Overview
• Bitlayer is not just another Layer-2—it’s Bitcoin evolved.
• Built on the BitVM paradigm, it adds smart contract functionality and scalability to Bitcoin, without touching its core protocol.
• Think of it as a high-security, high-performance sandbox where Ethereum-compatible apps can run using Bitcoin’s unmatched base-layer trust.
Core Offerings
• Smart Contract Layer on Bitcoin
Using the Layered Virtual Machine (LVM), Bitlayer supports EVM (Solidity) and even alternative runtimes like CairoVM. A familiar environment for Ethereum devs, powered by Bitcoin security.
• Optimistic + ZKP Hybrid Execution
Bitlayer handles off-chain computations; rollups submit compact state transitions validated on-chain with fraud-proof ZK mechanisms.
• Native BTC Bridge via BitVM
The BitVM Bridge allows trust-minimized, two-way transfers of Bitcoin and wrapped assets to and from Bitlayer, using OP-DLC and fraud proofs—no custodians needed.
Technical Edge
• Bitcoin-Level Security Without a Fork
Bitlayer submits state proofs directly to Bitcoin’s main chain and is secured by real mining power—30% of the hashrate actively supports BitVM execution today, including Antpool, F2Pool, and SpiderPool.
• Modular Rollup Blueprint for BTC
Reminiscent of Ethereum’s rollups, it batches transactions via a sequencer, processes with LVM, and publishes proofs to L1—now with flexible data availability options for cost or security optimization.
• Extending Across Chains
Bitlayer is plugging Bitcoin assets into DeFi ecosystems on Base, Starknet, Arbitrum, Sonic, and Plume—real interoperability, real momentum.
Innovations & Ecosystem Momentum
• Bitcoin-Native Rollup, Not a Sidechain
Bitlayer V2 is evolving into a true Bitcoin rollup, not a detached sidechain. It inherits BTC’s security while offering EVM programmability.
• Trusted by DeFi Builders
Velar is using Bitlayer as the backbone for its Bitcoin-native PerpDex, combining deep computing with Bitcoin resilience.
Why It Matters
• Bitlayer finally unlocks Bitcoin’s $1.9 trillion capital for DeFi, gaming, NFTs, and smart contracts—without compromising trust or decentralization.
• For developers, it’s Ethereum tools backed by Bitcoin firepower. For users, it’s secure, programmable Bitcoin for the Web3 era.
