Keybase comes with social tools to verify identity. Would be pretty silly to see a military personnel profile in public view.

Good point, its been a while since I signed up and I forgot about the whole "verification" process. Thanks.

Put it in context, is it ever acceptable to have all your activity publicly logged? Keybase isn’t forward secure, so so disclosure of your keys later leads to complete availability of your cleartext.

According to https://keybase.io/blog/chat-apps-softer-than-tofu ephemeral messages are indeed forward secure, but normal messages are not, strictly speaking.

IMhO, Keybase is adequate to protect against spying from ISPs, Ad agencies, journalists, etc but doesn't offer resistance against a formidable foe like a state actor, but then neither does most of the devices on which Signal is run.

The US military has no need for Stellar.

Keybase is miserable to use currently and its only generally gotten worse. Was an early user and have continued to be disappointed.

I'd love to hear more as it doesn't match my experience. Among the oh-so-many IM apps I use, Keybase is my favorite as it's transparently cross platform, isn't tied to a phone [number], and the usability is good IMO.

DoD already has a PKI, it has no need for peer-to-peer identity/trust.
