Bitlayer is a Bitcoin Layer 2 solution designed to bring smart contract functionality and enhanced scalability to the Bitcoin ecosystem. It utilizes a novel architecture that combines a BitVM-based rollup with an EVM-compatible execution layer, allowing developers to build and deploy complex applications, including DeFi protocols, on top of Bitcoin's secure network. By processing transactions off-chain and then settling them on the Bitcoin mainnet, Bitlayer significantly increases transaction speed and reduces costs while inheriting Bitcoin's core security features. The platform aims to transform Bitcoin from a simple store of value into a programmable asset, unlocking its potential for a new generation of decentralized applications.
