If you had something else than screenshots in there I might be able to tell you why your number of keys/sec is low

ok, as i tell
split range to chunks
do complete ECo in jacobian, then sha and ripemd
baby steps, montgomery batch...
optimize cuda to work with warps
compare with hash from address
both for compressed and uncompressed, so that is full search, no skip, no false positive/negative
no missing ranges...
and yes, if you skip sha and ripemd, if you know public key then can be handled for rtx 3080ti ~1-1.5Bk/s, with fast reject, 2/4
and if you know public address then not need to check compressed/uncompressed all is clear

You can reach about 4Bk/sec on a 3080Ti, address checked, post sha and rmd. Without skipping any key.
If you want feedback on your tool please post code and not screenshots.

Is this puzzle still available and does someone have the latest information to start solving it?

Looking forward to giving it a shot!

Yo, welcome to the circus
Love the enthusiasm, but lemme save you some time and electricity, my guy.

Puzzles 67 & 68?
We’re talking custom-built software, load-balanced across like 30,000 GPUs, all running 4090-class speeds, no overclock fairy dust, just raw industrial-grade insanity.


Puzzle 71?
Straight up frozen in carbonite.....
Nobody’s got the GPU count or the spare electricity budget to even justify warming it up. Candles remain unlit.

Puzzle 135?
Same vibe. Same pain. Same nope.

Everything past that?
Extraterrestrial tech only
Ancient aliens, quantum unicorns,
Mercury in retrograde, stars aligned, miracle on standby.

Mercury in retrograde, stars aligned, miracle on standby.

I’m on the streets of LA, vibrating at the wrong frequency, absolutely certain this puzzle was going to prescribe me something FDA‑approved. Instead I got an answer key and the knowledge that the pigeons were laughing at me.

Unfortunately I wasn’t participating in this forum during the Satoshi/Finney era, but something tells me they saw in Bitcoin the seed of a revolution that would transcend economics—something that would revolutionize science as a whole. As a scientist and a carrier of a neurodegenerative disease, I imagine Hal Finney was looking for answers not only to a decentralized, egalitarian financial system but also to equitable means of pursuing truth (consensus) in general. If he were among us, I feel he would be engaged in DeSCI projects using AI scientists, in an effort to accelerate the discovery of treatments—or even cures—for neurological pathologies, since those would also be answers for creating models of artificial consciousness. Perhaps the very advent of blockchain is a piece of the AGI/ASI puzzle. Perhaps Satoshi left Bitcoin in good hands to carry this Great Work forward, supporting other decentralized projects anonymously. Perhaps we are facing a puzzle far larger than merely breaking BTCs by brute force…

ok, you have it
sha256-ripemd160.cu

Looks like a basic port of CPU code,
Am I missing something ?
Also I don’t see any EC math or host code ?

you ask for sha and ripemd, that is not cpu code...

Exponential pubkey for P130 after reduce to 125bits

[Bram24732]

https://github.com/Wrappp/Btc-puzzle-71

If you had something else than screenshots in there I might be able to tell you why your number of keys/sec is low

ok, as i tell
split range to chunks
do complete ECo in jacobian, then sha and ripemd
baby steps, montgomery batch...
optimize cuda to work with warps
compare with hash from address
both for compressed and uncompressed, so that is full search, no skip, no false positive/negative
no missing ranges...
and yes, if you skip sha and ripemd, if you know public key then can be handled for rtx 3080ti ~1-1.5Bk/s, with fast reject, 2/4
and if you know public address then not need to check compressed/uncompressed all is clear

You can reach about 4Bk/sec on a 3080Ti, address checked, post sha and rmd. Without skipping any key.
If you want feedback on your tool please post code and not screenshots.

ok, you have it
sha256-ripemd160.cu

you ask for sha and ripemd, that is not cpu code...

“Post sha and rmd” as in “after sha and rmd have been computed”
Not “please post the sha and rmd code”

Why don't you publish the source code on GitHub? So we all have a good foundation.

You said on Puzzle 67 you'd publish something, but you haven't.

And in Telegram chats, you said you'd show us how to make FixedPaul VanitySearch-Bitcrack faster!

RTX 4090 8 billion

And now you're saying 3080Ti 4 billion!

Why don't you do that? And share the source code with the community like all the other four coders who did.

[Bram24732]

Why don't you publish the source code on GitHub? So we all have a good foundation.

Because it's unreadable and unmaintainable. I'll upload that once I take the time to clean it up.
There are also a few things I want to make sure of first.

You said on Puzzle 67 you'd publish something, but you haven't.

I said I would publish proofs of work on Github, and I did, a few days after clearing 67.

And in Telegram chats, you said you'd show us how to make FixedPaul VanitySearch-Bitcrack faster!

My plan was to integrate my optimisations there, indeed.
Turns out it's quite a bit of rework of the existing code, so I didnt get to do it yet.

Also, everytime someone asks me a question on TG, I reply to it.
Every single time someone asked me about EC math or cuda optimisations, it quickly devolved into LLM BS, or the person didn't have the engineering level to understand my replies.
EVERY. SINGLE. TIME.
And believe me I answered questions from A LOT of people.

