orange check = proof of work
communications need costs, w/o costs we get junk mail, bot requests, and much more fraud
I don't see what the Orange Check that nostr:npub15dqlghlewk84wz3pkqqvzl2w2w36f97g89ljds8x6c094nlu02vqjllm5m and nostr:npub1jt97tpsul3fp8hvf7zn0vzzysmu9umcrel4hpgflg4vnsytyxwuqt8la9y talk about really changes.
Why is signing your data not enough to proof it was really you? I see the case for a proof on the BTC timechain for timestamping some of your publications, but why is that needed for your npub itself too?
Discussion
I can filter incoming communications with my social graph and easily attach a cost/zap for users I don't know yet. No need for an npub on the bitcoin base layer there, no?
what happens when 100 Niel Liesmons follow me? which one is real?
adding a cost is the point, 0 friction = unlimited spam, fraud, theft, annoyance, etc.
if it cost real Bitcoin to send email, we'd have less spam (which is what proof of work was designed for)
The one that can sign with my private key.
Not, for example, the one that spent the most sats on his npub.
Agreed with the spam-filter. Attaching bitcoin or proof of work to unknown incoming communications as a "cryptographic wall of energy" (to quote Saylor) is something I need as well. But that is up to me to determine how expensive crossing that wall should be.
