How Hemi connects the blockchain universe.

Hemi prioritizes security, accessibility, and trustless infrastructure for developers of interfacing protocols, with support for the engineering of powerful cross-chain applications. In addition, Hemi offers Ethereum’s flexibility and directly integrates Bitcoin-based assets without censorship or third-party custody. This fosters a truly trust-minimized on-chain ecosystem.

As an extension of the Ethereum network, the Hemi Virtual Machine (hVM) also contains a fully indexed Bitcoin node. With this, Hemi can natively sync Bitcoin data without relying on third-party oracles, ensuring a trust-minimized and seamless integration between the two ecosystems for decentralized applications.

Hemi’s Developer Suite

Hemi offers tools and resources that give developers the edge when designing their apps:

Developer Quickstart Guide—Jumpstart the building journey with an overview of the necessary steps and resources to begin building on Hemi. Perfect for blockchain beginners and experienced Web3 devs alike.

Hemi Bitcoin Kit (hBK)—Study the smart contracts designed to bridge Ethereum and Bitcoin networks, empowering Bitcoin-aware decentralized applications in an EVM state, with full access to assets from both ecosystems and cross-chain data calls.

Hemi Tutorials—Explore tutorials for smart contract deployment, contract verification, and Bitcoin balance management tools.

GitHub Resources—Access Hemi’s official GitHub, which hosts several repositories, documentation, and tools to build on the network.

Hemi’s Tech Stack—Review the architecture and components behind Hemi, and see how it facilitates a unified sovereign, secure, and interoperable blockchain ecosystem.

Hemi Nodes Provide Participants With Many Ways to Earn 

Hemi opens up the floodgates for developers to leverage Bitcoin’s liquidity in a more programmable and secure environment. With a hybrid consensus mechanism Proof-of-Proof, Hemi validates transactions with a BFT PoS-based authentication protocol that inherits robust security from Bitcoin’s PoW work. Once a block of transactions are verified via PoS they are bundled, hashed, and sent to Bitcoin, to be confirmed on Bitcoin blocks by PoP miners, creating a verifiable link between the two networks for Hemi to achieve superfinality.

The multifaceted nature of Hemi’s consensus protocol offers participants numerous opportunities to earn value while securing the ecosystem, with four different specialized nodes that work together to facilitate the network’s hybrid consensus model:


Bitcoin Secure Sequencers (BSS Nodes)—Earn rewards by securely ordering Hemi transactions while leveraging Bitcoin’s security layer.


PoP Mining—Earn rewards for each successful block validation anchoring transaction data to Bitcoin’s blockchain.

Bitcoin Finality Governers (BFGs)—Earn rewards by ensuring transactions sent to Bitcoin achieve finality.

Challengers—Earn rewards by monitoring the state of proofs and correctness of transactions.

Hemi gives participants the power to shape the future of cross chain DeFi, support a robust security protocol, and drive innovation throughout blockchain ecosystems. With comprehensive developer tools, trust-minimized infrastructure, and multifaceted engagement surface, Hemi is ready to offer a powerfully interoperable decentralized ecosystem.
