It is a cryptographic hash function designed for zero-knowledge proof systems and blockchain applications. The package compiles to native code for performance-critical hashing operations and is distributed as precompiled wheels for most common platforms (Linux, macOS, Windows across multiple architectures). With zero runtime dependencies, it integrates directly into Python applications that need Starknet-compatible hashing.\n\nThe package is actively maintained and supports modern Python versions (3.10 and later), with recent updates adding support for Python 3.13 and 3.14. Installation is straightforward on supported platforms via prebuilt wheels, though the compiled nature means some architectures may require local compilation. The Starknet parameter set is baked into the library, making it suitable for applications that specifically need Starknet-compatible hashing without configuration overhead.","worth_installing":"Yes, if you need Starknet-compatible Poseidon hashing. The package is actively maintained, has no known vulnerabilities, zero runtime dependencies, and offers precompiled wheels for broad platform coverage. The main caveat is that the license status is unclear\u2014verify the licensing terms before use in proprietary contexts. Install friction is moderate due to compilation requirements on unsupported architectures, but negligible on common platforms."},"id":"poseidon-py","links":{"html":"https://skillfed.io/packages/poseidon-py","md":"https://skillfed.io/packages/poseidon-py.md","pypi":"https://pypi.org/project/poseidon-py/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-03-26","license_spdx":null,"license_treatment":"unclear","name":"poseidon-py","python_support":"supports_current","summary":"Python implementation of Poseidon hash"},"popularity":{"monthly_downloads":108704,"position":12542,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.2.0"}
