Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
I completely agree — no one has really explored this area deeply. That’s likely because of the overwhelming complexity, which discourages many due to the sheer scale of the mathematical research required. But if someone dares to explore any possibilities or probabilities hidden in this mountainous domain, it should be encouraged — not criticized or dismissed.
Sorry but you are mistaken.
The fact that SHA256 is a non reversible algorithm with no link between inputs and outputs (and with uniform distribution) has not only been proven mathematically, but this proof has stood the test of time for 25 years.
Bitcoin relies on that. So if you think prefixes (inputs) have ANY impact on their sha256 (outputs) it means you break this sha256 proof, which again, has been made by cryptographers 10 leagues above anyone posting in this thread.
EDIT :
A bit of reading if you're interested on SHA256 security against collision attacks. (esp. section 4.3)
https://link.springer.com/content/pdf/10.1007/978-3-540-24654-1_13.pdf
Let’s clarify something I’ve observed from those prefix supporters:
Prefix-based approaches aren’t about breaking SHA-256 or any hashing algorithm—they’re about optimizing search efficiency within a small keyspace.
There’s a big difference between violating a cryptographic function and experimenting with how we structure brute-force attempts over limited key ranges (like 69–71 bits).
Strategies like Kangaroo and BSGS don’t contradict SHA-256 either, yet they’re widely used to reduce computational load. Prefix approaches follow a similar mindset—not to break cryptography, but to shave off time and cycles where possible.
You’re quoting cryptographers “10 leagues above anyone here”,, fair enough. But those same cryptographers also encourage experimentation.
At the end Cryptographic exploration isn’t always about proving someone wrong—it’s also about creatively testing the boundaries of what’s possible within what’s already established.
Also, I appreciate the link. I'm definitely going to read through section 4.3 to understand more about SHA-256’s resistance to collision attacks. Valuable share.
Lol, I came here to calm things down, and somehow ended up being the guy stretching the thread even further!
Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
No one can definitively prove that there's no connection between the prefix and the private key—just like you can't conclusively prove that there is any relation.
So in my opinion, it would be better to pause this debate until either side can bring stronger evidence. Right now, it's just unnecessarily stretching the thread without any productive outcome.

All 3 steps in the algorithm are designed so that there is no connection. It’s part of the basic properties of a hash function and of an elliptic curve. Having a connection means there is a different flaw in all 3. So unless people come up with a proof of each of those flaws, then there is no link. Not the other way around.
Agree on not talking about it anymore, given how something so obvious is hard to understand for some.
Everyone knows about the three irreversible processes involved in address generation from a private key. But what's truly interesting is what @mcdouglasx pointed out:
The prefix theory for searching matches in Bitcoin is a mathematically unexplored topic; it has only been investigated for the purpose of vanity addresses.

Rather than demotivating or distracting someone with endless arguments, it's more constructive to support those who want to dive deeper into new ideas. I respect both of your perspectives, and I’m just suggesting that instead of engaging in debates that might humiliate or discourage others, we focus on fresh approaches. That doesn’t mean every crypto rookie gets a free pass to drop “hot takes” with no homework
this isn’t Twitter, it’s math!Fresh approach For example - Kangaroo & BSGS now Prefix-based strategies seem to be another tool of that nature - not a breakthrough, but possibly a way to refine brute-force efforts when dealing with the small key ranges like 69, 71, 72 Bits & so on..

Hey everyone, If you have a high-core CPU (e.g., 16 cores or more), could you kindly run this script for me and send me back the generated found_seeds.txt file?.. Thanks

Why is this guy hell-bent on attacking @zahid888, even after he apologized—when he didn’t even need to? All he did was ask for a small share in return for using his modified script, But no, the real reason is clear: he’s pissed because Zahid didn’t spoon-feed him code like @nomachine did.
Let’s be honest—if they get something for free, they’re all smiles. But the moment you ask for credit or a share, they flip out and start throwing insults. Pathetic behavior from someone who clearly can’t handle the fact that not everyone works for free.
I disagree and proved it both formally and empirically.
What?? U proved?, lol

I#ve just found that Cyclone wrongly reads the ranges from file and/or changee them.
For example, I have small ranges with an amplitude of 0x1000000 and Cyclone changes the ranges to an amplitude of 0x10000000000
For example, I have small ranges with an amplitude of 0x1000000 and Cyclone changes the ranges to an amplitude of 0x10000000000
- Fixed range parsing in `readRangesFromFile`:
- Normalized hex values to uppercase.
- Removed whitespace from ranges.
- Added hex character validation.
- Resolved discrepancies between file and direct input.

What do you mean by this stride? Is it working here? By default, it makes sense in a sequential search, but does the function still work if we increase it?

**Is He Really Satoshi?**

Those of us who don't have a powerful GPU or only have a CPU can only sit and cry. 
Haha, true! While others hunt Bitcoin, we’re over here hunting tears with our CPUs. Maybe we should start a new coin—Cryp-to-Cry!
Why the hell is Bitcoin going down and down? If Satoshi doesn’t donate some Bitcoin to me, I curse that Bitcoin will touch its all-time low.

