Blockchain profile
Stacks STX
Stacks is a Bitcoin-linked blockchain layer that adds smart contracts and decentralized applications while regularly anchoring to the Bitcoin network. Crypto traders and users track it for STX, applications, blocks, fees, transactions and data visible through explorers.

Key characteristics
- Native asset: STX, used for fees, some protocol economic interactions and applications in the Stacks ecosystem.
- Clarity smart contracts: Stacks uses a deterministic language designed to make contract behavior easier to inspect before execution.
- Bitcoin connection: Stacks blocks rely on a proof-of-transfer mechanism and publish anchors to Bitcoin according to protocol rules.
Use cases and ecosystem
- Bitcoin applications: DeFi, NFTs, identities, wallets and services that aim to extend use cases around BTC without changing Bitcoin itself.
- Market tracking: monitoring STX price, blocks, fees, transactions, contracts, volumes and network activity through explorers and crypto dashboards.
- Development: Clarity documentation, nodes, APIs, SDKs and open-source repositories related to the Stacks protocol.
Consensus and security
Stacks uses proof of transfer and anchors to Bitcoin, but security also depends on Stacks miners/validators, protocol rules, software upgrades, deployed contracts and wallet practices.
Fees and performance
Stacks fees vary with network demand, transaction or contract complexity and wallet parameters. Real-world costs and timing should be checked at time of use.
