How Does the Collateralization Mechanism of Stablecoins like DAI Differ from Centralized Ones like USDC?
USDC is fiat-backed, meaning each token is redeemable for one US dollar held in a traditional bank account, making it a centralized IOU. DAI is crypto-collateralized, backed by a basket of other cryptocurrencies locked in smart contracts, making it decentralized and over-collateralized.
The stability of DAI relies on market incentives, liquidation mechanisms, and governance adjustments, rather than a direct bank deposit.
