This address uncompressed
1HZwkjkeaoZfTSaJxDw6aKkxp45agDiEzN

Belongs to empty string SHA-256 hash used as private key :

e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

Chop chop fellow hunters, dive into the world of keys and hashes. Note the address has 0.00313110 BTC and not 0.0016. Good luck with my clues.😉

All keys are in 255 Bit , 256 bit is a mirrow
So are you suggesting that all the keys starting with 8, 9, a, b, c, d, e and f are all in 255 bit range and also all keys starting with 1, 2, 3, 4, 5, 6, and 7 are as well in 255 bit?



Whenever you see a private key starting with 8, 9, a, b, c, d, e, f, you can tell it's 255+ bit, even most of the keys starting with 7 are in 255+ bit. This is why I use hexadecimal over decimal, as it is easier to recognize patterns, but if you work with decimals, you can't even tell which number is greater than the other, but in hex you can count 2 by 2 to quickly determine the size and the exact range.
1283  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: July 13, 2023, 02:09:29 PM

What if we could divide by bits the range all the way to 1 bit? All keys are the modular inverse of the first key start point.

Thanks to Quite the Contrary for teaching me how to do this https://youtu.be/Vlqy1zB-QkE  ecdsa secp256k1 algorithm explained.
 Shocked
How do you propose we divide by bits down to 1? And who taught you what exactly, the youtube you meant?


As I see it, it's just 7 divided in half

He just subtracted 7 from N and divided the result by 2, and as I see it, it's just 15 divided in half, because dividing 7 in half would give you 3.5 where you could see 3 as the first character and that .5 as a huge number, here is the example :
3fffffffffffffffffffffffffffffffaeabb739abd2280eeff497a3340d9052

As you see, the .5 which is a fraction has turned to something different, this is the beauty of big numbers combined with elliptic curves.😉

Guys I'm still waiting for my answer, since I revealed the exact range of my public key, it is no use if anyone can tell me the range.

03cefd304a9a8da40666e97b2d9650e31a71a9a9fcd29a24724d31a2fabbc8ea0e

I just want you to drop the second digit from my private key having just my public key above.



Mathematical problems are solved in decimals, if you work in hex or binary you will only confuse your research, once you get results you apply the conversions, if you work in hex or binary you overlook important details such as the sum of the Y coordinates of a mirrored pubkey (negative) Y+(-Y) always equals

or why? these pk share the same X coordinates.

I'm a bit lost after reading your reply, what is this exactly
7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a4

And this one?
7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b209d

Why did you post 2 random keys with only 7 keys difference between them?
I'm asking this because my private key has 7 in it, can you just tell me where did you get the 2 private keys above?



To the rest of you guys, don't fight and argue, there are hundreds if bitcoins waiting for you to collect, you can show your skills by collecting them.😉
1285  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: July 12, 2023, 10:41:55 AM
You can find out the range from the public key.


This is serious stuff, you probably didn't realize what you said... HOW ON EARTH YOU FIGURE THE RANGE FROM PUBLIC KEY?




To believe in a word or not is your right.

PS Everything will go to society together when the work is completed.
Best regards.
If I tell you a certain key exist in a certain range, and if you know the first character of the private key, you might be able to get close to validating the authenticity of my claim, but without that information, there is no other way than brute forcing all the possible ranges one by one, but it would be great to learn something new before you decide to bring all the societies into the action, so share and care, right?😉

Such backdoors exist in firmware, not necessarily in hardware, though there is only rumors, that's because these backdoors are being used for big targets like using them to spy on nations military bases, and sensitive locations where secrets exist, they would never use it on populations at random.

Windows xp is one of the safest operating systems to use in order to avoid getting backdoored!😅
1287  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: July 12, 2023, 08:27:55 AM
Ok, lets test your script without you revealing it to the public, just drop the first 2 characters on the left for this public key's private key :

03cefd304a9a8da40666e97b2d9650e31a71a9a9fcd29a24724d31a2fabbc8ea0e

Do you need the exact range or not? It has 32 characters and it starts with F, just drop the second character and give me the public key for it to verify, that could help a lot for others to believe you.

I did not understand your proposal very well regarding the range of your pk

but for example if you eliminate the first 2 digits of your pk in decimal and generate another pubkey you will possibly get a pubkey that starts (although I recommend explaining the range better):

1= 03941029...
2=02caf96e4..

After I know what your pubkey is, I get the rest of the digits.

without the need to generate millions of keys.
I was very clear, I gave you my public key, and my private key has 32 hex characters starting with F, I just want you to drop the second character with your first try since there are only 16 possible answers, if your script works, you should be able to drop the second char from my private key.

Only hex, I don't work with decimal or binary.

Do you think another person have access to it?
No.
How many bitcoins did you have?
How did you lose your device?
Did someone take/stole it?
Was the wallet password protected?
Do you have the address or public key? (Lol my obsession with public keys.)

Is there any official thread on brave browser here? Or someone who knows stuff about it? Every time I switch between open apps, the open brave tabs refresh, it looks like I am refreshing a page 200 times a day, is there any reason for that?

I don't know why but this Timelord guy is present every where when someone mentions masterbution, and when I call him out as a professional masturbator he reacts as if I have offended him!

