"Identity is the most important factor in any conversation or transaction. ," says Doug Belshaw. Not that it needs to be ties to real-world identity, but you need to be able to establish some sort of credential. Keybase, described by Belshaw, is one such option. "Cross-platform apps for desktop and mobile devices have been added, mearning not only can you verify your identity across the web, but you can chat and share files securely, " he writes." My Keybase ID is https://keybase.io/downes - you'll notice it lists only Twitter and GitHub as confirmed identities (as opposed to the five listed by Belshaw). I used to also list my website, but my security certificate expired and I don't want to spend money on a new one.
