Can the difference be determined between two nonces k1, k2, having a linear relationship if the nonce and private key are unknown, i.e., k2 - k1 = n?

This is trivially broken. Given: (1) s1 = (z1 + r1d) / k1 (2) s2 = (z2 + r2d) / k2 (3) k2 = k1 + d Substituting (3) into (2), eliminating k2: (4) s2 = (z2 + r2d) / (k1 + d) Solving (1) for k1: (5)...
