Simple proof-of-work library. Given an arbitrary string, it finds a nonce such that, when appended to the string, its BLAKE 3 hash starts with a given number of hexadecimal zeros.
By default:
use ebmus::Puzzle;
let difficulty = 5;
let template = "EBMUS:::"
let mut puzzle = Puzzle::new(template);
puzzle.solve(difficulty).unwrap();
println!("{}", puzzle.to_string()); // EBMUS:::1437302
println!("{}", puzzle.nonce); // 1437302
println!("{}", puzzle.hash()); // 000004c14153250a5234dfdca6a4a40c09ce8545fbe323463567631d05759516If you are using the "template" feature:
use ebmus::template::Template;
let template = Template::new("EBMUS"); // EBMUS: 1672169715:9doEQzRH3U76KKH2:::
let mut puzzle = Puzzle::new(template);
//...You can create your own custom template, as long as it implements the ToString trait. For example,
the "template" feature contains a Template struct defined by
struct Template {
name: String,
timestamp: i64,
token: String,
}which resolves to the string "EBMUS: 1672169715:9doEQzRH3U76KKH2:::".
- add documentation
- add tests
- instead of looking for hexadecimal zeros, find binary zeros.
