Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Just an update that tripped me up, all the puzzles start with a 1 binary.
So every puzzle has half the possible combinations.
Like puzzle two only has the combinations 11 and 10 i thought it could of also had 01 and 00.
Nice little boost

Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Based on our previous discussions, does this mean the key is likely between D1xxx and EFxxx? Or could it still be in lowercase?
I also had an idea for filtering:
Skip keys with 4 or more repeating characters, like xxxx, aaaa, bbbb.
Skip keys with 4 or more consecutive sequences, like abcd, 1234.
Skip keys with 4 or more descending sequences, like 4321, 5432.
Skip keys with 3 or more repeating patterns, such as ababab, acacac, 121212, abcabcabc.
Any ideas on how to implement these filters in BitCrack? It might help reduce a lot of unnecessary checks 😅.

No, this Vanity Search does not prove anything, it can be 8 , it can be f
I'm also looking for the same thing, as the so called random is not perfect and have noticed some pattens in other keys.
I can filter out about 91% bs attempts but still have a 90% chance of cracking it, this would still take 256 gpus 4-5 months, so its no easy task and would probably have to team up with someone. I guess you can hire 256 GPU but that would get pricy.
Before anyone says I'm talking bs, my filtering would of worked on about 93% of previous keys. So I have no reason to believe it would not work on either 68 or 69 or 71, one of them worst case I would say.
68 27,000,000,000,000,000,00 With filtering
68 295,147,905,179,352,825,856 Total combinations
But as Wandering kindly pointed out you probably only have to check 50% of your possible guesses till you find the answer. So
68 13,600,000,000,000,000,00 With filtering + like 50% checked around about.

The $1000 also included the local connection fee and of $2 a day and the 10 rigs had CPUs, ram, SSDs, fans, psu not 100% efficient and other house power usage so probably more like $800. But yes our power is a rip. But if you wanted to set up 256 GPUs like you say you would need all these things.
You also have the possibility that someone will beat you to Key.
And your numbers are off as you could check like 80-90% of the keys before you get the right one and in that case its like 5 years lol
6800000000(hash) * 60(secs) * 60(mins) * 24(hours) * 256(gpus) * 2000(days) = 3.0e+20
3.0e+20 with no down time, no blowen up gpus, no issues, no cleaning.
2.9e+20 all possible keys checked
After 5 years odds are half them GPUS be up in smoke too Grin

You do not have to tell me about what goes in to mining. At the height of it, I had more than triple the amount of cards you had. I never had a rig with less than 13 GPUs on it, so mine was probably a lot cheaper to set up as far as mobo, cpu, RAM, etc.
As for you telling me my numbers are way off, I will not play shoulda coulda woulda word salads with you.
I am basing my numbers off of the average. The last 2 keys found were at 52% and 57%, the average says around 50%, but I even went with the higher of the 2 previous keys found.
Why won't I play your word games lol, because the key could be found at .5%, 1%, 10%, etc. which would make it way cheaper.
So let's stick to factual numbers based off of something or we could play forum tag all day.
If I am renting, I do not care if the GPUs go up in smoke. But if they were mine, they wouldn't, or very few might. I have cards that I've owned over 6 years that still work. You actually have to take care of them, clean them, and keep them cool. I only lost one card, an AMD, because I bricked it trying to flash the BIOS. That was it. And that is also why I went all in on Team Green and got away from Red.

Bram = Someone who is part of a team, I still have doubts about him being a team member. Because he may have requested these signing events from his team. Also, this team has made serious investments for this business.
He does not have any software that reaches more speed.
He does not have any software that reaches more speed.
So you doubt someone, even after you threw fits because someone doubted you lol.
There are several versions out there that get more BK/s than some public version you are using.
I have one, it gets 7.1 BK/s, one of the public pool has one that is equal or better than mine (sign up and run a range, it's easy as that to verify for yourself). So I have no doubts there are faster versions out there, including Bram's.
You said 500 days its more like 1000-1100 days (on a average) with some down time. Like 3 years but you have to plan for worst case when working out probability and it could be 99% or like 6 years, you sound B hurt.
GPU 24/7 have an expiry date, maybe look into servers and hardware update life.
Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
This is pretty much the problem I'm having.
I can narrow the 68 puzzle down from.
295,147,905,179,352,825,856 Combinations to
402,120,015,509,709,217 Combinations
With a estimated 35-40% chance one will be right.
but even with 3 zeros removed its still requires a huge amount of compute.
I just assumed with only 0.15% of all possibilities needed it would take a regular 3090 like one week, but even with 8 3090s it would still take months.
I have no idea how people plan to pool mine this thing, will probably cost more in power than it is worth. unless you have a asic + low cost power and custom code.
if 8 3090s can check say 30billion keys a sec total (its not just a single 256 hash so prob cant even do that). it would take me about 140 days to check my guess.
so if you had 8000 3090 you could check every combo in 140 days estimate. From memory when I had my mining farm 60 Gpus were about $1000 a month in power but only using 100watts each, so your looking at about $200,000 a month in power or 1.2m to check every combo and also the loss in gpu value as tech devalues. Lets say 10% loss in value, or 800gpus, so like another 800k probably.
So for $2 million dollars you can crack this thing

