How is xDai different than Dai?

Dai is a stablecoin issued by the Maker organization that is also pegged 1:1 to the USD. However, unlike xDai, Dai is backed by Ethereum collateral. In order to create Dai tokens, an Ethereum holder would need to send their ether to a collateralized debt position (CDP) thus creating a smart contract and allowing users to share value on the Ethereum blockchain. For more info check out link to DAI whitepaper on Maker website.

Introducing xDai

xDai is a USD stable coin that is an exact representation of DAI but lives on xDai Chain instead of the Ethereum network. xDai's peg will always remain 1:1 with USD and will serve as the native token on xDai Chain. This means a stable coin will be used as the currency for transaction fees on this new network.

The only way to mint xDai tokens is by taking DAI tokens and using the xDai bridge to move them over from the Ethereum network to xDai Chain. The market cap for xDai Chain will update in real-time and directly reflect how many xDai tokens there are in existence.
