Not certain if this is antithetical to your business model, but seems prudent to create a version of this protocol for UTXO blockchains, specifically Bitcoin.
By doing this for Bitcoin, you’ll have also effectively knocked down:
Bitcoin Cash
Litecoin
Bitcoin SV
Monero (potentially)
If you agree with this suggestion, please upvote it. It could potentially be in everyone’s benefit to do so.
Well. Especially the Zilliqa blockchain could be useful since its gas fees are extremely low and also zilliqa itself offers decentralized domain names. :) And the token is already also in the metamask wallet. Could be good.
