Bitcoin puzzle transaction ~32 BTC prize to who solves it

[ars_pk]

Hello everyone! I've reduced the public key for puzzle #135 and created a database of 67 million public keys/addresses. I think I'm not the first, but no one has posted a database of public keys. This database contains two public keys/addresses in the 105-108 bit range (100000000000000000000000000:fffffffffffffffffffffffffffffff). This range is easier to brute-force.

The file xyz135rew_pub.txt can be used with keyhunt-Cuda and keyhunt in "xpoints" mode to find the public key.

Have tried keyhunt with 67 million keys with 30 bit or 40 bit to gauge the speed.

[kTimesG]

I've reduced the public key for puzzle #135 and created a database of 67 million public keys

Congratulations for "reducing" a 2**67 steps problem to a 2**80 steps problem.

Much better than the guy who "reduced" it to 512 keys / 2**72 steps a few weeks ago.

So who's next who wants such congratulations? I'm sure someone can do much better, maybe go "down" to one billion points, and "reduce" to 104 bits?

Maybe just reduce to 1 bit and search for the key directly?...

Do you even understand that if the key’s position is above 50% of the range, then half of your copies are a complete waste of time?

I can also create the required number of copies and even split them with the same difference — but what would that achieve? Exactly, a waste of time.

If there is precise information about where it is located, then it’s much easier to retrieve it than to brute-force all the remaining possibilities. And do you realize that you would need to reduce the total number of keys from 43556142965880123323311949751266331066367? Even 10% of that entire range is already an enormous number.

Your method isn’t new, and it brings no benefit for No. 135.

 Don't waste you time in keysubtraction, I have spend weeks understanding this and end up saying it is no use for 135 or higher range.
 The more you subtract the more keys you will end with.
 I am using 4 subtracted keys for 135 falling in range 40000..:4ffff... one of the key will fall in the said range and the others not.

You know what I'm about to say, right?

Congratulations for "reducing" a 2**67 steps problem to a 2**68 steps problem.

C'mon guys, really, no one yet with the 32 GB worth of reduced points? One of those will surely be in the 104-bit searched interval.

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.

You are quite right, 161-256 are silly.  I honestly just did not think of this.  What is especially embarrassing, is this did not occur to me once, in two years.  By way of excuse, I was not really thinking much about the puzzle at all.

I will make up for two years of stupidity.  I will spend from 161-256 to the unsolved parts, as you suggest.  In addition, I intend to add further funds.  My aim is to boost the density by a factor of 10, from 0.001*length(key) to 0.01*length(key).  Probably in the next few weeks.  At any rate, when I next have an extended period of quiet and calm, to construct the new transaction carefully.

A few words about the puzzle.  There is no pattern.  It is just consecutive keys from a deterministic wallet (masked with leading 000...0001 to set difficulty).  It is simply a crude measuring instrument, of the cracking strength of the community.

Finally, I wish to express appreciation of the efforts of all developers of new cracking tools and technology.  The "large bitcoin collider" is especially innovative and interesting!

Thank you @saatoshi_rising for this kind gesture, I appreciate you for making this puzzle an interesting one & for your funds you freely gave out to the community. In my humble suggestion, probably anytime you see this quote (that is if you would see it  ),  I humbly plead, you can make this puzzle more enticing by showing off the pub. key of some of the unspent addresses with a little spend maybe from the ± 101th key (± 101 i.e 2^100 - 2^160 keys or 2^99 - 2^71 keys), or keys with odd numbers (e.g key 71, 73, 75 etc) or keys with even numbers (e.g 72, 74, 82 etc) which ever you choose, at your own discretion or maybe randomly (e.g key 71, key 83, key 79 etc), probably between now and 2027 to mark 10 years anniversary you made this comment here    

This puzzle is now at a very very difficult state almost impossible state, cracking bitcoin is even harder (impossible), these facts has been proven to be true no doubt. This puzzle has been on for 10yrs + and some people that saw it from the onset are no more (I hope the OP of this puzzle is very much more since Last Active here is June 09, 2019, 07:10:05 PM  ) to see its end. I thank the heavens I am still around and will be to see the end of it  

I believe the purpose of this puzzle has been achieved 100% & facts proven to show bitcoin is like the Rock of Gilberta, it can never be moved   That being said, I oblige the OP @saatoshi_rising (and/or whoever that's in charge) to see this fun filled research come to an end in a short while by considering my request, my humble suggestion & plea.

peace & love

Give me a break! Just because you're too late to the solving party, you're asking for a low-effort, easy way to hope to grab some of the coins? Sorry, but that's bonkers and your proposal makes no sense and wouldn't prove anything new.

Disclosing public keys for puzzles in the 7x or 8x would be solved in mere seconds. There's nothing beneficial to ask for it besides you being greedy and lazy.

It's totally fine that we're currently in a situation where the grinding with currently known methods isn't quite economical. That's a worthy outcome for the likely purpose of this Bitcoin challenge grinding puzzle.

When known methods don't make it feasible, it's time to find something new if there's something new. Obstacles are a motivation to come up with something clever. And if there's nothing more clever so far, then this is also good to know.

Innovation doesn't come from an environment where things are easy going.

[0xastraeus]

In no way is this going to happen. Public keys have already been released for various puzzles, it's a shame you were too late to join in at that time. The puzzles you want public keys for will be solved in seconds. Releasing more will go against the whole premise of "cracking strength of the community."

