What is Stacks (STX)?
Stacks (formerly Blockstack) is an open-source blockchain platform that brings smart contracts and decentralized applications (DApps) to Bitcoin. As a layer-2 solution, Stacks enhances Bitcoin's functionality without modifying its core protocol, preserving Bitcoin's renowned security while adding programmability.
Key Features:
- Smart Contracts on Bitcoin: Uses Clarity language for secure, predictable execution
- Proof of Transfer (PoX): Energy-efficient consensus mechanism leveraging Bitcoin's security
- Native Token (STX): Powers DApps, DeFi protocols, and network governance
How Stacks Works
Technical Architecture
Stacks operates through three key components:
- Clarity Smart Contracts
Designed for transparency and security, reducing vulnerabilities common in other languages. Proof of Transfer (PoX)
Miners use Bitcoin to validate Stacks blocks, receiving STX rewards:- 80% to miners
- 15% to STX holders (via stacking)
- 5% for developer rewards
- Microblocks
Process transactions between Bitcoin blocks for faster throughput (~5s settlement).
Interoperability with Bitcoin
Every Stacks block is anchored to a Bitcoin block, creating an immutable record backed by Bitcoin's hash power.
STX Tokenomics
| Metric | Value |
|---|---|
| Total Supply | 1.818 billion STX |
| Circulating Supply | 1.38 billion STX |
| Inflation Schedule | Fixed annual emission (like Bitcoin) |
| Hard Cap ETA | 2050 |
Distribution (Genesis Block):
- 29.93% - 2018 Token Sale
- 22.20% - Short-term Treasury
- 13.53% - Founders
- 9.09% - 2019 Token Sale
Use Cases of STX
- Network Participation: Stacking rewards, transaction fees
- DApp Development: Building on Stacks ecosystem
- Governance: Voting on protocol upgrades
- DeFi/NFTs: Access to Bitcoin-based financial applications
The Nakamoto Upgrade
Scheduled for 2024, this major upgrade introduces:
- Bitcoin-backed security: Inherits Bitcoin's hash power
- Atomic BTC Swaps: Trustless Bitcoin/STX exchanges
- Faster Transactions: Sub-10 second finality
- Improved Peg Mechanism: Enhanced BTC interoperability
STX Mining vs. Stacking
| Aspect | Mining (PoX) | Stacking |
|---|---|---|
| Requirement | Hold BTC | Hold STX |
| Reward | New STX tokens | BTC from fees |
| Energy Use | Low | None |
FAQ

Future Outlook
With increasing adoption of Bitcoin DeFi and the Nakamoto upgrade, Stacks is positioned to become a cornerstone of Bitcoin's smart contract ecosystem. Its unique integration model offers developers a secure way to build on Bitcoin's unmatched network effects.
**Optimizations**:
1. Added structured tables for data presentation
2. Included anchor texts at strategic points
3. Expanded technical details about PoX and Clarity
4. Organized content with clear hierarchical headings
5. Removed all external links except OKX
6. Added comparative table for mining/stacking
