Well and how he from a transaction the public key received? sent a bit bitcoin to the address? What prevents him from doing the same thing with 56? I gave him an approximate search space.

To use the baby-step giant-step algorithm you need the actual public key, the address (P2PKH) is not enough. The public key is exposed when someone (e.g. the owner) makes a transfer out of the account.

Only issue now is to compile Vanitygen in Windows.I know this as a benchmark for my own calculations. we'll see soon Who will succeed. I'm not likely.

you are wasting your time.  The person who created the puzzle has already posted exactly how he did it.For step n you do not need to search for any possible solutions from step n-1

I've read most of this thread and am absolutely mesmerized by everyone's knowledge of the inner workings of things. I would love to be up to par with everyone on this. so who wants to tutor me and/or provide a link to something that explains more in-depth?

Not exactly. He just mentioned that values are random. But randomness can be very different.
If you look at the table with keys 1-55 you'll see that keys tend to sit in second part of range.

Unless and until they don't.  The selection of key is totally random within the range with all values equally likely.  Seeing or creating "trends" in random data is a very human thing to do but unfortunately for your theory the private keys for each range were created by having a computer create a 256 bit secure random number and then masking the result down to the desired key length.

If you search the top half of the range for any key there is exactly a 50% chance of the key being in the top half of the range.

Our family was terrorized by Homeland Security.  Read all about it here:  http://www.jmwagner.com/ and http://www.burtw.com/  Any donations to help us recover from the $300,000 in legal fees and forced donations to the Federal Asset Forfeiture slush fund are greatly appreciated!

Nobody admitted the find, so private key is unknown.

The private key is 0x6abe1f9b67e114

Code:
Private key : 000000000000000000000000000000000000000000000000006abe1f9b67e114
Public key  : 85a30d8413af4f8f9e6312400f2d194fe14f02e719b24c3f83bf1fd233a8f963 eb400323654cec63999b56f4ba44e8b21ab92d9d697fabe4666df3678585669

I do not understand all this, If I'm smart enough to do this, it would be nice to do it. Would the author be a miner? This also raises the question whether someone else rather than the author did cash out

The selection of key is totally random within the range with all values equally likely.

1. There is no true randomness in computers.
2. Can you count? 30 keys from 55 were in second half.

But OK, I've counted myself just now and was expecting a bit more than 30/55 chances

WOw that is really tiresome puzzle i would recommend you to take some photos and pictures on how you came up with that given so that we can fully understand on how are we going to crack that puzzle. I know that would lead to an account holder with huge money on it. Well let me help cracking that one but i need more data regarding the puzzle.

Maybe somehow the word (passphrase) tear out of the private key. Grin Or there only one way, you can select 64 characters hexadecimal system and this will be a private key, you can get the same address through the word but through the address we can not see this word. As the author of a puzzle in general he scattered keys in space If he did not select the address manually. Or he has a hardware wallet (deterministic). How can we repeat the principle of his puzzle just like that scattered at the same addresses. Or was it an isolated case in the history of the universe?

All the private keys for each range were created by generating a 256 bit secure random number and then masking the result down to the desired key length.  You could easily create a similar puzzle if you had enough Bitcoins to do it.

It would have been so much bitcoin for me i would not be sitting here.

And how this process looks, you can also generate a random and add "maskin". Something he wrote 000 0002...

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.

If we can not think of anything other than scans of addresses, then it's like diving into the lake and farting there to stun and catch fish. To find 56 by scanning you need 100 1080ti cards and it will take a month or more. For the next step you need already 200 1080ti with the same time either increase the search time.

There is nothing to "think of anything other". The point of the puzzle is not to be cracked, to prove that it can not be crakced. When private keys even from this limited range of numbers are uncrackable, the ones from full range are absolutely untouchable. Bitcoin is safe. That's what anonymous author of the puzzle is telling us, and he backed his claim with all these BTC. If he is wrong, someone would pick the money from this puzzle. Fortunately no one could do it, and no one will ever be able to do it. As long as this puzzle is not cracked - we have nothing to worry about.

After 4 years (maybe even earlier) when the reward for bitcoin dropped Instead of mining bitcoin will go in search (something similar LBC with Chinese capacities) of lost millions of bitcoins then this puzzle will not last long. However a clever mathematician with a calculator would have found a way to puzzle now not necessarily accurate mathematics but all sorts of paradox.

Well, this is actually challenging for those who are accustomed to deciphering secret codes. I'm sure that only an intelligent person can do this right, organize the puzzle correctly to produce something meaningful. But, unfortunately I am not a part of the solution. I do not have much time to think about the challenge. Maybe the hackers who are experts in breaking the bitcoin wallet can do that, ha ha ha. That’s a bit of my opinion.  Maybe, I will offer this challenge to my friend who is very good at computer software. Good luck and I will share these results with you all.
