It provides the core algorithm for constructing and working with block filters\u2014a 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.\n\nThe 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.","worth_installing":"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."},"id":"chiabip158","links":{"html":"https://skillfed.io/packages/chiabip158","md":"https://skillfed.io/packages/chiabip158.md","pypi":"https://pypi.org/project/chiabip158/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-11-06","license_spdx":null,"license_treatment":"permissive","name":"chiabip158","python_support":"supports_current","summary":"Chia BIP158 (wraps C++)"},"popularity":{"monthly_downloads":427269,"position":6752,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.5.4"}
