DAI (Dai Stablecoin) is Ethereum's largest decentralized stablecoin, developed and managed by MakerDAO. As a foundational element of decentralized finance (DeFi), DAI maintains a 1:1 peg with the US dollar (1 DAI = $1 USD) through over-collateralized crypto-backed loans. Individuals and businesses can use DAI for避险资产 (hedging) or liquidity access via抵押借贷 (collateralized borrowing).

- Algorithmically stabilized via Maker Protocol's smart contracts
- Transparently collateralized by crypto assets like ETH and WBTC
Blockfer analysts project continued growth for DAI as MakerDAO expands its liquidity options and financial use cases.

FAQ: Addressing Common DAI Questions
Q: Is DAI really decentralized?
A: Yes. While early versions used centralized collateral, current DAI is backed by decentralized assets with governance by MKR holders.
Q: What happens if DAI loses its peg?
A: The system automatically adjusts stability fees and liquidation ratios to restore balance. Historical deviation never exceeded ±3%.
Q: Can I use DAI for payments?
A: Absolutely. Many crypto payment processors (like BitPay) support DAI for merchant transactions.
Q: How is DAI different from TerraUSD (UST)?
A: Unlike algorithmic UST, DAI maintains over-collateralization, preventing death spiral scenarios.
Investment Perspective: Is DAI Worth Holding?
While not an appreciating asset, DAI offers:
- Portfolio Stability: 24/7 dollar exposure
- Earning Potential: DSR yields outperform传统储蓄 accounts
- DeFi Utility: Required for many advanced strategies
Note: Always conduct your own research before investing.
