Hy guys,
I'm studying a nakamoto's wp.
You can find it here:
https://bitcoin.org/bitcoin.pdfI don't understand when he say this:
"We define an electronic coin as a chain of digital signatures. Each owner transfers the coin to the
next by digitally signing a hash of the previous transaction and the public key of the next owner
and adding these to the end of the coin. A payee can verify the signatures to verify the chain of
ownership"
And follows this picture:
How a payee can verify the signatures if in transaction there isn't a public key of previus owner?
Maybe, but isnt write, there is a pointer to the previus transaction where i read the public key and all transaction for calculate the hash?
Thank you guys
