For ECDSA you can’t provide a signature isn’t arbitrary data. The nonce is by definition not known, so it contains enciphered information.

- Dylan16807 7y agoI think you mean it can't be proven not to have 8 bytes of enciphered information. But anyway, you can use a hash function to generate the 8 bytes of nonce.
- RL_Quine 7y agoYou can’t prove you did without revealing the nonce, and therefor the private key.
- Dylan16807 7y agoYou could reveal it once the transaction is used. If anyone really doubts your 8 bytes.
- firethief 7y agoThat's true but not relevant here because the intent of the signatures is not to conceal the nonces.
