POWlib

POWlib is a pure rust library for scrypt-based proof-of-work challenges.
It uses 32-byte long scrypt hash with following parameters: log_n: 6, r: 64, p: 1

Example usage

To load an existing challenge: you may use powlib::gen::POWChallenge { hash: [a 32-byte long hash], range: POWRange::new(min, max) }
To generate a challenge, use this: powlib::gen::POWChallenge::make(POWRange::new(min, max))
To solve a challenge, use this: challenge.solve_singlethread()

Threaded solve method is planned but if you want to implement your own, there is a chunked method for solving: challenge.chunk_solve(min, max)

So, the simplest code would look like this:


use powlib::{self, gen::{POWRange, POWChallenge}};

fn main() {
    let challenge = POWChallenge::make(POWRange::new(0, 20480));
    println!("{}", challenge.solve_singlethread());
}

Examples

To run examples that have their own directory, cd to their directory and run cargo r. Like this:

$ cd examples/multithreaded
$ cargo r --release # debug version will be much slower
