Bitcoin puzzle transaction ~32 BTC prize to who solves it

I did.
Now, where's data to backup your stolen credit cards claim please ?

Can you show me the signature tx I made?

I said it as an assumption about the credit card. Because there is no logic in giving 5 liras and getting 5 liras. You are the one who stated this on Twitter as "WE GOT RICH". It is not a logical behavior.

[Bram24732]

where the return is not substantial and risky.

This is wrong.

one could focus on ranges 135-140 with the same expenses.

This is also wrong.

I sent 15 messages on this forum, two are signed.
If you can't use a forum search to find a message within 15 posts, you really shouldn't try to find a private key in a 2^66 space.

You did not sound like you were making an assumption, but I'm glad we could sort this out.

Says who? You're now an expert on the ECDLP solving as well?

I highly disagree. I believe you are not aware that the computational costs for solving ECDLP are around 2x lower than cracking a hash via brute-force. And this when using highly optimized CUDA-based software, in both cases.

If this is hard to understand, another way to put it is that a CUDA software that solves ECDLP handles 2x more public keys / second, than the amount of hashed public keys / second.

Considering that the 135 value is 2x higher, you could have easily used those thousands of GPUs (or whatever their number was, what matters is the amount of computing you threw at the problem), to get a reward 2x larger. Which means, a higher profit, magnitudes larger considering your spendings.

I don't know if i'd consider myself an expert on the ECDLP. I think know a fair bit about it.
And yes I'm aware of what you're telling me. The 2x is not that clean cut though - Or maybe my code sucks, I don't know.

The choice for 67 takes into account the ecosystem. There was little to no competition on those puzzles (all pools publish their numbers) while RC is probably working on 135, and I can't know his progress. A lot can happen in a year.
The profitability depends on the odds that someone else breaks the key before us, and taking that into account focusing on 67 was the better play.
I did not pick the target out of a hat. I modeled the odds and profitability, and chose accordingly. Had the risk/reward been better on 135 I would have started there.

Oh, that was a reply - from someone not even in the group haha, I remember now

The one who isn't even in the group? The one who made the first post and the one that ProofOfDuck shared the post with.

Now you've left me wondering. Is it really you?

People may know each other and not participate in every endeavour you know.

[mcdouglasx]

? Can you give a link to the program and .BAT file with the correct command line for puzzle 68

The code is not in the cloud, it is not a .bat file, I just modified Keyhunt for testing. Anyway, the idea is already out there; anyone could replicate it in an optimal environment with CUDA.

It's basically useless. McDouglasx is just an enlightenment teacher. You can find the link you want from his homepage.

Yes, whatever you say, you have the right to believe and think whatever you want. I don't understand the hatred some people have for criticizing everything and never contributing anything.

It seems they lead an unhappy life and this forum is some kind of outlet. Well, if that makes you feel good, go ahead, it doesn't affect me.

[WanderingPhilospher]

Why is every one saying or assuming that 67 was not profitable??

With a slower cracking tool, keys/s wise, and at public rental costs, one could have solved 67 in 67 days, burning up $369k. Bitcoin price fluctuates, but when Bram entered the competition, it was hoovering up or below $100k; so the prize would have been valued at $670k. $670k - $369k in 67 days is one helluva ROI, I don't care who you are.

Now, this is not taking into consideration that Bram had a faster Keys/s program nor that he could have lined up agreements with GPU farms, which is not hard to believe or understand.

If I rent my rigs on Vast; I make .20 cents an hour. Of that, Vast takes almost 35-40%. So why wouldn't I rent to a private person for .15 - .16 cents an hour, and make more than I do via Vast? Or I could be mining some alt coin with my GPUs and get approached to lease them for guaranteed, paid up front, $. If the amount being offered is close to or more than what I make mining, why wouldn't I?

So if he had a faster program and negotiated lower rental fees, his profit would be even more.

@zahid888

I dont understand how you get your seeds are you just randomizing them? I update your code for multiple GPUs:

Code:

import random
import subprocess

while True:
    x = input('seed integer : ')
    seed_value = int(x)
    random.seed(seed_value)
    seed = str(seed_value)
    a = random.randrange(2**31, 2**32)
    random_start = "%00x" % a
    random_range = (random_start+"000000000:"+random_start+"fffffffff")
    print('\nSeed : ' + str(x) + ' KHex : ' + str(random_start) + '\n')
    cmd_command =('VanitySearch-1.15.4_bitcrack_th512gr -stop -t 0 -gpu -gpuId 0,1,2,3,4,5,6,7 --keyspace '+random_range+' 1MVDYgVaSN6iKKEsbzRUAYFrYJadLYZvvZ\n')
    subprocess.call(cmd_command, shell=True)

Decrease the 'a' and increase zeros`: According to your speed..

@Wandring_philosopher..  please tell me if you have tried anything more about the stride or if you plan to do so?

