Bustabit Rust

bustabit is an utility library for verification of Bustabit games (bets and outcomes).

Bustabit is a provably fair game of luck. You can try the game on the official website: https://bustabit.com/

“Provably fair” means that: 1) the outcome of every game round has not been changed after players placed a bet, and 2) this statement could be verified and proven by any third-party.

Provably fair games rely on properties of cryptographic hash (one-way) functions. Bustabit’s Proof is more complex. In addition to independence of a game result, it proves the coefficient of game outcome, called “a bust”.

You may use it if you want to get historical busts, or analyze games happened previously. Also, it may be useful while testing and debugging your auto-playing scripts.

It is a pure Rust implementation of the 3rd party verification script: https://jsfiddle.net/Dexon95/2fmuxLza/embedded/result/

Benchmarks

This package also contains performance benchmarks done using Criterion. Run them using cargo bench.

Examples

For simple examples run cargo run --example nyans or cargo run --example simple.

Usage

extern crate bustabit;
// extern crate hex;

use bustabit::Game;


fn main() {
    // some game hash
    let s = String::from("b2acd37fbdb5509926ab5d7329704c840f8467266c90019682f3b260a029bdba");

    // create `Game` object from hash string
    let mut game:Game = Game::new(&s).unwrap();

    // iterate through 20 games occured before game with hash 'b2acd..bdba'
    for g in game.into_iter().take(20) {
        println!("{}", g); // print the Game object
        // println!("{}", game.outcome());  // print game outcome
        // println!("{}", hex::encode(game.hash)); // print game hash of current game
    }
}
