Topic: Bitcoin puzzle transaction ~32 BTC prize to who solves it - page 203. (Read 215272 times)

OP would have no interest in revealing the PubKey from #66 to #75 today it would be almost automatically discovered. The goal of OP was to demonstrate the solidity / resistance of BTC in the face of the ingenuity and the very power of a community!

for puzzle #66 if the pubkey was revealed it would take about 2s with an average
#67 4s / # 68 8s / # 69 16s / #71 1m etc of course subject to identical key location  and using average material

for #80 with average hardware kangaroo it takes 1 hour to find the privateKey .

I must admit i gave up seeking solutions for those puzzles. It consumes to much time and gives nothing.

I've tried 125 with BSGS and Kangaroo  ... i've tried 66 in random mode ... and my conclusions is: These numbers are just too big for seeking with home computer.

Even the topic name is misleading here - These are not PUZZLES ... there is no puzzle , no pattern , nothing. Just massive random numbers. With current hardware possibilities it could be solved but we need massive amonut of hardware to do it in a reasonable time.

It should be called something like "Computational Power Competition" or "Bitcoin Benchmark" not a "puzzle".

The only thing that can be solved by an average person are puzzles about maybe 90 - 100 bits but only in case the creator will reveal the public keys. But then solving puzzle 66 is a matter of few minutes and only competition is who will notice first that the public key is available ( and I doubt that was the goal of creator of all this thing).

When you realize with how big numbers we deal here and what is the speed of our machines the only solution is to give up.

Of course one would treat this as a lottery but considering the power consumption and ultra low chances to win  a (let's be honest) not that big reward (its significant amount but not a life changer) i doubt it's worth it...

Anyway it was useful experience from educational point of view.

good luck

you too busy to judge my opinion bro, look at the WORKING TIME it's say 00:00:00s, i run this command took 5 second to DONE. you know i mean right ?
so why you just think it's so instant ? if this so fast? why you need to run the command manualy, so ?  
Kangaroo 1 second ?


Here's the right RANGE if you mention me about the wrong range.
i have more range nonce about the pubkey 65.

Results,

When playing with some iceland tools which is https://github.com/iceland2k14/kangaroo i got this speed on CPU
 

• [24894.64 TeraKeys/s][Kang 28672][Count 2^29.29/2^29.10][Elapsed 06s][Dead 1][RAM 53.4MB/46.0MB]

Is it good bad fake idk but like i know iceland tools are good

You are using a wrong range. Puzz 65 is 17 characters not 8

Puzz 66 range in BSGS would take an hour  a few minutes at most.

----

Btw, is anyone trying their luck with puzz 125? The only discussion i see going here is about 66 lol. Looks like 125 bits is too big to give any kind of hope.

Lol…what is this?! You ran a 30 bit range in 5 seconds?! Kangaroo can do that in 1 second with CPU only.
Where did you run 65 bit? And those results?
Y’all need to stop unless I’m reading everything wrong lol.

I never found the BSGS-CUDA running on linux/debian, still use the Windows version, There's the github you can download the BSGS-CUDA windows and already compiled.
you just need extract the zip, and put the exe on the same file.

test your luck here, it's safe no random malware.

I try to scan the #65 Puzzle with BSGS-CUDA, using GTX1650Ti [Testing the 30 # puzzle]

only 5 seconds.

IMO imagine the puzzle maker show pubkey the #66 Puzzle, maybe it's take the same time like 10-20 seconds haha.

is there any existing BSGS-CUDA linux version available which I could install and try ? I cannot find anything on github. I found a BSGS-CUDA which is Windows only and even then you would need a licensed PureBasic installation for running it. Any linux build available ?

for me, it's faster BSGS CUDA

ok, but it's still awesome, only if the kangaroo worked according to my ideas, it would be a different coffee

No no no, that is for 10 x 3090 GPUs

that speed is interesting 1 day 100 bits public key crack is impressive for one graphics card

are there any comparisons available in relation to speed and success between BSGS-CUDA vs. KANGAROO-CUDA ?

If at 1200 MK/s = 2.27 days
If at 1500 MK/s = 1.8 days
If at 2000 MK/s = 1.4 days

Also, you said 100 binary, I took that as a private key/pub address in the 100 bit or 2^100 range.

maybe it's arround hundread mkeys no ones tell about the speed of 3090, but i have a proof about my GPU 1650Ti running BSGS-CUDA

I scan and i got 380-370 Mkeys average

maybe you can check this youtube video, he's trying Kangaro with 8x RTX 3090 on Vast.ai

https://www.youtube.com/watch?v=1BHNer9dZ_M

I don't know, I'm asking, but let's say it goes at a speed of 2000 mk/s

What is the speed of a 3090 running kangaroo?

how long would it take to break 100 binary long private key for kangaroo
I'm asking because I don't have the computing power
let's say you have a 10 gpu rtx 3090, you can write an approximate time, how quickly they would be able to solve it

I know right, still same, we need the public key, because no public keys mean more time.
