Building on the concept of providing proof-of-attendance tokens to developers and attendees of conferences/hackathons, the team behind Etheroom wanted to create chat rooms that can be accessed only by accounts that contain specific tokens. From there, they realized that they could give users the ability to mint their own tokens, thus allowing them to create more granular chat rooms, adding greater flexibility to their platform. They utilized dfuse to stream all event logs from the token contract so as to build a whitelist of accounts that can access specific chat rooms. From there, they were able to listen for any deltas, in order to revoke access should a user send that token to another address.
