What exactly does (did) Keybase do? It was my understanding that Keybase worked like this: - Alice has a bunch of online accounts (Github, Twitter, LinkedIn, etc) - Alice wants someone who knows one of her accounts to be able to find all of her accounts - Alice generates a keypair (public P, private K) - Alice posts a certain kind of message signed by K somewhere on her public Github, public Twitter, and public LinkedIn - Alice uploads the account ID's to a server owned by Keybase - Keybase verifies the signed messages and keeps track of who has what accounts on what platforms - Bob asks the Keybase server who Alice (Twitter ID) is on other platforms - Keybase server returns a list of accounts - Bob can verify the returned list of accounts by running the signature verification himself (i.e. the Keybase server is only used for finding the account names) Basically in my mind, "Keybase == Somebody duct-taped together a PKI using public posts on social platforms." But reading others' comments I see that: - Keybase is a chat - Keybase is a better Git than Git - Keybase shares files securely - Keybase is a crypto wallet - Keybase is the KBFS filesystem - Keybase is easy for non-technical users to use Did I miss something?
