Hemi is a Layer 2 protocol designed to connect the Bitcoin and Ethereum networks, combining the security of the Bitcoin network with the flexibility of executing smart contracts like Ethereum.
Hemi's infrastructure includes the Hemi Virtual Machine (hVM), which integrates a Bitcoin node within an EVM-compatible environment (Ethereum Smart Contract Runtime Environment), allowing smart contracts on the Hemi network to access Bitcoin data (transactions, balances, UTXOs) directly.
