It maybe easier if you look into Handshake.org and get an idea. The root zone is replaced with block chain something or other, so some next level dns I would hasten a guess at. I’m just an onlooker who has purchased a handshake domain from porkbun.com recently, seeing this thread. I’ve been with Cloudflare for 6 years with hundreds of domains and every month there seems to be something else cutting edge that Cloudflare are doing. I thought this may align with the future. Maybe I’ll stick to reading rather than commenting. Best wishes.
