Topic: == Bitcoin challenge transaction: ~1000 BTC total bounty to solvers! ==UPDATED== - page 42. (Read 57643 times)

For Pollard / Rho you need simple point additions.

Wikipedia: yotta 10^24 = 1000000000000000000000000

1 Yottakeys/s = 10^24 keys/s

How much is 1 Yottakeys/s for (Pollard / Rho) ?

With Pollard / Rho we calculate:


We can see here, how important a high keyrate is.

Truth. Hashcat will also give you the CU value, but I suggested it earlier, because getting this value would only involve downloading the program and running it :-) Much earlier I found this option and I already suggested this method to interested people, because it is the simplest, and the value of cu = value -b and better than this setting you won't find.

It's the first time I've seen a third-party (Thegrideon in this case) try to sell a wallet.dat cracker. I also haven't seen many people working on crackers for some time, so I'm a little surprised that their cracker has all these listed features: "mixed, dictionary and brute-force methods", "SSE, AVX optimization", AMD and NVIDIA card support out of the box which implies that the program has both a CUDA and OpenCL kernel.

Consequently, this makes me think they just bundled hashcat in their program with a little .NET wrapper for the GUI, no?

If that's true, it would mean the CU value might also be printed by hashcat proper. I've only paid attention to hashcat speeds, not CUs so I don't remember if they are logged too.

so try "cuBitCrack -l" oraz "cuBitCrack --list" for check CU. Maybe that command show you you ComputeUnits value

Thank You for the link, I am under linux not windows. I have compiled the cuBitCrack for linux.

Third column: bounty wallet address which is officially known from the Blockchain transaction available here: https://www.blockchain.com/btc/tx/08389f34c98c606322740c0be6a7125d9860bb8d5cb182c02f98461e5fa6cd15
Unless you mean the fourth: the upper rank limit. It's simple ... each subsequent rank is 2 ^ n-1 and the result of this equation is the value of the fourth column in DECIMAL

larocfra: please download the application available there from https://www.thegrideon.com/bitcoin-password-recovery.html (whether portable or installer). After running it, you will see the available devices at the bottom of the log window, among which the CU value will be in square brackets next to the GPU. The CU value will be the best value for your card as -b in cuBitCrack, set -t to 512. Now check what effect and show it off. All you need to do now is try to find the best -p value

Hi everybody,

I currently trying to solve the number 64 key, I have a Nvidia K80 water cooled and I am running cuBitCrack -b 88 -t 1024 -p 1024 -c -o foundkey.txt --keyspace 8000000000000000:FFFFFFFFFFFFFFFF

I have to run 2 separate session to be able to use both GPU on the card, I am getting 121.36 MKey/s on one target so about 240.00 Mkey/s total.

Do anybody have a setting to get more MKey/s out of the card ?

For the last two months - a large part of the text in the main post was invisible because it led to the server that was changed, which, combined with the fact that almost the entire topic is mainly composed of pictures (which I did due to the limitation of the number of characters in the post) - resulted in that's as mentioned above. This problem has already been fixed, and I will revive the topic by the way :-)

other way you can brute-force pubkey but pubkey  is long 34 alphanumeric characters  no body do this because  brute-force to private key directly is better if you do is double work for pubkey and still do with private key again it is waste of time

pubkey is expose when that address make transaction pay out

address 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN not yet use for payout so pubkey not expose

address 17s2b9ksz5y7abUm92cHwG8jEPCzK3dLnT already payout to other address is available pubkey expose

I really wanted it to work with number 64 but it is only possible when there is an exit. 

64

120
https://blockchain.info/q/pubkeyaddr/17s2b9ksz5y7abUm92cHwG8jEPCzK3dLnT

same just change address and see pubkey, if address had outgoing transaction

The creator made outgoing transactions from the addresses divided by 5 (..,100,105,110,115,120,125,... 160)
So, you can find the public key in blockchain: https://www.blockchain.com/btc/tx/17e4e323cfbc68d7f0071cad09364e8193eedf8fefbcbd8a21b4b65717a4b3d3?page=3

See the Index 11 (as outgoing transaction for 17s2b9ksz5y7abUm92cHwG8jEPCzK3dLnT), and you will find the public key in SigSciprt (use ASM format for better understanding)

here are as many public keys as possible.

you can use Kangaroo 2.2 to try to find private keys: https://github.com/JeanLucPons/Kangaroo

What exactly are you trying to do? Which program are you trying to tweak and what are you wanting it to do? If you tell me, I can help, if it's dealing with any of the VanitySearch programs

Severity   Code   Description   Project   File   Line   Suppression State
Error   C2065   'seed': undeclared identifier   VanitySearch   main.cpp   185  

3 errors, otherwise build successfull. but now not,

 "%02X",(unsigned int *)( &my1ch)); i added this

so instead, sscanf(&seed[2 * i], "%02X",(unsigned int *)( &my1ch));

instead of the original.          sscanf(&seed[2 * i], "%02X", &my1ch);

otherwise nogo? with or without unsigned int*)
using visual studio 2017, sdk 10.0.19041.0 (v141)
thanks

i compiled it fully, with a few add's some changes that's all.
        unsigned char my1ch = 0;
        sscanf(&seed[2 * i], "%02X", (unsigned int *)(&my1ch));

the line above sscanf has got the same unsigned char but needed unsigned int those 2 fixed thanks guys sorry for all those questions..
