Blockchain is also backing a new mode of mapping. Crypto-cartographers hope to use it for spatial verification—confirming that things are where they say they are, when they claim to be there. How might this be useful? Well, you could know precisely when an Amazon delivery drone drops a package on your doorstep, at which point the charge would post to your account. No more unscrupulous delivery drivers, and no more contested charges for packages lost in transit. Or when opening a new bank account, you could virtually confirm your permanent address by physically being there during a particular verification period, rather than providing copies of your utility bills. You could also submit a photo of your flooded basement or smashed windshield to your insurance company, supplementing your claim with time- and location-verified documentation. Or, as you pass by your local family-owned coffee shop, the owner could “airdrop” some Bitcoin coupons to your phone, and you could stop by to cash in before the offer expires a half hour later.
