Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it

what is the most basic puzzle i can start with?

You can start with 71, but please be aware that ALL PUZZLES UNTIL ABOUT 86-87 SHOULD BE WITHDRAWN WITHOUT USING PUBLIC BTC MEMPOOL. USE SLIPSTREAM SERVICE OF MARA POOL TO WITHDRAW SUCCESSFULLY.

And what's the plan for your $100 challenge? Gonna play it with MaraPool's slipstream, or rolling the dice with a regular mempool transaction?

And this is not so powerful CPU Ryzen 7 5800H

I recently forked your Cyclone and added a couple of tweaks Now with -bit and -subzeros for Fine-Grained Private Key Range Control.

-bit – lets you select the bit length for the random private key range (e.g. -bit 71)
-subzeros – lets you define how many trailing hex characters (zeroes) the range should have.

Code:
-bit 71 -subzeros 8

This will generate a key range like:

Code:
4ec00159ac00000000 : 4ec00159acffffffff



You can adjust the number of zeroes based on your CPU thread count and brute-force capability.

I’m planning to build or buy a more powerful CPU setup (under $2k), and I’d love some suggestions from the community on CPUs with strong multi-core performance suitable for this kind of workload.

Any recommendations are appreciated!

the key was found after 0.7206% of the range.

So someone solved puzzle 69 using a modified Cyclone in 20 days?  Huh
Hi all! Modified version with jumps and partial match: https://github.com/Dookoo2/Cyclone
Try your luck:)

With a small tweak 😉. I'm still a bit confused about how the jump function works, so I avoided using it. Interestingly, it seems to take the same amount of time with or without it.

It’s hard to believe people are still making such mistakes. I honestly feel terrible for that guy.  Angry

For all the prefix people, I found these.

Hahaha, take it easy... It’s not that simple... But... Every member in this topic will get 0.2 BTC—if they have a BTC address in their signature. Satisfied?  Grin

Are you talking about that key?

Code:
KyDi5tDzUCEN5bCRZhiS5sEGMpmcRZdpAhmWLRfMmutGmPHtjVob
KyDi5tFNbmN45bCRZhiS5sEGMpmcRZdpAhmWLRfMmutGmPHtjVob

L3DiBgEqot9K5bCRZhiS5sEGMpmcRZdpAhmWLRfMmutGmPHtjVob

That’s probably a scam. I’ve bunch of WIFs with partial matches in sequence, be careful not to waste your time there.



For those who think searching for WIF has some magical twist—let me tell you, it's much slower compared to generating an address directly from a private key (hex, bytes or dec).

@nomachine, maybe let the curious minds DM you directly -: this thread’s starting to feel like a rerun marathon. Grin Let’s save the scrolls for fresh stuff!



-- Sim results

If you sum the number of checks over 10k simulations you get this :

Code:
=== FINAL RESULTS ===
Sequential: 495816995
Prefix: 496059807


WHICH IS ALMOST 50-50!

And maybe I have conducted the most experiments on prefixes, whether it be in the form of base58 or hash160.
Through these experiments, I have consistently encountered a 50-50 probability of outcomes.

but the basic aspect has already been demonstrated, which was the probabilistic success rate.

Well done! But let’s be real—if we’re talking probabilities, I Still remember, how you got yourself stuck in this argument when you trying to defend someone. Your heroic moment, huh? Maybe now’s a good time to snap out of that mess and chase some actual probability breakthroughs.

=== Configuration ===
Total numbers: 2,097,152
Block size: 4,096
Prefix: 3 characters (16^3 combinations)
Simulations: 10000

=== FINAL RESULTS ===
Wins:
Sequential: 3736 (Average Win Margin: 42.57%)
Prefix: 6244 (Average Win Margin: 36.55%)
Ties: 20

Total Checks:
Sequential: 10,472,126,509
Prefix: 10,548,477,557

Bro demonstration is over now! lets reduce the talk in this forum that we can easily read important posts Grin And thanks for searching all 10 digit seeds for me  Kiss

It doesn't use my cores. I only have 4% out of 100!!!

(4% out of 100%) Shocked, may i know how many core you have ?
The modification I suggested, which limits the multiprocessing.Pool to 60 workers, was necessary to avoid the ValueError: need at most 63 handles caused by the Windows API’s limitation of 63 simultaneous processes.

Try this:
Code:
with multiprocessing.Pool(min(cpu_count, cpu_count - 2), initializer=init_globals,
                         initargs=(shared_counter, shared_found_counter, total_seeds)) as pool:

Or try experimenting with a smaller chunk size, like 1 million or 100,000, to see if it improves utilization,, Smaller chunks allow more frequent task distribution to workers, which can help keep all cores busy  Roll Eyes

Right now I am doing GPU Cyclone version, it has hashing and comparing to target hash160, on rtx 4060 it has 4.3 Ghash/s, that faster than bitcrack, vanity, etc.

