I am interested in Whisper. I read that Whisper is based on Ethereum p2p protocol on github. Then does ethereum mainnet support Whisper on itself too ?
Anyway, what I wonder is ...
1. Is Whisper only supported on private networks ?
2. If the purpose of someone's private network is for exchanging Whisper messages only, then what is the data in the private blockchain ?
There is no white paper for Whisper now.. Does anyone have an idea ?
