Hardware requirments for tld registrar. Non icann dnssec and dane supported

I am trying to figure out requirments for a tld registrar. I have the names. Customers have the access. Just missing the skillset and hardware. Icann is not accepting these names at the moment,however icann is not a requirement. The domains do work as they have an alternate dns root zone. I know for name servers i should have 2 seperate geolocations.

Thinking a basic lamp server could also serve the glue records

I need to enable dnssec and dane security for the tld and all subdomains should support thier own ds and tlsa records. (Or is that dns level?)

what would I need for hardware and software.

This is already being done with etherum as a registrar but i am looking fora server based solution

Just to be clear. I am a noob. Thank you.
