i wonder about privatekeys website

when i check for any addresss , i get the same addresses from different networks bitcoin gold , bitcoin cash ,,,etc
that has the same private key ?

and i wonder how is that possible without knowing the private key from the beginning ??

lets say for puzzle 66
13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so

Addresses with the same Private Key :

and i wonder how is that possible without knowing the private key from the beginning ??

All those address can be derived from the RMD hash of the address, example:

Address 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so decoded in to Hexadecimal is:

0020d45a6a762535700ce9e0b216e31994335db8a5ee6612b2

But first byte for btc address is alway 00 and last 4 bytes are te checksum: ee6612b2

So the Real hash160 of the address 20d45a6a762535700ce9e0b216e31994335db8a5

Example with Dogecoin is almost the same, address D88gYxMEoumtZSJAC9mwa2EWfm6g3uocon

Decodes is 1e20d45a6a762535700ce9e0b216e31994335db8a50d861875

1e is the prefix for Doge, the checksum are the last 4 bytes: 0d861875

So the Real hash160 of the address 20d45a6a762535700ce9e0b216e31994335db8a5

So for almost all altcoin you only need the original rmd160 hash check the next image:

Never use such websites to search for your address/private keys, they will log and then will take any coin deposited to your address in the future.
Whoever holds the private key for puzzle 66, can spend all those garbage coins as well. You can even fork bitcoin and send millions of useless and worthless coins to that address.

Anyways, as long as a crypto coin is using secp256k1 curve to generate their private keys, all keys can spend from other coins which are using the same curve.

Ps, welcome Dr.😉

I think the puzzle creator should reveal the public keys for all the keys bigger than 120bit except 124, 134, 144, 154, this will make the challenge reflect the true strength of bitcoin security.

[GR Sasa]

I think the puzzle creator should reveal the public keys for all the keys bigger than 120bit except 124, 134, 144, 154, this will make the challenge reflect the true strength of bitcoin security.

No i dont support that.

I don't support that, because if satoshi reveals public key for the lowered bits, the same guy who solved #120 #125, will also solve them and take the money for himself and leave us nothing but a air to eat.

And why except 124, 134, 144, 154?

[digaran]

Oh look, I'm back here again with useless stuff,

Code:

from sympy import mod_inverse

N = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141

def ters(scalar, target):
    k = mod_inverse(2, N)
    scalar_bin = bin(scalar)[2:]
    for i in range(len(scalar_bin)):
        if scalar_bin[i] == '0':
            result = (target * k) % N
        else:
            result = ((target * k) % N + N - 57896044618658097711785492504343953926418782139537452191302581570759080747169 ) % N
        target = result
    return result

target1 = 1361129467683753853853498429727072845824
target2 = 961437616415839130310402076835011931977

print("Target results:")
for x in range(1, 256):
    result1 = ters(x, target1)
    print(f"T1: {result1:x}")
for x in range(1, 256):
    result2 = ters(x, target2)
    print(f"T2: {result2:x}")
for x in range(1, 256):
    result1 = ters(x, target1)
    result2 = ters(x, target2)
    subtraction = (result1  - result2) % N
    print(f"S: {subtraction:x}")

Lets imagine target 2 T2, is puzzle 130, target 1 T1 is obviously a known k, after running the script look at T2 results, then change N+N - "this value needs to be tweaked", and then look at the results, T2 and S results, change the range from 1, 256 to whatever you want, add 1 to target 1 then run, try subtracting what ever you have been subtracting from the real 130 so far, from T2 and put both of them on target 1 and 2, try having the greater key on t1 and smaller on t2 and vice versa, try and test everything you can think of, you can also try several test keys as if they are puzzle 130, try different keys, odd, even, prime, composite.

When you are done, I will give you a script to do this with points, or you could convert it yourself if you know python.😉

I may be lacking some understanding on this matter—can anyone clarify? Let's hypothetically say someone has the ‘luck’ or the means to resolve these puzzles and acquire the BTC. Is this presumed to be legal, and if so, to what extent? Suppose the fortunate individual or team decides to convert it to fiat. How feasible is this, practically speaking? Is selling the BTC to platforms like Coinbase and then transferring to your bank a viable option? I don't think we can realistically expect that BOA, Wells Fargo, etc will overlook a client suddenly receiving hundreds of thousands, or even millions, of dollars... And there’s the potential of platforms like Coinbase restricting high-value transfers. This might work for smaller amounts, but some of these addresses are worth hundreds of thousands of dollars each.

Returning to the legal bit, how does one justify these funds? Informing the IRS that it was a giveaway from a random forum user is bound to raise eyebrows, right?

I'm not intending to discourage anyone; I'm genuinely curious about how such a substantial BTC to fiat exchange would occur without legal repercussions...

I'll keep it short and clear.

"Your Private Key, Your Coins" So if you got the chance to get any private key of any address that has funds, you are it's owner.

