Using the "message signing" feature in the Bitcoin and Dash it's static with the same message. Signing the same message with the same private key will result always in the same signature.

This behavior is not the same in Peercoin or in the old wallet of Bitcoin. In these wallets, the signature changes even if the message isboth messages are equal, for me it has some "nonce" inside.

ExempleExample:

Message: xxx

Address: 18ZbyqYYwgEmn5hVMtJpihPeYxsUpCLhr7

In the old Bitcoin-qt the same message with the same private key create different signatures. But in the new Bitcoin-qt it's result in the same signature.

I'm using the btcec.RecoverCompact from this library, this only work in the first case (when same message is always same signature), but not work in another case.

What is the difference between this signature method? Have an alternative to continue getting the PK from a signature in the second case? Have name of this specific change?

Why the signature of the same message changes in some wallets, but not all?
