Overview
๐ TL;DR:
The Hemi Bitcoin Kit (hBK) enables direct interaction with Bitcoin blockchain data within Ethereumโs environment.
hBK utilizes Hemi Virtual Machine (hVM) to embed a fully indexed Bitcoin node inside the Ethereum Virtual Machine (EVM).
hBK allows Ethereum smart contracts to query Bitcoin data using precompiled calls, ensuring efficient, trustless data access.
โ๏ธ How It Works
Hemi Virtual Machine (hVM)
The hVM is the backbone of the hBKโs interoperability features, embedding a Bitcoin node within the EVM. This setup allows Ethereum smart contracts to directly query Bitcoin data without relying on external bridges or third-party oracles, ensuring trustless, efficient, and secure access to Bitcoin data.
Direct Access: Smart contracts can communicate with Bitcoin data embedded in the EVM, enabling them to make queries and receive data via precompiled calls.
Indexed Data: The fully indexed Bitcoin node maintains transaction history, UTXOs, and meta-protocols like Ordinals and BRC-20 tokens.
Developer Interface: Simplified Interaction with Bitcoin
The hBK abstracts technical complexities, offering developers straightforward methods for accessing Bitcoin data, allowing them to:
Directly Pass Data to Precompiled Calls: Simple data serialization/deserialization processes provide a transparent gateway to precompiled Bitcoin calls.
Enhanced Query Functions (Upcoming): hBK is set to introduce enhanced functions, combining multiple precompile calls and additional processing steps for advanced operations.
This dual approach ensures developers can create Bitcoin-aware applications without managing low-level integration details, focusing instead on innovation and functionality.
๐ Key Features
Embedded Node Access: hBK integrates a fully indexed Bitcoin node within Hemiโs EVM environment, exposing robust Bitcoin data for smart contract use.
Precompiled Calls for Direct Data Retrieval: Passthrough functions facilitate Bitcoin data queries with direct calls, automatically handling the data structures.
Enhanced Functions for Advanced Queries: Future upgrades will introduce enhanced functions, combining multiple calls and added processing to support more complex queries and data requirements.
