And who prevents you to narrow a range of search?
For search the private keys for address 62 is selected keyspace 2000000000000000 - 3FFFFFFFFFFFFFFF
In this space it is possible to find about 2305843009213693952 variants.
The project has started for a long time, therefore it is possible to assume, that about three quarters of addresses is checked up and among them no required.
I.e. it is necessary to you to check up 2305843009213693952:4 = 576460752303423488 variants
Can try to begin with 3800000000000001

- keyspace 3800000000000001:3FFFFFFFFFFFFFFF

If this quantity of variants 576460752303423488 you divide into speed of generation of keys of your computer that receive a rough operating time

Good luck!

62   2000000000000000 - 3FFFFFFFFFFFFFFF
63   4000000000000000 - 7FFFFFFFFFFFFFFF
64   8000000000000000-  FFFFFFFFFFFFFFFF

Hi, folks! Great topic!
Need some of your guru's help. As far as I understood, if we have i.e.
61. 00000000000000000000000000000000000000000000000013C96A3742F64906 - 1AVJKwzs9AskraJLGHAZPiaZcrpDr1U6AB
62.                                                                                                                      - 1Me6EfpwZK5kQziBwBfvLiHjaPGxCKLoJi
63.                                                                                                                      - 1NpYjtLira16LfGbGwZJ5JbDPh3ai9bjf4
64.                                                                                                                      - 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN
65. 000000000000000000000000000000000000000000000001a838b13505b26867  - 18ZMbwUFLMHoZBbfpCjUJQTCMCbktshgpe
means that privat keys for #62, 63 & 64 will be somewhere between 13C96A3742F64906:1a838b13505b26867. Am I right?
If yes, how can I narrow the keyspace for #62 only? Even approximate range I believe will be ok fo try. Can a simple hex math be used in this case?
Sorry if its a noob question.

We already know exactly how the author of the puzzle generated the private keys because he told us exactly how he did it right here in this thread.

The private keys were made by taking a random number and then masking it to the desired bit length:

#1 = 256 bit random number bit wise ANDed with (2¹ - 1)
#2 = 256 bit random number bit wise ANDed with (2² - 1)
#3 = 256 bit random number bit wise ANDed with (2³ - 1)
...
#60 = 256 bit random number bit wise ANDed with (2⁶⁰ - 1)
#61 = 256 bit random number bit wise ANDed with (2⁶¹ - 1)
#65 = 256 bit random number bit wise ANDed with (2⁶⁵ - 1)
#70 = 256 bit random number bit wise ANDed with (2⁷⁰ - 1)
#75 = 256 bit random number bit wise ANDed with (2⁷⁵ - 1)
...
#160 = 256 bit random number bit wise ANDed with (2¹⁶⁰ - 1)

So, there is no pattern to be discovered.

Yes I understand.
Just thought - what if .....

I said "code", as in "source code", this is printout from the output.

He just have an overstatement. OP did not say anything in his thread regarding with payments. However, if you just look at the title Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it. You can emphasize also that he will pay 32 BTC as a reward for those who solves the puzzle. I think all the address will never been located or determined because even those are in blockchain, all users have anonimity. in short, we can hide ourselves but we do not know if there are pros that can locate the IP.

BTW, I do not see here any code that deals with private keys with known public keys, #65, #70, #75, etc, which were moved to expose public keys. Is that code public at all?

for machine's memory is 600GB
at least this code need update:
uint32_t entry = xst.n[0] & (HASH_SIZE-1);
to
uint64_t entry = xst.n[0] & (HASH_SIZE-1);

and update
typedef struct hashtable_entry {
    uint32_t x;
    uint32_t exponent;
} hashtable_entry;
to
typedef struct hashtable_entry {
    uint32_t x;
    uint64_t exponent; //this will take more memory
} hashtable_entry;

I do not know English - I use GOOGLE TRANSLATER.
I shall try to write. As on a condition of health I can not work on the computer more than three hours per day.
At me the very weak computer (the processor AMD A6-3420M APU with HD Graphics AMD Radeon HD 6520G) - gives speed only 0.63 MKey/s
I use the CPU (-d 1), not the video card (for software clBitCrack.exe)
Really I can search in a range with accuracy
FROM - XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX0000000001:
TO - XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXFFFFFFFFFF

Here all meanings X for each of 54 positions should be known, i.e. I can search only in the first 10 positions
Therefore I am compelled to search for other method to narrow keyspace of search in hexadecimal
For this purpose I have seen(overlooked) all found variants and has counted factor of increase (step) from the previous address to the next.
The positions from addresses #50 up to addresses #70 were interesting to me
For this purpose I each position of "grown-up" of the address I divided into a position of the "younger" address.
In a result I have received such factors (K*):

Accuracy of "hit" rather high and the error makes no more than +128 addresses.
But factors (steps) have the very large difference:
Minimal - K*1.2561547139608029
Maximal - K*3.3687335859160928
I think, that after addresses #61 presumably factor will be even more in a range from K*4 up to K*6
It is possible, that the organizer specially has arranged addresses with balance with such different steps.
My idea has appeared " complete delirium "!

can some one help me  bulding BitCrack on linux ?

I am not selfish and I remember someone if somebody helped me. If I manage to take the next wallet - you can be sure that I will not miss you when sharing the prize :-)

5-10 percetn from found prize  Jock 
Good luck.

Thank you so much.... Now that's working.

Sorry
Before string

insert

example

9.c: In function ‘main’:
9.c:107:2: error: ‘tim’ undeclared (first use in this function); did you mean ‘time’?
  tim = localtime(&tt);
  ^~~
  time
9.c:107:2: note: each undeclared identifier is reported only once for each function it appears in

Just for a fun little "thing" : for those frustrated by how long this takes.. someone could sort out how long it would take with a gpu and bitcrack and now it suddenly looks like a month is no big deal.

After string
insert
showed percentage at generated array. Where 1000000 each showed. May changed.

After string
Insert
showed percentage each 10000000 try searched.

I'm sorry, friend, but this is a pool of many identical matrices ,not one, so it's not gonna work.
