[albert0bsd]

I saved #115 on  0ctober 3rd the private key and timestamp and I never did find any other source before that, I may be wrong can I find the official record?

#115 ( 1NLbHuJebVwUZ1XqDjsAyfTRUPwDQbemfv ) Solved 16/06/2020: Priv=0x60F4D11574F5DEEE49961D9609AC6

You can find the timestamp directly in the blockchain

this thread makes me want to drink heavily and hurts my head because of this pattern:

[rando new person]: I did it! I figured it out! <Insert not-plausible solution here>

[person with established account and actual contributions towards the puzzle]: dude, that's not how math works.

At any rate, congrats to whomever solved 64 this fall.   
I was looking for roto-cuda and found a couple repos with forks of it: https://github.com/search?q=rotor-cuda

I know linking to how to search github is essentially a lmgtfy move but some of youz guyz seemed to need that level of help.

Also ran into this, which looks to be at least a spiritual cousin if not a direct descendant to roto-cuda: https://github.com/graffitilogic/KeyScanner

This person's code looks to be informal with plenty of commented out paths of experimentation but I appreciated that it actually compiled for me in visual studio with minimum effort.
The random number generator was... novel? but the majority of the rest looks to be forked riffs on VanitySearch and BitCrack in the older commits.

anywho happy hunting you crazy kids.

Yeah, seems like it could be a cool project/spiritual cousin however, I am not sure I trust the math/numbers that his program is showing lol

Hello!
...
I found saved kangaroo progress files that allowed me to find key 115 in the past!
...
So for interested groups/individuals - I have these progress files and I will sell them for 2ETH (upfront payment). If you are interested, please contact me via private message. To be fair - I sell files only once.

Regards

Just distribute these files for free and clean your disk space. No need to sale

ha - great eye - yeah, the total completed and hashrate do not jive with the time completed.

it will be 2023 in a few days and progress bars, time remaining and items complete (simple division) remain of the bane of meaningful UI feedback.  Funny, though the version I built didn't seem to have a fairytale hash rate but it also didn't have what I was looking for in terms of gpu-accelerated random-private key production. The key assembly is still CPU bound from vectors of gpu-built device_vector of 16 or 32 bit-length unsigned ints.  Mildy sympathetic.. I haven't figured out a pure GPU method of initial key production, either.

Right!
Yeah, I played with it a year or so ago and the GPU is not ideal. Python is the purest form of generating 1 random at a time (that I have played with and used, maybe something in C would work faster, maybe albert0bsd could create something), versus generating random starting keys and checking x amount from the starting key until it's rekeyed. Even the CPU with these programs doesn't create a random key and check and a new random key and check...the CPU still creates random starting keys, etc.

My VBC can solve a 36 bit pretty fast in random mode, but that is a small space compared to 66 bit and beyond. Soooo for now, I am checking each and every key, spread out over the entire key space. 30 quadrillion keys and counting lol...

Hi nerds 🤣 I have a question, I just started to code this morning, could anyone give me advice and tell me what I am doing wrong here? Thank you.

Code:

import ecdsa
import hashlib
import re

# Hexadecimal string range to use as input
start_hex_string = "0000000000000000000000000000000000000000000000020000000000000000"
end_hex_string = "000000000000000000000000000000000000000000000003ffffffffffffffff" 

# Convert hexadecimal strings to integers
start_int = int(start_hex_string, 16)
end_int = int(end_hex_string, 16) 

# Target public key to find a match for
target_public_key = "13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so"

# Iterate through the range of integers
for i in range(start_int, end_int+1):
  # Convert integer to hexadecimal string
  hex_string = hex(i)[2:]
  # Check if the string contains only hexadecimal characters
  if re.match(r'^[0-9a-fA-F]+$', hex_string):
    # Convert hexadecimal string to bytes
    hex_bytes = bytes.fromhex( '200000000000000000000000000000000000000000000003ffffffffffffffff')
  else:
    print("Invalid hexadecimal string")
    continue
  # Use SHA256 hash function to generate a private key from the bytes
  private_key = hashlib.sha256(hex_bytes).digest()
  # Use the ECDSA algorithm to create a public key from the private key
  sk = ecdsa.SigningKey.from_string(private_key, curve=ecdsa.SECP256k1)
  vk = sk.get_verifying_key()
  # Encode the public key as a hexadecimal string
  public_key = vk.to_string().hex()
  # Compare the generated public key with the target public key
  if public_key == target_public_key:
    print("Match found! Private key:", private_key.hex())
    # Save the private key here (e.g. write it to a file)
    break

