# Autonomous Agents

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.

## Oscript — the language of autonomous agents

Autonomous Agents are written in Oscript — a new programming language developed specifically for this purpose. The language is very simple and any developer who has experience in curly-brace languages such as JavaScript, PHP, Java, C/C++, etc should not have any difficulty learning it.

Some of the features of the language:

* convenient access to variables that describe the state of the ledger and the triggering (requesting, activating) transaction received. That’s what makes the language domain-specific. In particular, the following variables are available:
* amounts received in the triggering transaction;
* data received in the triggering transaction;
* who sent the triggering transaction;
* state variables of the current and other AAs;
* data feeds;
* attestations;
* balances of this and other AAs;
* information about assets;
* arithmetic operations;
* logical operations (AND, OR, etc);
* comparisons;
* concatenations;
* some math functions;
* some cryptography functions for calculating hashes and validating signatures created off-chain;
* branching with if/else;
* no loops (just iteration methods for objects and arrays);
* no recursive functions;
* scalar and object data types;
* generation of deterministic pseudo-random number from seed.
