet are adjusted in response to approval of the request to complete the transaction by at least writing a portion of data associated with the transaction comprising the amount and the payee identifier to the blockchain. A reputation ledger associated with the account is recorded in the blockchain in association with the transaction. The reputation ledger includes at least one reputation score associated with at least one previous transaction conducted by the account.
