This is my Keybase page. Here's what Keybase says about itself: "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. Or a Team Dropbox where the server can't leak your files or be hacked." See also (very technical) Keybase for Everyone. And Keybase writing to the blockchain.
