Proof of Work Solver

This program solves such challenge:

sha256(MIa3OVQfKrrNBmpC + ???) == 00000000000000000000000000(26)

Installtion

  • Cargo crate publish: soon
  • Prebuilt: check release

Usage

Simply run:

# Example is given for the multi-threaded version
./solver-multi <prefix> <answer>

# Example
./solver-multi MIa3OVQfKrrNBmpC 26

You will get output like:

Answer is 90837933
Time elapsed in solve() is: 6.1497339s

Performance

For our example problem given above:

CPU Intel(R) Core(TM) i5-10500H CPU @ 2.50GHz

Benchmark 1: .\solver-multi.exe MIa3OVQfKrrNBmpC 26
  Time (mean ± σ):      7.094 s ±  0.090 s    [User: 77.039 s, System: 0.110 s]
  Range (min … max):    7.033 s …  7.341 s    10 runs

Benchmark 2: .\solver-single.exe MIa3OVQfKrrNBmpC 26
  Time (mean ± σ):     29.534 s ±  0.131 s    [User: 25.044 s, System: 0.015 s]
  Range (min … max):   29.290 s … 29.744 s    10 runs

So just use the multi-threaded one, and allow your computer to be laggy for a short period of time.

Credits

I was going to use RobinJadoul/proof-of-work but it has no rust version, my PC has no golang environment, and it's single-threaded.

So I worked with ChatGPT and made a Rust version.
