What is Dai (DAI)?

Deep Dive

1. Purpose & Value Proposition

DAI was created to provide a stable, decentralized form of digital cash. Unlike centralized stablecoins (e.g., USDT, USDC) that hold fiat reserves in banks, DAI's stability is engineered entirely on-chain. This makes it censorship-resistant and accessible globally, serving as a foundational dollar-denominated asset for decentralized finance (DeFi) applications like lending, trading, and payments.

2. Technology & Mechanism

DAI is generated through a process involving Maker Vaults. Users deposit approved collateral assets at a ratio typically exceeding 150% of the DAI they wish to mint. This over-collateralization acts as a safety buffer. If the collateral's value falls too close to the debt, the system automatically liquidates it via auctions to keep DAI fully backed, maintaining the dollar peg.

3. Governance & Ecosystem Evolution

DAI is governed by MakerDAO, where MKR token holders vote on critical decisions like which assets to accept as collateral and stability fee rates. The ecosystem is evolving; MakerDAO has rebranded to Sky Protocol and introduced USDS as an upgraded stablecoin. DAI remains active and convertible 1:1 with USDS, coexisting within this new modular framework (Lucky).

Conclusion

Fundamentally, DAI is a pioneering decentralized stablecoin that combines over-collateralized backing with transparent, community-led governance to offer a stable digital dollar. As the protocol evolves into the Sky ecosystem, how will its core principles of decentralization and stability adapt to increasing institutional integration?