Why is every one saying or assuming that 67 was not profitable??

The solver's answer says so

I see, one more question how many GPUs did you use to find it?

Several thousand

Calculate several thousand GPUs by 67 days paid rental,

the only other option he hinted is that it was found by a pool, then I will believe it was profitable.

Well from his previous posts you can clearly find out that he is running some kind of seed recovery business - so most likely he owns all his cards, or have some other (cheap or free) sources 

[mcdouglasx]

Those who do not see this search by @Bram24732 as profitable are simply biased, due to the mathematical errors propagated here. They are the ones who believe that an entire range needs to be scanned, which I find absurd, especially when we have the kangaroo method as proof that statistics and probabilities can be used effectively to find solutions without scanning entire ranges and are the best path to follow. I hope this serves as an example and they stop believing in "AI prompters".

I repeat for the thousandth time: probabilities are counterintuitive and challenge logic.

We got it, chief. No need to repeat yourself 1001 times though. It sounds like you are trying really hard to convince us about something, maybe invest this precious time into writing a paper about it instead of fighting with our AI-based empty brains. I know, we are all ignorant idiots, living unhappy lives, so we definitely need AI to be able to fight anonymous people on the internetz. Personally I tried bringing you back down on planet Earth by providing you with actual counter-proofs (practical ones, not BS theory) and everything you wanted as an argument, but I failed miserably, because, well, "no contributions" and etc. You are correct, probabilities are counterintuitive, but that doesn't mean you can't be wrong, it's just that maybe it's impossible for you to see it clearly. Not sure why you would hope for any of us fools to see the correct wavelength of the day light, as you do.

I will now need to go ask AI about how is it that kangaroo or bsgs doesn't need to scan an entire range, but matching a hash does, seems counterintuitive. Oh wait...

Hello. Can anybody explain to me please, how this 67 solver guy proof that he is actually a solver? Thanks.

First of all, why do you always speak on behalf of everyone? Are you some kind of boss here? You remind me of Digaran; a piece of advice, be careful with that path, he ended up ignored and expelled. You never give anyone credit; you always talk about theories and tests that only seem valid in your mind. At least I don't sell smoke: I publish codes that may seem useful to you or not, but at least they work in practice. Maybe not for what you need, but they work and are available to everyone, at least in my case. While you may be right about some things, there are many in which you are not. I don't know how old you are, but you must understand that we are not always going to agree with you, and everyone can make mistakes. Every so often, you contradict Retiredcoder when it is evident that his method is the best to date; you say you have a hyper-fast method (still waiting for it). You minimized KeyHunt and undervalued BSGS, which is part of our lore. Now Bram resolves probabilistically, and you have something to say. You give condescending responses here and there. Ninety-nine percent of your comments are mocking attacks. In the end, do you think that way of acting is correct? You don't know how happy it would make me to see your promising version of Kangaroo and give you credit, to show you that it's okay to do so. But I can't give you credit on things if I don't think you deserve it.

Hi @zahid888. I am curious about this from last year.. I even write some python script to try to understand this, but still didnt get that :

It’s just a few lines of code, bro—why overcomplicate it?  Remember, it’s only for generating the starting point!

Below is full demonstration & Code

Demo:

https://www.talkimg.com/images/2025/02/25/q4fzj.gif

Code:

import random
import subprocess

print('''\n\n      Demo By Zahid888\n

    seed_value = int(x)
    random.seed(seed_value)

    random_start = "%00x" % a
    random_range = (random_start+"000000000:"+random_start+"fffffffff")
    print('\nSeed : ' + str(x) + ' KHex : ' + str(random_start) + '\n')
    cmd_command =('BitCrack.exe -b 128 -t 256 -p 512 --keyspace '+random_range+' 1BY8GQbnueYofwSuFAT3USAhGjPrkxDdW9\n')
    subprocess.call(cmd_command, shell=True)

If you do the calculation, puzzle 67 solver only realized a lot of losses,
67 days x 24 hours x several thousand GPUs = more than puzzle 67 price. I think that's why he is not giving any donations right now.

There’s a big difference between someone posting a youtube tutorial in 2005 and someone introducing an idea at the right time and right place, @Wondrig philosopher didn’t just share information—he brought forward a solution when it was needed the most.

Innovations aren't always about inventing something entirely new; sometimes, they’re about applying knowledge when it is truly needed.

Anyway...

Hi @zahid888. I am curious about this from last year.. I even write some python script to try to understand this, but still didnt get that :

Hey Bro, welcome to the black hole! Just a friendly reminder—if you win, I definitely expect an appreciation fee... Fair trade, right?

Have you heard of render farms ? I think they can offer their "services" for custom cuda software - and often have thousands of GPUs and much cheaper than standard cloud gpu instances.

One of the many theories 

What you wrote is not theory, it's reality
If you want to rent 1000s of graphics cards, you will need to use Render farms.
