Terms used in the xBacked protocol

Minting: the process of putting new xUSD tokens into circulation

Collateral: token types allowed to be deposited when opening a vault. To begin with, xBacked will only support ALGO.

System Debt: the total supply of xUSD in the system

Vault: owned by a user, and it is the primary mechanism for a user to mint xUSD

Vault Debt: the amount of xUSD a vault minted.

Liquidation: performed by the xBacked protocol using xUSD staked in the liquidation pool. Will liquidate vaults with an unhealthy collateral ratio.

Redemption: allows users to redeem 1 xUSD for $1 of system collateral. This is done by selecting the riskiest vault in the system.

Withdrawing: the process of removing collateral in a vault, back into your wallet.

Collateral Ratio: the ratio of collateral to debt. The system, and vaults within the system, must always have more collateral than debt to maintain the peg.
