It's hard to believe that Puzzle 67 was opened by simple enthusiasts and not by the creators themselves, since the pool was often attacked by DDOS and 6,69% of the range was already passed, and since the creators of the puzzles know the private key, they can easily monitor how close the pool participants got, so they could easily take their coins themselves under the guise of someone finding them, so this is most likely a scam than some kind of honest competition. Who wants to give strangers more than half a million dollars, it's unrealistic! Let's think about it. Does anyone doubt that this is how things are or do you think everything is honest?

It was open by me, and I'm not the creator of the puzzle.
Let's put those conspiracy theories to rest.

@Bram24732  Are you truely the finder of #67 , if so may I ask how long did it take to search and what app did you use to search?

I signed several messages on this forum which proves it.

It took 67 days.

I think the same as you because no one would give away nearly 1000 btc without getting any profit

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

That's who will own the keys up to 70+!!! How much does it cost for electricity, if it's not a secret?

Full random yes.
I don't wan't to be disrespectful to anyone, but most of the theories I see here about patterns look crazy to me.
The ONLY way I could see a pattern between puzzles is if the creator messed up the randomess (unsecure RNG, predictable seed choice, etc...) and I really don't think he would make such a mistake.

Did you have plan to give a tip for @Wandering philosoper? He the guy research and publish how to avoid bots with maraslipstream.. I hope you did it.

[dariusdecryptor]

Let me see if I understand this far. This puzzle is almost 10 years old and no one has solved it yet? Ah, I'm going to dedicate myself, I'm going to fry my brains out, but I'm going to solve this puzzle, I not only want, but I really need these 32 bitcoins

[kTimesG]

Several thousand

Can't see how one would have made profit out of that. Was it just for kicks, RetiredCoder style? Throw away hundreds of thousands on a problem without caring much if it all gets lost or not...

Or maybe I don't know where to look to get my hands on several thousand RTX 4090 that cost something like 5 cents an hour.

An optimized CUDA kernel that targets some specific hash can do well above 7 Gkeys/s on a 4090, I guess that means only around 1000 GPUs would have been required.

Bold of you to assume the puzzle hasn’t already solved us in the process. 

[Desyationer]

I have only ~ 3Gkeys on Vanbitcracken + 4090, how 7?
Bitcrack is very old and i have only ~500-600 mkeys

Huge respect for WP, I think his tutorial is great for education purposes.
But a tip for a tutorial on how to sign a tx offline and paste it on a webpage is a little too much to ask Especially since I didn't even see it until a couple days ago.

Not only for this tutorial on how to sign a tx offline, but his effort and his willing to share his experiment to this community. I believe no one here hear about this method until @Wandering research all way until found best method to prevent reward stealth by bots.. I think he don't want tips too, but everyone who give big contribution to this communities should get appreciate for their contribution. Any way is back to you is just my opinion. cheers

Do whatever you want—it’s your money. But let’s not downplay a groundbreaking invention by calling it ‘just a tutorial.’ It has re-energized many of us. If I were in your place, I’d definitely remember him in my success, even if it was just a small token of appreciation. Anyway, best of luck with Puzzle 68! Now that you have both money and resources, the rich get richer while the poor stay poor. We’re just here as the audience, stuck in watch-only mode.

I don't think anyone had heard of the MARA service if @wp hadn't discovered it. I believe you're undervaluing their valuable contribution. It's important to highlight and give credit to those who deserve it, as their contribution opened new perspectives and solutions.

Guys, stop trying to pressure the solver into doing anything. If you're nice, maybe he will stay and you can learn something from him.
We are all grateful for WP's post, sharing a method to securely withdraw a puzzle prize. Nobody is obligated to tip anyone just because you used MARA. You can always show your appreciation for what you've learned by directly sending a tip yourself.

Over the past few months, despite multiple tests of the reliability of MARA's service being successful in safely transferring funds from one wallet to another, people repeatedly continued to cast doubt about MARA. Everything from them having "rogue" employees to hackers having SSH backdoor access to MARA. That was all just a bunch of nonsense. MARA is a publicly traded US company, listed on the NASDAQ stock exchange, with a real board of directors, accountable to their shareholders and clients, and probably with US regulators breathing down their necks, making sure they comply with demands from the SEC, IRS, OFAC, and various law enforcement agencies. There has not been a single instance of a transaction submitted to MARA's Slipstream service being compromised in any way. So give them some credit.

Not too long ago, I used MARA to send my own bitcoin to perhaps the most compromised wallet in the universe (hex private key 0000000000000000000000000000000000000000000000000000000000000001, WIF: KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU73sVHnoWn, compressed address 1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH) and then successfully sent it back to myself. I even enabled RBF for both transactions. Any bitcoin that is normally sent to this address gets instantly snatched up by bots. If MARA was compromised in any way, bots would have stolen my coins. But that didn't happen.

It is not about a donation; that is up to each person if they feel like donating or not. It is more about valuing the contributions and not undermining them. He talks as if it were a 100% original milestone. It is obvious that his solution is just a method already exposed here, and its only advantage was great computing power. So, unless it is something else, the answer is simple: he has nothing to teach us that we do not already know. From what he says, random method with thousands of GPUs are things we already know. I suppose the most he could have added to the software is a database that records already scanned sectors to skip them later.

Did you read his methodology? It wasn't only random scanning and lots of GPU's.

The method was:

Break up puzzle 67's keyspace into 256 sub-ranges each with 2^58 keys
In each sub range, save every private key that generates an address starting with 48 zero's
Statistically there are 1024 proofs in each subrange
If an average of 1024 proofs are found in a sub-range, it statistically guarantees the whole sub-range has been scanned

What software are you talking about? He used custom software. I'm sure he'd like to keep his competitive advantage to himself.

It was found after scanning 57% of the keyspace in 67 days. Which works out to over 7 trillion keys per second. Which, my napkin math says is around 1600 x RTX4090's.

Several thousand

Pretty close. Would need more than 1600 GPU's if they were not all RTX-4090s.

And right now, ~4 days and 2 hours since puzzle 67 was solved, assuming the same scanning speed, he's already scanned almost 2% of puzzle 68.
