Accelerated operations for BN254

Project description


Accelerated operations for BN254 using libff and libfqfft.

Supported operations:

  • Multi-exponentiation in G1
  • FFT
  • Multiply polynomials

Install for pip

  • pip install pybn254


Install python dependencies


  • py_ecc

Compile native dependencies


  • Install Homebrew
  • Install dependencies - brew install gmp boost cmake openssl libomp
  • Go into libff and run make all

This should create libff.dylib in the root folder.


  • Install dependencies - sudo apt-get install build-essential git libboost-all-dev cmake libgmp3-dev libssl-dev pkg-config
  • Go into libff and run make all

This should create in the root folder.


You can use the following script to test things out:

import pybn254

from py_ecc.optimized_bn128 import add, multiply, pairing
from py_ecc.fields import optimized_bn128_FQ as FQ

p = [(FQ(1), FQ(2), FQ(1))]
e = [5]

p1 = [1, 2, 3]
p2 = [4, 5, 6]


# run fft, not an inverse, not on a coset
print(pybn254.fft(p1, False, False))
print(pybn254.multiply_polynomials(p1, p2))
