Bitlayer is a next-generation Layer-2 blockchain built on top of Bitcoin, aiming to blend Bitcoin’s unmatched security with high throughput, programmability, and DeFi capabilities.

Based on the BitVM paradigm, Bitlayer enables Turing-complete smart contracts to run atop Bitcoin without undermining its security model.

It uses a recursive rollup settlement protocol, where continuous state transitions are verifiably anchored on Bitcoin’s mainnet. This ensures trustless operations while inheriting Bitcoin’s proof-of-work security.

The execution environment supports multiple virtual machines (e.g., EVM, MoveVM, CairoVM), offering flexibility and enabling developers to potentially port apps from other platforms.
