Well, no one is going to mine a bitcoin using the cards that are used for the puzzle so you have to break it down mining alt coins like eth, and convert earnings to bitcoin to get an estimate. Pretty sure more is made from mining AND it's guaranteed (if in a eth pool, or solo if you have enough juice) versus you may run cards 6 months, a year, 2 years, and never find puzzle key(s).

Ethereum mining on the T4 can make me about $75 a month, however this drastically reduces the speed of Bitcrack and other tools to half, sometimes even to 1/3rd, so I wouldn't particularly recommend mining at the same time.

Could you tell me how are you searching 21 million wallets and at that speed I’m using command and can only search 230 address at a time. Thanks Lostrelic

Definitely not with Bitcrack (it's not capable of those speeds), maybe he's running hashcat's SHA256 mode against millions of public keys? 450Mhash/s sounds doable for SHA256 with high-end cards.

Thanks for responding but when I search for keys 1 or 230 addresses at a time it doesn’t affect my speed is there a way to search for more than 230 addresses that maxes out the character limit on command prompt. Thanks lostrelic

Hey guys,
Can i hire anyone for $80 to help me with getting this easily loaded onto Vast.ai instances
Basically i want to try two things:
1) load a list of passwords and check it against another file containing addresses
2) Generate random public wallets and check them against a database for a match (which im guessing is what bitcrack does)?

Am i correct that since this uses CUDA it processes up to 1 million or more passwords per second?
I'm only trying this with abandoned wallets. I'm in serious debt in about a month and this is my last ditch effort (i know the odds)

Thank you

You don't have any chance actually. I'm trying this with 21 million wallets & 450million keys per seconds. Nothing found for more than 2 months. (Everyday 15 minutes of testing). I'm not trying for dump someone's wallet, i just want to see it's possible to crack a SHA256 with Bruteforce.

Could you tell me how are you searching 21 million wallets and at that speed I’m using command and can only search 230 address at a time. Thanks Lostrelic

All you guys with RTX 2000 cards, I'd appreciate if you posted benchmarks of Bitcrack3000 on them too, because as I've already said, it doesn't seem to like Tesla GPUs Sad

Meanwhile we still don't know if this even works on Ampere GPUs, that would be embarrassing indeed.

I know now reward halved to 6.25 BTC
yes it 10x from puzzle #64

but it is need to do only solo mine alone and get all reward (and luckly)
How much to get from pool mining for 30 day with RTX 3000 series or Tesla v100 ?

Bitcoin GPU Mining is over, but you can mine ETH and exchange it to BTC

How many you can get, please have a look at https://www.whattomine.com/

puzzle #64 rewards = 0.6 bitcoin

RTX 3070 or Tesla V100 is powerful if running 30 days 7x24 hour works

Also, your above times seem off, what is time start to finish?

Last thing, why did you run bitcrack and sp's mod in compression mode but put VS with bitcrack searching for both compressed and uncompressed? That obviously impacts speed and time to find key.

example you want to solve puzzle #96 addresss 15ANYzzCp5BFHcCnVFzXqyibpzgPLWaD8b

puzzle #96 is high 2**96 (2 Exponent 96) 2^96 = 79228162514264337593543950336
this rank is number between 2^95 - 2^96 = 39614081257132168796771975168 - 79228162514264337593543950336

that mean key is 1 of 39614081257132168796771975168 number between 39614081257132168796771975168 to 79228162514264337593543950336

bitcrack using number in HEX
when you config use number in hex format not number decimal

convert number decimal to hex
https://www.rapidtables.com/convert/number/decimal-to-hex.html
39614081257132168796771975168 = 800000000000000000000000
79228162514264337593543950336-1 = FFFFFFFFFFFFFFFFFFFFFFFF

you need to start from 39614081257132168796771975168 = 800000000000000000000000
don't start from 000001

Thank you very mutch, i never will under stand without this.
But i dont understand the -1 from 79228162514264337593543950336-1
if i convert 79228162514264337593543950336 from decimal to hex it says 1000000000000000000000000???

for the range i must set the command then like this correct? --keyspace 800000000000000000000000:FFFFFFFFFFFFFFFFFFFFFFFF

example you want to solve puzzle #96 addresss 15ANYzzCp5BFHcCnVFzXqyibpzgPLWaD8b

With bitcrack sp-mod I believe it is bether to search for more puzzles at the same time because it doesn't slow down the search. You can add 64 puzzle adresses increase the range and the search speed will increase. Well, not really increasing, but you are increasing your probability 64 times to find a solution.

how does sp-mod works? i mean how can i set the keyspace for each?

