What is money, and when is it digital?

Three ways to see it

1. 1

   Economists give money three jobs. First, medium of exchange: you accept it because you trust the next person will too. Second, store of value: it should not lose meaning between Friday salary and Monday rent. Third, unit of account: you can price a samosa, a flat in DHA, and a barrel of oil on the same scale. A thing is more or less money depending on how well it does all three. PKR notes excel at the first, struggle with the second during high inflation, and dominate the third inside Pakistan. Gold reverses this: bad medium, strong store, weak unit. Easypaisa balance is mostly medium plus unit; it is not a deep store of value, it is a movement layer.

2. 2

   Way one to understand digital money: trace what is actually being moved. When you tap Easypaisa to send PKR 5,000 to your cousin in Multan, no rupee notes travel. A database row at the wallet operator deducts 5,000 from your column and adds 5,000 to his. The underlying value is still PKR held at a scheduled bank in the operator's pooled account. The phone screen is a window onto a ledger. This is digital money in its plainest sense: ledger entries denominated in fiat, run by a regulated institution.

3. 3

   Way two: ask who keeps the ledger and who can reverse it. With a bank deposit, the ledger sits with the bank, the State Bank supervises, and reversals are governed by Pakistan's payment system rules plus chargeback conventions. With RAAST, the State Bank itself runs the rails between banks. With cash, there is no ledger; possession is the proof. With Bitcoin, the ledger sits on thousands of computers nobody controls, and reversal is effectively impossible after a few confirmations. The same word money hides four very different governance models.
