# chiapos — Chia proof of space plotting, proving, and verifying (wraps C++)

License: permissive · Maintenance: active · Downloads: 445.6K/mo

## What it is and what it does

Chiapos is a Python wrapper around Chia's proof-of-space implementation, a cryptographic primitive used in Chia blockchain consensus. It provides three main operations: creating plots (generating proof-of-space files), proving (generating proofs from a challenge), and verifying (validating proofs). The package is written in C++ for performance and compiled to wheels for multiple Python versions and platforms.

The library runs exclusively on 64-bit architectures and requires Python 3.7 or later. It has no runtime dependencies beyond the compiled C++ backend. The repository includes both Python and Rust bindings, though Rust bindings are limited to proof verification only. The package is actively maintained, with the main branch tracking the latest released version on PyPI.

Use it for:

- Creating proof-of-space plots for Chia blockchain farming or testing consensus mechanisms
- Verifying proofs of space in applications that need to validate Chia-compatible proofs
- Benchmarking or researching proof-of-space performance on different hardware
- Integrating proof-of-space verification into Python applications requiring Chia compatibility
- Experimenting with Hellman Attacks for space-optimized plot generation

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Python bindings for Chia's proof-of-space implementation, providing plotting, proving, and verification of proofs of space via a C++ backend.

Yes, if you need proof-of-space plotting or verification for Chia blockchain work. The package is actively maintained, has no known vulnerabilities, supports modern Python versions with prebuilt wheels, and carries a permissive license. Install friction is moderate due to C++ compilation, but prebuilt wheels mitigate this for common platforms. Not relevant for non-Chia use cases.

## Install

pip install chiapos
uv add chiapos
poetry add chiapos

## Installing chiapos

Before you install: Medium install friction due to compiled C++ bindings; wheels are available for multiple Python versions on macOS (arm64 and x86_64), Linux (aarch64 and x86_64), and Windows. Repository is active with recent commits and no archived status.

License in practice: Licensed under Apache-2.0 (permissive), allowing commercial and private use with minimal restrictions beyond attribution and liability disclaimers.

Quickstart:

pip install chiapos

import chiapos
# Use the module's plotting, proving, and verification functions as documented in the repository

Requires a 64-bit architecture; Python 3.7 or later; C++ runtime for compiled bindings.

Verify before relying:

- Specific Python API surface and function signatures for plotting, proving, and verification
- Performance characteristics and typical plot file sizes
- Whether Rust bindings support proof verification only or full plotting capability
- Exact Python versions supported by prebuilt wheels beyond what version strings indicate
