What is Dai (DAI)?

Deep Dive

1. Purpose & Value Proposition

DAI was created to provide a stable, decentralized form of digital cash. It solves the problem of price volatility common in cryptocurrencies, enabling reliable payments, savings, and lending within the decentralized finance (DeFi) ecosystem. Its core value is censorship resistance; no central authority can freeze or seize DAI holdings, distinguishing it from centralized stablecoins like USDC or USDT (CoinMarketCap).

2. Technology & Stability Mechanism

DAI is an ERC-20 token on Ethereum. Stability is achieved through over-collateralization. To mint DAI, a user must deposit approved crypto assets into a Maker Vault at a value higher than the DAI they wish to create—typically over 150%. This buffer protects the system if the collateral's value falls. If a vault becomes undercollateralized, it is automatically liquidated to keep the entire system solvent and maintain the dollar peg.

3. Governance & Evolution

DAI is governed by MakerDAO (now rebranded as the Sky Protocol), a DAO where decisions are made by holders of its governance token. This community votes on critical parameters, such as which assets can be used as collateral and stability fees. The protocol has evolved from single-collateral DAI to its current multi-collateral form and now coexists with a new stablecoin, USDS, as part of the broader Sky ecosystem transition.

Conclusion

Fundamentally, DAI is a community-governed, algorithmic stablecoin that uses transparent, on-chain collateral to offer a decentralized dollar alternative. How will its role evolve as the broader Sky ecosystem continues to develop?
