It is crucial to understand what is **Whisper Notification Service** is designed for:
- to augment Whisper/5 functionality, by allowing clients to subscribe to arbitrary node that has service enabled
- once subscribed, client receives randomly generated symmetric key, which is used to control subscription (say, manage blacklists). Among other things, the key can be used to trigger notification, by-passing any black/white lists
- everywhere possible, Whisper protocol itself was used. For example, discovery mechanism is nothing more but Whisper message exchanges between parties. The same goes for notification sending.
- the aim was to keep the Notification Server part as slim as possible
