+# LIP9 Namespace
+
+This document is about the details of the Lisk namespace as defined by LIP-9,
+including Lisk Mainnet and Testnet, forks and side chains.
+
+## Syntax
+
+The namespace `lip9` refers to Lisk namespace as defined above.
+
+## Governance
+
+The Lisk namespace is governed by the Lisk Improvement Proposal [LIP][] system.
+
+## References
+
+- [LIP-9] - The Lisk Improvement Proposal that defined chain IDs for making
+  transactions resistant to cross-chain and cross-fork replay.

+status: Draft
+type: Standard

+requires: CAIP-2
+supersedes: CAIP-6

+
+# CAIP-2
+
+*For context, see the [CAIP-2][] specification.*
+
+## Rationale
+
+In CAIP-2 a general blockchain identification scheme is defined. This is the
+implementation of CAIP-2 for the Lisk ecosystem as defined in [LIP-9][].
+
+## Semantics
+
+The definition is delegated to LIP9. 
+
+## Syntax
+
+The reference format is a 16 character string extracted from the first 16
+characters of the network identifier defined in LIP9 (a 64-character SHA256 hash
+in lowercase hex).
+
+### Backwards Compatibility
+
+LIP-9 introduced a hard fork, but no cross-fork/cross-chain replay protection
+(or other validating chain identification scheme) predates it.
+
+## Test Cases
+
+This is a list of manually composed examples
+
+```
+# Lisk Mainnet (https://github.com/LiskHQ/lips/blob/master/proposals/lip-0009.md#appendix-example)

+# Lisk Testnet (echo -n "da3ed6a45429278bac2666961289ca17ad86595d33b31037615d4b8e8f158bbaLisk" | sha256sum | head -c 16)
