Somebody please explain how it’s possible to get 200000Mkeys/s ?
I was fiddling around with the coding for cubitcrack which was stopping at “error misaligned address” so I ran cuda-memcheck cubitcrack to find the source of the error and first two times didn’t run
Then third time whilst it was compiling on the GPU simultanisously I ran the same cubitcrack in visual code debug and the cuda-memcheck started running but at excessive speed
Iam up to 360 868 335 716 192 in 30 mins... someone please explain how this is possible?
Only running one 3070 rtx.... help

I don't know about programming much
but I guess possible on photo that not search with bitcoin private key
may be modify bitcrack for some search may be search password or some thing
Mkey/s may be mean keyword not bitcoin private key

Now all brute force method bitcrack, kangaroo, BSGS all stuck with high rank of very very large keyspace

if scan all it use a time too much

We need to find the way and method to can calculate or guest right keyspace 
may be an help reduce from 1000 area to scan 100 area

use pubkey to caclulare direction of keyspace  and then use  bitcrack, kangaroo, BSGS

if can fine keyspace  low than 2^30 to 2^40 may be better ot less 1 days scan complate (Max 2^50)

(2^ 60 too high)

other puzzle no pubkey  still no idea what to do?

Anyone have any idea use pubkey to calculate keyspace  ?

To do brute force all area of keyspace in range it is not good idea?



Anyone an expert with python language please advice. Can you do Ai. on python?

I think about used version python scripts with all AI. api
it can possible to generate private key with address to as dataset and train Ai.
and do brute force by random with use call AI. model to give multiply value. something like that
just learn to read a lot about AI. deep learning.

Kangaroo so far is the only way to calculate keyspace with pubkey.

Brute forcing all area of the keyspace is a bad idea and a waste of time. Do you know about distinguished point (DP) method with kangaroo?

I also implement BSGS in C, in my tool Keyhunt, is not so fast, but the puzzle 63 can be solved in one hour or two. Also in minutes is you have some luck with  Random mode.

other puzzle no pubkey  still no idea what to do?

Puzzles without publickey are more slow, that is why puzzle 64 is stll not found.

I use my old GTX 960 and it literally solve 63 in less than a minute. If I want to use it to hunt 120, average 300 years. LoL. I guess if 64 with known public key and I use GTX 3060, I guess it can be solve in less than 15 seconds. That's also reason why if by chance you found 64, someone recommend to pay higher on transaction fees or otherwise once known public key, I believe those bot will attack in less than a minute.

Look at it this way, 50% of brute force on #64 = 2^63 operations while #120 only requires 2^60 operations with kangaroo.
If people aren't pooling resources for either brute or kangaroo or bsgs, then it will be a long wait unless you have Zielar's equipment then #120 is doable within 2 months +/-

There is a pool for #64 and I have tried to get people to pool resources with bsgs and kangaroo but I guess everyone thinks they can solve on their own.

And I believe you are correct, whoever finds #64 must pay high trans fee to get in into a block before someone else attacks it with kangaroo.

Is this speed based upon bitcrack or kangaroo?

It's based off of his BSGS version written in C# which is slower than JLPs version. Everyone who comes up with meet in middle or baby step giant step always claims high numbers, meanwhile, JLPs BSGS just keeps on being the fastest, with no hype 

[albert0bsd]

Is this speed based upon bitcrack or kangaroo?

Is just based on the speed that you get with any of those programs.

I just divide the Total of keys in each range between the speed by seconds.

By example the 120 bit space have 664613997892457936451903530140172287 total keys. Just divide that amount between you current speed the result are the seconds tha you will take, divide that bewteen 31536000 to get the numbers of years.

Is not based in my program or anything is just math.

Please if im wrong tellme, im open mind.

My program just reach some 1 to 8 petekeys/s in highend server and that is no hype.

Best regards!

It does depend on the program and how you are calculating the speed/s

Kangaroo versus a brute force with same amount of speed in key/s; it's not even close...Kangaroo would be finished smoking a victory cigar, started a family, grew old, and died long before brute force finished finish line

[albert0bsd]

Yes that is rigth Kangaroo is the fastest one. I'm still learning the Pollard rho algorimth.

