PubKey is an ed25519 public key for handling Tendermint keys in SDK.
It's needed for Any serialization and SDK compatibility.
It must not be used in a non Tendermint key context because it doesn't implement
ADR-28. Nevertheless, you will like to use ed25519 in app user level
then you must create a new proto message and follow ADR-28 for Address construction.
