Overview
Bitlayer brings real programmability to Bitcoin without altering its core consensus. Built on the BitVM paradigm, it layers smart contract capability, optimistic execution, and zero-knowledge proof verification over Bitcoin. This creates a modular, high-throughput Layer 2 where developers can deploy EVM and CairoVM-compatible contracts, all while preserving Bitcoin-level security. 
Core Offerings
• Layered Virtual Machine (LVM): Adapt Solidity, Cairo, and other languages into Bitcoin-native contract execution environments. Executed off-chain, then verified on-chain via ZK proofs.
• Optimistic + ZK Verification: Combines optimistic rollup mechanics with fraud-proof ZK resolution—challengers can dispute faulty batches and proofs are enforced.
• BitVM Bridge: A trustless, two-way bridge leveraging BitVM capabilities to connect BTC with EVM chains, enabling secure asset transfers and interoperability.
Technical Edge
• Deep Bitcoin Anchor: All state transitions and proofs are recursively settled on Bitcoin, guaranteeing ultimate security via PoW.
• Sequencer Architecture: Executes L2 logic with sub-second soft finality and batched settlement, enabling responsive, high-performance decentralized applications.
• Hashed Community Backing: Antpool, F2Pool, and SpiderPool - controlling over 31.5% of Bitcoin’s hashrate - support Bitlayer’s BitVM Bridge, injecting real mining ecosystem legitimacy.
Innovations & Backing
• Bitcoin-Equivalent Security Without Forks: Bitlayer enables scalability and programming while preserving Bitcoin’s trust model intact.
• Multi-VM Support & DA Committee: Includes Ethereum and Cairo VM support, plus a Data Availability Committee to safeguard transparency.
• Expanding Multichain Reach: Bitlayer is forging interoperability with ecosystems including Base, Arbitrum, Starknet, Sonic, and Plume - unlocking BTC’s flow across Web3.
Why It Matters
Bitlayer doesn’t just layer functionality over Bitcoin - it redefines what Bitcoin can be: a foundational, programmable settlement layer for DeFi, gaming, NFTs, and more.
With native-like security, high performance, and mining ecosystem buy-in, Bitlayer may finally unlock Bitcoin’s $1.9T capital for programmable finance - without rewriting consensus.
