In practice, when we fill out an envelope, we don’t need to include the sender’s information; we only need to write the recipient’s address, and there’s no need to write the recipient’s name. As long as the recipient’s address is precise enough, the letter can be successfully delivered. Not needing to write the sender’s information is equivalent to being able to write any random address.

Can keychat use nostr npubs to initiate conversations or does this compromise security? The idea of public global ID system with eCash to prevent spam is great, but I don't see contacts in keychat.
I believe we are in massive need for this technology the doors are closing for privacy. it seems like the general publics are just sleep walking into surveillance and control. I phone still having record sales, copilot + PCs starting to get traction and these companies are massively incentivised to extract as much data from consumers to compete in the AI race for control of super intelligence.
