"Introducing Proof of Place, an out–of-band process where an oracle, such as  @BTCMap.org, would mail - yes mail a physical letter - a shared secret to the physical location being claimed in cyberspace. This shared secret would be locked to the public key (npub) making the claim, which, if unlocked, would prove that the associated private key (nsec) has physical access to the location in meatspace.

One way of doing this would be to mint a 1 sat cashu ecash token locked to the npub of the claimant and mail it to them. If they are able to redeem the token then they have cryptographically proven that they have physical access to the location."

 Seems “blockchainey” to add a token to something that doesn’t need it.

If there is benefit to the payment, like @keychat is doing, then it makes sense.

Otherwise, just do a Nostr key verification scheme. 

 I like how it sounds but what would be a use case? 

 Did you read the article? 

 My bad... completely missed the links at the bottom... 😆
