Public Ledger

A public ledger is a transparent, shared record-keeping system accessible to anyone, where all transactions are permanently stored and openly visible. It ensures accountability and trust without relying on a central authority, often using blockchain technology. For example, in cryptocurrencies like Bitcoin, the public ledger logs every transaction, allowing users to verify balances and transaction histories independently. This decentralization prevents fraud and double-spending, fostering confidence in the system's integrity while maintaining transparency for all participants.
