Title: Understanding White Paper Nakamoto Post by: pf55351 on June 01, 2018, 12:00:03 PM Hy guys,
I'm studying a nakamoto's wp. You can find it here: https://bitcoin.org/bitcoin.pdf (https://bitcoin.org/bitcoin.pdf) I 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: https://i.stack.imgur.com/HUZQ2.jpg 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 |
