Blog author here. In the interest of keeping the post more of a summary, we left the cryptographic details to our docs. Here's a link to that: https://keybase.io/docs/teams/index . We're happy to answer questions here.
This really is an exciting product for us. Once you can define a team, cryptographically, without server trust, a lot of other things follow. We'll be launching some of those things in the coming weeks.
Also left out from the blog post: teams (and chats) can be controlled through a local API, so pretty much everything in Keybase can run in the form of a bot, also without trusting Keybase servers. Cheers to crypto!
