Hello.
I could not verify the signature in this process. When I find the Z value, the Kx value of point K (i.e. R) is not verified. Am I wrong in calculating the message. also in terms of the difficulty of verification
You will see repeated S and R values in the signatures.

Does anyone know how the signature verification is done mathematically in this TX?
Thank you.
