+## Simple Summary
+
+This document is about the details of the Polkadot namespace and reference for CAIP-2.
+
+## Abstract
+
+In CAIP-2 a general blockchain identification scheme is defined. This is the
+implementation of CAIP-2 for Polkadot chains.
+
+## Motivation
+
+See CAIP-2.
+
+## Specification
+
+### Polkadot Namespace
+
+The namespace is called "polkadot" to refer to Polkadot-like chains.
+
+#### Reference Definition
+
+The definition for this namespace will use the `genesis-hash` as an indentifier for different Polkadot chains.
+
+## Rationale
+
+The rationale behind the use of genesis hash stems from its usage in the Polkadot architecture in network and consensus.
