How hVM and hBitVM work (simplified):
🔹 hVM (Hemi Virtual Machine)
The hVM is a specialized execution layer that runs inside the Ethereum Virtual Machine (EVM) but includes a fully indexed Bitcoin node.
What this enables:
🧠 Bitcoin-aware smart contracts
🧾 Solidity contracts can directly read Bitcoin data (UTXOs, transactions, block info)
🚫 No need for oracles, relayers, or third-party feeds
How it stays secure:
All Hemi nodes maintain a synchronized “Processed Bitcoin View”
This guarantees deterministic results—every node sees and verifies the same Bitcoin state
Bitcoin effectively behaves like a native data layer for DeFi apps
Result: ➡️ Developers can build BTC-native DeFi using familiar EVM tooling, with trust minimized.
🔹 hBitVM (Hemi Bitcoin Virtual Machine)
The hBitVM is the security and bridge layer connecting Bitcoin and Ethereum through Hemi.
What it does:
Secures cross-chain “Tunnels” between BTC and ETH
Handles asset locking, verification, and dispute resolution
Security model:
Built on BitVM2
Uses a 1-of-N honesty assumption
Funds remain safe as long as one participant behaves honestly
Why it matters:
🔐 No centralized custodian
⚖️ Fraud-proof design for cross-chain transfers
🧱 Strong security guarantees using Bitcoin’s own scripting limits
🧩 Big Picture
hVM = Execution + Bitcoin data access
hBitVM = Security + BTC↔ETH bridging
Together, they turn Bitcoin into an active, programmable participant in DeFi—without sacrificing decentralization.
