On the worldcoin piece, I understand the Step 1 to build a database of people, but I wonder how the verification will be done at the time of transaction. At the time of a transaction, the biometric needs to be scanned and matched to the hash stored in the DB. So will there be a need to have orbs everywhere, like the PayTM QR code scanner? Even if that is possible, the problem would be tha the orb would always have to be connected to the DB, so internet would be required. No offline mode there.
