Stacks is a Bitcoin Layer 2 solution that enables smart contracts and decentralized applications to operate using Bitcoin as a secure base layer, without modifying the Bitcoin protocol itself. It employs the Clarity smart contract language, designed for safety and transparency, and utilizes a consensus mechanism called Proof of Transfer (PoX) to anchor its blocks to Bitcoin's blockchain, thereby inheriting Bitcoin's security. Additionally, Stacks introduces sBTC, a decentralized two-way Bitcoin peg, allowing BTC to be used in smart contracts and DeFi applications on the Stacks network.
Stacks empowers users to access smart contracts and DeFi while leveraging Bitcoin’s unmatched security and decentralization. It allows holders to earn BTC rewards through stacking, promoting active network participation. With sBTC, users can utilize their Bitcoin in decentralized applications without relinquishing custody or security.
