BitVM and @BitlayerLabs : Smart Contracts in the Bitcoin Fortress
Bitcoin has always been recognized as the safest store of value, but its lack of smart contracts limited its potential compared to Ethereum. This is where BitVM comes in, an architecture that expands Bitcoin's programmability without weakening its security.
What is BitVM?
Created by Robin Linus, BitVM allows transactions on Bitcoin to be structured as smart contracts. Its evolution brought two phases:
• BitVM1: introduced generic computation with interactive transaction verification.
• BitVM2: advanced to an open challenge model, more decentralized and secure.
In practice, it operates through HTLCs, pre-defined transaction graphs, and pre-signatures, ensuring immutability. Additionally, a multisig committee certifies execution, where only one honest member is needed to preserve the integrity of the contract.
The role of #Bitlayer
Based on this foundation, Bitlayer emerges as a layer 2 that brings Ethereum-style programmability to Bitcoin. It offers:
• Security inherited from Bitcoin
• EVM compatibility
• Scalable rollups
• Trustless BTC bridges
This paves the way for DeFi, dApps, and native exchanges in the Bitcoin ecosystem.
Real impact
Bitlayer has already attracted attention at events like Conviction 2025, where it revealed raising over $6 million and highlighted its vision to unite traditional finance with DeFi on Bitcoin.
Conclusion
BitVM and Bitlayer transform Bitcoin: from a simple store of value to a programmable and interoperable infrastructure — a revolutionary leap towards BTCFi.
