If this is using blockchain to login, then does this mean one will have to pay gas fees for operations with the identities? Is it going to be "pay for each login"? or "pay to enroll to a new website"?<p>If this not writing to blockchain, then how is this different from WebAuthn? I assume you can use Trezor instead of Yubikey, but is this going to be enough to make this protocol popular?<p>Or perhaps I am misunderstanding something, and this is just designed for websites with deal with Ethereum and not as a replaced to "Login With Facebook" and so on?
I'm not bullish on crypto, but this is definitely a welcome development in the distributed identity space after Keybase's unfortunate acquisition by Zoom.
