I see. That MO makes a bit more sense then, though is it not then limited to just Keybase.io and will no longer work if something happens to this service? Or more importantly, is there a way to make this distributed?
All public server-side data is available as a dump (https://keybase.io/__/api-docs/1.0#call-dump-all). Private data like encrypted public keys and password hashes we of course will keep under wraps.
We don't have immediate plans to make the system distributed, but if someone did it, we'd find it very cool. It's just too much for us to do right now.
