#2 released

Added support for compute 5.0 and compute 7.5
~20% faster generation of starting points
~1% kernel speedup

https://github.com/sp-hash/Bitcrack/releases/


Can you help me, your version of bitcrack doesn't see uncompressed adress. I have made test list with 2 000 000 adresse, and Bitcrack finds compressed adress well. I started with different option
  • --compression BOTH
  • -c -u
  • -u

Even starting bitcrack with -u options doesn't help. It can't find uncompressed adress

I am not sure if it is the best place, but I receive many emails with question about my WifSolverCuda - NO, it cannot be used for finding 32BTC puzzle coins. Converting puzzle into WIF with missing end is not a good idea, it will not work! Apart of fact that it is one more layer added, my program is developed for WIFs with missing end/middle.
The same with CPU version WifSolver. So please, do not ask me about it anymore  Wink

Just to add something to the list - one may check my patched version of Kangaroo, where one may test given range with a stride, so for example check only even or odd keys.


Can you optimize program for random search or maybe help to write a python scrip for randomly search?
Only your program support Segwit(from 3) and Berch39(bc) adresses. And also can use CUDA.

And another quesion. Is this adresses also generating from the same space of numbers as P2PKH keys? I mean, that for example I have a private key
-snip-
For this key I have two P2PKH adresses  1AxSQFHqQ2nFUbZwcWSmHYrYumuQnK2nYG 12b9TofPY9R5gtKRUHBWjQrNP6mBYZuFqr. Can I generate also P2SH adress using this key?
The first address is generated from the uncompressed public key pair of that private key.
The next address is from the compressed public key.

More info here: learnmeabitcoin.com/technical/public-key

Why BitCrack doesn't support new types of adress? (from '3' or 'bc' starting)?
Probably because it's designed to bruteforce the "puzzle transaction" (link), and the puzzle's addresses aren't p2sh nor bech32.

Thanks for everybody for explanation.
And any tool to take participate in loterry? I want random bruteforce of all keyspace, at a database of all BTC adresses with balance

I think about Hashcat, but it doesn't take secret exponent, in can bruteforce onli WIFs

Ладно сейчас попробуем другие криптовалюты. А в чем проблема у меня с cgminer при копании биткоина? Комп не успевает что-ли получить шару?

Да, не успевает. С такой мощностью в сети биткоина надо года 2 на нахождение шары. Пока он её вычислит она уже устареет и выплаты за неё он не получит.

а как тогда на Kryptex работает, они что не биток майнят?

24.23Mh/s - это чрезвычайно мизерный хешрейт для копания биткоина.
Видеокартами биткоины не копают. Видеокартами копают те монетки, для которых не сделали асиков.

Да понимаю, но как писал выше, для личного опыта, просто интересно попробывать покапать как биток так и даш, эфир. Помоги пожалуйста с настройкой cgminer. Я так понял он не может достучаться до пула?

P.S. кстати у меня есть еще 2 компа по 40 мага хэшей каждый. думаю за недельку накопают биток на 500 рублей

помоги пожалуйста

Привет. Решил испытать что такое майнинг, для личного опыта. Скачал cgminer 3.7.2. Все сделал по инструкции, такая команда cgminer -o stratum+tcp://crypto.mine.nu:9332 -u bitcoinaddress -p x --expiry 1 --scan-time 1 --queue 0. Видюха греется но при выходе не фига не нашел, ни одной шары. Вот что пишет при выходе уже и то что при работе

Работа:
