I'd rather lose to MARA, which isn't even likely, than lose to the bots, which is guaranteed.

What's your alternative

Send a message to the creator stating that you have solved the puzzle and will convert your private key to SHA-512. Include this message so that if the creator somehow sees it, they will convert their existing private key to SHA-512. If it matches your message, they will send you the reward securely. The reward will remain in His wallet until the creator finds a secure way to transfer it to their own wallet.

Let it go friend, it's one of those people who create fear with a freshly created account that you will probably never hear from again, and they probably have their bots up and running trying to snatch your hard work in seconds.

Upon extensive search, i don't think there's a more reliable way/service to privately mine a transaction than Mara's slipstream, and some member(s?) provably used it to cashout P67&P68 rewards, and the people who didn't use it to cashout P69 and P66 got their transactions replaced and funds stolen sadly.

So as someone before me already said it, i'd rather lose to Mara than some bots.

The Creator ? you talk about God ? because no one can do what you talk about. "externally" of what ?

[NUCLEAR7.1]

This puzzle is very strange. If it's for measuring the world's brute forcing capacity, 161-256 are just a waste (RIPEMD160 entropy is filled by 160, and by all of P2PKH Bitcoin). The puzzle creator could improve the puzzle's utility without bringing in any extra funds from outside - just spend 161-256 across to the unsolved portion 51-160, and roughly treble the puzzle's content density.

If on the other hand there's a pattern to find... well... that's awfully open-ended... can we have a hint or two?

I am the creator.

He described himself as the Creator, meaning the creator of these puzzles.

[Realman121]

Good days to all of you!

You know that sometimes we don't see something very important in our life.
It's like Schrodinger's cat superposition and his G. Simultaneity of existence of the situation.

Sorry, you know that English is not my native language.
Be smart and be dumb.
And this week I start read the one book about abstract of digital signatures. But it's only the one version. And read another. And think about double lambda not only about it of all of it.
And you know that book should read like cat in his superposition or just in two, simply in write direction surely together.
And what I say .. Goodwin the Great and Terrible... yes, of course.
I can say more but - why - it's nothing and at the same time something.
32 BTC prize to who solves it.
As follows higer - that's awfully open-ended.

yes, delete my message or block me. But in that book you indicated and I write here.
Oh, maybe in one day I will be that thief and open this puzzle.
I really tired to find the truth and repair it. And remember all the fairy tale... especially one of it.... of course in two way..
P.S. I'm Blade Devil.....
Have a successful resolution of this case.

 Reconstruction of that message using copilot AI deep think mode

The poster doesnt really believe his own words and is a clown, lets look between the lines and find that
he is essentially saying:

“There is something important hidden in this puzzle that most people overlook, because most
people are not as smart as I am.

It’s like Schrödinger’s cat — two states existing at once — the idea of simultaneity is easy to understand, unlike
reading articles about digital signatures forming alliances with giant kangaroos to step on babies in under 5 seconds
and other such  nonsense.

 I think the solution involves something like a ‘double lambda’ divided by the trace of frobenius divided by the sha256 of
the x y and z coordinates in hex of where the stars will be that comprise the entire zodiac on jan.30, 9002, multiplied by 255.744 + indice of puzzle
 
You should read the puzzle the same way: in two directions at once, or from two perspectives simultaneously.

I’m referencing Goodwin the Great and Terrible (a Wizard of Oz reference), meaning the puzzle-maker appears mysterious or intimidating but the truth might be simpler.

I could say more, but it’s both nothing and something at the same time. Maybe people will think I am the Creator if I sound like a Shaman that became
permafried after one too many "insightful trips" into the meaning of how these keys are made.

There’s a 32 BTC prize for solving it. Motivating, because it will fund my long term venture goal of finding and rebuilding Atlantis.

Maybe one day I’ll be the one who cracks it.

Im destined to crack it. I know this is my destiny.

I’m tired of searching for the truth, but I still remember the fairy tales — especially the ones with dual meanings."

P.S. I’m ‘Blade Devil.’

