Bitlayer is a Layer-2 scaling solution designed for the Bitcoin network, aimed at enhancing its scalability, programmability, and efficiency while preserving Bitcoin’s core security and decentralization. It leverages the Bitcoin Virtual Machine (BitVM) paradigm to enable smart contract functionality and decentralized applications (dApps) on Bitcoin, which traditionally focuses on peer-to-peer transactions. Below is a comprehensive overview based on available information:
What is Bitlayer?
Bitlayer is a Bitcoin Layer-2 protocol that addresses Bitcoin’s inherent limitations, such as low transaction throughput, high fees, and lack of native smart contract support. It introduces Turing-complete programmability, allowing developers to build complex dApps and smart contracts on Bitcoin, similar to Ethereum’s capabilities. Bitlayer achieves this by combining BitVM, Zero-Knowledge (ZK) Proofs, and a Layered Virtual Machine (LVM) architecture, ensuring Bitcoin-equivalent security and interoperability with other blockchains, particularly Ethereum via full EVM (Ethereum Virtual Machine) compatibility.
Key Features and Innovations
Scalability:
Bitlayer processes transactions off-chain using a rollup architecture, batching them before settling on Bitcoin’s main chain. This reduces congestion, lowers fees, and increases throughput, with plans to achieve 20,000 transactions per second (TPS) and 3-second block confirmations by Q4 2025.
It uses ZK Proofs and state channels to enable efficient off-chain transaction processing while maintaining security.
Smart Contract Support:
Through BitVM, Bitlayer enables Turing-complete smart contracts, allowing complex dApps like DeFi protocols, gaming platforms, and NFT marketplaces to run on Bitcoin.
Its EVM compatibility (up to Ethereum’s Cancun update, with some limitations) allows Ethereum developers to port applications using familiar tools like Solidity (up to v0.8.28) and MetaMask, reducing barriers to entry.
Trustless Cross-Chain Bridging:
Bitlayer’s BitVM Bridge and Optimistic Discreet Log Contract (OP-DLC) enable secure, trust-minimized asset transfers between Bitcoin and other blockchains (e.g., Ethereum). This avoids reliance on centralized custodians, enhancing interoperability and liquidity.
Bitcoin-Equivalent Security:
Bitlayer inherits Bitcoin’s security by verifying Layer-2 state transitions on Bitcoin’s base layer using BitVM-based proofs. This ensures dApps and transactions benefit from Bitcoin’s robust consensus without altering its core design.
Layered Virtual Machine (LVM):
The LVM separates smart contract execution (front-end) from ZK proof generation (back-end), improving efficiency and security. This allows complex computations while maintaining Bitcoin’s integrity.
Flexible Data Availability:
Users can choose between Bitcoin-native or third-party data availability solutions, balancing cost and decentralization.
Bitlayer’s Token: BTR
Token Name: BTR (Note: Some sources mention a $BTL token, but BTR is more consistently referenced as the native token).
Total Supply: Fixed at 1 billion BTR tokens (some sources mention 2.1 billion for $BTL, indicating possible discrepancies or different token plans).
Functions:
Governance: BTR holders can vote on ecosystem proposals and influence platform development.
Incentives: Rewards developers, users, and participants to drive ecosystem growth.
Staking: Used to secure the network and participate in DeFi activities.
Tokenomics:
80%: Allocated for liquidity and smart contract execution.
15%: Supports ecosystem development, marketing, and community initiatives.
5%: Reserved for advisors and exchange listings.
Token Sale: A sale occurred on platforms like CoinList and Holdstation Launchpad (Aug 7–11, 2025), with a price of $0.20 per BTR and a fully diluted valuation (FDV) of $200M. The token is expected to unlock fully one year after the Token Generation Event (TGE) in Q3 2025.

Total Value Locked (TVL): Surpassed $725M in 2024, indicating significant ecosystem growth.
Roadmap
Bitlayer’s development follows a three-phase plan:
Phase 1: PoS (Mainnet V1) – Launched April 2024, combining Proof of Stake (PoS) with multisig for security and EVM compatibility.
Phase 2: Bitlayer Rollup (Mainnet V2) – Planned for Q1/Q2 2025, transitioning to a BitVM-based rollup with trust-minimized bridging and Bitcoin-native security.
Phase 3: Supercharged Rollup – Targeted for Q4 2025, aiming for 20,000 TPS, 3-second confirmations, and enterprise-grade applications.
Vision and Goals
Bitlayer’s mission is to scale Bitcoin while maintaining its decentralization and security, transforming it into a robust platform for Bitcoin DeFi (BTCFi) and diverse applications. It aims to:
Enhance transaction speed and reduce costs.
Enable asset diversity (e.g., tokens similar to Ethereum’s ERC-20).
Foster innovation through developer-friendly infrastructure.
Drive broader Bitcoin adoption via interoperability and low-cost dApps.