Why don't you fork the existing repository? Then it will be easier to see what you have changed.

My repo is forked from https://github.com/BoGnY/BitCrack/

BoGnY's the one who added random mode and updated the CUDA VS props to 10.2. He also added the memory vectorization stuff (I think that's where my speed boost is coming from).

All the commits between 786ea361 and c3121cf6 are his changes https://github.com/ZenulAbidin/BitCrack-3000/compare/786ea361..c3121cf6 , everything after c3121cf6 are my changes.

So it looks like that BitCrack hates any kind of cicc optimization and will immediately throw a misaligned address even on optimization level 1.

Ptxas optimization still works though, and setting it to the default level 3 triples the speed on my T4. Now before anyone gets excited about this, the speed still sucks compared to older cards (only 60MKeys/s now). Wink

Meanwhile I have pushed the updates to https://github.com/ZenulAbidin/BitCrack-3000

Go get 'em boys.

yes, for 15ANY address, you have the correct 96 bit range. All addresses were funded by the creator of the challenge.

and how can i set the range right? what means the 295?? must i write --keyspace 800000000000000000000000:ffffffffffffffffffffffff ? start with ..0000001 ?

example you want to solve puzzle #96 addresss 15ANYzzCp5BFHcCnVFzXqyibpzgPLWaD8b

puzzle #96 is high 2**96 (2 Exponent 96) 2^96 = 79228162514264337593543950336
this rank is number between 2^95 - 2^96 = 39614081257132168796771975168 - 79228162514264337593543950336

that mean key is 1 of 39614081257132168796771975168 number between 39614081257132168796771975168 to 79228162514264337593543950336

bitcrack using number in HEX
when you config use number in hex format not number decimal

convert number decimal to hex
https://www.rapidtables.com/convert/number/decimal-to-hex.html
39614081257132168796771975168 = 800000000000000000000000
79228162514264337593543950336-1 = FFFFFFFFFFFFFFFFFFFFFFFF

you need to start from 39614081257132168796771975168 = 800000000000000000000000
don't start from 000001

Why this happens when i open sln file of @NotATether source

That's how it's always been with the .SLN files of Bitcrack, I guess if they are loaded when I merge them to git then they will be loaded by default, but I don't particularly recommend this because VS builds all the loaded projects together, so an error in one project will abort the entire build process.

puzzle is bitcoin address you need to crack bitcoin address by fine private key
if you got private key you can access to bitcoin and transfer bitcoin to you own as rewards

hint for puzzle is key range of bitcoin tell you know that bitcoin have private key on what range you can find it on range

puzzle 1 to 63 is solve already next will be puzzle 64 or any puzzle not yet solve

choose puzzle you want to solve and try to finish as you want
most select puzzle 64 for now because puzzle 64 is 64 bit is low range it is low bits to easy for crack if high range is very hard to crack it

this puzzle same in this forum
https://privatekeys.pw/puzzles/bitcoin-puzzle-tx
https://bitcointalksearch.org/topic/bitcoin-challenge-transaction-1000-btc-total-bounty-to-solvers-updated-5218972
https://bitcointalksearch.org/topic/bitcoin-puzzle-transaction-32-btc-prize-to-who-solves-it-1306983

can someone explain how the puzzle works i mean how i must set the range?
for example: 15ANYzzCp5BFHcCnVFzXqyibpzgPLWaD8b
there is written: 295...296 800000000000000000000000...ffffffffffffffffffffffff

and the adresses is this from someone made the puzzle or from some unknow people?
