Bitcoin puzzle transaction ~32 BTC prize to who solves it

[joseperal]

It's not like the 02 or 03 were chosen arbitrarily. It's stupid to check for a collision by doing both 02 and 03. Just stick to the correct parity of the actual Y of the point.

I could save some time there, calculating only what has to be calculated, C-02 or C-03, but...

If it is stupid, why people sent funds to all 3, compressed-02, compressed-03 and uncompressed-04 addresses of the same private key?, by error? just for testing? who knows...

I discovered this by accident, because did not understand which is the check on the private key, to decide which Compressed-02 or compressed-03 Id I must use, so I did both, and also the other U-4, C-6 and C7 and calculated everything else up to the ripemd160 hash, and searched all 5 in my list of list 53M ripemd160 hashes with balance. Just in case there is a treasure somewhere.

For example, private key 1,

Private key 0 (I know it is not valid point of the curve), is also interesting. People also sent funds to all 3 Addresses! Could this be considered a black hole address?

I blacklisted this 3 ripemd160 to avoid confusions, and getting excited for nothing, I believe they are invalid addresses:

Public Address, Balance, Transactions,ripemd

It is interesting there is a lot of transactions reported for all the 3 ripemd160... this might be an error of the python parser I am using to scrap the bitcoin addresses with balance (https://github.com/graymauser/btcposbal2csv).

I have no idea what they mean...

[kTimesG]

I could save some time there, calculating only what has to be calculated, C-02 or C-03, but...

If it is stupid, why people sent funds to all 3, compressed-02, compressed-03 and uncompressed-04 addresses of the same private key?, by error? just for testing? who knows...

I discovered this by accident, because did not understand which is the check on the private key, to decide which Compressed-02 or compressed-03 Id I must use, so I did both, and also the other U-4, C-6 and C7 and calculated everything else up to the ripemd160 hash, and searched all 5 in my list of list 53M ripemd160 hashes with balance. Just in case there is a treasure somewhere.

You are confusing a lot of things.
Private Key is a scalar value.
Public Key is an EC point (X, Y) and Y has a parity (e.g. least significant bit odd or even, 1 or 0).
Y is a function of X.
So a public key can be uncompressed (04) in full (X, Y) form or compressed with just X and the Y parity (02 or 03 byte hint prefix)

If you are doing blind searches in hope of a collision, and you have a private key interval, you need to use the correct Y parity to produce the hashed address, otherwise you are hashing the address for private key N - k which is always outside your private key search interval (for all intervals lower than N/2 in size, which is ~ 2^255), and the Y value is negated, hence the key for (X, -Y) = (X, P - Y). -Y = P- Y is always odd if Y is even, and viceversa, because P is odd.

If you are doing blind searches in hope of a collision and you don't have a private key interval in mind (so full-blown 256-bit keyspace), then your goal is to produce as fast as possible public keys, in which case you can use symmetry (02 / 03) and the 3-cycle endomorphism ±k*lambda^i -> (X*beta^i, ±Y) to quickly compute 6 (2 * 3) private keys and their points (public keys) for every generated (private key, public key) pair. So it ends up as an optimization problem to do as fast as possible key generation with lowest amount of multiplications involved, since it was explained earlier that multiplication is the highest overhead of any possible group operation (since it's basically just rounds of additions).

The only number I am aware of that is larger than the number of all possible Bitcoin private keys is the number of electrons in the Universe (around 2-3 electrons for every possible BTC private key).

Hey Guys,, the Question is about Kangaroo. i'm a bit confused..  the kangaroo designed by JeanLucPons. is the program restricted to work only inside the range of 125 bits? if yes what does it mean? because i tried it with a 130 bit range and it seems to work and in the issues section i see people talking about how it wouldn't work for 130 bits can someone tell me what they are talking about ?

[Filip8472]

Could someone take a look at my smaller application/website for calculating smaller ranges to see if it uses the correct calculations ?    http://cosmiccat.unas.cz/ (You need to use HTTP instead of HTTPS. It's some random free web hosting, don't worry)

The program is limited to a range width of 125 bits or less.

The range width is the upper bound of the range minus the lower bound.

You can find the discussion about this on the kangaroo thread;

I guess he's implying that he found some <80 bits solution and he posted here some proof hash so the Collective assists him morally once the pubkey gets leaked and hundreds of TX will fight over the fee in the next 10 seconds.

