Satoshi Nakamoto introduced a peer-to-peer electronic cash proposal on October 31, 2008. The paper proposed using digital signatures and a shared proof-of-work history to verify payments without a central transaction ledger and prevent double-spending. A signature alone cannot show whether the same funds were offered in a competing transaction.
The source notes that a broadcast payment is not the same as one included in a block, and merchants still need to judge confirmation risk. The network can provide evidence of a coin transfer, but it cannot verify the wider commercial agreement or resolve disputes about it. The paper also does not describe every feature of modern Bitcoin software or establish Bitcoin’s value.
