## What STX-USD Is

Stacks is a Bitcoin-focused smart-contract network that operates as a separate execution layer anchored to Bitcoin, adding programmable functionality without changing Bitcoin's base protocol [[15]](https://coinstats.app/ai/a/fundamental-analysis-blockstack). STX is its native token, used for transaction fees, smart-contract activity, network participation, and Stacking [[15]](https://coinstats.app/ai/a/fundamental-analysis-blockstack). The network uses Proof of Transfer (PoX) consensus, in which miners commit BTC to compete for block production, and STX holders lock tokens through Stacking to receive BTC-denominated rewards [[15]](https://coinstats.app/ai/a/fundamental-analysis-blockstack). The ecosystem also includes sBTC (a decentralized Bitcoin-backed asset), ALEX/Bitflow (DEX liquidity), Zest Protocol (lending), and wallets like Leather and Xverse [[15]](https://coinstats.app/ai/a/fundamental-analysis-blockstack).
