Why do I get a different Private Key ?

# secp256k1 group order N
N = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141

# Inputs
K = 0x695e5e4c01e8ac9d77b7ecdd9881d50bb397ff7e54e082240a19b714c4de7ef8
R = 0x634e6e5d85360927c64d66bdd616dc58ac6b72cd22fac01c544236b63734ad35
S = 0x7fe9088b3849cddb82f38ef9244a06c413addb38031ee01a38e675ff28579d8a
Z = 0x6ad532092bb3f4ee012e61df35c95efc7d9e9fa5653c371bc843fa4b3627f01f

# Step 1: Calculate (S * K - Z) mod N
numerator = (S * K - Z) % N

# Step 2: Calculate modular inverse of R mod N
r_inv = pow(R, -1, N)

# Step 3: Derivation
d = (numerator * r_inv) % N

print(f"Correct Private Key Hex: {hex(d)[2:].zfill(64)}")

Hello.

The K value is incorrect. The real K value is 0x331a8d875ee76008057981c577c6f66e84de443b1a8aad659f338b32c2fad9c1

That's why the Private Key you got is different.

Ahh.... late for the mini-puzzle Undecided

Anyway... congratulations to the solver

Hello there!

Well... now let's move to puzzle # 140 Wink

Good luck to all Cheesy

Hello there!

Congratulations RetiredCoder for solve the puzzle # 135.

Wow.

Congratulations to the solver of the puzzle # 135.

I think that was @RetiredCoder again, because destination address is the same that was used for puzzle # 130.
