Register domain DNS encoded name

[pikonha]

Refactor Request

Describe the Refactor Request

We need access to some properties that can't be gathered from the namehash of the domain. We need to have access to the DNS-encoded domain name instead.

Describe Preferred Solution

Change the register function to receive the DNS-encoded name instead of the namehash of it.

// current implementation
function register(bytes32 name, uint32 ttl)

// expected version
function register(bytes memory name, uint32 ttl)

We then need to store the following properties onto the database:

• [ ] name
• [ ] label name
• [ ] labelhash
• [ ] parent
• [ ] subdomains