Hey, I’ve got the SHA-256 part nailed down in sha256_gpu.cu, but I’m hitting a wall with RIPEMD-160 in ripemd160_gpu.cu.

Right now, my RIPEMD-160 code outputs 499d42dd5724b7522a1c4bd895876e1232957cbe for SHA-256("abc"), but it should be 8eb208f7e05d987a9b044a8e98c6b087f15a0bfc. I’ve been digging into BitCrack’s ripemd160.cuh for clues—tweaking byte orders and round functions—but I’m still stuck.

Would you be willing to share how you’ve implemented RIPEMD-160 in CUDA? I’d love to see a working ripemd160_gpu.cu

Doubts about what ?

My Honest Doubts About the Puzzle Solutions – A Response to @Bram24732’s Claims on Puzzle #67 and #68

In recent weeks, the Bitcoin puzzle-solving community has been buzzing about @Bram24732 — the individual who claims to have solved Puzzle #67 and #68 back to back in just 67 days for #P67 and 46 days for #P68, using 2,000+ GPUs. Now, he's also encouraging others to join a crowd-funded GPU pool, claiming that even higher puzzles can be cracked this way.

Let’s entertain this hypothesis:

The puzzles were originally created by someone with long-term foresight and significant resources.

That person seeded the puzzles with real Bitcoin, perhaps as a clever marketing stunt or social experiment.

Years later, that same person (or group) resurfaces, pretending to “solve” the harder puzzles, when in reality they are simply revealing private keys they already have.

Why?.......... Huh............. To build credibility — and convince the community to join their GPU crowd-fund effort.

The crowd-fund ends up renting vast GPU fleets, possibly tied to their own interests or hardware partners — all while not actually scanning the keyspace, but instead using pre-held keys to simulate “success.”

Could This Be a Hidden Marketing Tactic?

This could be a strategic move by:

A GPU manufacturer trying to drive demand for high-end cards

A mining hardware reseller(ETH shifted to staking  Roll Eyes)

Or simply the original puzzle creator who now wants to profit from the community's belief that these puzzles can be cracked with brute force.

Why We Should Be Skeptical

Solving Puzzle 67 in 67 days is mathematically implausible with 2,000 GPUs.

Solving Puzzle 68 just days later makes it even less believable.

Pushing for crowd-funding and renting GPUs after these “successes” looks like a classic setup:

First, show fake success → then sell the dream → finally monetize the crowd’s hope.



@Bram24732 You openly asked the community to share any doubts, and I’m simply responding with an honest, analytical perspective based on the facts and numbers available.These questions and theories are already circulating within the community, and rather than letting them grow in silence, I believe it's better to express them openly and constructively.

Congratulations!! @Bram24732 for Puzzle 68!

Huge respect for cracking it—amazing work!

To the entire community: as we all know, there are no magic tricks, shortcuts, or secret exploits here. It’s now clear that pure brute force is the only way forward.

With that in mind, it feels like the puzzle journey has reached its end for many of us. Competing against someone with over 2,000+ powerful GPUs (and counting!) just isn't realistic.

Still, it’s been an incredible ride. Much love to everyone who participated, explored, shared ideas, and pushed the limits.

It is possible to upload executables (.exe) to GitHub (closed source) if they are 100% your own work. Encrypting the private key (pk) also infringes the license because, in a way, you are indirectly profiting from it. In short, if all the code were yours, you could do it without any problem. However, if you include third-party code or libraries, check their licenses to understand what you can and cannot do.


Thanks.. that is what i want to know... you are saying that if i wrote 100% of the code myself, then i could legally upload an .exe and even encrypt private keys function. However, if i used third-party code or libraries, i need to follow their license terms.

I understand your point. I did write the majority of the code from scratch, but I used several dependencies and repositories from him for faster address generation, such as
"sha256_avx2.h", "ripemd160_avx2.h"  and "SECP256K1.h"... etc, The rest of the code is entirely mine.

Given this, what would be the proper way to proceed? Should I remove the repository entirely, or is there a way to comply with the license while keeping my work available?

You just need to make the repository private, remove the .exe file, and rebuild from scratch the files that are not part of your audit. After all, what truly matters is the logic, and ideas like "sha256_avx2.h," "ripemd160_avx2.h," and "SECP256K1.h" are not protected by patents safeguarding their logic. Simply rewrite anything protected based on your understanding of the idea and in accordance with the licenses. Some of these may simply require proper attribution to use without modification, depending on the license terms. However, another option would be to give up and simply delete everything, as the culture of donations has practically disappeared (99% dead), leaving only criticism alive.

I understand your point, and I appreciate the guidance. Making the repository private, removing the .exe, and rewriting the necessary parts is something I can consider.

But honestly, it’s disheartening. The fact that the culture of donations is '99% dead' while only criticism thrives speaks volumes about how things have changed. Maybe that’s what pushed me toward the encryption function in the first place—though I now realize it was the wrong approach.

At this point, deleting everything might be the only real option. There’s no point in dragging this conversation any further. Let’s just end it here.

