idea is flawed. open to replay attacks.
idea is not yet mature. it is open only to improvement
this flaw is fatal and cannot be eliminated.
LOL. Zero points awarded until you can substantiate.
There's already a huge messaging overhead on the system, but the Crypt protocol would add significantly more messaging. This will be a disadvantage for scalability, but the real problem is replay attacks.
An adversary can easily DDOS the system by replaying the encrypted messages (they don't need to know the contents), just save them and resend them needlessly. Every peer must decrypt each message it encounters (pubkey/privkey crypto is expensive!). Note: the adversary doesn't need to perform any crypto, he can just replay messages over and over again for free. Everyone else has to do all the hard work. Bye bye network.
Idea sounds like it was written by a nigerian scammer.
