Bitlayer is the first Bitcoin Layer 2 built on the BitVM paradigm.
Overview
• It brings smart contract functionality, scalability, and DeFi capabilities to Bitcoin without altering its base protocol.
• Think of it as a secure, EVM-compatible sandbox where applications can run on Bitcoin’s unmatched
• Bitlayer turns that vision into reality by making Bitcoin programmable while keeping its original security intact.
• Developers can now use Ethereum-style tools to build, but on Bitcoin’s base trust—like plugging Ethereum’s creativity into Bitcoin’s stability.
• It’s not just an upgrade, it’s Bitcoin’s second life - secure, scalable, and open to innovation.
• Smart Contract Layer on Bitcoin – Supports EVM (Solidity) and other runtimes, including CairoVM.
• Hybrid Execution Model – Combines optimistic rollups with ZK-proof validation for scalable yet secure computation.
• Native BTC Bridge – Enables trust-minimized, two-way Bitcoin transfers via BitVM without custodians.
• EVM Compatibility – Developers can deploy Ethereum applications directly onto Bitlayer with minimal changes.
• DeFi Integration – Unlocks BTC liquidity for trading, lending, and derivatives on-chain.
• BitVM-based Design – Built on Bitcoin’s scripting capabilities, ensuring no fork or protocol change is required.
• Security Anchored to Bitcoin – State proofs are submitted directly to the Bitcoin main chain, backed by real mining power.
• Mining Power Participation – Pools like Antpool, F2Pool, and SpiderPool contribute to validating execution.
• Rollup Architecture – Functions like Ethereum rollups, batching transactions and submitting proofs to Bitcoin L1.
• Cross-Chain Expansion – Connecting Bitcoin assets to ecosystems like Arbitrum, Starknet, and Base.
Core Offerings
• EVM-Compatible Smart Contracts – Deploy Ethereum apps on Bitcoin securely.
• Optimistic + ZK Execution – Combines efficiency with cryptographic proofing.
• Trustless Bitcoin Bridge – Move BTC across chains without intermediaries.
• Developer Ecosystem – Provides familiar tools for Ethereum devs to build on Bitcoin.
Technical Edge
• Bitcoin Security Without a Fork – No need to change Bitcoin’s base layer.
• Modular Rollup Framework – Customizable data availability for cost and performance optimization.
• High Scalability – Supports higher throughput than Bitcoin L1 while preserving trust.
• Cross-Chain DeFi – Enables Bitcoin assets to flow into Ethereum-like DeFi ecosystems.
Innovations and Ecosystem Momentum
• Bitcoin-Native Rollup – Evolving beyond sidechains into a true rollup secured by Bitcoin.
• Velar Integration – Velar uses Bitlayer for its Bitcoin-native PerpDex (perpetual DEX).
• Expanding Ecosystem – Developers and DeFi protocols are adopting Bitlayer to tap into BTC’s $1.9T liquidity.
• Real Interoperability – Extending Bitcoin into Ethereum, Starknet, and Arbitrum ecosystems.
Why It Matters
• For developers - Familiar EVM tools but secured by Bitcoin’s immutability.
• For users - Access to DeFi, gaming, NFTs, and apps without leaving Bitcoin.
• For the ecosystem - Finally unlocks Bitcoin’s vast liquidity for Web3 use cases.
Conclusion
• Bitlayer is not just another Layer 2—it’s Bitcoin reimagined for Web3.
• By adding programmability, scalability, and interoperability, it brings Bitcoin’s $1.9T in capital into the world of smart contracts and decentralized applications.
• For developers, it means Ethereum-level creativity secured by Bitcoin’s trust. For users, it’s programmable Bitcoin without compromises.
• Bitlayer is paving the way for Bitcoin’s next chapter - one where it is not only digital gold but also the foundation for a new wave of decentralized innovation.
