What is DAI?

Question

What is DAI?

Accepted Answer

## TLDR
DAI is a decentralized stablecoin on Ethereum that maintains a 1:1 value with the US dollar, governed by the MakerDAO community and backed by overcollateralized crypto assets.

1. **Decentralized Dollar Alternative** – It's a stablecoin not issued by a central entity but created and managed by a decentralized autonomous organization (DAO).
2. **Overcollateralized Backing** – Every DAI in circulation is generated when users lock other cryptocurrencies (like ETH or USDC) into smart-contract vaults at values exceeding the DAI minted.
3. **Community-Governed Stability** – Key parameters, like which assets can be used as collateral, are voted on by holders of the MKR (now SKY) governance token.

## Deep Dive
### 1. Purpose & Value Proposition
DAI was created to provide a stable, decentralized digital dollar. Unlike centralized stablecoins (e.g., USDC) that rely on company-held bank reserves, DAI's stability is enforced by transparent, on-chain smart contracts. This makes it a censorship-resistant form of dollar-denominated value, crucial for decentralized finance (DeFi) applications like lending, trading, and savings without traditional intermediaries.

### 2. Technology & Architecture
DAI is an ERC-20 token on Ethereum. Users generate new DAI by depositing approved collateral into Maker Vaults. The system requires **overcollateralization**—for example, locking $150 worth of ETH to mint $100 DAI—creating a safety buffer against price drops. If the collateral's value falls too close to the debt, the vault is automatically liquidated to protect the system and keep DAI's peg at $1.

### 3. Tokenomics & Governance
DAI has no fixed supply; its circulation expands or contracts based on user demand to mint or repay loans. The entire ecosystem, including the types of collateral and risk parameters, is governed by MakerDAO, a DAO where holders of the MKR (and now SKY) token vote on proposals. This decentralized governance is a core innovation, ensuring no single party controls the stablecoin.

## Conclusion
DAI fundamentally is a programmable, trust-minimized dollar built on blockchain, secured by excess crypto collateral and steered by its user community. How might its decentralized governance model continue to evolve to meet the demands of global finance?
