[ARCHIVE] Bitcoin challenge discusion

[BiThemis]

You can also use Pollard's kangaroo algorithm in a new puzzle where for one private key found you get one BTC coin.
Reward: 1 PRIVKEY = 1 BTC // of 144,000,000 PUBKEY
Search for private keys from a large list of compressed public keys.
The number is: 144 million public keys.
The most effective private key search tool is the Pollard's kangaroo algorithm.

Please be careful with this. As bounty0z already said, this is hidden scam. The details I described in his main topic:
https://bitcointalk.org/index.php?topic=5209950.msg53360293#msg53360293

MrFreeDragon can you prove that this is a scam?

MrFreeDragon can you prove that this is a scam?

BiThemis, I made the answer with the arguments in his main topic. The answer is logic and written in step by step way.
No reason to pay 1BTC for the 0 balance address. Also there is no the source address details as well as the signed message by that address (because the source address is the target address known only by the author).

What you wrote is not proof. This is your opinion and assumption.

I like your way. You asked me why, I answered with the arguments. If you have another opinion, you are welcome to share it here.
If you are ready to find private key to one of that 144million pubkeys, you are also can do it. I just told to be careful in this, and explained that it is a hidden scam.

I have another opinion and assumption that you are (BiThemis) and the auhor of that project (Secp256k1PRO) is the same person just with different user names here. But of course this is only assumption. Why? It is strange that you have only 2 posts, both these posts were made today with the questions to me. You are like the advocate of that hidden scam project.

Please also be polite, and if you want to discuss something - discuss. But not just say "this is not proof", and "this is your opinion". I know that it is my opinion, thank you  You said nothing new to me.

[BiThemis]

I wish I had the ability to solve it. It's a very exciting competition. But not everyone is a software developer. Blockchain presents a new world. I'm late to learn software. I want to start again with a thrill. A small draw would be easier for me: d

For the "Secp256k1 PRO" project, CUDA software is suitable. I know that Russian guys have Pollard-kangaroo-GPU.

[vimp666]

2.5 gigabytes of public keys. Before starting the search, need to know how many bits are in the key. Or did the author collect all known public keys with a balance or invented them myself?And the keys are most likely changed. If you find a private key with 500 bitcoins, why do you share with someone? kangaroo work with only one key. And in what space look for a key? 0-256 bits?no one gpu kangaroo can no scan all 256 bits.scam.

[Ambirus]

kangaroo work with only one key.

You can run on a large list of public keys.

1.And so Telariust answered>>>>>
Simultaneous pubkeys calculation will overly complicate the program.
And important: for N keys, performance will drop N times.
Sry, but i dont do it.<<<<
2.With this list of keys, the speed of the kangaroo will drop by 99,9%. I think so.
3.Let's hypothetically imagine that you found 1 key and received 1 bitcoin (and the address was 150 bitcoins. For an example). And the creator of this entire list took the remaining 149 bitcoins.
4.You don’t know the key space. Do you want to check the entire 256-bit range? You will not have enough remaining time until the end of the universe.

[Hurtson]

Hello, Why Not possible to use Pollard Kangaroo for CPU/GPU in Random mode? I think It would be More effective While searching wallet from More than 100 Bits isn't??

or can i use it for specific ranges?if yes, give me a link please or post command with ranges.

Version 1.3 of the ttdclient has been released in both windows and linux versions.  The big change for this version is an updated settings.ini file that allows your client to compute between 1 and 16 ranges.  Lets say you have a 2080 ti that can do 1280 mk/s according to bitcrack but because of startup time your only getting 1020 mk/s according to ttdclient.  If you set ranges to 8 you essentially reduce the time wasted on startup by 87.5%.  As always I am available for assistance if you need any.

I also have 4 amd 290x gpus for sale for $50 each or $150 for all four.

That's just awesome, will get the latest version up and running when im home from work

Thanks for your continued support of the ttdclient pool

https://2coin.org/getRSZfromRawTX.html
Python alternative: RawTX_RSZ.py
get R. S. Z. value python2.7
https://github.com/160Bit/Bitcoin-Key-Compression-Tool

When I start a file R-Scaner.py

C:\Python27 > python.exe R-Scaner.py
SCAN ADDR
type address: - here I write the address, which I want I check

Also I receive result of check.

When I start a file C:\Python27 python.exe RawTX_RSZ.py
I receive such result:

Traceback (most recent call last):
  File "RawTX_RSZ.py", line 1, in <module>
    import bitcoin
ImportError: No module named bitcoin

I thought, that will be written:

SCAN TX
type tx: - here again it will be necessary to write transaction, which needs to be checked up

What I do not correctly?

What for in a file RawTX_RSZ.py this is written down transaction? 

tx =
"01000000013c10dccdd96187ec065a2404a829be91ccb2a80ee7986d4cbbb31cd493f69e5d00000 0006c493046022100c9f051042467433b2199526db1ba327154d2bcd7c90c40070ba06869c55121 94022100b1146f90fac7ed0db71d2f0c91f30c51d11310c508a64719dc424cdf710cb38b0121025 45d2c25b98ec8827f2d9bee22b7a9fb98091b2008bc45b3b806d44624dc038cffffffff0200c501 5a020000001976a914f507b67f6af2dcc993f6958c05855f4861cefe8888acc427e9254f0600001 976a914b3dd79fb3460c7b0d0bbb8d2ed93436b88b6d89c88ac00000000"

I can not find the instruction, as correctly to work with a file RawTX_RSZ.py

[iparktur]

Code:

install ubuntu 18.04 LTS or windows 10 app

install python 2.7 + package

sudo apt install python
sudo apt install python-pip
pip install bitcoin
pip install ecdsa
pip install utils
pip install base58

git clone https://github.com/160Bit/Bitcoin-Key-Compression-Tool.git
cd Bitcoin-Key-Compression-Tool
python RawTX_RSZ.py

good luck! +

you will make a video about it soon-)

If   WIN-7- 64   - allowed ?

Let me know when the video is ready, please ...

Now RawTX_RSZ.py works

It turns out, that for decoding everyone new transaction needs to open and to edit a file RawTX_RSZ.py - to write down in him(it) new transaction  .

Whether and it is possible to make, so that at start of a file RawTX_RSZ.py the field opened
SCAN TX
type tx: - here again it will be necessary to write transaction, which needs to be checked up

OR

So, that the file RawTX_RSZ.py read from a text file, for example RawTX_RSZ.txt in which previously is written down
next transaction, and result it is possible to deduce(remove) in a window PYTHON or to save in a file (for example) RSZ_RES.txt

Your questions are off topic!

Thanks - I shall try.

Yes I understand, that my questions have deviated this theme.

I APOLOGIZE...

If are available on this forum of a branch on themes of use in PYTHON of such tools as

RawTX_RSZ
Recoveri_wallet
R-Scaner
r-s-z-to-wif

And others, on similar subjects - prompt section, or link

I tried to search, but has not found

Hi   gunchefi  !

I was able to change a little.
You can send PM me  -  I will say to you what I did.
