Poulpy 0.10.0Apache-2.0Rust
Poulpy is a backend agnostic modular Rust library for Fully Homomorphic Encryption over the Torus.
Why Poulpy
Write your application once, validate it with portable backends, and deploy it on specialized hardware. Choose the API level that fits your work, from polynomial arithmetic to complete FHE schemes.
Express your application through backend-independent APIs. Keep the computation as your hardware changes.
Write Rust code that is generic over the backend. Poulpy separates the operations your application calls from their execution, so a compatible backend can target different hardware without rewriting your application logic.
Explore the architecture →Develop and check your application with portable backends before moving to specialized hardware.
Validate your computation with portable backends before deploying it on specialized cloud hardware.
Explore the architecture →Use CKKS or Binary FHE, build with GLWE operations, or work directly with HAL arithmetic.
Choose the level of abstraction that you need to build your application.
Explore the architecture →Define your arithmetic setup once, then tailor scale and computation budget to each circuit with base-2ᴷ.
Conventional RNS rescaling follows a prime chain chosen at setup. Poulpy separates that setup from the circuit’s scaling schedule: base-2ᴷ lets you choose modulus widths and rescaling amounts directly in bits.
Benchmark
CKKS bootstrapping at N = 2¹⁶ restores 15 net levels at scale 2³⁵ with at least 19 bits of precision. Compare CPU backends on an AMD Ryzen 9 9950X and an Apple M5 Pro, and GPU backends on an Apple M5 Pro, an AMD Radeon RX 7900 XTX and an NVIDIA RTX 5090.

Private information retrieval
Query database records privately with the InsPIRe protocols. Includes eth-pir for private Ethereum token balance lookups and a browser demo for USDT and USDC.
Compiler
Compile encrypted computations to Poulpy Rust code through an MLIR-based FHE compiler.
Bindings
Use encrypted integer arithmetic from Rust, a browser, or Node through WebAssembly and native bindings.
