How 63 bit puzzle a other low puzzles were solved?

[albert0bsd]

Hi, i search about it but i didn't find anything specific. So that is the question:

How 63 bit puzzle a other low puzzles were solved?

I did not mean which script or program was used, i mean  what hardware was used? also ask if it was luck?

Previous puzzles where solved time ago.

Here are my calculations about the time to scan All the range of each puzzle.

Code:

Puzzle 61 @ 1 Megakeys/s  (10^6):       36558 years
Puzzle 61 @ 1 Gigakeys/s  (10^9):       36 years

Puzzle 62 @ 1 Megakeys/s  (10^6):       73117 years
Puzzle 62 @ 1 Gigakeys/s  (10^9):       73 years

Puzzle 63 @ 1 Megakeys/s  (10^6):       146235 years
Puzzle 63 @ 1 Gigakeys/s  (10^9):       146 years

Puzzle 64 @ 1 Megakeys/s  (10^6):       292471 years
Puzzle 64 @ 1 Gigakeys/s  (10^9):       292 years

Please if im wrong in those calculations let me know.

Here are the private keys
13C96A3742F64906 puzzle 61
363D541EB611ABEE puzzle 62
7CCE5EFDACCF6808 puzzle 63

By example the puzzle 63 the privatekey is near of the end of the range, so if you have some hardware to search at 100 Gkeys/s it will take 1.4 years, lets to say that you are searching it in random mode and you have luck at 25% of the range that is 4.2 months and only if you have those 100 Gkeys/s.

Somebody know the history of how much time and hardware they use?

Sumary

Addresses from 1 to 50 puzzles were solved simultaneous by an uknow person/group
Addresses from 51 to 54 puzzles were solved by the the LBC project with variable speed from some 190 trillion keys per day
Addresses from 55 to 58 puzzles were solved by a Unknow person/group
Addresses from 59 to 63 puzzles were solved by Zielar with a speed of 248 Gkeys/s with bitcrack

There are interesting things in that Topic

Zielar talk about 0 costs of the electricity for him:

Speed of 248 GKeys/s are written here:
https://bitcointalk.org/index.php?topic=1306983.msg51808347#msg51808347

He use upto 100 GPUs Tesla
https://bitcointalk.org/index.php?topic=1306983.msg51848002#msg51848002

But in some previous post he only talk about 4 or 8 GPUs seems that he manage to get access to 100 GPUs at 0 cost for him

That is all that i want to know.

Perhaps you will find the answers in the very first topic of the puzzle.

Have you shown the calculations for BSGS or Kangaroo?

Ok, thanks let me time to read all the 80 Pages of that topic.

Have you shown the calculations for BSGS or Kangaroo?

is the Speed in keys/seconds and nothing more, i know that kangaroo solve the keys by  the birthday paradox but i understand that it need the public key to do that no?

the BSGS speed depend of memory, right now my version of bsgs can reach some Petakeys/s and yes it solve all those puzzles in seconds or minutes, but of course this is only possible with the publickey.

So if those programs need the publickey to have such ridiculous speed, how those puzzles were solved without having the publickey, well i going to read all the the topic thanks!

I will try to put here a decent summary for that

Regards!

Sorry, this is my mistake, these programs really need a public key.
Without a public key, only searches for Bitcrack and, possibly Vanitysearch.

Yes i already read some 60 Pages of that post and i found my question Answered.

I add a small sumary Answer to my post

110 and 115 with public public keys found Zielar too, if I remember correctly.

Yes that is right i read that history some months ago he do it with the JLP Kangaroo codes.

But he don't solve the puzzle 64  he said that it will take some 6 months with his  248 Gkeys/s in that moment and that puzzle not worth the time or effort. With that computer power is better mining than solve puzzles.
