Fiat currency is a government-issued money declared as legal tender, deriving its value from the issuing government's creditworthiness rather than being backed by physical commodities like gold. As the predominant form of money in the modern global financial system, fiat currencies are managed by central banks or monetary authorities and carry the force of law for circulation and debt settlement.

IOU
An IOU (I Owe You) is a digital debt instrument on blockchain that represents a tokenized promise to repay a debt. These blockchain-based debt certificates enable creditor-debtor relationships to function without traditional financial intermediaries, operating through smart contracts in the DeFi (Decentralized Finance) ecosystem. IOUs provide alternative liquidity mechanisms for cryptocurrency holders through automated execution and settlement of debt obligations.
