Stacks

About Stacks

Stacks is a blockchain that brings smart contracts and decentralized applications to Bitcoin. By leveraging Bitcoin's security, Stacks enables apps that are controlled by code rather than companies and are accessible to anyone. It operates as a layer-2 solution and sidechain to Bitcoin, allowing developers to build on top of the Bitcoin network.

• Stacks was originally known as Blockstack before rebranding.
• It uses a unique consensus mechanism called Proof of Transfer (PoX) that connects to Bitcoin's proof-of-work.
• Stacks smart contracts are written in Clarity, a decidable language designed for security and predictability.
• The STX token is used for transaction fees, executing smart contracts, and participating in consensus via stacking.
• Stacks is part of the Bitcoin sidechains ecosystem and is listed in multiple crypto indices.
