Bitcoin puzzle transaction ~32 BTC prize to who solves it

[zielar]

There is nothing "hacked" so far. The Distributed Pollard Kangaroo algorithm is known since 2000.

Let's get some numbers for the 90 bit challenge:

BitCrack runs at about 715 MKeys/s on Tesla V100 - look here.
If we remove hash160, the rate would be 1430 Mj/s. Mj here stands for million kangaroo jumps.
The algorithm has expected run time 2*sqrt(b-a) jumps, here b-a = 2⁸⁹.
This gives expected running time of 09:39:55.
Looks quite fast.
Of course this is just a probability, if lucky, the time goes down to 3-4 hours, or not lucky, then time doubles to 18-20 hours.
Or really unlucky, with triple the expected run time - 1 day 04:59:47.
Since the algorithm scales linearly, one could use multiple V100, let's say 8, resulting in expected time 01:12:29.
The price for 8x V100 in google cloud is $15/hour.

Someone having 20x RX 480, each running BitCrack at 107 MKeys/s.
Using the same assumptions that would give 214 Mj/s each, for a total of 4280 Mj/s.
Please note, that for complex code AMD OpenCL compiler is very, very bad, and the system might crash, or even worse, bug the computations.
Assuming 150W per RX 480, the system would consume 3kW.

Of course these numbers could easily double when unlucky.
And someone else could solve it before, then it's all a loss.

You forgot to add that these calculations concern the execution of the script using the POLLARD KANGAROS method which has nothing to do with the BitCrack key search method. The implemented / ready solution to finding a key using the POLLARD KANGAROS method is not available anywhere, so it is only in the possession of people (I suspect that countable on the fingers of one hand) who wrote it themselves. Being in the possession of this solution - running it on any computer will be a million percent more profitable than any computer equipment of modern times. BitCrack for every next address needs 2x more time to scan the entire scope. For my example - # 64 will occupy with my equipment (over 100x TESLA) - full six months, so presenting the table information about breaking # 115 through the eight GPU in two hundred days is firstly - misleading, and second - a perfect example on what difference we talk between BitCrack and Pollard Kangaros (which is the only one that can refer to this table [I do not know - I do not have {so I do not check}] whether it is reflected in reality)

taking this as a reference : " # 64 will occupy with my equipment (over 100x TESLA) - full six months"

we can draw the rule (estimated for over 100xTESLA):
case #64 0.50  year
case #65 1.00  year
case #66 2.00  years

case #n  2^(n-65)  years

It is still called "the 32 BTC prize"  but the prize is really more than 100 BTC ...

Contests and puzzles are always interesting. But I, as a regular user, would like to get a greater guarantee of payment in case of winning. It will be very unpleasant to waste your time, and then, get nothing.

What would you like to guarantee in the world of cryptocurrencies? That is the fact that the one who has the private key - the means belong to him. Anyway, wait ... I have a guarantee for you ...

So basically stealing someone's Bitcoin? What if you had that 32 BTC and someone stole it from you, what is wrong with you guys? This is such a shitty community that you guys would call someone's own hard-earned Bitcoin a "prize" and even bounty it. You are the reason Bitcoin has such a bad wrap.

The owner of these Bitcoins spent them to low entropy private keys on purpose in order to test the security of the Bitcoin system.  He wants everyone to try and take them.  He then issued a spend transaction from some of the addresses in order to test the security of low entropy private keys with spend transaction.   He did all of this on purpose in order to test the system.  For helping with this test people are being paid for their efforts.  This is not stealing it is people being paid for a service.

The money is who first finds the key. If I find him first - I deserved him ... hard work on finding him. So end up fucking and accept that you are a poor man who has his whole life groaning and has not done anything in life and has no chance to find the key, because he has nothing ... because he groans and groans instead of earning anything ... and that's what you do not deserve anything ... and life is just in this respect, because it will not be yours!

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!

Just a reminder for those who joined us here lately ...

This guy, saatoshi_rising, is certainly the creator since he moved the range  161-256 as promised on July 11th 2017
 

Thnx, by the way has anyone tried using AWS for this?

okay, if there's no secrets on private keys for bitcoin puzzle wallets,(if choosed randomly)

how it's puzzle wallet then? it's not puzzle, it's just searching for luck for the one random of keys between trillions of keys.
we can't solve , because there;s no secret in it, but we can keep searching and try our luck, is not?

Just read the thread instead of asking same questions over, and over, and over again. Once upon a time it was not clear what this transactions is all about and this "puzzled" people, from this came the Title of this thread. After some years everything was cleared and creator of the transaction confirmed what community already concluded about it. "Puzzle" is for historical reasons, not meaning something can be solved like normal puzzle.

Your question could be answered by reading the very first post in this thread.  Do that.  Did you do that?  I am betting not.

Perhaps the title of the thread should really be "Mysterious Bitcoin Transaction" but instead it is "Bitcoin puzzle transaction".

i did not read that bro, sorry if i am wrong,
can you share the link of it, i am interested to read.

but the creater of the bitcoin puzzle transaction had told us, there's no pattern on keys on puzzle wallets no secrets ,but just a random numbers/keys is not it?

Folks, can anyone suggest please any good and precise big numbers equation solver? Software or online, doesn't really matter...
