> I hope this idea catches on

This already exists with Ethereum Name Service (ENS) https://ens.domains and Sign-in With Ethereum.

I have one of those. When everyone was changing their Twitter (display) names to *.eth I thought there might be a chance Twitter would use ENS for domain validated identities, so I grabbed one that matches a good .com I own.

The ENS stuff is cool, but I hope it doesn’t catch on unless they come up with a way to coexist with ICANN. I think multiple DNS roots would be a net negative no matter what.

ENS has DNS import via TXT Record verification proof, so the entire DNS tree can coexist in ENS trustlessly as long as future ENS-only TLDs are chosen wisely (seems simple: just use 0x80+ Unicode.) For example, try resolving my domain, "raffy.antistupid.com" in ENS.

I believe, the ENS registry only contains "eth" as an rogue node (also "[0-9a-f]{40}.addr.reverse" is used for wallet names). Recently, ".art" started offering tokenized names, where you get both DNS and ENS.
