# Statistics
boha stats

# List puzzles
boha list
boha list b1000
boha list b1000 --unsolved
boha list b1000 --with-pubkey

# Show puzzle details
boha show b1000/66
boha show gsmg
boha show hash_collision/sha256

# Get key range
boha range 66

# Check balance (requires --features balance)
boha balance b1000/71

# Output formats (default: table)
boha -o json stats
boha -o yaml show b1000/66
boha -o csv list b1000 > puzzles.csv

Output formats

Library

use boha::{b1000, gsmg, hash_collision, Status};

let p66 = b1000::get(66).unwrap();
println!("Address: {}", p66.address);
println!("H160: {}", p66.h160.unwrap());
println!("Funded: {}", p66.start_date.unwrap_or("unknown"));

let range = p66.key_range().unwrap();
println!("Range: 0x{:x} - 0x{:x}", range.start(), range.end());

let unsolved: Vec<_> = b1000::all()
    .filter(|p| p.status == Status::Unsolved)
    .filter(|p| p.pubkey.is_some())
    .collect();

let gsmg_puzzle = gsmg::get();
let sha256 = hash_collision::get("sha256").unwrap();

let puzzle = boha::get("b1000/66").unwrap();
let puzzle = boha::get("gsmg").unwrap();

Balance fetching (async)

use boha::{b1000, balance};

#[tokio::main]
async fn main() {
    let puzzle = b1000::get(71).unwrap();
    let bal = balance::fetch(puzzle.address).await.unwrap();
    
    println!("Confirmed: {} sats", bal.confirmed);
    println!("Total: {:.8} BTC", bal.total_btc());
}
