what's stacks?
Stacks is a Bitcoin Layer 2 blockchain that enables smart contracts, decentralized applications, and DeFi protocols secured by Bitcoin's proof-of-work. It allows users to stack STX tokens to earn Bitcoin rewards, making Bitcoin holdings productive through native yield mechanisms. Key features include sBTC for deploying Bitcoin in apps without losing custody, 100% Bitcoin finality, and an ecosystem focused on activating the Bitcoin economy. The project supports Bitcoin-first innovations like BTC-backed DeFi and AI applications.
