Bro i advise you to stop wasting you money, for fast bucks ( puzzel ) because  the hashing power which is required to solve one piece is very big, with the money better buy shitcoins, or rennt hash power for mining. But if you know how to use baby step giant step algo just buy amazon server with big amount of ram and go on it  Also feel free to send me tip xD (just kidding)


So how we calculate specific hex range for 64 for example and the possible variatons of 64 is calculated  2^65 - 2^64 = right ?

Edit: Is it have someone who have for example all 22 bit adresses generated and checked for funds ? Maybe have more puzzels or adresses  in these ranges with funds ?




Wow you get with r9 280x 20mh or 20 Milion Keys/s . I dont think you can get only 20mkey/s thats pretty small try to play with -b and -t  - p parameters  try something like this  -b 32 - t 256 -p 1024 and post results. Also my list have only 255 adresses of the puzzel and use -c ( compressed mode) its seems when you put so much adresses the speed drops hard. Also update you amd drivers to last .

Offtopic: Someone who know VHDL here , please tell me is it possible fpga adoption of bitcrack algo ? And if it possible with Xilinx Virtex-7 FPGA VC707  what speed can get ?

So LBC also watch all generated keys and check 4 funds ? Are u find some other puzzels like this or this is the only one ? Anyway you do great work with lbc i watch the project since 2018 summer  and always thinking for fpga priv8 key mining but still think is useless. I hope u big project to be 160bit key bruteforce Are u think its possible to bruteforce 160 bit key for example  first adresses where satoshi mine blocks  with current hardware tehcnology ?

English is not my native language and sorry for mistakes.
Rico666 i watch you work long time  ago and its so good, but what about bitcrack adoption to your pool ? Why not ? It will have moar power and we can solve puzzel really fast ? I think this is the next stage of bitcoin soon or later pepople will start to brute keys, also im wondering is it possible to adopt fpga cluster to mine keys what do u think ?

My calclulations :
63 bit key all combinations = 9223372036854775808 2^63 ?
for 1 day you can calclulate  3214080000000000 keys
9223372036854775808/3214080000000000  = 2869.6771819166840302668259657507 days
Am i wrong  with calclulations ?

Are you use something like pool for all videos or what ? I have some ideas for adapting bitcrack to pool , but i think its useless because we dont know is it have more puzzels like this or more adresses like this for bruteforcing. I try to brute 86 but with no sucess still.. I get only 50Mkey/s even if i clock my video.....

Edit: how much cards and what period of time to brute 63 ?

https://github.com/brichard19/BitCrack/releases

If you video card is nvidia download cuBitCrack.exe
If you video card is  amd radeon download clBitCrack.exe

example command line options  -i check.txt ( file with adresses for check) -o gold.txt  (output file with founded adresses)  -c  (compress each adress)  -b 32 (blocks) -t 256 (threads)  -p 1024 --keyspace  ( key space range in hex example 00001:00003 ) --continue save.txt ( save current work to continue after start up)

Edit: use last drivers if you have nvidia download cuda 10 if u have amd download last avibile drivers

Interesting, what speed you have on what video card? I have rx560oc and reach only 50Mkey/s acording my calculation if you scan all 62 bit range is so much years. Are you scan small pieces of 62bit range or all ? Thanks


Edit: Sorry for my bad english,it isnt my native language.