The person who wants to get information from you will write you privately. Like they wrote to me. lolEdit:
So you doubt someone, even after you threw fits because someone doubted you lol.
There are several versions out there that get more BK/s than some public version you are using.
I have one, it gets 7.1 BK/s, one of the public pool has one that is equal or better than mine (sign up and run a range, it's easy as that to verify for yourself). So I have no doubts there are faster versions out there, including Bram's.

The people messaging you privately are just noobs who got their hands on a 68-bit key and thought they were onto something—until reality hit. They quickly realized the number was too large to brute-force, got frustrated, and then stumbled upon a post mentioning some so-called prefixes in the same bit range. That gave them false hope—hope that, in reality, is nothing.
Here’s what they don’t understand (and neither do you): Generating a compressed Bitcoin address from a private key is no joke. The process involves several irreversible cryptographic transformations—first, the private key is multiplied by the secp256k1 elliptic curve generator point to derive the public key. Then, the public key undergoes SHA-256 hashing, followed by RIPEMD-160, reducing it to a 160-bit identifier. Finally, a checksum is added, and it’s encoded into Base58 to produce the final Bitcoin address.
Now, let’s talk about breaking this. Reversing even one step of this process is computationally infeasible. That’s why trying to manipulate prefixes or chase random bit patterns won’t get anyone closer to solving the riddle. The difficulty isn’t just about the 68-bit key size, it’s the entire cryptographic structure that makes it practically impossible.
So, instead of spreading baseless theories, bring some actual proof or mathematical reasoning before making claims.

Alright, guys, stop barking like a pack of clueless dogs.
Just toss this mutt their bones in private since all that matters here is the direct private key of puzzles — no assumptions, no probabilities, no so-called ‘useless’ ideas.
According to this '0.01% self-proclaimed genius,' the '99.99% of this thread' is just pointless noise. The only real minds here, in someone's grand wisdom, are themselves and the Poor solvers of puzzles, who apparently show up just to read articles about Example: 'marapool.' LOL.
So, don’t waste someone's precious time—just hand the dog exactly what they want and let them wag their tail in peace.
**Note:** Next time, only post private keys of puzzles, so the starving dogs can easily grab their bones and stop whining.

It took 67 days.
Custom software written from scratch
Custom software written from scratch
So the full random method? Which solves puzzle 67 in 67 days?
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.
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.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.

That's what I did, I created a lock with rbf completely disabled and it's not pocibel boot or anything superimposed I said that and everyone here laughed in my face and told me to prove it.. why prove it if I already knew.. lol
Holy cheese and grits and gravy. How many tests have to be ran before people finally get it that disabling RBF is not fool proof?!?! Public tests have been ran a few times, to show that even with RBF off/disabled, a tx can still be changed, diverted to another address.
hotmoney ate up how much forum real estate to say something totally false:

Non-RBF transactions cannot be modified or replaced.
Geesh.
It seems that the solvers do not disclose the paths they followed, especially for searching addresses without exposed public keys, thus the "Large Bitcoin Collider" does not maintain its course. Nowadays, we only see developers omitting to share their information, as the current era is all about criticizing everything, being rude, and unproductive. Each time, the end draws closer, the day when this post will be buried forever. However, I keep hope in those closed circles, where the few members have a respectful approach to sharing ideas.
The last solver did explain how it was all done.@wondring_philosopher, did you at least get a donation for inventing the Marapool method, or are we just handing out free genius points these days?
And seriously, why are people still stuck on RBF like it’s some unsolved mystery? Enable it, disable it—makes zero difference. The last puzzle transaction went through just fine with RBF on, and the funds got swept without a hitch. So, can we please move on? No need for another AI-generated essay to ‘educate’ us—it’s already clearer than a blockchain explorer on a sunny day.

He was talking about the 66th puzzle. after it was solved.
Okay, my bad. I thought he was talking about predicting the next puzzle, but he was actually referring to Puzzle 66 with some BS. However, I still have my doubts that retired_coder and satoshi_rising are the same person. This thread spans 369 pages filled with debates, groundbreaking ideas, successes, and failures. It holds a wealth of knowledge—some theories dismissed, others leading to real breakthroughs. Many thanks to those who contributed to this field by developing BitCrack, VanitySearch, keyhunt CUDA, JLP Kangaroo, Sota Kangaroo, Rotor CUDA, wifcudasolver, and many more.
Now, with all this information, it’s time to build something new.
During my reading of more threads, I came across another person's idea that seems very close to the actual method used for creating these puzzles. Here is the post:
https://bitcointalk.org/index.php?topic=4453897.msg61848712#msg61848712
In Python, it's quite straightforward to implement multiple derivation methods for private keys that are masked with leading zeros. I'm curious—has anyone developed a CUDA version of these methods? If so, could you share a reference link?
Thanks in advance...
