### Mobile nodes
This is a Whisper node which connects to part of the Whisper network. It MAY
relay messages, and it MUST set a PoW requirement of at least `0.01` to be
accepted by other Status nodes.
relay messages. See next section for more details on how to use Whisper to
communicate with other Status nodes.
## Whisper adapter
Once a Whisper node is up and running there are some specific settings required
to commmunicate with other Status nodes.
### Node configuration
Whisper's Proof Of Work algorithm is used to deter denial of service and various
spam/flood attacks against the Whisper network. The sender of a message must
perform some work which in this case means processing time. Because Status' main
client is a mobile client, this easily leads to battery draining and poor
erformance of the app itself. Hence, all clients MUST use the following Whisper
node settings:
* proof-of-work not larger than `0.002`
* time-to-live not lower than `10` (in seconds)
