Unfortunately this only applies to people under GDPR. Currently we (non GDPR) can pay an extra dollar to hide WHOIS information, or maybe some registrars have it built into their price. Not sure if the WHOIS censorship was a result of the GDPR, or they improved upon other stuff too that us who don’t fall under GDPR miss out on. You do still need to put in a fair bit of information to the registrar most of the time though unfortunately.

I know Njalla exists, but they’re not a registrar, they’re a middleman between you and the registrar. Although it is far more expensive than most registrars, I believe they buy the domain outright. They accept a wide variety of payment options including various cryptocurrencies. But yeah, I don’t know of anything else, they are only registrars but I would take a libre registrar in a heartbeat if it was priced similar and was solid.
