I am not sure if Whisper is the right thing or not, but we need some way for nodes in our network to communicate. I think, the most important properties are:
- To minimize the time from connecting to the network and communicating with any node over there;
- The speed of response;
- Python support.
Whisper v1 seemed a little bit heavy-weighted with sending messages to everyone. Perhaps, one way would’ve been do use devp2p or to wrap libp2p, but we went our own way, summarized here: https://blog.nucypher.com/why-were-rolling-our-own-intra-planetary-node-discovery-at-nucypher-beeb53018b0