Hello friends, it's time to make it public.
I hope these findings will help you find the keys.
The program used is Adobe Illustrator, where the keys are placed together around a spiral axis and separated by a distance.
The coloring is adjusted according to the work of zahid888.
What is strange is that with the font number 10 and the distance between the numbers of 600, we have an order and the colors are automatically placed in their own categories.
The stars selected in black color are the position of key number 66, and the next stars are placed in order up to key 70.
I have many more things and more detailed arrangements, and if I can and my condition allows, I will make them public.
Note that the private keys are in decimal format
Don't forget me if I helped you reach the key.

Do you really not know what to do?
Convert it to hex and generate an address and compare it with the addresses of the puzzle! Maybe luck is with you

Can anyone make windows CMD program with the Idea of this script for multiple GPUs?
 The changebles to be:

 num_objects = random.randint(15,15) - THESE VALUES
            random_values = random.sample(range(0, 29), num_objects) - THESE VALUES
            random_values.append(29) - THIS VALUE
 target_hash160 = 'd39c4704664e1deb76c9331e637564c257d68a08' - THIS VALUE

I am sorry for asking but I don`t have the proper programing skills to do this.
I`ve been playing with python to try to run this script with GPUs but... I just can`t ;(

Are we supposed to solve a 66 bit private key by looking at a gif and a picture? It more looks like a soccer ball than anything. What exactly is happening here, what should people do after looking at the image?

Hello friends, it's time to make it public.
I hope these findings will help you find the keys.

Any series of strings in continuous increasing length starting from some center point and spiraled around in ascending length order will produce arms.
Why? Because they increase in same length, so for any element X(i) its length is length of X(i-1) * someConstant, so eventually their starting points on the circle's perimeter will get aligned, depending on how far from the center you position it.

This happens for any rational and non-rational number that exists, except for phi (1+sqrt(5))/2 and its family. That one is the single possible ratio that always wraps in full uniform distribution and is seen all over in nature.

Well, since we are here I'd like to ask what y'all think of this:

Code:

import numpy as np
import matplotlib.pyplot as plt
from scipy.interpolate import splev, splrep
from decimal import Decimal

sequence = [
1, 3, 7, 8, 21, 49, 76, 224, 467, 514, 1155, 2683, 5216, 10544, 26867, 51510, 95823, 198669, 357535, 863317, 1811764, 3007503, 5598802, 14428676, 33185509, 54538862, 111949941, 227634408, 400708894, 1033162084, 2102388551, 3093472814, 7137437912, 14133072157, 20112871792, 42387769980, 100251560595, 146971536592, 323724968937, 1003651412950, 1458252205147, 2895374552463, 7409811047825, 15404761757071, 19996463086597, 51408670348612, 119666659114170, 191206974700443, 409118905032525, 611140496167764, 2058769515153876, 4216495639600700, 6763683971478124, 9974455244496707, 30045390491869460, 44218742292676575, 138245758910846492, 199976667976342049, 525070384258266191, 1135041350219496382, 1425787542618654982, 3908372542507822062, 8993229949524469768, 17799667357578236628
]

x_values_known = np.arange(len(sequence))
sequence_decimal = [Decimal(value) for value in sequence]
spline_rep = splrep(x_values_known, sequence_decimal, k=2)
extended_x_values = np.arange(len(sequence) + 1)
predicted_next_number = splev(extended_x_values[-1], spline_rep)
predicted_next_number_hex = hex(int(predicted_next_number))
plt.plot(x_values_known, sequence_decimal, label='sequence')
plt.plot(
    extended_x_values,
    splev(extended_x_values, spline_rep),
    label='Recreated Sequence',
    linestyle='dashed'
)
plt.scatter(
    extended_x_values[-1],
    float(predicted_next_number),
    color='red',
    marker='o',
    label='Predicted Next Number'
)
plt.legend()
plt.xlabel('Index')
plt.ylabel('Value')
plt.title('Original vs. Recreated sequence with Prediction')
plt.show()
print(f"Next key: {predicted_next_number}")
print(f"Hexadecimal: {predicted_next_number_hex}")

This is the result when we feed the script the sequence of keys up to #64, in order for it to "predict" #65:

Next key: 3.0520846598475555e+19
Hex: 0x1a78fd44662532000

Is this jesus toast or could we use it to at least try and narrow down the first 2 characters of #66?

Your insights are much appreciated.
