What is Dai (DAI)?

Deep Dive

1. Purpose & Value Proposition

DAI was created to provide a stable, decentralized digital dollar. Unlike centralized stablecoins (e.g., USDT, USDC), which rely on a company holding fiat reserves, DAI is generated by users who lock up cryptocurrency as collateral in the Maker Protocol (CoinMarketCap). This design aims to offer price stability without centralized control, making it resistant to censorship and appealing for global finance.

2. Technology & Architecture

DAI is an ERC-20 token on Ethereum. Users mint new DAI by depositing approved assets like ETH or WBTC into "Vaults" at a collateral ratio typically over 150%. This overcollateralization acts as a buffer against crypto price swings. If the collateral value falls too low, the system automatically liquidates it to protect DAI's dollar peg. Governance, through tokens like MKR (and later SKY), manages key parameters like which assets are accepted.

3. Ecosystem Fundamentals

DAI is a cornerstone of decentralized finance (DeFi). Its primary use is as a stable medium of exchange and store of value within crypto ecosystems. It is deeply integrated into major lending protocols (Aave, Compound), decentralized exchanges (Uniswap, Curve), and yield strategies. Users can also earn passive income through the DAI Savings Rate (DSR), which distributes a portion of protocol revenue.

Conclusion

Fundamentally, DAI is a community-governed, collateral-backed stablecoin engineered to bring dollar stability to the decentralized web. How will its evolving governance and collateral mix shape its role as the foundational money layer for DeFi?
