Hemi is a breakthrough modular Layer-2 blockchain protocol that seamlessly merges Bitcoin’s rock-solid security with Ethereum’s versatile programmability by embedding a full Bitcoin node into an Ethereum-compatible EVM, known as the Hemi Virtual Machine (hVM). This architecture allows developers to write Solidity smart contracts that natively access Bitcoin data without relying on bridges or synthetic assets. Using its proprietary Proof-of-Proof (PoP) consensus, Hemi achieves “superfinality,” anchoring transactions in Bitcoin blocks for high integrity and resistance to reorgs, all while maintaining fast finality. Its Hemi Bitcoin Kit (hBK) gives developers the tools to build truly Bitcoin-powered DeFi applications, such as lending, staking, automated market makers, MEV systems, and multi-chain DAOs, using real BTC as collateral or yield sources.
