 ## Introduction
 
-UCP aims at defining a data format, an interpretation of it and processing rules in order to build coherent free currency systems in a P2P environment. UCP is to be understood as an *abstract* protocol since it defines currency parameters and rules about them, but not their value which is implementation specific.

-This document describes UCP in a bottom-up logic, so you will find first the details of the protocol (data format) to end with general protocol requirements.

 ### Identity

-Issuing an identity is the act of creating a link between a *public key* and *an arbitrary identity*. In UCP, this link is done through the signature of an identity string by the private key corresponding to the public key. It is exactly like saying:
