The paid relays already take your key to whitelist entry, adding to the nostr.json at the same time wonβt be difficult.
Think it was Andre on Twitter who gave his ID as the email format recently - this becomes your nostr identity with NIP05 and your payment identity with Lightning, and should be a single identifier generally.
Take a look at my nostr.json. I signed it with my lightning key. I think something like this is the future of NIP-05.
Yes, maybe could list multiple pubkeys, wallets and relays with a single identity, this would allow you to use a single identity with a pubkey/wallet on each device and no need to transfer keys from device to device whilst also having some resilience to losing any one device. The nick/identity should be sovereign.
Then if relays publish NIP-05 information on relay.domain/.well-known/nostr.json it makes identification native to nostr infrastructure and recorded in multiple locations as a consensus reference and not reliant on a single point of failure.
What is stopping a scammer from stealing your identity and linking it to their npub?
In my case Iβve signed it with my lightning node. The problem with online identity is that you need to peg it to something. Easy for me since I have a well known lightning node now. Others tweet their npub, but that requires an established twitter following. Itβs a really hard problem.
Anyone can claim to be Elvis Presley.
The only way to avoid that is to set up NIP-05 as I have done. Using your real name and a real name DNS domain, with an SSL Certificate from a Certification Authority. This way you can port your real world ID to DNS and from DNS to a pubkey via NIP-05.
Lots of people here donβt like that though, and prefer the anonymity of a nym, thatβs OK. But I think they run a much higher risk of impersonation because nyms are easier to steal, as they are created out of thin air.
It all depends on where you want to trace your sovereignty from, either from yourself or from a nym you created. There are pros and cons for each approach.
Elvis has left the building
Arenβt there free ssls that donβt need your identity though
