chiabip158

What it is and what it does

chiabip158 is a Python wrapper around a C++ implementation of BIP 158, the Bitcoin Improvement Proposal standard for compact block filters. It provides the core algorithm for constructing and working with block filters—a space-efficient way to represent which transactions are in a block without transmitting the full block data. This is foundational infrastructure for lightweight blockchain clients and indexing systems.

The package is maintained by the Chia Network and serves as a reference implementation and building block for BIP 157 support (which adds a network protocol for distributing these filters). It has no Python runtime dependencies, relying entirely on its compiled C++ core. Installation is straightforward on modern Python versions via prebuilt wheels, though older Python versions may require a C++ compiler and build tools.

Use it for:

• Building lightweight blockchain clients that need to filter blocks without downloading full block data
• Implementing block indexing systems that construct and store BIP 158 filters for historical blockchain data
• Developing BIP 157 network protocol support to serve block filters to other clients
• Cryptocurrency wallet applications that need efficient block scanning without full node overhead
• Blockchain analysis and research requiring compact filter generation and querying

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Implements the BIP 158 compact block filter construction algorithm, providing a C++ backend wrapped for Python to generate and work with block filters for blockchain applications.

Yes, if you are building or contributing to Chia blockchain infrastructure or implementing BIP 158/157 support. The package is actively maintained, has no external dependencies, and offers prebuilt wheels for modern Python versions. Install friction is moderate but manageable. Not relevant for general-purpose Python development outside blockchain contexts.

Quickstart

pip install chiabip158

import chiabip158
# Use the module's filter construction functions as documented in the repository

Requires Python 3.7 or later; prebuilt wheels available for modern Python versions. Older Python versions may require compilation from source.

Verify before relying

• What specific functions or classes are exposed by the module for filter construction and querying
• Whether the package is actively used in production Chia blockchain deployments or remains primarily a reference implementation
• Performance characteristics and filter size/speed trade-offs compared to alternative implementations