No. This may be true for keeping the coins for your grandkids. But people usually want to use them to buy real stuff, like houses or cars. Saying “my keys, my coins” when someone asks where your $2 million is from? That just sounds silly.

Also, this idea that having a key means ownership has its limits. If I steal someone's key, does that make it legally mine? Definitely not. This argument doesn’t hold up in the real world; it only proves a cryptographic relationship and virtual proof of access.

[digaran]

Wait a minute, allow me to analyze this saying: "Your Private Key, Your Coins" So if you got the chance to get any private key of any address that has funds, you are it's owner." Unquote.

Are we talking about this particular puzzle addresses or in general? If it's in general, then one might say : " if you get a chance to find a woman alone, you can have her anyway you like"  what if that woman is your wife, sister, daughter  or mother?

So no, if you find any keys with funds, unless it's a puzzle key, you should not touch them because they're not yours, so hands off the merch.😉

When you find a puzzle key, you better erase yourself from online world and gradually cash out without using any CEX, if you were "lucky" ( yeah, right ) and by chance you found it, better to explain how you found it and be sure to have a good story to tell.  Then again, gradually cash out and enjoy,  IRS wasn't lucky, you were, therefore you deserve it all.


Anyways, you should seek legal advice from experts, in here we only see golden coins where ever we look, so we are in a sense mesmerized by medusa, or rather by a gold hoarding dragon.

[Black_Pawn]

Interesting...seeking legal advice and avoiding exchanges... However, how does one convert the coins from these puzzles into spendable cash without an exchange? And it’s somewhat disappointing not being able to spend it all at once if one wishes to, minus taxes and so forth. I haven’t found any legal provision that clarifies the management of bitcoins you ‘find’, or earn from solving a puzzle, or inherit... especially if you aren’t one of the big whales, who I suspect have their systems in place already )

I'm amazed on how people think that CES are the real players in crypto world. In particular I'll NEVER trade any crypto by using Centralized Exchanges.

IF you or anyone find a key just seek for a trusted P2P near you, trade small ammounts and avoid government, or better take everything by cash  buy a house for you, buy another house and rent it and live without any shitty taxes from politics.

Yes, you urgently need to give these keys to me and continue to live in poverty, mama's son

I rather be financially poor than being mentally and morally poor. Though I'm not financially poor, I have never been poor because God has always provided for me, He provides for all living creatures 24/7.

Also it is considered a sin if we keep thinking about the wealth of others and say why God has given them so much and then try to take it from them, instead we should ask God to give us our own wealth from  his own generosity.

Think about it, there is enough gold inside the earth to coat the surface of earth with pure gold, and this is only earth.
When a star explodes, several billion tons of gold is created in a nanosecond, so with this much abundance  why do we have poverty?

If all the people were rich, who would farm, manufacture and work? Not you certainly.🙂

Currently running a 3060ti and getting about 1500kh/s

Looking to add a 4060ti 16 gig or 4070ti 12 gig

I am torn between the two, the 4070 is faster but less ram and only 50$ more. Does anyone have a approximate speed with these running Bitcrack or others?

Also may be used for mining here and there.

[ElDalmatino]

Hmm, is there a python script to get the public key from a Transaction.

[digaran]

Hmm, is there a python script to get the public key from a Transaction.

I don't know about any scripts but you can simply use this site to convert an address to public key and vice versa, though it only does that if the address exist on blockchain, meaning it has been used, otherwise it'd take breaking 2 hash functions to reverse an address back to public key.

May I ask why do you need that? All exposed public keys of this puzzle already are on page 1, there is no need to have such a script.
Also may I interest you in a few mind boggling , reality bending ultimate hack scripts developed by myself?😉

THX for your answer, i try some out of the box research, i think i fall in the BTC rabbit hole in my old days  , so it's my nature to go on and on. At the moment i try something different then all here in, if it works fine, if not, like i allways say " It's only a PC that is running, some burn energy of PC for Gaming, we burn the Energy for education !" 

Shure i am open for all kind of stuff, pm or dm or xm or gm ... me 
And sharing is caring i know, when i got to this level i will share what i found ( don't want to be the dumb newbie from start wit " i got this and that " ).

[digaran]

And sharing is caring i know, when i got to this level i will share what i found ( don't want to be the dumb newbie from start wit " i got this and that " ).

You can find the scripts here. You should share whatever you have here publicly, it's Ok to look like a noob, I'm also a noob myself running around asking stupid questions, but you never know, one of these questions or ideas could lead to a breakthrough. Let me give you a hint, you won't learn new things if you don't share what you know, just try it, share your knowledge and you will see how fast you learn new stuff.
God never lies when he says if you donate, I will give you more than double in this life and thousands of times more in the afterlife.

When you think about it, he gives us knowledge and money, then asks us to share it just to get more. What a nice God.😉
