#Bitlayer is a breakthrough Layer-2 network built on top of Bitcoin that brings Turing-complete smart contracts and high throughput to the Bitcoin ecosystem. In essence, Bitlayer acts like an “express lane” for Bitcoin: it processes transactions and decentralized apps off-chain in a fast Proof-of-Stake network, then periodically anchors the results to Bitcoin’s blockchain for security. As one Binance report notes, Bitlayer is “the first Bitcoin Layer-2 built on BitVM,” combining Turing-complete smart contracts with Bitcoin-level security. Industry sources describe it as a *“cutting-edge Layer 2 solution designed to enhance the scalability, speed, and efficiency of Bitcoin transactions”*. In short, Bitlayer unlocks new DeFi and Web3 capabilities for Bitcoin without sacrificing its security.@BitlayerLabs

BitVM-Powered Rollup: Bitlayer uses the BitVM paradigm – a hybrid of zero-knowledge proofs and optimistic fraud checks – to settle L2 state on Bitcoin. Rather than running complex code directly in Bitcoin (which isn’t possible), Bitlayer encodes state transitions off-chain and posts succinct proofs on-chain. The system assumes proofs are valid by default but allows anyone to challenge fraud through a dispute process. This design dramatically cuts on-chain cost and makes Bitcoin rollups practical.
