What is Keybase used for?
Keybase allows users to prove a link between certain online identities (such as a Twitter or Reddit account) and their encryption keys. Instead of using a system such as OAuth, identities are proven by posting a signed statement as the account a user wishes to prove ownership of.
Is Keybase free?
Keybase is a new and free security app for mobile phones and computers. For the geeks among us: it's open source and powered by public-key cryptography. Keybase is for anyone. Imagine a Slack for the whole world, except end-to-end encrypted across all your devices.

Only you and your intended recipients can read what you share. Not even Keybase can access it.
