## 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.

## Backwards Compatibility