There is a pool already running. I think someone did the math for 64 and still 1 out of 800,000 to find the key  after breaking the shares if I am not wrong. The pool is running less than 20 people, not sure about it. I don't think it's plausible to find 64 alone, unless someone is really lucky hitting a jackpot by using random. I have my own rig for Ethereum but far from enough to run Kangaroo. Even if I have enough to go for it, I prefer to choose safer path continue mining Ethereum because if you do the math, it has no difference putting 2 months for 120 and it's not a guarantee you will hit the jackpot. Just doing some fun things on puzzle, who knows I might be the lucky to hit jackpot since my old GPU can't mine anymore.

Just for your reference. Let's say you have 256 RTX 3080 with current price, you are going to get about USD 7.50 nett daily on each.

1 RTX 3080 = USD 7.50 nett daily
256 RTX 3080 = USD 1,920 nett daily
USD 1,920 x 60 = USD 115,200 2 months

I hear ya, no doubt mining = guaranteed money.
But if you had your 3080s and your friend had theirs, etc. etc. you could solve #120 quickly. But to just solve for #120 is a waste, IMO. Target 120 through 160, at least the range, then all wilds can be tamed and all be in the same range not in lower 1/32 range.

Also, if you have 256 3080s, mere 1.2 BTC is nothing and you are obviously in it for mining, but if you only have 1 and you have friends who have 1, that is the combining power effect where maybe you can net more than mining with 1 card. Who knows. It's fun, it's a challenge, next one breaks the world record...

The #64 pool is only as good as the number of people who sign up for it and actually run their rigs for awhile. But it is an enormous task, no doubt. Running same power with Kangaroo, the 120 would be found first.

Luckily I picked up Vega 7s when they were out and new. So it worked out, since they can't use the current programs to attack the challenge, they do the mining, 24/7 (still best in the market IMO) and I occasionally throw my 3070s, and 20xx cards in the mining mix when I want to get past a payout threshold or I am going to be away for awhile.

I don't have even 1 RTX 3080, lol. It's not worth to invest on 3080 buying at price gouging market. If you can get MSRP at 799 for RTX 3080, then you can BE in about 3 months. I have rig running 2060 and 2 x 3060 only. No planning to go for AMD card  because I have RX 480 rig and still running now, it's so noisy and higher power consumption. I did consider to buy a Vega 7s or 8s laptop especially I saw a guy post he can run like 5000++ mkey/sec with  Asus Zephyrus that day. If AMD card, I think RX 5700 XT is definitely a good invest if can get at good price. Unfortunately still lock down and unable to travel. I did check at some neighboring country, they do have stock and at a good price.

I also implement BSGS in C, in my tool Keyhunt, is not so fast, but the puzzle 63 can be solved in one hour or two. Also in minutes is you have some luck with  Random mode.

other puzzle no pubkey  still no idea what to do?

Puzzles without publickey are more slow, that is why puzzle 64 is stll not found.

Regards!

From calculations based

Anyone want to scan all , you can do it, scan till die, as you want LOL.

puzzle require to smart and better way, may be need to calculate zone, keyspace before scan and found in 1 hour or 5 hour something like that

if challenge scan found before you die, need to be change method to scan

ok, brute-force all may be absolute method to found but it use time a lot

may be I try puzzle challenge for a while and may be give up or back when recall or boring

still never have some news about someone can brute-force full key success

I think for now
Try focus on 9 puzzle that have public key for can use reference

Other puzzle not have public still like fly on space  (know only range information)

high bits puzzle need to fine algorithm or upgrade method great than now he have bitcrack, kangaroo, BSGS


Long term method brute-force from bitcrack may be strategy for solve puzzle
Absolute way solve puzzle

brute-force straight directly make waste time and use a lot of power to force
need to use smart calculate for brute-force

Some bad idea for spend bitcoin
Every one have some bitcoin on hand right?
Can possible with use dust bitcoin sent to random address that guess nearly puzzle and use it reference like use pubkey on kangaroo
use it like calculate phone location like mobile cell site

Like pubkey can help to solve puzzle high bits with kangaroo
I don't know may be not works
I think may be try to test play around
send some bitcoin dust I have sent to some address random on range and sent it out again to make pubkey
may be 10 satoshi or minimum dust limited with lowest fee limited


We have low power brute-force, 256 x tesla v100  still very very low power
Challenge is create massive brute-force for solve puzzle (idea lotto, still can do when bitcoin price still high should do before bitcoin price drop) but still limited with low bits

Don't over think it. Think long think wrong. Pick a path and hit it hard. Shooters shoot!

For the random piece, I have shrunk down the playing field and I have a 3 and 281 trillion chance every 6 minutes or so for #120.

There is no wrong or right way, you just have to pick a way that makes sense and you feel most confident about and go with it.
