Research direction
The issue does not name files, tests, or an entry point. Start by locating the ECDSA signing implementation and its existing scalar-arithmetic tests, then determine how blinding should fit the public API and test vectors. Done means a reviewed blinding design, implementation, and coverage demonstrating the stated equation.
Written by the indexing model from the issue text.
Description
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
