#STX USDTWhat Is Stacks (STX)?
Stacks is a Bitcoin Layer for smart contracts; it enables smart contracts and decentralized applications to use Bitcoin as an asset and settle transactions on the Bitcoin blockchain.
Bitcoin is the largest, most valuable, and most durable decentralized asset. The Stacks layer unlocks $500B in BTC capital using the Bitcoin L1 as settlement for decentralized applications.
Stacks has knowledge of the full Bitcoin state, thanks to its Proof of Transfer consensus and Clarity language, enabling it to read from Bitcoin at any time.
All transactions on the Stacks layer are automatically hashed and settled on the Bitcoin L1. Stacks blocks are secured by 100% Bitcoin hashpower. In order to re-order Stacks blocks/transactions, an attacker would have to reorg Bitcoin.
