Abstract: Autonomous devices and systems, methods, and program products for authorizing and performing autonomous devices transactions are disclosed. An autonomous device can be configured to generate a first hash value of a chain of hash values by applying a hash algorithm to first data including first new data and a first previous hash value of the chain of hash values, the first previous hash value computed by applying the hash algorithm to first previous data. The device can transmit to a transaction computer system the first hash value and the first new data. The device can generate and transmit to the transaction computer system a first signed electronic transaction request comprising first transaction data comprising a sending account identifier associated with the autonomous device, a destination account identifier, a transaction amount, and a timestamp. The device can digitally sign the transaction request using a private key of an asymmetric key pair.
