+## Simple Summary
+
+This document is about the details of the EOSIO namespaces and references for CAIP-2.
+
+## Abstract
+
+In CAIP-2 a general blockchain identification scheme is defined. This is the
+implementation of CAIP-2 for EOSIO.
+
+## Motivation
+
+See CAIP-2.
+
+## Specification
+
+### EOSIO Namespace
+
+The namespace "EOSIO" refers to the EOSIO open-source blockchain platform.
+
+#### Reference Definition
+
+The definition is delegated to the [EOSIO Transactions Protocol Documentation](https://developers.eos.io/welcome/v2.0/protocol/transactions_protocol/#32-sign-transaction), the [Chain API Plugin Documentation of the EOSIO Developers Manual](https://developers.eos.io/manuals/eos/latest/nodeos/plugins/chain_api_plugin/api-reference/index?query=chain%20id&page=1#operation/get_info) and the pull request that implemented its generation [Chain ID generation implementation pull request](https://github.com/EOSIO/eos/pull/3425). 
+The Chain ID is the SHA256 hash of the genesis state of the chain, and its represented as hexadecimal number of 64 digits
+
+## Rationale
+
+Blockchains in the "eosio" namespace are identified by their Chain ID as mentioned in the Reference Definition Section.
