Each namespace covers a class of similar blockchains. Usually it describes an ecosystem or standard, such as e.g. cosmos or eip155. One namespace should refer to one resolution method to resolve the chain's reference.

A reference is a way to identify a blockchain within a given namespace. The semantics as well as the more granular syntax which are delegated to each namespace specification shall be defined in separate CAIPs describing resolution methods.

Each asset_namespace covers a class of similar assets. Usually, it describes an ecosystem or standard, such as e.g. slip44 or erc20. One asset_namespace should include as many assets as possible.

asset_reference is a way to identify an asset within a given asset_namespace.
