Title: Calculating Z Values for a Bitcoin Transaction Post by: BTCMORGAN on February 19, 2017, 06:23:23 PM I know this has been likely asked before, but I've done research and can't seem to find an answer that allows a non-technical person such as myself to simply do this.
Is there a script (E.g.python) that I could use to automatically calculate the Z values? Title: Re: Calculating Z Values for a Bitcoin Transaction Post by: achow101 on February 19, 2017, 07:02:22 PM What Z value? There is no value in a Bitcoin transaction or in ECDSA signatures that is called "Z".

ECDSA digest for signingThanks Amaclin! This is what I was looking for and its good explanation. Is there any code that can do this automatically by pulling a transaction ID off the blockchain (which would import the details)?

I can write such program. Are you ready to pay for it?And why do you want to check the txid? It is so boring! Why not to pass the blockId (hash or height) to a program and check all transactions in block? |
