A ledger is a system or tool used to record financial transactions, asset ownership, or other data in a structured and secure manner. There are different types of ledgers used in various domains:
- Traditional Ledger – A physical or digital book used in accounting to track financial transactions, such as sales, expenses, and payments.
- Blockchain Ledger – A decentralized, distributed ledger used in Web 3.0 and cryptocurrencies to record transactions securely and transparently without a central authority.
- General Ledger – The primary accounting record of a company that consolidates all financial transactions.
- Sub-ledger – A detailed record that feeds into the general ledger, such as accounts payable, accounts receivable, or inventory ledgers.
