Autonomous Agents launched on testnet.
An Autonomous Agent (AA) is a special address (account) on the ledger that acts according to a program associated with it. Its behavior is similar to that of a vending machine that receives coins and data entered on a keypad and in response, releases a cup of coffee, plays a song, or does whatever it was programmed to do.
