in september 2017, keybase launched keybase teams. a team is described as "...a "named" group of people." each team has a private folder in the keybase filesystem, and a number of chat channels (similar to slack). teams can also be divided into "subteams" by placing a codice_9 in the team name. for example, codice_10 would be a subteam of codice_11, while codice_12 would be a subteam of codice_10 (and therefore, also of codice_11).
