LUNA is the native cryptocurrency of the Terra blockchain, designed to support a system of algorithmic stablecoins and maintain price stability within the ecosystem. It plays a central role in balancing supply and demand, as well as securing and governing the network.

LUNA primarily functions through a mint-and-burn mechanism. When demand for Terra’s stablecoins, such as TerraUSD (UST), increases, LUNA is burned (destroyed) to mint new stablecoins. This reduces LUNA’s supply, potentially increasing its value. Conversely, when demand for stablecoins falls, UST is burned, and new LUNA is minted, increasing its supply. This dynamic process helps maintain the stablecoin’s peg to its target value.

Another key function of LUNA is staking. Users can stake LUNA with validators to help secure the network and validate transactions. In return, they earn rewards from transaction fees and network incentives. This staking model is based on a delegated proof-of-stake system, ensuring both efficiency and decentralisation.

LUNA also plays a role in governance. Token holders can vote on proposals, such as protocol upgrades or changes in network parameters, giving the community influence over the blockchain’s future.

Overall, LUNA acts as the backbone of the Terra ecosystem by enabling stability, security, and decentralised decision-making.
