What is DAI? I saw a couple of questions about the stablecoin DAI:

$DAI (-0,04 %) is a stablecoin, a type of cryptocurrency that is designed to maintain a stable value compared to a fiat currency, such as the US dollar. DAI is created and maintained by a decentralized lending platform called MakerDAO.

MakerDAO's system is built on the Ethereum blockchain, and it uses a process called "collateralized debt position" (CDP) to generate DAI. In order to generate DAI, a user must deposit collateral, such as Ether (ETH), into a CDP, and then borrow DAI against that collateral. The value of the collateral must be greater than the value of the borrowed DAI, and the collateral can be liquidated if the value of the collateral drops below a certain level (known as the "liquidation ratio").

The value of DAI is kept stable by a dynamic system of incentives and penalties. When the value of DAI falls below the target value of $1, users can increase the supply of DAI by borrowing more and depositing more collateral, which helps to increase the price. When the value of DAI rises above the target value, users can reduce the supply of DAI by paying back their loans and withdrawing their collateral, which helps to decrease the price.

The system is also using an autonomous agent called the "MakerDAO" that uses an algorithm that adjusts the stability fee and debt ceiling, this allows to maintain the value of DAI as close as possible to $1.

DAI is unique among stablecoins in that it is fully decentralized and does not rely on any central authority or organization to maintain its value. This makes it more resistant to censorship and manipulation, but also means that it is subject to the same volatility and risk as other cryptocurrencies.
