What is DAI?

Question

What is DAI?

Accepted Answer

## TLDR
DAI is a decentralized, crypto-collateralized stablecoin that maintains a soft peg to the U.S. dollar, governed by its community through the MakerDAO (now Sky Protocol) ecosystem.

1. **Decentralized Dollar Alternative** – It's a stablecoin not backed by traditional bank reserves but by a surplus of on-chain crypto assets locked in smart contracts.
2. **Overcollateralized Stability** – Its $1 peg is maintained through a system where users must lock more collateral (e.g., 150%+) than the DAI they mint, with automated liquidations to manage risk.
3. **Community-Governed Protocol** – Key parameters, like accepted collateral types and stability fees, are voted on by holders of the ecosystem's governance token (historically MKR, now SKY).

## Deep Dive
### 1. Purpose & Value Proposition
DAI was created to provide a stable, decentralized digital dollar that operates independently of the traditional banking system. Unlike centralized stablecoins like USDT or USDC, which are backed by corporate-held fiat reserves, DAI is generated entirely on-chain. Its primary value is offering **censorship-resistant stability**, meaning no single entity can freeze user assets at the protocol level. This makes it a foundational building block for decentralized finance (DeFi), used for lending, trading, and as a stable store of value.

### 2. Technology & Stability Mechanism
DAI is an ERC-20 token on Ethereum. Its stability is engineered through the **Maker Protocol**. Users generate DAI by depositing approved collateral (like ETH, WBTC, or USDC) into "Vaults" (smart contracts). To protect the system from market volatility, this is done with **overcollateralization**; you might deposit $150 worth of ETH to borrow $100 in DAI. If the collateral's value falls below a set threshold, the position is automatically liquidated. This mechanism, combined with tools like the **Dai Savings Rate (DSR)** and the **Peg Stability Module**, creates economic incentives that help keep DAI's market price near $1.

### 3. Governance & Ecosystem Evolution
DAI is managed by a **decentralized autonomous organization (DAO)**. Governance power resides with holders of the ecosystem's token, which transitioned from MKR to SKY as part of the "Endgame" upgrade to **Sky Protocol**. These token holders vote on critical decisions, including adding new collateral types, adjusting risk parameters, and setting fees. The ecosystem has evolved into a modular structure with specialized **SubDAOs** (called "Stars") and introduced **USDS** as a new stablecoin, while DAI remains the flagship decentralized option.

## Conclusion
Fundamentally, DAI is a pioneering experiment in creating a resilient, non-custodial digital currency governed by its users rather than a central authority. How will its balance between decentralization and the integration of real-world assets shape its role as a global settlement layer?
