Wow, that’s a great idea! I loved keybase back in the day and really thought it solved a real world problem in a unique and interesting way. Then Zoom bought it (for some reason) and left it to rot.
A shame really, because Keybase was kind of unique in the way the facilitated social proof of identity tied to cryptographic keys. A shame though that they never found a really sustainable business model. When they turned to crypto currency towards the end of their independent run I knew it probably wouldn't last.
I just deleted it as I noticed it was responsible of about 30% of active cpu (and battery drain) usage on my mac, while being logged out due to inactivity. Honestly: I never particularly liked it, and I could not feel the concept especially tempting, just went with the team.
