You gotta study up, can’t explain everything here. But yeah, AI can help you learn if you ask the right questions.

+K and -K are points and k is just an integer. So you can do this: K = (x/s) * PubKey + (z/s) * G or even K = k * G k=randint(1,N) # just pick a random number. Good luck finding it. You can technically derive "k"…

In Sagemath, it looks like this: sage:# prime [type:integer] but prime sage:P = 115792089237316195423570985008687907853269984665640564039457584007908834671663 sage:# Elliptic Curve y2=x3+7 for P [type:curve] sage:E =…

Hey, just a heads up, in "R = E.lift_x(r)" there are two options for R. You could get either "R" or "-R". If your public_key is a point object rather than a string, like G, then you should use "R = u2 * public_key + u1…

Oh hey I asked some AI out of curiosity about this acceleration topic, and it mentioned that it’s really more about ECDLP issues.

Hi all. I might have misunderstood something here. I'm familiar with elliptic curve operations and signature algorithms. I get the attack methods too. Just trying to grasp your explanation better. I feel some bias here,…

Hey, I checked out the diagram. If we call the public key big X, what happens to X in the elliptic curve process when K is 1.15?

Hi there. I struggle with C or C++ math operations in those languages are tough for me. I stick to Python and the Fastecdsa Library for developing algorithms. I switch to C or C++ later for performance, and then I can…

We are not being optimistic anymore, I agree and increase the bet.

i will review Thanks alexeyneu

Quick question here. I get asserts in Python, but I’m confused about what the first '48' means. I want to break down the

Thanks for the reply! I’m not gonna mess with repeated R values anymore. Just looking to run some tests and get better at parsing blockchain data. Really appreciate the insight, pooya87. I had this idea after watching…

Hey there! Is it possible to pull out all the signatures from the blockchain and grab the R values? Any tips on how to do that? Just checked a link that has the data. Tried it with Python but it’s super slow. Anyone got…

About your private key, the info you gave isn’t right, here’s how it should look. Using the right library is key, I recommend pycoin for Python. Good luck with that.

Hi, I think I figured this out. The issue is the "SIGHASH_SINGLE bug". After the first sig, the rest all have a hash of "0100000000000000000000000000000000000000000000000000000000000000". I tested it and got it to…

Hey, appreciate the insights! Hoping I can do this manually. I want to really grasp the validation process. I’ve laid out an example:…

Hey Albert, Thanks for the info! I’ll look it over again. I’ve been around this topic for a bit. I want to break it down with an example from the TX I mentioned. Gonna share my sagemath log. The signature isn’t…

Hey there. I’ve been struggling to verify a signature. When I get the Z value, the Kx value of point K (or R) doesn’t match. Am I messing up the message calculation? I keep seeing repeated S and R values in the…
