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 currency, DAI maintains its $1.00 peg through a system of over-collateralized crypto loans. This design aims to offer censorship resistance and transparency, as no single entity can freeze user assets. Its primary value is providing predictable value for transactions and savings within the volatile crypto ecosystem.

2. Technology & Architecture

DAI is an ERC-20 token on the Ethereum blockchain. Users generate new DAI by locking approved cryptocurrencies like ETH or WBTC into smart contracts called Vaults. To ensure stability, the value of the locked collateral must exceed the borrowed DAI value, typically by 150% or more. If the collateral's value falls below this safety threshold, the system automatically liquidates it to protect the DAI peg. This entire process is secured by Ethereum's underlying proof-of-work consensus.

3. Tokenomics & Governance

DAI has no fixed supply; its circulation expands and contracts based on user demand to mint or repay loans. The system is governed by MakerDAO, where holders of the MKR (and now SKY) token vote on critical parameters like which assets can be used as collateral, stability fees (interest rates), and system upgrades (CoinMarketCap). This democratic structure ensures the protocol evolves according to its community's decisions.

Conclusion

DAI is fundamentally a community-governed, algorithmically stabilized digital dollar that powers decentralized finance. How will its evolution within the new Sky ecosystem shape the future of decentralized money?
