Bitcoin puzzle transaction ~32 BTC prize to who solves it

[tmar777]

Hi guys,

I am not sure if here is the correct place to ask but I need your help.
I need a secure, checked and efficient script that gets binaries (256bit) and returns:

1) private key (c)
2) private key (u)
3) public address in hex
4) public address
5) balance

or at least some of the above. As for the 5, i know that i need a connection to the API, so i prefer to suggest me of two different scripts because i want to run the 1-4 offline locally for speed.

If you have anything in mind TESTED and SECURE please let me know where to look.
Thanks

You should use Bitcrack > https://bitcointalk.org/index.php?topic=4453897.0
There is no need to check balance via API, you just place all funded addresses in a text file and set it as target, then the tool will grind through the range and if there is a match, it will save it to a file.

I've done that already. Waste of time for lower bit ranges and for higher it takes too long.

I can tell you one thing everything that can be stolen on bitcoin blockchain is already stolen

Hello, sorry if this is a dumb question or has already been answered in a place I'm failing to find, I'm wondering if there is there any knowledge (or speculation!) of the methodology which was used in the creation of the transaction?

Many thanks

A few words about the puzzle.  There is no pattern.  It is just consecutive keys from a deterministic wallet (masked with leading 000...0001 to set difficulty).

[kalos15btc]

Some rocket science, some dice, a few weeks of calm and quiet, a few cups of coffee and finally an HD wallet to generate 256 keys and then masking each key with 0s to place each key in a certain bit range.

Replace the strike through characters with 0s and good to go.
I managed to take a snapshot of the situation when #66 is solved.

some mod ban this user please his always reply with nothing to say about the puzzle, this is not a forum for memes, where are your new accounts ? we didint see your self reply to yourself anymore, stay away from this thread we are trying to solve a puzzle here,


P66 is in 20-2F range not in 30-3F.

[AlanJohnson]

P66 is in 20-2F range not in 30-3F.

How do you know that ?

he cannot, just ignore.

[citb0in]

Take your chances by deploying a bot to compete with the looter, otherwise you can kiss your coins good bye. Or just talk  with a large pool beforehand, you could offer them $10,000 bonus and if they include the tx in their block, other pools won't dare to mine that block again just to take those extra coins.

So you are claiming that any Bitcoin transaction could be double-spended and therefore all Bitcoin transactions are insecure. Makes sense ?

What do you think of a challenge? I transfer an amount of x coins, you only know the source address, which I will publish here. Its private key will be in the range of 66bit just like the mentioned puzzle. Then you siphon off the coins and transfer them to another address before I receive them just like you described the looter would. If the coins end up at your freely chosen address, you can keep them. If they end up with me, you have lost and made a fool of yourself. Deal ?

So what's about the RBF-challenge, deal or no deal?
I generate an address with a 66bit private key and send a few coins to it. Then I create a transaction to send the entire contents of this wallet address to any other address. I will explicitly set 1 sat/vB as the fee so that the transaction can stay in the blockchain forever. Now you (or someone else if you like) try to cancel this outgoing transaction and thus simulate a mallory sucker that wants to withdraw the coins. As the transaction has the minimum fee you have all the time that you need.

As the fees are currently very high, I am unfortunately unable to send coins to the RBF-challenge address. If anyone is interested in this RBF-challenge and would like to sponsor some minimum amount of satoshis, here is the wallet address:
1C8uD9G4AGQas5sG15869p5B1mrF3RELY3

I own the private key of this address, here's the signature:

^{Message: This address was exclusively generated for the RBF-challenge <https://bitcointalk.org/index.php?topic=1306983.msg63398077#msg63398077> and I have the private key of this address. citb0in, 2023-12-27

As soon as this address has been funded with a few satoshis by a generous supporter, I could prepare the outgoing transaction as explained. Any funder appreciated
Let me know if anyone's interested in that challenge.

[_Counselor]

It seems as though nobody is knowledgeable enough to figure out as to why generator points of 2 curves secp and secq256k1 both when divided by 2 generate the same coordinates. Either the so called "experts" and "cryptographers" are clueless as well or they refuse to reveal the secret. Asking questions on other platforms seems to produce the same scripted answers.

It's just because both generators were created by doubling the same point.

Please fund your challenges or don't have a challenge.
Miners decide which transaction to include in blocks and any serious miner will chose those with the highest fees. So I don't see why we need such challenge.

[3dmlib]

Let me know if anyone's interested in that challenge.

I'm interested. I can do.
Do I need to place some low free transaction with RBF off with 100usd on it and say everybody a private key? Yes?
And we'll see if transaction can be modified with RBF flag off? Yes?

[citb0in]

No 100 USD man, just the minimum possible account you can send. Let's say 0.0001 BTC. Send 0.0001 BTC to 1C8uD9G4AGQas5sG15869p5B1mrF3RELY3 and choose an appropriate fee that is ok for you, 145 sat/vB ? By this the mentioned address that is controlled by me should be funded soon. As soon as this RBF-challenge address is funded I will generate the outgoing transaction with 1sat/vB, so it will take forever to be executed. This means the potential attacker has huge time available to redirect the transaction to his address of choice and keep the coins.

We're just gonna simulate if and how a bad boy could make such an attack to the real puzzle 66 (67, 68 ...) hit

I think it will be more interesting to attacker get 100 usd, not 0.0001 btc
Can I do it on my own address and post private key here?

[citb0in]

did you really understand what this RBF-challenge is all about?

[3dmlib]

did you really understand what this RBF-challenge is all about?

Yes. I'll find puzzle 66 in a next few months and I don't want to be my money be stolen on transaction

[citb0in]

perfect, so you're on the right path

Good luck....

awesome ! I have some cuda functions for Point add and Point Mult, and a basic script working but I need to fix it, sometimes it works and sometimes not...

Using a 66-bit private key is like make a transaction, and few seconds after make the private private key "public".

Retrieving such private key from a public key is matter of seconds with a GPU.

A suggestion for your challenge:

1) choose an address where you have already a few satoshi

2) make a tx with fee = 1 satoshi from this address

3) public here a range of 2^66 range in which your private keys is

It is the same challenge, but you save a tx.

[Woz2000]

The attacker will not get $100USD. Most of it will go to the miners in fees. Save your money, I know you have more than you need  but no point wasting it, save it for another day or donate it to someone in need. It is the holidays!   

No 100 USD man, just the minimum possible account you can send. Let's say 0.0001 BTC.

I don't see the challenge in RBF, donate it to the kangaroo or keyhunt project, this is giving more money to the miners.