Now it's just figuring out better algorithms, better strategies, and so forth. More public keys is not needed period.

Already happen when puzzle 161 to 256 coin shifted to 1 -160 puzzle
2nd happen creator funded more coins into these puzzle
No one can assume what's next creator do with these puzzle,
Due to price drop from 125k to 66k, may be creator fill-up more funds into unsolved puzzle, for  people's to try their attempt for saving
As previous talks on board last bit but sharing snario is pool, and no one talking about it too
Seems no one want waste time n money in pool base attempt definitely result would not fruitful
Only high reward will attract people to connect with this puzzle
Let's hope creator announce something better for community

if this one is in same 2⁷¹ Key space it may near to the puzzle 71? What if it does? i mean if it was in 71 bit key space...

When creator or whoever topped up puzzles #1, #066-#160 with 872.19BTC, worth around ~26.4 million $$, that's an exchange rate of ~30,286$/BTC, their investment to amplify puzzle's prizes was already quite huge.

And you guys seriously hope or ask for more, at now a little more than double the exchange rate? Hilarious...

I took the liberty to fix the topic's text, at least for my own post.

How does this hex private key fall in the 2⁷⁰ bit range for puzzle #71?

Maybe I had too much bear already, but I can't even get your public key from this PK.

[mcdouglasx]

Apart from what's already been seen in the last five pages of the thread, it seems that puzzles 71 and above are dead for the moment, mathematically and monetarily speaking, since it doesn't seem worth the investment, given the current price of bitcoin. I think only RC is trying something truly tangible apart from the homemade lottery game that the rest of us have tried, or am I wrong?

I think only RC is trying something truly tangible apart from the homemade lottery game that the rest of us have tried, or am I wrong?

You forgot to mention the fun and learning aspects with the incentive of possible monetary value.  At least to me it seems like that, a funny opportunity to learn something new with a prize attached to it.

Until 6 to 7 months ago, the only thing I knew about Bitkoin was to spell the name correctly.  I knew nothing about how and why it works.  And I started to invest a little bit of my time into learning how it works, who and how created it, why it has value, why it is secure, how address is created, what is the private key, what is the public key, etc.  Then I found this forum post.

So naturally I wanted to try my luck with it.  Every publicly available program I tried, I was not for some reason satisfied with it.  Had my ideas, wanted to implement and try them, but no knowledge or skills to do so.  Then I really poured my time into it, reading pages after pages after pages of endless code and explanations.  Trying Python, then C/C++ and CUDA.  Making Python code was successful, but it was so slow speed of address generation.  Python was not the solution.  Back again to reading pages after pages after pages of endless code and explanations.  Modifying existing tools like KeyHunt-Cuda, which went terribly wrong, but at least it was a start into C/C++ and CUDA.  After a huge disappointment, I said to myself "I want to try and make the fastest program that will beat any publicly available program when it comes to raw address generation".  And the path to the rabbit hole was cleared, and I slowly started to go towards it.

Ground up, starting fresh, making my vision into reality, new program had risen with my trusted 1080 Ti, first 450 million addresses compared in 1 second.  It was not the fastest, it was not the best, it was not correct, but it was mine, my idea.  Then 500 million, then 550 million, then almost 600 million.  Every time thinking this is it, it cannot get any better.  And all of a sudden 700 million.  Every time the speed increased the thrill kept getting better and better, pushing me for more and more.  I managed to get 800 million addresses compared in 1 second on 1080 Ti, and the thrill and happiness in that moment was, I cannot describe it.  Pushing the GPU to the limit unlocked 900 million on 1080 Ti, drawing 370 watts (of course no one sane would run the 1080 Ti at that power, but god damn it was good to see that MKey/s number on the screen).

Sadly, the 1080 Ti had to retire, it was a good GPU, it served me very well, but time did what time does and it had to go.  Right now I am pushing 3070 Ti with 2.04 billion addresses compared in 1 second.  Am I satisfied?  Hell no.  Will I ever be satisfied?  Hell no.  Am I thinking that it can get better?  Hell yes.  Looking at public programs, benchmarks, nothing can be enough.  More thrill, more fun seeking, more learning, more speed.  Fighting occupancy, register usage, managing spills, making sure the pipeline produces correct addresses, like I am in the Colosseum arena fighting the compiler and not in front of the monitor writing code.

If this challenge never existed, I would have never tried out the elliptic curve cryptography, SHA-256, RIPEMD-160, C/C++, CUDA.  And knowing the odds are against you with limited hardware or unlimited hardware, it makes it even more thrilling.  So the fun and learning aspects with a very very tiny possibility of finding a private key to some address, it is worth it.

So at least to me, it is very much "alive".

And you guys seriously hope or ask for more, at now a little more than double the exchange rate? Hilarious...

I took the liberty to fix the topic's text, at least for my own post.

How does this hex private key fall in the 2⁷⁰ bit range for puzzle #71?

Maybe I had too much bear already, but I can't even get your public key from this PK.

That hex value isn't the "Pk" private key( note
:lower case k associates with private keys and caps K for public) its the HASH-160 of the public key

So at least to me, it is very much "alive".

Amen. I have damn near the same story and I dont regret a single day of the time Ive invested self schooling, and learning, experimenting. Well said, indeed!
