Mlkut name system is going to be hard to explain... But I plan to use the existing analogies because they are appropriate;
1. Registrar; the entity registering a domain by making an onchain transaction.
2. Nameserver; the entity that the p2p network points to as the place where the corresponding records for a given name is served from, regardless of caching.

Your Registrar can be your Nameserver

You can be your own Registrar and your own Nameserver.

Your can backup the keys in case your Registrar dies.

You can rotate the keys with the cooperation of your Registrar to no longer need their liveness nor their honesty.

You can let your Nameserver hold the keys that sign DNS records, or you can take custody of these keys, and only rely on the Nameserver for hosting.

You choose how much do you care about your domain long term.