And before some random keyboard warrior jumps in with their detective skills, let me make one thing crystal clear—there’s no source code available for any of them. So, if you have a problem with that… well, you know what? F*ck off!  Wink

I hope you're aware you are breaking the GPL license of the JLP projects, making your software illegal to distribute in binary form.

In short, you're the one who should f*ck off, since you have a problem with intellectual property.

Can I release a modified version of a GPL-covered program in binary form only? (#ModifiedJustBinary)

No. The whole point of the GPL is that all modified versions must be free software—which means, in particular, that the source code of the modified version is available to the users.

Seriously, I had no idea about this. I honestly don’t know what I’m doing wrong legally, what the consequences are, and how I can correct it. As a long-time member of this community, I genuinely want to fix my mistake—so if I’m in the wrong, I’d appreciate some guidance.

Is it really unfair to upload only .exe files on GitHub? I’ve seen many repositories without source code, and I’ve even used some of them myself. Also, is it wrong to encrypt private keys for solved puzzles as a way to earn a small reward for the effort we put in? just help me understand the right way to go about this.


Man, it's a bit contradictory to ask for free help and then try to monetise what's been openly shared. The whole point of public repositories is collaboration and transparency. If you're thinking about encrypting private keys or keeping only executables private for profit, you might want to rethink your approach. Open source communities thrive on trust and the sharing of knowledge for the common good, and monetising that in a closed way can really go against the spirit of things. Perhaps try to find a balance or explore ways to give back before turning things into a money-making scheme.


f*ck of these puzzles........ Years of hard work, countless sleepless nights... and what did I get? Not success, not respect—just legal troubles and a whole lot of stress. Truly living the dream!......... Built castles in the air for years, only to be handed a demolition notice.

And you call this an open-source program? What do you say about that—is it fair enough?

I just saw this in the original Git repository from the Cyclone author:
Code:
#ifdef _WIN32
    #include <windows.h>
    #include <winsock2.h>
    #include <ws2tcpip.h>
    #pragma comment(lib, "ws2_32.lib")
    #define close closesocket
#else
    #include <unistd.h>
    #include <arpa/inet.h>
    #include <sys/socket.h>
#endif

This code sets up the necessary includes for network programming. With these headers, you can create programs that send and receive data over a network using sockets.

What is the purpose of this setup? Is it for sending keys over a network or something else?  Tongue

I don’t know… We will see.  Grin

I already mentioned this on GitHub, and today I Gonna revealing it but i am too late. I sincerely apologize for not disclosing it from day one.




There’s just one thing I did—if a full match is found, you receive an encrypted private key that requires a password to decrypt. In return for providing the password, I only ask for a small appreciation fee. Is that really unfair? You guys can tell me. Many kind-hearted people would definitely share something, but not everyone does.



From my experience, once people succeed, many forget everyone who helped them along the way. They don’t mention you in their success, and that’s just the reality. Still, I truly apologize if this has broken anyone’s trust. It’s not about deception—it’s about the hard work we put in, only to end up with nothing when the final moment arrives. #WP Sad

You’re free to use it if you like, or let me know what I should do. Should I just delete my repo?

In this benchmark, you get an average of 4 Mkeys/s per core, possibly because this version uses a fully random approach, which impacts the speed.

The biggest performance gain comes from generating eight random numbers simultaneously using AVX-512.

Code:
__m512i randVec = _mm512_set_epi64x(rng1, rng2, rng3, rng4, rng5, rng6, rng7, rng8);

Of course, I won't publicly disclose the exact details of how this works. Grin

You know what? My system said, 'Let’s try it!' Cool … And guess what? It’s running absolutely fine. But me? I’m the one getting hanged multiple times while playing around with Cyclone.  Embarrassed

Forked this repo 4 times, applied my 4 favorite logics, and everything is working perfectly!
In these processes, I faced tons of bugs, challenges, endless AI conversations, and way too many forum posts—seriously, that stuff sucked the life out of me! Cry

One of my forks includes stride logic—I saw you mention somewhere that stride doesn’t work properly above 32-bit or something like that… Well, My stride version is unlimited and working flawlessly with zero issues.

Anyway… no more stress—I’m just gonna chill now. And as you said, I’m off for some fishing too! Cool

Oh, and just a heads-up—soon, all 4 forks will be available on GitHub, so get ready because you guys are gonna love this!  Kiss

And before some random keyboard warrior jumps in with their detective skills, let me make one thing crystal clear—there’s no source code available for any of them. So, if you have a problem with that… well, you know what? F*ck off!  Wink

If you wanna use it, great! If not, here’s a complimentary finger from my side.

I ain’t your babysitter, and I definitely don’t have time to argue with those saying, 'OMG, you put viruses in your .exe!' or 'You're trying to steal our few satoshis from our wallet!' 🤦‍♂️ Bruh… take it or leave it—I’m just here having fun! Cool Cool Best Wishes to Every One Kiss
