Merlin Chain is Bitcoin's Layer 2, integrating ZK-Rollup network, decentralized oracle network, data availability and on-chain BTC fraud proof modules. Merlin Chain is committed to empowering Bitcoin's Layer 1 native assets, protocols and products through its Layer 2 network to make Bitcoin interesting again. Merlin Chain uses zero-knowledge proofs submitted to Bitcoin to verify commitments, providing enhanced support for the Bitcoin network. It allows challengers to propose fraud proofs on disputed matters, using Bitcoin's powerful consensus mechanism to ensure the security of the Merlin Chain network. This ensures that users within the ecosystem have a safe, practical, comprehensive and cost-effective network environment. Merlin Chain aims to extend the native innovation of Bitcoin Layer 1 to Layer 2. This includes supporting a variety of Bitcoin Layer 1 assets, building dApps with Bitcoin's "fully on-chain" spirit, and a community-driven asset release method. Merlin is trying to build an EVM-compatible chain for Bitcoin to unleash the potential of Bitcoin and Ordinals.

Merlin Chain provides Bitcoin's most advanced zero-knowledge (ZK) expansion solution with the following advantages: - Security: Inherits Bitcoin's security while providing additional advantages in L2 batch scalability. - EVM compatibility: Supports most existing smart contracts, developer tools, and wallets to ensure seamless interoperability. - Low cost: Utilize ZK proofs combined with zkSNARKs to reduce L1 space consumption and optimize users' transaction costs. - High performance: Fast network finalization through frequent validity proofs and ultimate scalability through recursive STARKs.
