Function estimateDifficulty

estimateDifficulty(options): number

Estimate a VDF difficulty (iteration count) for a target wall-clock delay.

Results are approximate. Hardware, JS engine, and thermal throttling vary. For Pietrzak, the value is forced even and clamped to [66, 7000].

Parameters

options: EstimateDifficultyOptions

Returns number

Example

import { estimateDifficulty, WesolowskiVDFParams, DISCRIMINANT_256 } from 'crypto-vdf';

const difficulty = estimateDifficulty({ bits: 256, targetSeconds: 2 });
const vdf = new WesolowskiVDFParams(256).new();
const proof = await vdf.solve(challenge, difficulty, DISCRIMINANT_256);
