2548/2 = 1274
2548/10 = 254.8
2548/100= 25.48
2548/1000= 2.548

next
10 - 2.548 = 7.452
....

Looks like a math from primary school Grin

Do you write in English by yourself or you use translator? It is difficult to understand you because you do not use full sentences, just a few words all the time.
At the end - what do you say you are able to accomplish? Find private key from public key (on any range)? What database you have - database of public keys in some range? Please, for the moment, think what you want to write and write it down slowly and carefully, maybe use google translator if you need.

It is also possible to track how much the first digit of the password is.

It is better to ask Zielar directly. For sure he had access to 300+ GPUs. But we are not sure he owned them by himself, it was also possible he used the "company's assets".

Why is this important for you?

I was just curious that's all, I don't really feel like bothering him just for a trivial question like that.

I want to work with a programmer who can weave kangaroos.
I made a calculator that can calculate the public key.

How would this help finding the private key?

Zielar has/has access to 300+ of the V100s; and he is the one who solved 110 and 115, so that is just kind of the benchmark used to compare how long to solve 120.

Man I wonder where he gets all those V100s from.

I don't know anyone mass buying V100s; it is just the example used to solve #120 because that is the type and number of cards that were used to solve #110 and #115.

I feel like #120 is going to be solved by large numbers of older cards lying around in people's garages somewhere, rather than with anything that can be rented with AWS or Vast. Even 100 of any high-end card just seems too expensive for someone with deep pockets to rent in the long run and you can get better results searching with a few thousand of people's Maxwell and Pascal cards (and even Radeons if Kangaroo ever gets ported to OpenCL).

Well, it will be me so I can tell you they are all RTX 20xx and 30xx, but I am using 1 GTX 1060 and 1 GTX 1050Ti to do the tedious work. Wink

EDIT: I'm not running it full time, just here and there, so anyone really has a chance.

256 card x Tesla V100 32GB is close to or around 300 billion keys per second. I'm going after a 256 bit key with cpu now.

Can 256 card x Tesla V100 32GB try with 64 bit puzzle #64 still can not crack in one day.

and still can not crack 120 bit puzzle #120 by kangaroo

need to discover other algorithms more

No, it would take up to 2 years or a little bit more to search the whole space of 2^64 with 256 card x Tesla V100 32GB.

Why are people still mass-buying V100s to throw at Kangaroo, when it doesn't have a deficiency like Bitcrack has?

IMO, it makes sense to splash on T4 or A100 cards which are fraction faster than the V100.

Or is it because most vendors are still stuck selling V100 GPUs and don't want to invest on newer GPUs? It's the only way you could possibly get a hold of 256 V100s in the first place.

last night I test run kangaroo python script version all night with puzzle #120 it is not work good

Did you really think you would solve it overnight running a slower python script??

For each tame, there is a wild to solve the key. If you would stop mixing hex with decimal I would try to explain it better but I'm not going to convert them back and forth. I'm still not 100% sure what you do not understand or what you are trying to figure out. But I will tell you, you may get lucky and solve the key using python script only using a CPU but the odds are low; on average it would take thousands of years to solve.

Do you know how many pairs of tames + wilds can solve a key in a given range or is it just 1 pair that can solve a key?

I'm not 100% sure but if you use DP = 0 (meaning every point would be saved) then I would say every tame has a wild that would solve the key. If one used a different DP, then it would depend on how many of those DPs exist in the range. Example, if one used DP 32, in a 2^64 range, for every tame DP of 32, then there would probably be a wild DP of 32 to solve the key.

Range is too high and too wide for a reason...Billions of dollars in wallets/private keys. If it was too narrow of a range, no one would use Bitcoin.

It's all relative to your GPU/CPU power. You can't have one GTX 1050 and expect to find keys in 120 bit range over night, or over a decade. But if you have many GPUs, then you have a chance to find keys after time, depending on your GPU power.

challenge is too big for 256 bit it is can not possible find

challenge what maximum we can do on records, will be stuck with 120 bit forever same 256 bit or not?

if can do 120 may be can use up to 140 bit or some 2-3 level, do far from 160 bit

I think all random method is stuck on too high range, next method may be concern about calculate or mix

last records is 256 card x Tesla V100 32GB right, How many power for GPU need to solve

I try kangaroo cpu only is difference with GPU over 12-15 time, kangaroo require to use with GPU

you must use %s , not %d

Improve and optimize the project "Kangaroo , VanitySearch " , maybe requires several years of learn VC++

Thank you

Yes, I need to learn C++ more

kangaroo is powerful random search

I think kangaroo need to modify to haves new feature can find key

or some tools like GPS find zone ok key and use kangaroo scan, now range is too high too wide range

other way is new one algorithm power more than kangaroo

Range is too high and too wide for a reason...Billions of dollars in wallets/private keys. If it was too narrow of a range, no one would use Bitcoin.

It's all relative to your GPU/CPU power. You can't have one GTX 1050 and expect to find keys in 120 bit range over night, or over a decade. But if you have many GPUs, then you have a chance to find keys after time, depending on your GPU power.

you must use %s , not %d

Improve and optimize the project "Kangaroo , VanitySearch " , maybe requires several years of learn VC++

Thank you

Yes, I need to learn C++ more

kangaroo is powerful random search

I think kangaroo need to modify to haves new feature can find key

or some tools like GPS find zone ok key and use kangaroo scan, now range is too high too wide range

One problem is that when it goes to save I get an illegal memory operation and it shuts down. The few times it did save the save work was 1.5 GB (a whole lot of points) and after the 2nd or 3rd save it would get the illegal memory operation so i just have the save work for 3 days. i don't want to do the entire keyspace on these larger puzzles because the electric could go off or some other issue and have to start over, rather just do a smaller slice. The smaller keys did not do that because it found them before 3o seconds and 50 is not that big of a keyspace as 120

You shouldn't get a memory code on save. Here's what I would do. Run the precompiled version and see if it does the same thing; see if you get memory error or the MK/s rate is the same.

It's always better to do the whole slice, not smaller ones because you will actually wind up doing more work/longer run time breaking it up into smaller chunks AND the biggest issue is, you really won't know if the key is in a smaller slice unless you let it run for 6+ times the expected operations and even then, you still may not know.

What is the link to the compiled version. I will try it, must be the 256 bit version for comparison, that is the one I am using not the 128 version.
