The Canadian Bitcoin Index is a blended bitcoin index derived from a volume-weighted moving average from all trades conducted by Canadian exchanges.
CBIX uses Fanout to power the realtime endpoints of the CBIX API. The backend is a Laravel application.
The issue that I had was that there was no way of combining the convenience of a hosted solution such as Pusher with the flexibility of a public API provided by a self-hosted solution. This is where Fanout fits in.
