Pollard's kangaroo ECDLP solver

[WanderingPhilospher]

It's likely @Tesorex refer to @Jean_Luc (OP of this thread).

However, this does not make sense to me. Because the thread creator JLP explicitly refers to his Github repository where you'll find a documentation and explanation of how to use the tool.

Concur; JLP did an above and beyond explanation of how to run the program and about the theory behind Pollard's Kangaroo method.

A Beginner's Guide to the Windows Command Prompt. IMO current documentation is targeted towards geek, power user and developer.

Wow thank you my man, now which version of ubuntu should I install, good thing I frequent cracking projects😀, do I need ubuntu to run kangaroo? Because running in windows, setting all the arguments, the bat file opens and closes very fast, it seems like nothing works, maybe I should run it using cmd? isn't bat file doing the same thing though? When I dowmload kangaroo, I should place it in a folder and create a bat file or just run cmd and insert the option inftont of the kangaroo.exe? And which commands should I use, I currently have Geforce nvidia 920MX intel inegrated gpu.

Should I install 18 or 20 or 22 version from windows store?

If you are using a batch file, it's easy to stop and see what the error is.

Add a pause on the second line of your batch file, like this:

Kangaroo.exe -t 0 -d 12 -gpu -g 20,256... etc.
pause

I don't know how to set a proper command in the batch file, what do use yourself, could you give me the whole correct command? I will change my specifics to meet my system config, thank you. Also isn't this kangaroo used to find addresses with known public keys? If that's the case and there are no more public keys left in the puzzle challenge, I don't want to use it, not interested  in cracking keys which are not mine.

Hi there  to all

Congratulations to the person who solve the Puzzle #120 

I wonder which is the private key.

[dextronomous]

wowie nicer things happening finally.

now tell us who you are..

[Lolo54]

Wonderful performance congratulations
It will have taken more than 2 years to find it.
I'm curious to know the privateKey and whether it's bruteforcing (kangaroo solver/bsgs/bitcrack etc...) or some other way to find it?
Congratulations

So cool to see that there is still success in the Bitcoin puzzle. Would be interesting to know how much time and effort was put into solving, and compare it to the reward. Maybe the solver will explain it some day 

[digaran]

Guys please give the man/ woman some time, they need to cash out every single bitcoin fork/ altcoin before revealing the private key. I'd like to add that there is no known method other than log problem to solve in order to find the key in high bit ranges. Way to go who ever you are.🥳🥳🥳🤑🤑🤑

[NotATether]

Forgive me to be the intruder guys, can someone explain briefly what's this puzzle solving thing about and what does it mean for the network for a completely unaware but curious bitcoin user? :')

Someone made a bunch of transactions using successively larger keys to see if people would be able to crack them. Each transaction has a private key of successively higher bitlength (increases by one). The range of the keyspaces was also made known to see how quickly people would brute force and find the key.

[Grantrocks]

pretty much means free money if you can crack one. Its really just there to test/prove how secure bitcoin is

Hi guys, any news about who solve p64 and p120 ?

I just want to know the hardware that they use, this only to make calculations about how much will cost solve the p66 and p125.

"I just want to know the hardware that they use,"

Answer: you wil never know ... Sorry

"how much will cost solve the p66 and p125"

Answer: Cost is much MUCH more than the prize of 0.66 or 1.25 BTC .... Sorry

Hello, if my list of pubs more 1 million or more 500 millions can i use kangaroo?
are they all checked at the same time or in turn?

One at a time, or in turn as you call it.

Hello Kangsolvers, have you ever thought about using chat GPT to try to reduce search space based on patterns, using Fermat or regression methods for sequences? Does anyone know if there is any intuitive material about the code? I couldn't find any cool videos on YouTube, only one where the guy runs it on a cloud using processing power from multiple GPUs. I would like to produce some content in this direction and bring more Kangsolvers to the team, and maybe focus more on demystifying how difficult it is to find a key. Sometimes I show sites like privatekeys.pw to a friend, and they actually believe they can just click from page to page and become millionaires by chance.

Anyway, jokes aside, I've been thinking about a possible withdrawal scenario. Let's say I find a key, hooray! Now what? What are the concerns about sending it to Binance, swapping it for dollars, and cashing out? This is obviously different in the case of puzzles.

I'm exploring some ideas and running with limited hardware here, more for studying purposes. But who knows, right? I mean, we do know, it's like a grain of sand on Jupiter lol.

Anyway, I plan to share my results and ideas here, hopefully it will be useful for newcomers, from one noob to another, lost in the secp256.

Hi Puzzle hunter,

The puzzle 120 was found using this method:
https://github.com/demining/CryptoDeepTools/tree/main/06KangarooJeanLucPons

#120, 119bits private key [2119,2120-1], 17s2b9ksz5y7abUm92cHwG8jEPCzK3dLnT 1.20BTC

800000000000000000000000000000
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
02CEB6CBBCDBDF5EF7150682150F4CE2C6F4807B349827DCDBDD1F2EFA885A2630
Expected time: ~2 months on 256 Tesla V100.

256 GPU card x 60 days x 24h x 300watts = 110 592 kwh x 0.03$ = 3317$ electricity bills but 256k$ of gpu card ;-)

#125 will be this year too i think

Hi Puzzle hunter,

No, it wasn't. It was found using Kangaroo from JeanLucPons and the original software and source is
https://github.com/JeanLucPons/Kangaroo

Warning at this point: if you don't trust this user and the repository he links to, don't run any code from him if you don't know what the code does. If in doubt, use the original software from JLP and not any forks that you are not sure contain malicious code.
