Open-Root sells TLDs and the customers manage them as they please. You can create your domain names freely, according to your needs, for projects, a brand, an event, your tribe. Once purchased the TLD belongs to you, without recurring costs.
In the ICANN root there is no billing for converting domain names into IP addresses, this is paid for by taxpayers because almost all root operators are financed by public funds. But you pay a provider for the creation, management and leasing of second level domain names.
In Open-Root, depending on one’s level of technical knowledge, one can manage extensions either using an Open Source software (e.g. DNS Manager) or through a provider that accepts open roots.
The conversion of extensions to IP addresses uses a name servers network.
As for roots, there is no reason to depend on a monopoly, and there may be multiple independent servers networks used by the roots.
The operation of these networks is a service provided to users who must normally cover operating costs.
Networks proposed by Open-Root offer flexible billing. Pricing will vary depending on the location of the customer and the geographical coverage of his usual access points.
It is a more logical and fairer business model which provides server operators with resources to maintain their equipment and invest in advanced techniques.
All host computers use a name server, i.e. a machine that converts a domain name into an IP address, just like a telephone directory (name+location = phone number). By default, all computers are configured with an ICANN name server.
To use its various extensions, the Open-Root client has only to indicate his name server and then he has access to the whole internet ... that is TLD registered in his root and in all other roots open to the public, plus all websites accessible through the ICANN root.
Note that users retain the choice of managing their extensions and can integrate them within their existing network.
The Internet was created to serve the open and costless dissemination and sharing of ideas and culture.
Registering a TLD in a root is certainly technical but takes a few minutes for a trained network manager. The only operating costs are servers converting TLDs to IP addresses.
For the record, in the ICANN, root name servers are managed by volunteers (university centers, research laboratories, government agencies, etc ...) where these costs are distributed and embedded in common expenses, usually paid as taxes by citizens.
