Reading Time: 3m
Stacks is a Smart Contract Layer built on Bitcoin, delivering decentralized applications and Smart Contract functionality to BTC by means of combining an independent execution layer and the Bitcoin settlement layer. The network anchors transaction status to the Bitcoin main chain through the Proof of Transfer (PoX) consensus mechanism and enhances transaction processing efficiency with Anchor Block and Microblock. Stacks aims to bring programmability and on-chain application capabilities to the Bitcoin ecosystem without altering the Bitcoin protocol.