Good luck solving it, because I couldnt, and I dont want you too either. "


   ANALASYS
This is someone who wants to appear like a mysterious figure with special knowledge,
speaking in metaphor because they don’t know the math well enough to be precise and
resorting to fairy tales  referencing chrödinger’s cat, duality, double lambda, reading two books
at the same time when the orion constellation is aligned with the pyramids at the giza plateau. ..
 Classic “there’s a hidden layer” language from someone who senses structure but since he
can’t fgure it out then diverts it to a mysticism that nobody can figure out, hoping  to appear
enlightened enough to be an enigmatic presence on the forum. Needing attention, living in
a metaphorical, not technical delusion where he thinks he is spreading insightfulness to the
narrow minded masses that comprise the rest of you.
Any actual cryptographic operations are not regarded here in the slightest.
If you are looking to solve these puzzles using references to:
Goodwin the Great and Terrible, Blade Devil, or how he, "The Theif" will be the one bestowing
puzzle keys, well, this is your GO TO guy. For those who want dramatic flair , comparable to the best of
classic 90s WWE skits,  it is highly recommended that you become a disciple of his teachings.


The real message:
“I’ve been obsessing over this puzzle. Ive lost my mind completely and abandonded practical application
chasing a hidden dual meaning or two-layer structure I cant prove at all
I’m reading about digital signatures, elleptic curves, kangaroos, prefixes, hashes, but I’m still confused.
I cant admit this to anyone though. I can never do that.
I want to sound like I have insight, but I don’t have anything concrete. I need to be seen.
I’m tired, but still fascinated. Fuck it. Lets have some fun and see how many dummies
fall for this load of BS. lolz. "

That should about sum it up.

As i see here there are a lot of trolls. The ones who insist going with Mara. Why? Because the company do not care about what is happening inside the pool and the trolls have access inside.
Their own hope is that someone is using Mara, that they win sonething.
Other side of people are the obe who think they are mathemathical smart and nothing else matters...Not everything resume to math....
Also there are another category that comes with ideeas and want some approval from others to see if tgey are on good track but they are stopped from the beginning from smart people that they think they are god
...
So let me be straight: if you think you are smart, why do you stay on this forum to waste time and not be in Hawai or Dubai?

Staying on this forum and answer to all people is not making you smart...

There were some good ideeas but if you stop people trying other methods besides the ones you think this is tge correct path,nobody will discover anything...
Do you think Einstein needed some approval?

Just try your ideea and read more a goid theory, not this comments from anyone here...nobody from here is god, not even the creator...

If i will discover any wallet i will send it to genesis knowing that from there cannot be transfered anywhere...and i were to been a hacker i were transfering all money from wallets to genesis wallet, just to proove that Satoshi is just a project name and not a person.

This is a complete bullshit proposal and advise and you should know better and refrain from posting such nonsense.

Why should the "Bitcoin puzzle transaction" creator pay someone who proves him to have found one of the lower entropy private keys again out of his pockets when the puzzle creator has the same problem to withdraw bounty coins from "snipeable" low entropy key where you have to avoid to broadcast their public key in the public? No problem, if puzzle creator owns Foundry USA or so, sure, or such a significant amount of hashing power that he can mine a block easily on own terms and non-publicly in a reasonable time. How likely is that?

I can't believe such stupid withdrawal procedure proposal is posted here in public. Do yourself a favour and maybe change the drugs you likely consume. Your mental deterioration is quite apparent and alarming.


Is MARA Slipstream still good for puzzle #71 as it was for puzzles #67 and #68? We will see, I don't quite think they've turned to be evil, but I don't work at MARA nor do I know anything internal to them. I am of the opinion that it would be economically stupid and killing Slipstream and their company's reputation if MARA would allow abuse of transactions sent to Slipstream for non-public confirmation.

What I definitely don't like is their current asking for "personal data" to use Slipstream. Sure, you can fake it mostly, but still a pain and not in the spirit of Bitcoin. MARA morons, we watch you!

Because the company do not care about what is happening inside the pool and the trolls have access inside.

Any proof for your claim?

Is today nonsense-day??

You misunderstood my point. I am not suggesting that the creator blindly trust random claims or pay “out of pocket.” I am saying that the creator is ultimately the only party who can realistically coordinate a safe withdrawal method for low-entropy puzzle keys without exposing the solution publicly.

The winner has the same problem as the creator: broadcasting a spend from a vulnerable key can immediately expose the public key and allow sniping. That is exactly why I suggested an off-chain proof approach first.

