Since in an ECDSA signature the "r" value is the x coordinate of the corresponding point generated using the ephemeral key k, the only way to reproduce "r" is to reproduce the random k. To reproduce k is the same as reproducing any already used private key!
This also has nothing to do with "sigscript" and "knowledge of blockchain" it is purely basic elliptic curve cryptography.
Meta is not the correct place for this topic by the way.
Topic: New way to get similar "r" value (Read 75 times)
i think i may have found a way to get same "r" value in sigscript in transactions of particular address, i need someone who has good knowledge of blockchain to review it
