Bitcoin puzzle transaction ~32 BTC prize to who solves it

The profitability of Puzzle 67 can be assessed using AI, and it turns out to be quite profitable, maybe even 68.

At a speed of 7 Terrakeys, approximately 1,750 RTX 4090 GPUs with undervolting to 350 W would be required.

🔹 Power Consumption:

Total power: 612.5 kW
Runtime: 67 days (1,608 hours)
Total consumption: 984,900 kWh
🔹 Electricity Costs:

USA (0.19 USD/kWh): 187,131 USD
UK (0.318 USD/kWh): 313,198 USD (≈244,686 GBP)
These costs vary by region and tariff, but the USA and the UK remain among the most expensive places for electricity.

1,750 RTX 4090s rented for 67 days or bought is more than puzzle 67 price.

If the GPUs are free for them—let's say it's some AI organization whose computing power the solver has access to—then paid rental is madness.

he is obviously lying, lol

[kTimesG]

For those who didn't catch on this yet, the 67 solver wants to use RetiredCoder's skills to go after 135, since the amount of computing power to break 135 is pretty much what he used to break 67.

Or he wants to rent the GPUs to him to make up for his losses, lol.

Hi @zahid888. I am curious about this from last year.. I even write some python script to try to understand this, but still didnt get that :

It’s just a few lines of code, bro—why overcomplicate it?  Remember, it’s only for generating the starting point!

Below is full demonstration & Code

Demo:

Code:

If you do the calculation, puzzle 67 solver only realized a lot of losses,
67 days x 24 hours x several thousand GPUs = more than puzzle 67 price. I think that's why he is not giving any donations right now.

There’s a big difference between someone posting a youtube tutorial in 2005 and someone introducing an idea at the right time and right place, @Wondrig philosopher didn’t just share information—he brought forward a solution when it was needed the most.

Innovations aren't always about inventing something entirely new; sometimes, they’re about applying knowledge when it is truly needed.

Anyway...

Hi @zahid888. I am curious about this from last year.. I even write some python script to try to understand this, but still didnt get that :

Hey Bro, welcome to the black hole! Just a friendly reminder—if you win, I definitely expect an appreciation fee... Fair trade, right?

Interesting idea! I’m not quite sure what benefit it brings me yet, but it’s definitely something new. I ran your script, and bitcrack worked at full power on my RTX 4090, reaching about 3Gkey. Previously, I was using my own BAT file, which only gave me around 500Mkey. In any case, that’s already a noticeable improvement!

My batfile for bitcrack example:
_{cuBitCrack.exe --keyspace 6AF70BC6066336300:6AF70C160F7BF3B00 -o 2.txt 1BY8GQbnueYofwSuFAT3USAhGjPrkxDdW9}

If my idea helps you succeed, just remember me in your victory speech! A little ‘shoutout to the genius who made this possible’ wouldn’t hurt... or at least a ‘thank you’ in small print at the bottom of your success story! BTC BTC Also accepted ... have a happy hunting..

If... then as a token of gratitude, I have no problem sending you a reward, just like the creator of the bruteforce program that will help find the key. I don't mind giving 1 BTC out of more than free 6 BTC.

OMG! You’re so kind—Wishing you all the success! But remember, don’t let this consume all your time and energy. Stay focused on your main work, because real success comes from consistency, not just luck.

To all newbies: treat this as a side quest, not your whole adventure!

Thanks for your response @zahid888. I am overthink about this for almost 2 year.

From all logic including magical pattern and everything. only your approach about seeds that got my attention beside the random logic things. because when author said the key was totally random without pattern. the only thing to find it is through the random too (computing power and some luck also needed ). but the random isnt just random right ? there's some seed / entrophy in it... My questions is, how do you know / determine about 5 to 20 possibility starting point from such seeds ?

If i ever find the key.. 2 btc will hit your wallet right away  

[brokedummy]

I am running Bitcrack on my 3070. The most I can get out of it so far is just under a billion keys/second. Do ya'll think this the best it can do or could it be improved with better settings or better software? I'm using -b 256 -t 256 -p 512, I've tried a few other variations but it never got any better than this.

Sure, bla bla bla...

Unfortunately we won't have the pleasure to hold you accountable for your blabber.


Marathon Digital Holdings announced their Slipstream service around February 22^nd, 2024. In their investor relations post they don't talk about a non-public mempool explicitly. Lots of yadda yadda about how "special" they are and offering an unique service no one else offers, yadda yadda.

It was talked about on whatnot crypto coin news sites as Bram24732 indicated. Maybe not immediately with the property of a non-public mempool for transactions submitted to slipstream.mara.com. From very crude search I've done, initial focus was more on the topic of non-standard transactions. I'm not sure if MARA actually needed their service to have a non-public mempool. Anyway, I think their main motivation is to provide an unique service where they can charge at least double or more Tx fee rates than by normal block space competition.


First mention of Slipstream to my knowledge in this forum was here, https://bitcointalk.org/index.php?topic=5487786.msg63775224#msg63775224 by FinneysTrueVision. About two months later again by ABCbits here, https://bitcointalk.org/index.php?topic=5495707.msg64052681#msg64052681 in the context of being able to submit non-standard transaction that won't otherwise be transmitted by other nodes and subsequently mined by miners. Search hits via ninjastic.space and search for "slipstream.mara.com" in post body. I might've missed other posts.

It's true that WanderingPhilospher was first to elaborate about Slipstream service as a means to counter transaction sniping bots. Kudos to him for actually using his brain cells to post something valuable in this thread, in contrast to the bs we have to endure here for quite some time.

I wonder what puny contributions the pay-WP-gratitude camp and other near-zero-value posters here have given so far? How about compensation for the nonsense, conspiracies, magic voodoo or other non-sensical crap you've spouted here?

You can chill now, my sporadic rant is over. I'll populate my ignore list in the hopes that I don't catch brain cancer by following here.

It's basically useless. McDouglasx is just an enlightenment teacher. You can find the link you want from his homepage.

There are very suspicious transactions regarding finding the 67th wallet.

Example: Graphics Cards rented with stolen credit card information
It just proved that this is not related to any software or hardware.

Thank you for showing that it can be cracked with MONEY even with the worst software. Of course, if you really did it with such a serious investment or expense. I definitely do not think that a few thousand graphics cards were rented with their own money.

Let's do a simple accounting.
In 67 days, they have to spend at least 250-300 thousand dollars to crack the 67th wallet. When the remaining amount is divided by the total number of partners, 50 thousand dollars remains. (Average)

So, would someone write "WE GOT RICH" on Twitter for 50 thousand dollars?
