Pegged/Anchored or FLoating
Examples of Pegged Stablecoin: USDC, UDST (anchored to US Dollars)
Floating stablecoin has its buying power that stays relatively the same over time, but is not tied down to any other asset
Mechanism that keeps the coin stable, it revolves around minting and burning the stablecoins.
Centralized body that controls the minting and burning of the coins (governments, organizations...)
Governed by a permissionless algorithm with no human intervention, a set of autonomous code dictates the minting/burning.
How the stablecoin is backed (what is giving it value)
USDT --> US Dollars
DAI --> Backed by ETH...
If the stablecoin fails, the underlying collateral also fails.
Endogenous collateral originates from inside the protocol
Example: UST (Luna)
If the stablecoin fails, the underlying collateral survives.
Exogenous collateral originates from inside the protocol
Example: USDC, DAI
