> This would allow changing of the TokenIdentifier between versions. The current serialization
is Writable. A simple way to achieve this would be to have a Proto object as the payload for
TokenIdentifiers, instead of individual fields.
> TokenIdentifier continues to implement Writable to work with the RPC layer - but the
payload itself is serialized using PB.