RTX 4090 8 billion
And now you're saying 3080Ti 4 billion!

Yea I did not check exact speeds for 3080Ti, but it's the ballpark (I was comparing to the 300M of OP)

Why don't you do that? And share the source code with the community like all the other four coders who did.

Because it takes time to do proper, and if I'm being honest most people here are ungrateful script kiddies.

I solved 67 and 68 using custom software distributing the load across ~25k GPUs. 4090 stocks speeds : ~8.1Bkeys/sec. Don’t challenge me technically if you know shit about fuck, I’ll ignore you. Same goes if all you can do is LLM reply.

oooOOOooo
Now I’ve realized who I’m dealing with — a new braggart has appeared on the horizon.

Let’s do a bit of math.

25,000 × RTX 4090 at a price of about $2,000 equals $50 million.

The reward for solving puzzles 67 and 68 is 6.7 BTC and 6.8 BTC.
At an exchange rate of, say, $80,000 per BTC, that’s around $1,080,000 — absurdity number one.

25,000 RTX 4090s consume 450 W each at stock settings, which results in a total power consumption of 11.25 MW per hour.
He probably has his own personal nuclear power plant at home behind the swimming pool — absurdity number two.

8 billion keys per second.

Puzzle 67 has 73,786,976,294,838,206,464 keys, multiplied by 2 for compressed and uncompressed formats.
That would take 4.27 days to solve.

Puzzle 68 has twice as many, so it would require 8.54 days.

So why is the time difference between finding the two solutions:
02/21/2025, 02:41:01 for puzzle 67 and
04/07/2025, 00:52:42 for puzzle 68?

Unless he celebrated solving the first puzzle and only then turned on the 25,000 RTX 4090s —
or had to go to an exchange office to cash out the reward in order to pay for the electricity.

Still, I have to thank him, because he motivated me to improve my SHA-256 algorithm:
currently 344.5 Mkeys/s, up from 273 Mkeys/s, on an RTX 3080 Ti (only one )

You might now know that but renting GPUs is a thing. I never owned any GPU used for this bruteforce.

8 billion keys per second.
Puzzle 67 has 73,786,976,294,838,206,464 keys, multiplied by 2 for compressed and uncompressed formats.

What does compressed / uncompressed have to do with any of this ?

That would take 4.27 days to solve.

I think we took a 1 week break before starting 68.
But the real reason it took about a month to break is because those GPUS we not all 4090. There was a mix of nVidia and AMD, and the slowest card I think was a 980. So the speed and power consumption were not what you've calculated, at all.

Still, I have to thank him, because he motivated me to improve my SHA-256 algorithm:
currently 344.5 Mkeys/s, up from 273 Mkeys/s, on an RTX 3080 Ti (only one )

Congrats, only x10 to go.
Now if you were a little bit less of an ass you might just post your code and I would give you feedback on how to make it faster.

uh you mix cuda and opencl... never mind
post your super code i will adjust mine

Not sure how that’s a problem ?

Not a fan of script kiddies copy pasting code they don’t understand.
Happy to educate and review your code though.

[GinnyBanzz]

I'm being led to believe that the actual key attempts per seconds shown in keyhunt-cuda is not real? On my laptop with a decent graphics card, its shows me 400 million/second, but various sources tell me this isn't the actual true number of key generations , public key creations and RIPE160 comparisons is accurate. Anybody got any info on this?

What's your GPU Model ? 400Mps seems ok for a mid range laptop GPU.
You can actually check the numbers yourself. Run 100 small size ranges with random keys in them, then average the time it took to get the key. You'll have a good idea of the "true" speed.
But I would say your "various sources" are likely full of shit
Let us know how the test goes !

Man you are a King ... of nothing

Not sure what you're trying to achieve there.
If you don't want me to review your code and help you out that's fine, no need to be a prick.

People should be aware that AI can only answer things based on existing public information pulled off from the internet. When it comes to crypto and the issues surrounding this puzzle, and any available tools, AI prompts will produce 99% garbage, because it lacks real human technical expertise, the kind that isn't noob StackOverflow answers on how to draw animated monkeys via CSS, which is what AI is really good at responding, ok? Make it count straight up 1 to 100, no skips, no stops, no errors? Nope, total failure. How can you imagine it will ever be able to come up with low-level code that computes 8.1 billion H160 per second on a 4090, if such knowledge only lives in the human brain (and in some unreadable code on somebody's machine, written by a human), and not in the public data that trained an LLM to recognize cats in YouTube videos, and now pretends to make guarantees about answering simple EC questions in a very wrong way?

This explains the continued BS over the subject.

This is true, but not completely. It really depends on the operator, how the requests are phrased, and how much time one is willing to invest. After several weeks of testing, rewriting code, and changing logic, I managed to produce a solid tool with which I’m scanning 135 using CUDA. Without AI, it would have taken me months, and I might never have achieved these results. It’s been running for a few days now—let’s see what it comes up with :-)
