What is Dai (DAI)?

Deep Dive

1. Purpose & Value Proposition

DAI was created to provide a stable, decentralized form of digital money. Unlike centralized stablecoins (e.g., USDT, USDC) that rely on a company holding fiat reserves, DAI’s stability is achieved algorithmically through over-collateralization on the Ethereum blockchain. This design aims to offer a transparent, globally accessible dollar-pegged asset free from single-point control or seizure.

2. Technology & Mechanism

Users generate new DAI by depositing approved cryptocurrencies like ETH or WBTC into Maker Vaults, which are smart contracts. To buffer against price swings, they must deposit more value than they borrow—a typical minimum collateral ratio is 150%. If the collateral's value falls too close to the loan value, the system automatically liquidates it to protect the protocol's solvency and DAI's peg.

3. Governance & Ecosystem Role

The rules of the Maker Protocol, including which assets are accepted as collateral and their associated risks, are governed by MKR (now SKY) token holders through a decentralized autonomous organization (DAO). This makes DAI a public utility. Its primary utility is within DeFi, where it is a preferred stable asset for lending on platforms like Aave, providing liquidity on exchanges like Uniswap, and earning passive yield through savings rates.

Conclusion

Fundamentally, DAI is a community-operated financial primitive that combines algorithmic stability with decentralized governance to create a resilient digital dollar. How will its role evolve as the protocol integrates more real-world assets and expands across blockchain networks?
