imho the more interesting cryptopgraphic proof would be proof of address or bounding box. I feel that if you allowed third-parties to pay you for supporting a validation of locality via cryptographic features sent in postcard, then the rails would come off what was possible with digital systems. Knowing location will be increasingly powerful imho. Our opinions count most in a local spaces, at least with city-building. And I feel that third parties would be willing to fund the main cost of postage, if it allowed them to be assured of certain geographic bounds of users.
In order to cheat that system, people would need to engage in mail fraud or buy a PO box.
Happy to discuss, chris. Sidewalk Labs is setting up camp in Toronto, and I was speaking about the above at a local event, and they were really interested in the concept. I had a call with their head of identity, but was disappointed that he couldn't say anything of substance on _why_ it was relevant to SL efforts, at least not without my signing an NDA. As a community organizer in the civic tech scene, I had no interest in that. More secrecy in the smart city / open gov sector :/ blech
