Is this the same Privacy Pass that Cloudflare was using to allow clients to bypass CAPTCHAs? If so, this is a really neat application of that system; it never occurred to me that it could be used to anonymously authenticate to a paid service.

The cryptography privacy pass is based off [1] actually comes from Ecash[2] so we’ve gone full circle.

Yes, though Cloudflare has ended their privacy pass trial as far as I know.

I remember Safari as the only browser that implemented it natively, but I guess Orion has it now too.
