bn254 0.1.2

Pure-Python library that implements operations over the BN(2,254) pairing-friendly curve.

Pure-Python library that implements operations over the BN(2,254) pairing-friendly curve.

Usage Examples

This library is available as a package on PyPI. Usage examples are provided below:

from bn254.curve import r as scalar_upper_bound
from bn254.ecp import generator as base_point
from bn254.ecp2 import generator as random_point
from bn254.big import invmodp, rand
from bn254.pair import e

P = random_point()
G = base_point()
s = rand(scalar_upper_bound)
t = rand(scalar_upper_bound)
s_inv = invmodp(s, scalar_upper_bound)
b = s_inv * t

assert(
    e(t*P, G) == e(s*P, b*G)
)
