rns-artifacts - registrars
The Registrar is the contract that handles the domain issuing logic.
Any owner of an RNS node can determine the owner of a sub-node. A Registrar contract usually owns one or many nodes and issues sub-nodes under it.
- Subdomain Registrar: Allows anyone to create sub-nodes under a given and owned RNS node.
- Public Subdomain Registrar: Allows anyone to create sub-nodes under any delegated and owned RNS node.
- Price Subdomain Regitrar: Allows anyone who is whitelisted to create sub-nodes under a given RNS node and receive a token price for doing this.
