Methods and systems are disclosed for transactions with a private digital currency. The private e-currency may be backed by a financial institution, managed using a blockchain, and only available for transactions with members of a network associated with the financial institution. The members may include mobile wallets, merchants and ATM's. A mobile wallet may register with the network and receive an amount of the private e-currency from the financial institution. The mobile wallet may establish a connection with a payment recipient such as another wallet, an ATM or a merchant, and receive a payee address. The mobile wallet may send a transaction request to the blockchain for payment to the payee address of a payment amount of the private e-currency, so that the payment recipient can, using a blockchain, confirm or deny the transaction request.
