What is Dai (DAI)?

Deep Dive

1. Purpose & Value Proposition

DAI was created to provide a stable, decentralized digital dollar. Unlike stablecoins backed by bank-held fiat reserves, DAI’s stability is achieved algorithmically on-chain. This design aims to offer a censorship-resistant and transparent store of value and medium of exchange for the decentralized finance (DeFi) ecosystem, operating without a central issuer that can freeze funds.

2. Technology & Collateral Mechanism

DAI is an ERC-20 token on Ethereum. Its core stability mechanism is over-collateralization. Users lock assets like ETH or WBTC into Maker Vaults (smart contracts) to generate DAI as a loan. They must maintain a collateral ratio typically over 150%, creating a buffer against price swings. If the collateral value falls too low, the system automatically liquidates it to protect DAI’s peg. This structure ensures each DAI in circulation is backed by more value than it represents.

3. Governance & Evolution

DAI is not controlled by a single entity. Its protocol is governed by MakerDAO (undergoing a rebrand to Sky Protocol), a decentralized autonomous organization (DAO). Holders of the governance token (MKR, transitioning to SKY) propose and vote on critical parameters like collateral types, stability fees, and system upgrades. This community-led model underpins DAI’s decentralized nature and adaptive evolution, including its coexistence with the newer USDS stablecoin within the Sky ecosystem.

Conclusion

Fundamentally, DAI is a community-governed, over-collateralized digital dollar that provides a decentralized alternative to traditional stablecoins. As the protocol evolves, how will its core principles of decentralization and stability balance with broader institutional adoption?
