I think only puzzle that easy to crack because puzzle create by using low bit with allow to crack

Reference bitcoin version 0.1 or alpha version start to use key 256 bit from first-time
That possible to not easy to crack it

Yeah I gave up on that after an hour lol

Here's an interesting random fact about puzzle address #120, in one whole day a Tesla V100 GPU can search 0.00000001% of the keyspace using the pollard kangaroo software. That is equal to approx. 2^93..


How long need for puzzle #120 address?
I will try you method tonight with 8 hour for check result test

Yep I updated my program so that it saves all the public keys to a txt file Smiley

And I've been running it all day with no limits from blockchain.com so I think for that specific api call there are no limits, but I could be wrong!


Thank you

Script it is work as well, I try already.

problem  Pollard's kangaroo ECDLP solver can use with only public key
and public key have only bitcoin address that have transaction

people know about this already, people smart to move bitcoin to new address that not have any transaction
and use new bitcoin address (segwit) not show public key , it have legacy only show public key

I'm pretty sure that means 256 x NVIDIA Tesla V100 SXM2 16 GB.

256 GPU's Shocked

OMG.

Thanks

I think both Pollard Kangaros  and BitCrack method use too much per of GPU
I will try method  Baby-step giant-step it interest, may be better than for who have low both GPU and CPU


now bitcoin  have high value may be someone can develop new algorithm for better brute-forcing  both public keys and address


Think for fun out of box
Can possible train AI. to crack bitcoin private key just some าำั not all key?
like training AI. to learn predict private key use deep learning
may be dataset is generate billion private key and bitcoin address put all to AI. learn
or using algorithm translate language to translate bitcoin address to public key (GPT3)
all method still using too high power of machine power to crack

Hi, WanderingPhilospher or anyone

reference with puzzle thread (update)
https://bitcointalk.org/index.php?topic=5218972.0

should be setup in.txt like this right?

Done I do correct?

publickey can be use both compressed and uncompressed right?

Hi, i am new

Just try BSGS
https://github.com/JeanLucPons/BSGS

Done Baby Step Giant Step has any version python script work like BSGS?
487  Bitcoin / Development & Technical Discussion / Re: Pollard's kangaroo ECDLP solver on: February 22, 2021, 01:43:47 AM
I pushed my little public key gathering script to github if anybody wants it!

https://github.com/GonzoTheDev/BitcoinPublicKeyGrabber

Could you help to write script to save output to csv collect?

Can blockchain.info use for get data massive over 100k address without get ban ip address?
488  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~100 BTC total bounty to solvers! ==UPDATED== on: February 22, 2021, 01:36:26 AM

Yes that is correct, the Pollard Kangaroo method can only be used when the public key is known, currently #120 is the lowest difficulty address with a known public key. #120, #125, #130, #135, #140, #145, #150 and #155 all have known public keys.

And yes if you don't know the public key, the only other option is BitCrack!


Thank you MeBender

256 Tesla V100 it is  same NVIDIA Tesla V100 SXM2 16 GB right

What about Nvidia GeForce GTX 1050 4GB?
490  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~100 BTC total bounty to solvers! ==UPDATED== on: February 21, 2021, 12:11:59 PM
I am new may be don't known a lot please advice

with Pollard's kangaroo ECDLP solver method
this way can crack bitcoin private key with only has "pub key" show available right
it can use with "pub key" on puzzle list

and for other bitcoin address on puzzle list, that without pub key, can not using Pollard's kangaroo ECDLP solver method

for other not has pub key must be use method brute-forcing Bitcoin private keys (use BitCrack or other)

491  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~100 BTC total bounty to solvers! ==UPDATED== on: February 21, 2021, 02:13:13 AM

Here is some good reading for you: https://bitcointalk.org/index.php?topic=5244940.0

Thank you $upermoney for advice.

I just doubt about series number of puzzle, it is pick by manual random or pick number by using some formula (using math) or some algorithm calculate for pick number

I try already with both Pollard's kangaroo ECDLP solver C# and Python3 script
seem is still random bitcoin address by method buy is random by curve line (not normal dot random)
that is good idea for using random by that method pattern, and yes it is better than random by normal one dot pick

(but that random not solve by calculate series number list)
I just think about puzzle challenge for calculate formula for pick bitcoin address  private key or not (create math formula series? or make challenge to random to found bit coin adress (pick by manual pric by hand)

How many people still work on this puzzle next address? ( How many people give up?)
look like both thread not talk a massive a long time

Hi,

Done any one still work progress random generate key for this bitcoin puzzle?

My question about puzzle

Series of this puzzle is not formula or algorithm right?

I think this puzzle is pick manual number by hand, I am correct right?

If this puzzle is number of some algorithm or formula it is can possible to crack it and if some one can solve this formula (algorithm) it can possible to get all bitcoin

But this (all address) is pick by random manual so this way never possible calculate by any formula , calculate, algorithm

Can anybody help to confirm me about all bitcoin address puzzle all take by use algorithm or custom formula for pick bitcoin address?
