“From Linux to Bitcoin to Hemi, my mission has always been building infrastructure that lasts.”
Jeff Garzik
Principal Engineering, Hemi Labs
Co‑founder of Bloq. Lead engineer at Hemi. One of the original architects of Bitcoin itself. Jeff spent five years as a core Bitcoin dev and a decade shaping the Linux kernel — code that’s now embedded in every Android device and modern data center on Earth. His fingerprints are on two of the most important protocols of our time. Now he’s building the third.

Community & Participation FAQs
How can I get in contact with the Hemi team?
Email us directly at team@hemi.xyz for partnership or media inquiries.
Where can developers get started?
Developers ready to start building on Hemi can explore our developer docs and GitHub repositories.
How can I join the Hemi community?
Join our Hemi Discord to connect with contributors, get technical support, and participate in upcoming community calls.
Who is responsible for Hemi?
Hemi is built and maintained by Hemi Labs with contributions from independent developers, node operators, and ecosystem partners.
What is Hemi?
Hemi is a dual-layer protocol that makes Bitcoin programmable. It combines Bitcoin’s Proof-of-Work security with Ethereum-level smart contract execution through the Hemi Virtual Machine (hVM) and Hemi Bitcoin Kit (hBK).
How does Hemi differ from other Bitcoin Layer-2s?
Hemi anchors every transaction to Bitcoin via Proof-of-Proof (PoP), inheriting Bitcoin’s full security. Other L2s rely on bridges, wrapping, or hybrid validation. Hemi keeps assets and logic verifiable on-chain.
What is the hVM?
The Hemi Virtual Machine (hVM) is a full Bitcoin node wrapped inside an EVM. It lets developers deploy Solidity smart contracts that directly interact with Bitcoin data.
What is the hBK?
The Hemi Bitcoin Kit (hBK) allows contracts to read and verify Bitcoin state including UTXOs, headers, and balances, inside Solidity. It brings real Bitcoin awareness to smart contracts.
How is Hemi secured?
All Hemi blocks are anchored to Bitcoin through Proof-of-Proof. This means Bitcoin miners indirectly secure the network. Every transaction can be traced back to Bitcoin’s Proof-of-Work chain.
How do I start building?
Follow the Quickstart guide or run the testnet demo: connect your wallet, claim test BTC/ETH, deploy your first contract in Remix, and query Bitcoin data using hBK.