Your numbers are way off. Even in your power costs for running 60 GPUs at 100w each, unless you live in a place where power costs are extremely high, which could be. At 15 cents per (kWh) costs, you'd be looking at $684 a month. For a $1000 a month, you'd be looking at 23.1 cents per kWh. That's pretty high IMO.
If you base the average solution time (the keys checked to actually find the solution) off of 67's, and you had to rent every GPU through a public supplier, you'd be looking at about $686,000 to solve 68. A lot less than the $2,000,000 you spoke of. If you owned your own GPUs, and had costs of 15 cents per kWh, you'd be looking at costs of around $206,000. These numbers are based off of using 256 x RTX 4090s, at 6.8 BK/s, which there are software versions out there that get over 7 BK/s, so I went a little lower.
2^67 * 57% / (6800000000 * 60 * 60 * 24 * 256) = 559 days
Unless, my numbers are way off, or I am not understanding what you are saying, both could be true lol.

Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Ok few questions before I get a GPU, because I will have around 200 trillion combinations maybe more.
Is the 4090 or 5090 way faster or not worth the $$ or is the 3090 just the best bang for your buck does it have to be Nvidia as AMD have good price to performance.
Converting into a Hexadecimal without Ox sounds easy enough. Hopefully python can output 100 trillion numbers without issues.
Could you give me a basic run though and how to set up and use keyhunt-cuda on a premade hexadecimal file (using a subprocess). Would it be txt file or a py file or a json file.
Also I take it this computation can be done offline once setup?
Cheers
With that many combinations it would be faster to write your own software since you would have to start and close the program every time.
What are the combinations are they ranges like 80000:fffff or are they 1 hexadecimal like d2c55?
if they are ranges then you would want to customize keyhunt-cuda so that each thread is of the gpu is searching a custom range.
if they are 1 hex number then a python script would be enough but it would take a long time and if you wanted to do it faster then you would want to write it in C or C++.
I don't know about the specific speeds for the 5090 but in this topic there should be 4090 speeds if I remember correctly it's around 4 to 6 billion keys a second.
Just a big list of hex/binary/decimal numbers no ranges or anything like that, I cant go into anymore detail or will be out of pocket 6.7btc
A python script would probably be fine but then that is CPU only then?. But that might work. Has anyone made a basic python script to check keys from a script.I guess GPU is a non issue, ill just get basic code working first.
I have done quite a bit of coding, but nothing on the cryptography side. I take it it would only be a few 100 lines of code?
Is it just like take 256bit private key guess, then hash it to the wallet address and check that matches the wallet address?
Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Hey Puzzlers
What would be the best offline way to test a big list of either Decimal or Binary possibilities I have.
Just CPU testing, I could buy a GPU if its like 100x faster than CPU.
Happy to give the 1-3 people 0.1btc that help me when I solve puzzle 69. (If that's allowed on this forum)
Note offline solving only, no pools or online, happy to download any requirements first. - This pc will not be connected to the internet once ready to solve the problem.

For cpu you want to use keyhunt or keyhunt-cuda. here's the links https://github.com/WanderingPhilosopher/KeyHuntCudaClient https://github.com/albertobsd/keyhunt
You can also find pre compiled ones for keyhunt on github.
cpu averages about 3.5 million keys a second per thread if using above software or I believe according to ktimesg 10 million keys a second per thread with custom software.
Gpu's are way faster a 3080 does about 2200MK/s or 2.2 billion keys a second.
Best way to test a big list is to write a python script to read the doc and import the possibilities into a list then in a loop convert the decimal or binary into hexadecimal get rid of the 0x in the front and run keyhunt or kehunt-cuda in that range using a subprocess.
