However old python code may be interesting if someone can use python connect and work with AI. tensor flow and Keras do deep learning work with kangaroo I mean modify to work beater

What has AI to do with finding the private keys? AI can not help at all with kangaroos.

I don't really know much

if we still use pure kangaroo , now we still stuck with high bits high range high keyspace

kangaroo need to jump a lot may be too many days jumps and jumps to new position scan

I don't know how kangaroo use pubkey XY to calculate but point XY use for calculate

Can possible to create dataset use method private key generate with public point and train AI to give some value and use kangaroo to get point to jump or do something like that ?
Use AI. predict key space and give it to kangaroo ?

Any idea?

still need to AI. expert help to analysist

Everyone just about knows of that old version of kangaroo with python already. We are on the new version of kangaroo that uses distinguished points (DP) method now.

Thanks
rights that old python code, I just use learning about how Kangaroo it works (easy to show how it work and read code on one files or print show display data how it works for use this tools better

For real use use JeanLucPons Kangaroo with GPU is faster

if anyone try using python script and require to use gmpy2 library

https://github.com/Telariust/pollard-kangaroo/blob/master/pollard-kangaroo.py
https://github.com/Telariust/pollard-kangaroo/blob/master/pollard-kangaroo-multi.py

or use BSGS and script use gmpy2
or other script generate bitcoin address and use gmpy2 to accelerate calculate for faster

use library gmpy2 make calculate faster

install gmpy2 on linux

need to install libgmp first after that then install gmpy2 normal

Code:

apt-get install libgmp-dev
apt-get install libmpfr-dev
apt-get install libmpc-dev

pip install gmpy2

install gmpy2 on anaconda (windows 10)
Anaconda Individual Edition or Miniconda
use conda install
command

Code:

conda install gmpy2

install gmpy2 on python windows 10
download gmpy2 from this url
https://www.lfd.uci.edu/~gohlke/pythonlibs/
choose version macth with you python version
example download
gmpy2‑2.0.8‑cp39‑cp39‑win_amd64.whl

How can we know what happen with higher bits or large range ?

I'm currently working on increasing the maximum range - when that's done I'll release the code so you guys can test this for yourselves.

@fx; the quick version. The kangaroo program basically creates wild and tame kangaroos. Both are set out to look for the distinguish point size you designate. So let's say you set dp to 20 (that will be a pubkey that has 5 leading zeros 0x00000; 5x4 = 20). Each time a dp is found, it is recorded in a hash table (the location and the distance traveled), if a tame visits a dp and a wild visits the same dp, then the key is solved. The kangaroos keep hopping around until a "collision" occurs when a tame and wild visit same dp (location).
Now, you talk about modifying it to not make it a kangaroo program, what would you want or change? Might be a better program to tweak to suit what you are looking for.

Thank you very very much WanderingPhilospher

you explain quick version and with image illustration on JeanLucPons Kangaroo github page now I understand better
https://raw.githubusercontent.com/JeanLucPons/Kangaroo/master/DOC/paths.jpg
first time I just read code and try understand

good to know how tools it works (better than use tools only)

How can we know what happen with higher bits or large range ?
may be start point long too much difference
I try to find what problem and fix that point

I think may be try to write code to save data to can read like image illustration plot graph

How 2 public point X, Y (from public key) use to calculate on Kangaroo?

I think I need to more learn fundamental basic and help can figure out

may be start from kangaroo python script one file easy to modify than C++ code
(sorry I am not coding I am not programmer, just power user know more about computer more end user)

may be my mistake modify code will make kangaroo jump to hit target LOL.

I know kangaroo is code best already. may be change it make it not kangaroo.

just want try to so some possible.

What is kangaroo variable to can modify it like add more value to high?

What is kangaroo power variable on code?

What is tame and wild on kangaroo ?
look like two array and program do compare two value inside right?

Here are what they look like:

Code:

63a169e28af90b75159c93ac88638314 -0000006f7d4a376f241adf3febd1ce73
779155e640a6f97c0d87b47ee5eec0f6 00000bc152a6b02a0bc5730dd5be8ae0

Since these are all 128-bit numbers I'm guessing the left numbers are tame kangaroo positions and the right numbers are distances (with their bit 126 set to 0=TAME constant) right?

This might sound like a dumb question but I also assume the px and py pointers above are the public keys right? No way those can be private keys or kangaroo positions because there are two of these.

These are wild DPs, tames do not use the '-' signs as they are all positive?

Yes, if you looked at a tame file, the left is pubkey x coord and that pubkey's priv key is on the right side. For the wild, the distance is based off of Y coord position, not distance traveled...I do believe that's how it works. Basically, if you took a wild dp and ran the priv key, it wouldn't correlate to the pubkey but the tames do.

Here are examples of mine:

Note: This was posted in the VanitySearch thread by mistake and I later moved it here.

Does anyone here know if the GPU engine makes use of the flags at the end of "distance"? In the ITEM struct there is px,py for X and Y coordinate of a kangaroo and then there's a "d" member 128-bits long that's for the distance.

In the CPU engine the 126'th bit is used as the kangaroo type and the 127'th bit is used as a sign bit.

It in GPU/GPUEngine.cu it doesn't look like the type bit is used at all:

In my (experimental in-development) build of Kangaroo I moved the flags out to an extra parameter so I would like to know if I can safely remove that from here.

OpenCL or Cuda? I am currently using Nvidia Card. As far as I understand, OpenCL looks more advantageous. My goal is to reach the EllipticCurve Point Arithmetic library that works with more than one graphics card. Running Graphics Cards Rig line or Graphics card sharing system such as https://vast.ai
For now, I want to try it on my own computer.

Sounds like you should go with OpenCL then. I think there's an SDK bundled with CUDA toolkit IIRC, but you definitely already have OpenCL drivers provided by NVIDIA installed.

You are better off skimming an OpenCL tutorial first such as https://www.codeproject.com/Articles/92788/Introductory-Tutorial-to-OpenCL without actually writing the example code in there since you don't need them.

I'd probably move out the file saving code from the GPU, you'll only be able to save files from C language on CPU.

Ok. Well the code you are looking at/tweaking is full of GPU code, and the program works with multiple GPUs. That's why I asked. Are you trying to tweak and make your own Kangaroo program or something else??
