So the concept is simple, imagine I want to give money to someone that has no wallets nor bitcoin can I send them bitcoins that are reserved for whoever can come with a PIN code and an address. From that point, they will get the bitcoins needed.

The concept is similar to a Check, you technically don't have the money, nor even the bank account. But having that piece of paper, you can go to the bank where the cheque was issue, and recieve your money.

Since bitcoin addresses are NOT like bank accounts in the sense that the only proof of ownerhsip is the private key. The user would be able to just generate a key download the keys and start with a file-based wallet (or even paper wallet).


If this concept has been thrown around or  a service already does this, would be interested in finding more about it.

Regards.
