1  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: December 05, 2021, 11:25:13 PM
I saw Large Bitcoin Collider project and I saw that they found their 1st address after "only" 7400 billions of keys

Quote
The pool found a private key to f92044c7924e5525c61207972c253c9fc9f086f7 (1PiFuqGpG8yGM5v6rNHWS3TjsG6awgEGA1) as 0x6bd3b27c591. At the time of the find, there were 0 BTC on that address. This is #43 of the puzzle transaction.
I think they found 0 BTC because in the moment of collision the balance was already spent

6bd3b27c591 = 7409811047825

So is this project real or fake?? I thought maybe they calculated the addresses they will find in the future and then they sent money to them and then show those addresses like "trophies"

I think we are not scanning 2^256 but 2^160... There are 2^160 of addresses not 2^256

I took range like this
24 random 0 to F + 40 x 0
like this
e3b2c44298fc1c149afbf4c80000000000000000000000000000000000000000

I use sp-hash 5

I have 2 PCs and I have around 23.800.000 targets...

Have Asus 1060  and Zotac 1060 both NVIDIA

I have a speed of 100Milions keys per second on each... so 200MKeys/s against 23.800.000 addresses
I am doing this for like few weeks.. not 24/7 but 24/6 Smiley and I scanned

371,524,951,867,394 addresses

So what do you think - should I stop doing this???

And also one more thing.


When I look at this picture I see that this one value for x and y of R
has millions and billions different pairs of x and y of Q and P
I mean just change the slope of the line

@mausuv

I am searching for this too... It looks to me that if | public key = private key * G point | then some parts of the whole process is the same for all keys... It does not need to be calculated again... Also what I understood is I have 2 points P and Q and I am searching for  x and y of R... So what does generator points have to do with all process... And how do I get values of P and Q if I know the private key and that private key has a value "0x2"... Somebody could explain which variable means what?

6  Bitcoin / Development & Technical Discussion / Re: Generating bitcoin public key - question for a school project :) on: November 16, 2021, 03:42:25 PM
Can you tell me in your formulas what each element means... Also, can you tell me where is the part where the private key value  is added to equation Smiley

xr = s2 - xp - xq
yr = -yp + s(xp - xr)

I saw this so my question is - if I want to calculate only X value and get compressed key then I do not need to calculate other part
7  Bitcoin / Development & Technical Discussion / Generating bitcoin public key - question for a school project :) on: November 16, 2021, 12:51:41 AM
So yes I did choose a topic for my college final exam. I will make a presentation about bitcoin and everything...

I know how technically the bitcoin address is generated but I just do not know how to generate a public key but just calculating with a "calculator"

So I tried to do it by myself...

I know that Sha256 1st private key 0000000...001 will give this public  key 0479BE667EF9DCBBAC55A06295CE870B07029BFCDB2DCE28D959F2815B16F81798483ADA7726A3C 4655DA4FBFC0E1108A8FD17B448A68554199C47D08FFB10D4B8
because this is the start point of G point (04 is the prefix then 64 letters are X and next 64 letters are Y)... So I understand this...

But in the case where I choose the second private key 0000000...002 I tried to do this...

I know for this multiplication so in my case number 2 is "10" binary so my multiplication will look like this

0 1*G

1 2*G

0 4*G

0 8*G

0 16*G

0 32*G

0 64*G

0 128*G

...

So I tried to do this manually Smiley (I know PHP GMP functions)

Hex to decimal "79BE667EF9DCBBAC55A06295CE870B07029BFCDB2DCE28D959F2815B16F81798483ADA7726A3C46 55DA4FBFC0E1108A8FD17B448A68554199C47D08FFB10D4B8" = 6376237641841063197511976314280597438149211753541909917794154839912978489307502 705320406087313832827571435203289817719151821525032884964596839752540411064

Then I did 2G and I got
1275247528368212639502395262856119487629842350708381983558830967982595697861500 5410640812174627665655142870406579635438303643050065769929193679505080822128

Now dec to hex
F37CCCFDF3B97758AB40C52B9D0E160E0537F9B65B9C51B2B3E502B62DF02F309075B4EE4D4788C ABB49F7F81C221151FA2F68914D0AA833388FA11FF621A970
And I should add 04 on the beginning ... but I found that this is not a public key of private key 2
Correct public key is
04C6047F9441ED7D6D3045406E95C07CD85C778E4B8CEF3CA7ABAC09B95C709EE51AE168FEA63DC 339A3C58419466CEAEEF7F632653266D0E1236431A950CFE52A

so what I did wrong?

Sta mislite o tome sto planiraju da daju 1000 coina za 1 coin... Da li ce stvarno biti vise prostora za rast cene

Takodje pogledajte i ovo. Majner iz Beograda zaradio 1094$ za mesec dana

I invested one part in this coin... I think the price can go much higher because they have a physical product and I saw that people are waiting for their miners for like 5-6 months so a lot of people want to be part of this coin...

The thing I do not like is that "Redenomination" story where they want to give 1000 new coins for 1 old... so Supply will be 111 billion of coins - now I have 100 coins worth of 50$ and after that, I will have like 100.000 coins worth 5 cents - I do not now Smiley

In cmd it says

-infile  Set file with pubkey for searching in uncompressed/compressed  format (search sequential)

So it will get 1st key and then search it until it finds it and it will search for 2nd 3rd 4th... to the end of list
11  Bitcoin / Development & Technical Discussion / Re: BSGS solver for cuda on: November 11, 2021, 07:20:53 PM
Can you put the option to search multiple pubic keys... To search for example 100 keys at once? Not 1by1


You have no idea what you are talking about, what you are doing and what is the algorithm.

I saw that program search only 1 public key - what did I ask wrong?

13  Bitcoin / Development & Technical Discussion / Re: BSGS solver for cuda on: November 10, 2021, 05:12:23 PM
I did my research again. With cuBitCrack I search around 200Mkeys/s with 2x Nvidia 1060
I have a text file with 23milion addresses

The range of my search will be  0 to ffffffffffffffffffffffffffffffffffffffff - 2^160

With this software, first I manually found around 20 (just 20 not 20 million) public keys then started to scan and I got around 700Mkeys/s which is good... But I realized that my searching range is now 0 to 2^256 and also I am searching only 20 keys...

So why is this software better than cuBitCrack?
14  Bitcoin / Development & Technical Discussion / Re: BSGS solver for cuda on: November 10, 2021, 01:53:20 PM
I did my research... This is a very good tool <3
15  Bitcoin / Development & Technical Discussion / Re: BSGS solver for cuda on: November 10, 2021, 12:49:52 PM
So I need to know Public Key from the address to search the private key???
How can I find a Public key from the address - for example 1E4oDjEoBPXLS8vSYZ5dgjQEf4PZ4FLRhY

How can I select multiple GPUs???
I am using this fork and I have 2x1060 6GB

I downloaded your link. Thank you
18  Bitcoin / Project Development / Re: List of all Bitcoin addresses with a balance on: November 04, 2021, 08:09:06 PM
At the moment the website is not working. Can you maybe split files so 1 file will contain only addresses that start with "1" for example "1jFkHrG18Hc6ae9jTxXyJxqHyzmUjNdyQ"?

Also can I donate via Paypal?

Can you upload this big files for example to "Wetransfer" or "Torrent"... I Have 1 Gb/s downloading 800MB 45 minutes
20  Economy / Invites & Accounts / Selling 326 TH account - Hashflare on: May 21, 2018, 09:53:29 PM
How much money I can get if I offer the 326TH contract on sale. The contract will last until mid of December.

This is the proof that I own this account
