Stacks makes it do more. Stacks is a layer on top of Bitcoin that adds smart contracts, apps, and real yield without changing Bitcoin itself. STX is its native token. The Opportunity Bitcoin has a $1T+ market cap and the strongest security in crypto. But on its own, it can't run apps, power DeFi, or generate yield. Stacks changes that. View the docs REad the whitepaper Why Stacks is built on Bitcoin Other chains start from scratch. Stacks starts from the most trusted, most capitalized, most battle tested network ever created. 1 $1T+ Market Cap The largest pool of capital in crypto is sitting idle. Bitcoin is accessible in most of the world and continues to see retail and institutional adoption. But its limited scripting language means almost none of that capital is programmable. Stacks changes that without changing Bitcoin. The $1T opportunity 2 100% Bitcoin Finality Transactions settle to the most secure chain in existence. Every Stacks block is anchored to Bitcoin. After the Nakamoto upgrade , reversing a confirmed Stacks transaction would require reorging Bitcoin itself. That's not theoretical security. It's inherited finality. Bitcoin Finality 3 99.99% Uptime Built on a foundation that was built to last. Bitcoin has been running since 2009 with near perfect uptime. No restarts, no rollbacks, no downtime. When you build on Bitcoin, you build on the most reliable base layer in the history of computing. Bitcoin Uptime What is Stacks The Leading Bitcoin L2 Nakamoto Upgrade sBTC Proof of Transfer Clarity Smart Contracts $1T+ in security behind every transaction. Stacks is the most widely adopted Bitcoin layer for smart contracts. Every Stacks block is cryptographically anchored to Bitcoin, inheriting the security of the most battle-tested blockchain in existence.Unlike sidechains or standalone L1s, Stacks doesn't just bridge to Bitcoin. It settles on Bitcoin. That means your transactions, contracts, and assets are backed by the full weight of Bitcoin's hashpower. View the docs LEARN MORE Fast blocks and Bitcoin-grade finality. The Nakamoto upgrade, activated in October 2024, was the biggest milestone in Stacks history. It brought block times down from ~10 minutes to ~5 seconds and introduced 100% Bitcoin finality. That means once a Stacks transaction is confirmed, reversing it would require reorging Bitcoin itself. You get the speed of a modern L2 with the irreversibility of Bitcoin. It's the best of both worlds. View the docs LEARN MORE Your Bitcoin, working for you. sBTC is a 1:1 Bitcoin-backed asset on Stacks. Deposit BTC and receive sBTC that you can use across DeFi, lending, and decentralized apps. When you're done, redeem it back for the exact same amount of BTC. sBTC is secured by a decentralized set of signers and is the key that unlocks Bitcoin for programmable finance. Launched December 2024, with over 5,000 BTC deposited. View the docs Learn About sBTC The consensus mechanism that connects Stacks to Bitcoin. Proof of Transfer (PoX) is how Stacks stays anchored to Bitcoin without modifying Bitcoin itself. Miners compete by spending real BTC to mine new Stacks blocks. That BTC goes directly to STX holders who participate in Stacking. It creates a virtuous cycle: miners commit Bitcoin, Stackers earn Bitcoin, and every block is recorded on the Bitcoin chain. Real yield from real economic activity. View the docs HOW PoX WORKS A smart contract language designed to be predictable. Clarity is the programming language that powers Stacks smart contracts. It's decidable, meaning you can know exactly what a contract will do before you execute it. No surprises, no hidden behavior, no reentrancy exploits. Clarity is also interpreted, not compiled, so the source code on-chain is exactly what runs. It can read Bitcoin state natively, letting contracts respond to BTC transactions directly.
