Currently supports Session, Wallet and Lokinet registrations. Lokinet registrations can be for 1, 2, 5, or 10 years by specifying a type value of "lokinet", "lokinet_2y", "lokinet_5y", "lokinet_10y". Session and Wallet registrations do not expire.

The owner of the ONS entry (by default, the purchasing wallet) will be permitted to submit ONS update transactions to the Loki blockchain (for example to update a Session pubkey or the target Lokinet address). You may change the primary owner or add a backup owner in the registration and can change them later with update transactions. Owner addresses can be either Loki wallets, or generic ed25519 pubkeys (for advanced uses).

When specifying owners, either a wallet (sub)address or standard ed25519 public key is supported per mapping. Updating the value that a name maps to requires one of the owners to sign the update transaction. For wallets, this is signed using the (sub)address's spend key.
