encrypt memo with recipient's public key
recipient proactively scans for encrypted message
no way to tell who is talking to who :)
Yes... to avoid metadata analysis. That's the point!
NSA can see me post encrypted memo but...
they don't know who I sent it to because...
recipient will proactively scan for any messages...
Private chat no need to record on chain
recipient's logic: if can decrypt, it must be for me
Peer to peer straight forward.Complicated beyond that
trying to revive this topic...
abstract is essentially this: the recipient proactively scans the blockchain for encrypted messages thereby defeating metadata analysis – ie can't see who's talking to who.
Why not just open a standard p2p encrypted communication channel between two people who follow each other? You just have a separate p2p app with a pub username linked to memo account
