While blinding in ECC is not really practical for performance applications, it would be a good teaching opportunity to show how blinding can be performed in ECDSA signatures.
the new equation for s would be as follows:
s = inv_blind * inv_k * (blind * m + blind * r * priv_key) % order
where inv_blind and inv_k are multiplicative inverses modulo order of blind and k respectively