If the creator can verify possession privately — for example through a deterministic commitment derived from the private key, such as a SHA-512 hash or another agreed cryptographic challenge — then both sides can coordinate a safer redemption strategy before any public spend occurs.

You yourself already acknowledge that private confirmation channels like MARA Slipstream may help reduce sniping risk. My point is simply that the creator likely has more mining relationships, infrastructure access, and coordination ability than the average solver. Previous puzzle withdrawals strongly suggest that.

You can disagree with the proposal technically, but calling it “BS” without addressing the underlying sniping problem does not solve the issue either.

[Cricktor]

...

There's absolutely no need to full-quote me, especially when you directly respond after my post. Apparently nobody cares here of any sane quoting, nothing new.

A Bitcoin transaction can't be confirmed "off-chain". Off-chain solution verification and cryptographic commitments are possible but why should the puzzle creator commit to it? Makes no sense for him in my opinion.

If the creator can verify possession privately — for example through a deterministic commitment derived from the private key, such as a SHA-512 hash or another agreed cryptographic challenge — then both sides can coordinate a safer redemption strategy before any public spend occurs.

I understand that you prefer to have it as easy and safe as possible if you were in the situation to actually find any solution. Maybe that's not part of the challenge? I don't see a reason for the creator to commit to make it easy and safe for a solver. Why should he/they?

My point is simply that the creator likely has more mining relationships, infrastructure access, and coordination ability than the average solver.

That's a claim based on no evidence and just wishful thinking.

Previous puzzle withdrawals strongly suggest that.

I likely don't understand what you mean by this.

I will see for which puzzle withdrawals mempool.space has data if transaction was received in public or there was some other indication of a RBF war with snipers (and being possible to unconditionally use RBF to replace an unconfirmed public transaction). I'm also a bit too lazy now to wade through this thread to dig up the withdrawals of solved puzzles.

Why do many hunters prefer targeting puzzle #71 (range 2^70 to 2^71−1), where only the address is known, instead of puzzle #135 where the public key is already known?
Intuitively, knowing the public key should make the problem easier than having only the address. However, the community still seems to consider #71 far more realistic to attack than #135.
Is the difference simply caused by the enormous gap in keyspace size between 2^71 and 2^135, even though #135 provides the public key?

Nobody has said that puzzle 71 is easier to attack than puzzle 135, or at least I haven't read that from anyone yet. It's possible that 135 is mathematically easier, but there's a factor you're not taking into account, and that's that people like Retiredcoder have a significant advantage with farms, so technically competing against these people is more difficult than competing against those who are looking for number 71 purely by luck.

For brute force, average find time = 50% of range searched, so for 71, that’s 2^70 / 2 = 2^69
For 135 using kangaroo, estimated ops is sqrt of range size. So that’s 2^134 / 2 = 2^67

And speed for kangaroo is faster because it’s not doing as many hashes as brute force. But even if they were the same speed, 2^69 > 2^67.

That is, Brute Force for Puzzle 71 practically requires more operations than Kangaroo for Puzzle 135, according to this estimate.

[NUCLEAR7.1]

I just found this thread now, did somebody crack the puzzle?

Yes, in 2025, a user named Bram won puzzles 67 and 68. as he said, he received funding from investors to cover the cost of renting a GPU. It was a profitable project because the cost was less than the prize, but it was still a huge cost, like $150k to $300k. Puzzle 66 was solved quickly because the key was at the beginning of the range. The person who found it was a stupid, as he broadcast the transaction publicly. The public key was exposed in the mempool, and the reward was stolen because bots hacked the private key using the Kangaroo algorithm to find the private key in a few seconds. They replaced the transaction with a high fee, and he lost $400k. The same thing happened with puzzle 69; it was stolen by someone who didn't know how to broadcast a private transaction using slipstream to avoid exposing the public key. Now, with puzzle 71, it's like searching for a grain of sand on hundreds of planets, but I discovered a dangerous pattern. I analyzed it for 5 months and found the key's location in the 61-64 bit range. The cost of scanning starts from $15k-$30k or more. And the forum has many useless people who claim to be intelligent and who will find the key in 2,131 After 105 years.
