Bitlayer: The Layer 2 Solution Innovating the Bitcoin Ecosystem Bitlayer is a second-layer (Layer 2) protocol based on the Bitcoin network, aimed at enhancing the scalability and functionality of Bitcoin while preserving its core security and decentralization features. As the first Layer 2 solution based on BitVM (Bitcoin Virtual Machine), Bitlayer injects new vitality into the Bitcoin ecosystem by introducing support for Turing-complete smart contracts, cross-chain asset transfers, and efficient transaction processing. It not only addresses the low throughput and high fee issues of the native Bitcoin network but also attracts developers to build decentralized applications (dApp) through its compatibility with the Ethereum Virtual Machine (EVM).
