Package Exports

poseidon-lite
poseidon-lite/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (poseidon-lite) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

poseidon-lite

A stripped down poseidon implementation pulled from circomlibjs 0.0.8.

Use

// normal version
import { poseidon2 } from 'poseidon-lite'
// pass an array to the function
// array length must be equal to the function name
// returns a BigInt
const hash = poseidon2(['0x01', '0x02'])

// optimized version (larger bundle size)
import { poseidon2 } from 'poseidon-lite/opt'
// pass an array to the function
// array length must be equal to the function name
// returns a BigInt
const hash = poseidon2(['0x01', '0x02'])

Individual import

import { poseidon2 } from 'poseidon-lite/poseidon2'
const hash = poseidon2(['0x01', '0x02'])

// Optimized version
import { poseidon2 } from 'poseidon-lite/opt/poseidon2'
const hash = poseidon2(['0x01', '0x02'])

Normal vs Opt

This package includes two implementations of poseidon. The normal function and an optimized version with more pre-computed values. The normal function is ~3x slower than the opt version, but is also ~40% smaller.

Comparison of two input poseidon (poseidon2()):

Constants size
Normal: 12K
Opt: 20K

Speed
Normal: 243 hashes/second
Opt: 689 hashes/second
