What is Stacks?

Stacks is the leading Bitcoin L2. Stacks allows developers to leverage Bitcoin as a secure base layer for apps and smart contracts. The Stacks layer accelerates Bitcoin's scalability and programmability with fast blocks times, Bitcoin-finality, and seamless decentralized BTC deposits and withdrawals.
Stacks activates the Bitcoin economy. Bitcoin is the most adopted, most valuable, and most decentralized cryptocurrency. The Stacks L2 enables fast, cheap BTC and full-featured smart contracts on the L2 without modifying Bitcoin itself. Users and developers can use BTC in their apps and pay gas fees with BTC. All transactions on Stacks L2 are secured by Bitcoin L1 with 100% Bitcoin finality.

What makes Stacks unique?

As a Bitcoin layer for smart contracts, Stacks has the following innovations that make it unique:
  • Proof-of-Transfer consensus means all transactions on Stacks are settled to Bitcoin, allowing applications to leverage Bitcoin’s security without modifying the Bitcoin L1
  • Stacks uses the Clarity programming language for safe, decidable contracts. Stacks has knowledge of the full Bitcoin state, thanks to Proof of Transfer and Clarity, enabling it to read from Bitcoin at any time. 
  • All transactions on Stacks, settle to Bitcoin, offering strong security guarantees. Further, after the upcoming releases in 2024, Stacks will be secured by the entire hash power of Bitcoin, see upgraded transaction speed, and the addition of sBTC to the network.
  • sBTC is 1:1 Bitcon-backed asset on the Stacks layer that enables smooth movement of BTC from the L1 to the L2 and back while remaining decentralization. https://sbtc.tech