Anyways, have you guys ever tried to use your left hand? Speaking from experience, if you do it once with the left and once with the right hand you will be amazed by the result, isn't that right Timey lordy? 🤣🤣
1292  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: July 12, 2023, 12:47:03 AM
It all lies in computing power, currently I can reduce the range of puzzle #130 to the equivalent of looking for the public key of puzzle #103 without slowing down the search (my resources aren't useful for looking for a public key in range 103 anyway), I could reduce more but I do not have the necessary resources for it and the search becomes slow, therefore it is my "acceptable" range. It doesn't seem unreasonable to me that more puzzles will continue to be found this year by comparing what I can do with basic resources with others who have many .

in short, a puzzle for rich people
Well, if you can really reduce the range down to 103 bits, there are already a few hunters with decent rigs willing to help you out and then you could use an escrow to split the prize, you could also divide the 103 bit range into 100 small ranges and search each one per day, after 100 days or even less, you will find the key, but the question is, are you really sure you can lower the range to 103 or even lower? What if the key you are looking for is not there?

You need to provide a reasonable solution to prove that the target is in the said range.

Good luck though, I'm off this puzzle till I see the private keys for #120 and especially #125, I might work on other puzzles here and there, but won't engage in sharing my findings and talk about possible solutions, as it seems we could spend more than 120 days 24/7 just to have nothing at the end, and I don't mean money, who ever solved it they deserve it and I hope the best for them, but not being able to have the answer ( private key ) of the puzzle, even an empty key, is a deal breaker.
1293  Bitcoin / Development & Technical Discussion / Re: Points where x=y on secp256k1 on: July 11, 2023, 09:41:32 PM

so x^2=x^3+7

How exactly x^2 is = x^3+7? Is that a typo? Also have you ever seen x=y in secp256k1?
A few months ago as I was playing around with xs and ys, I remember to see something like x=y, but since I had no  clue what that could really mean, I just ignored it.

Main question, what would be the result of finding such points on secp256k1?
1294  Bitcoin / Development & Technical Discussion / Re: Possible hardware backdoors on: July 11, 2023, 09:32:35 PM
Do you have any factual evidence to back your claim? If this is speculation and imagination/science fiction then no need to think about it, show some real world proof other than youtube video.
1295  Bitcoin / Development & Technical Discussion / Re: BRC721Auto - Fully Autonomous Generative Art Protocol on Bitcoin on: July 11, 2023, 09:27:30 PM
By art you mean monkeys and apes? And what kind of art are we exactly talking about? Something like AI generated 3D images where you can type anything and have it rendered by powerful GPUs? I really don't see any reason to use bitcoin blockchain for anything other than transferring bitcoins.
1296  Bitcoin / Bitcoin Discussion / Re: PUZZLE : The Lost Bitcoin Treasure on: July 11, 2023, 06:43:56 PM
Legend has it that a renowned Bitcoin trader, Satoshi the Magnificent, buried a treasure trove of Bitcoins in a secret location. After years of searching, a cryptic clue has been discovered, leading to the hidden fortune.


Solve the puzzle to claim the prize!

Clue:


Within the digital realm, a code conceals,
To solve the mystery, your mind it appeals.
A block of transactions, an enigma held,
Seek the key to unlock, secrets to unveil.

Start with a number, the Genesis it reflects,
A marker of birth, where history connects.
Multiply by a prime, a factor divine,
A clue to unravel, the path you'll align.

Next, find the sum of digits, a challenge awaits,
Persistence is key, as complexity abates.
Reverse the result, a mirror's reflection,
Digits rearranged, a cryptographic direction.

Now take the ASCII, the text shall reveal,
Letters hold power, a message concealed.
Decipher the words, unlock the cipher,
A key to the treasure, your victory will inspire.


Wow, you should be more specific about this treasure, what is the motive for hiding it?  Where is the address or public key?
Besides, we already have a puzzle and we know the addresses, words alone mean nothing, show me the coins.😉
1297  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~1000 BTC total bounty to solvers! ==UPDATED== on: July 11, 2023, 03:02:28 PM
I'm finished my own brute forcer that run all calculations purely on GPU (CUDA), I started some tests and looks ok but the challenge is to be fast as possible and actually it only can be achieved by using multi gpus.

next step is prepare it for multi gpus focusing on #66

if anyone with dozens of gpus woud like to TRY it, we can do a fair partnership to share the money.  Smiley
There are a few of such programs, first you need to link to your github page, make it open source so everyone can verify the safety, and in time if there is a need for improvement, other devs will improve it. 😉

What do yo think about creator step 5 bit range pubkey?
Faster search and get private key maybe he hint to you for solve non pubkey puzzle.

Why would there be any hints? This is not a game, it's a measurement for time taken to solve different keys in certain ranges.
If there was a shortcut to find a private key with only having an address, bitcoin wouldn't be here today.
1299  Bitcoin / Bitcoin Technical Support / Re: Private key of BTC wallet on: July 11, 2023, 01:38:25 PM
we are not talking about how much BTC are in address, but how many transactions are out. then we can talk. If you do not understand -> do not issue "post"
What do you mean by "but how many transactions are out"? Are you talking about inputs and outputs on the address, nevertheless it has no connection with op's problems, neither can it help them find the missing characters of their private key. If i may ask, how do you intend to use what you are requesting to get the missing characters?
Obviously he wants to check if the public key is known, if you have the public key and a few chars of private key, it can greatly help you finding the private key, but success is not guaranteed.
