@BitlayerLabs #Bitlayer What Is Bitlayer?
Bitlayer is an innovative Layer-2 protocol for Bitcoin, designed to bring smart contract capabilities, high throughput, and EVM compatibility to the Bitcoin network—all while inheriting its rock-solid security.
Built around BitVM (Bitcoin Virtual Machine), Bitlayer acts like an optimistic rollup on Bitcoin, enabling Turing-complete smart contracts.
It pairs BitVM with Zero-Knowledge (ZK) proofs, allowing batching of off-chain transactions and efficient, secure validation.
Crucially, Bitlayer secures its state transitions by anchoring them directly onto Bitcoin’s L1 chain, safeguarding them with Bitcoin’s consensus and ensuring “hard finality.”
Key Technical Highlights
Turing-Complete Execution Engine: Offers compatibility with multiple virtual machines (e.g., EVM, CairoVM), making it easier for developers to deploy decentralized applications.
Fast Finality with Dual Layers:
Soft finality: Near-instant confirmation via PoS-based block production.
Hard finality: Achieved when L2 state is validated on Bitcoin, typically over a challenge period.
Trust-Minimized Asset Bridge (BitVM Bridge): Enables secure BTC bridging without federated custody, using optimized DLC and fraud-proof mechanisms.
EVM Compatibility and dApp Ecosystem: Bitlayer supports EVM-style development and already hosts DeFi, gaming, NFT, lending, and launchpad applications.
Ecosystem and Funding Overview
Founded in October 2023, Bitlayer Labs is already backed by major investors including Polychain Capital, OKX Ventures, and Franklin Templeton Investments.
The platform facilitates cross-chain liquidity, with BitVM bridges integrated with prominent networks like Base, Arbitrum, Starknet, Sui, and more.
