Bitlayer's Bitcoin smart contract system is now backed by mining pools controlling 31.5% of Bitcoin's network hashrate, marking a significant milestone for decentralized finance (DeFi) integration with the world's largest cryptocurrency.
Key Developments in BitVM Adoption
The BitVM implementation by Bitlayer has secured support from major BTC mining pools including:
- Antpool (17.2% hashrate)
- F2Pool (8.2% hashrate)
- SpiderPool (6.1% hashrate)
Andy Chow, CEO of Antpool, emphasized their commitment:
"As a bridge operator for Bitlayer, we're supporting Bitcoin innovation while safeguarding miner interests. The expansion of Bitcoin use cases will drive network activity, creating additional fee revenue for miners."
How BitVM Works
BitVM (Bitcoin Virtual Machine) enables complex smart contracts without protocol changes through:
- Off-chain computation with on-chain verification
- Taproot-based transactions encoding verification logic
- Optimistic rollup-like architecture for scalability

Mining Pool Impact
Mining pools play a critical role by:
- Validating non-standard transactions
- Including computational scripts in blocks
- Maintaining network security during transition
With 31.5% hashrate support:
- Every 3rd block can process BitVM transactions
- Developers gain testing environment
- Early-stage applications become feasible
Future Outlook
Bitlayer's contingency plans include:
- Expanding pool partnerships
- Adaptive protocol adjustments
- Gradual feature rollout
Industry observers note this could catalyze Bitcoin's DeFi ecosystem while preserving network stability.
FAQ: Bitcoin Smart Contract Revolution
Q: How does BitVM differ from Ethereum smart contracts?
A: BitVM maintains Bitcoin's security model while enabling limited smart contract functionality through off-chain computation.
Q: What risks exist with partial mining pool adoption?
A: Transaction processing delays may occur, but 31.5% support provides sufficient reliability for initial phases.
Q: How will this affect Bitcoin transaction fees?
A: Increased network activity from DeFi applications could create sustainable fee markets as block rewards diminish.