  else:
    print("No match found")

Hi nerds 🤣

That isn't a kind start, is it? Don't be YouTube. 

I just started to code this morning, could anyone give me advice and tell me what I am doing wrong here?

Did you code all that or did you... you know just grabbed it from some git something. If you coded, then asking for help isn't the right place (and maybe no place is right other than your desk). If someone else did, could you provide a link? There has to be a brief explanation of this script.

Code:

# Target public key to find a match for
target_public_key = "13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so"

That doesn't seem right. That variable must expect a public key, not an address.

Oh hello there beauty, I didn't code it, AI did, I'm trying to understand the backbone of private key generation.

This AI I'm asking to code for me is driving me crazy, it writes half completed codes mostly.
OpenAI

Hi nerds 🤣 I have a question, I just started to code this morning, could anyone give me advice and tell me what I am doing wrong here? Thank you.

You're trying to program a robot to solve something that humans haven't solved first.

Also, the output from OpenAI Codex is very inaccurate, and is wrong about 50% of the time for specialized functions. ChatGPT is much better but it can still introduce "variable not declared" errors.

Actually I'm using chatGPT, it is playing dumb when it comes to bitcoin pkey security, well I just wanted to play around with it and try some ideas, thanks for indulging me.

[BlackHatCoiner]

Lol. Why don't you ask it what's wrong then? 

This AI I'm asking to code for me is driving me crazy, it writes half completed codes mostly.

If you don't know how to code, then using an AI isn't recommended (yet). At the moment, it can greatly assist you learn programming, but it can't write exactly what you tell it to do; part of the problem, in this case, is that you don't know either what you want to do. Let alone the AI.

I guess my problem is with math and cryptography, also I'd mistakenly changed the target public address with public key, lol. But at the end I was able to generate keys, not the ones I intended though. To be honest for someone trying to dive into py or complicated coding I managed to learn a lot about coding, which is that I know zero about coding, I had a few classes for web designing, after the third class I dropped out, firstly because I couldn't sit long due to discectomy surgery I had, secondly I found out I wasn't that much interested to learn web design using html, css, java.

But I always wanted to learn how to code something to do exactly what I'd intended, who knows maybe this topic about the puzzle sparked a desire and fueled a long lost motivation to start doing what I really love to do, that's why I'm here after all, to learn from the best.

[james5000]

Hello everyone, I've been studying this challenge for some time and developing some algorithms.

Soon I will post about some curiosities and some numbers

[BlackHatCoiner]

Don't try to reinvent something you don't understand. Use already written code, which is tested.

I'm not a beginner in coding anymore, but I'm sure that the AI can help you a lot. Just ask it whatever you feel lazy about, and you'll see what I mean. Debugging? Explaining? Suggesting? Everything. You only need to connect the dots properly.

This has the same build dependencies as bitcrack, thanks though, guess I'll have to download 40GB of VS and CUDA.🥱

Apologies, I am an amateur coder really so my knowledge is limited. It just seemed similar to your wants.

[WanderingPhilospher]

A new VanBitCracken Random version will be released soon. I am doing some final testing.

The new version works with full addresses with RTX 30xx cards.

It also supports the usual -topr and -subr flags AND now will support -bits. So if you want to dig deeper into the bits range, you can use the -topr and -subr flags, or if you want to randomly search the entire bit range, you can use the -bits flag.

I have CPU and GPU tests in the link below.
