Is there a new kangaroo program that actually works?
The original is limited to 125 bits. Other modded kangaroos are mostly not working.
Is there a kangaroo that works for sure that we can use for puzzle 130 and above?
Did you actually searched for one and nothing came up? You can use nomachine's Rust Kangaroo a few posts back, or write a Python script that does the job according to your requirements (e.g. "that actually works").
Too slow? Well, don't expect to find something that "actually works", is fast, and solves 130, sitting out there for you to snug up and inherit 13 BTC tomorrow.
My best (private) CUDA kangaroo is a few times faster than any JLP-based clone, and even so I still estimate the cost to break #130 around at least $100.000 with 6 months of processing on top-end Nvidia GPU renting, and this only to collect the DPs (e.g. ~2**65 group operations). It's by no means easy to write and optimize something like this, it requires a lot of time investigating resource limits and algorithmic bottlenecks to squeeze out close to 100% CUDA peak performance. If I break 130 I will publish the stuff on GitHub, until then I'm done with giving out clues about how I achieved these performance improvements. The only thing that can beat this would be a FPGA with lots of transistors.
I think you misunderstood the situation very much. I think that kangaroos that have been forked or modded from JLp's original kangaroo do not work. and I'm really asking about kangaroo running on 125 bit and above.
Think of a program that you have been running for months, but you have actually run it in vain due to code errors. How would you feel in this situation?
For example, the keyhunt bsgs program is a program that definitely works.
For example, Jlp kangaroo original version 125 works, it definitely works.
What I want is a perfectly updated kangaroo with no bugs.
But if you want to know if one program really works, just choose a private key in 130bits range, get the public key and run the program against that.. you will know if it works or not.
