Satoshi Nakamoto presented the Bitcoin white paper on October 31, 2008, proposing a peer-to-peer electronic cash system designed to prevent double-spending.

Confirmations reduce the risk of a payment being reversed, but their significance depends on the transaction value and the merchant’s procedures.
