This script generates x-only Schnorr keys on the secp256k1 curve, constructs Kaspa addresses from them, and verifies their correctness through reverse decoding.

Goatghosts / get_lamda.py

I was playing with the constants related to the implementation of endomorphism on the secp256k1 curve, and through strange manipulations, I was able to derive LAMBDA and LAMBDA^2 from B1 and B2. I am not familiar with the original document, so this was a bit of a discovery for me. But overall, there's probably nothing useful here.

We turn the integer variable into a binary format, add a bit in front, remove a bit in the back, and convert back to an integer variable.

Last active October 22, 2024 18:46

Many people know how to get a private key from a nonce. But I did not find information on how to get a nonce from a private key. If someone also does not know how to search, then here is a ready-made solution. And here is what I took as a basis: https://asecuritysite.com/ecdsa/ecd3

	import ecdsa
	import random
	import libnum
	import hashlib


	G = ecdsa.SECP256k1.generator
	ORDER = G.order()
