1000 gpu 5090
Could find 71 or 135 within 7 days
Hardware not only enough, need to use mind +strategy
Too


What is your search method that allows you to scan the vast key space of Puzzle 71 within one week?
There is numerous strategies in my mind and practical
Just giving u tip,
If using bitcrack, there is some other function too example
Share 1/2 etc,
Don't stop here, there is forks too pinkachunka ver, bitcrack2 ver etc, something could be use in them too
Not first step
71 have 18 char
4 char from 4000 to 7fff contain 16000
1000 gpu will use share function in between here
2nd part 14 char, now think n calculate starting point generated by bitcrack, 14 char need to adjust in between starting points*1000 gpu
Hope here 80% solution help you think and design for find 71

Thankx for make valuable app
I see in match prefix and jump to
If you set an other option like
Run sequence to 1000 then jump to 10000 and in between checking 1000 match prefix print to file
Example command
-check 1000 -j 10000
Instead of first match prefix then jump
This will use product one an other angle
Hope this feature make product more better and workable

If you have 5090 gpu
Can someone explain, for search complete range of 48 bit, how much time by bitcrack or keyhunt etc sequence search ?

In my view
1000 gpu for 7 days enough to find 71 puzzle,
You always calc full range search, maybe that's wrong
7days with 1000 gpu with logic search could be resulted

Give me 1000 gpu access, hope I could find earlier

Focus!!!
density by a factor of 10, from 0.001*length(key) to 0.01*length(key).

Can you explain this better with a some practical example?  Embarrassed

Here is a practical example:

https://github.com/NoMachine1/Cyclone/tree/main/PUB

No AVX2, no algorithm, nothing. Just raw Point and Public Key search. If you want it even faster, you have to brainstorm and work to change SECP256K1 and to science the shit out of this.  Wink
Need multiple pubkeys load by file and  search...

In back posts I saw someone calc prefix count based on bits
Can some one tell me how much could be 19vk prefix in 69 bit range ?

I repeat request for add function in cyclone
Where we could check list of hash160 instead of only 1 hash160
Example switch -f hash160.txt
More default -b 4 should be ended, if need apply -b, if no need then user don't apply -b switch for buildup speed
Thankx

I use this only on Debian Linux because I don't like dealing with Windows.

So you don't play games.   Tongue

The last game I played was Prince of Persia from 1989, so you can imagine what dimension I'm in  Grin
From 1084 to 1990 each n every softwares games, programs languages etc I still have, in original form of floppy disk, even that times security of programs for not a copy, creator design to set some data fix at floppy sectors, only original program could install from original floppy, I still have all in original form

My guess is 69 key is even

Have you tried to make cyclone version with load of list hash160 instead of 1 h160
And speed effects ?
If still not worked...
Could you try to develop this version for load of hash160 list

you should already be rich enough to participate in this puzzle.

So, honestly speaking, this puzzle was made by a rich person for rich people—the rich will get richer, and the poor will get poorer. Right?   Tongue

Yep... Or maybe you manage to use vast.ai for free by hacking their system—exploiting 3,000 GPUs, stolen credit cards, or even the puzzle creator himself, as you’ve already written somewhere. The problem is, you could end up in prison. It’s better to just go fishing. Grin

I found this haha ​​it's a joke  Tongue
Hash160: 61eb8a50c8673cd3fd9d73ee90c733ff24b6e64f
BTC Address: 19vkiEajf1jD23km6G6DdSQXH2VhWP3kHG

I found this one:
PK:   19665F6056877D8B5B
Public Key    : 02502C2518C06231BDDACA06491E0B790DB9478B56B8DCD2E255CA7E7380E97267
Found Hash160 : 61eb8a50c8673c376c4bdb96d179afecaadbd140

I'm very curious about the distance between the 2 addresses.

I have too
Found Hash160 : 61eb8a50c86b......  1 piece
Found Hash160 : 61eb8a50c86.........  3 piece
This could help you to found distance close to key ?

Hello everyone. I have published my optimized versions of VanitySearch (CUDA) with speed boost in case anyone is interested  Smiley

The "bitcrack" version is specific to the puzzle and allows searching for addresses and prefixes (compressed) within a given range. The speed is about 6900 MKey/s on a 4090 and 8800 MKey/s on 5090.

The second version, on the other hand, performs a standard search for vanity addresses (not just P2PKH compressed) but with the same optimizations in terms of math and CUDA code. Random searches with endomorphisms.

https://github.com/FixedPaul/VanitySearch-Bitcrack

https://github.com/FixedPaul/VanitySearch

Thanks! Grin
why not multi-gpu?

The "standard" version allows multi GPUs

The "bitcrack" version does not. since the range size is a power of 2 the number of GPUs must be as well in order not to have overlapping keys. It would also be slightly slower because the threads of one GPU have to wait for the threads of the other to finish, which is a problem if the 2 GPUs do not have the same speed.

It was a choice to keep things simpler and a little more efficient Smiley
Cuda 8 version available?

Cyclone last update
By default 6 prefix, thats reduce speed to half
Even we select or not prefix,
This area effect speed
Is showing off your cyclone every day useful for solving problems?Let's study the GPU carefully.
Solving problem is not based these app
Solving problem required math, and proper apply inside these app
