A “ledger” refers to a decentralized and distributed record-keeping system that tracks all transactions across a network of computers. The ledger is a fundamental component of blockchain technology, the underlying technology behind most cryptocurrencies like Bitcoin and Ethereum.

The ledger, often called a “blockchain,” is a chain of blocks, where each block contains a list of transactions. These transactions are securely and transparently recorded in chronological order. The decentralized nature of the ledger means that it is not controlled by a single entity but is maintained by a network of participants, often referred to as nodes.

A cryptocurrency ledger is a decentralized and transparent record-keeping system that employs blockchain technology to secure and verify transactions across a network of nodes. It is a foundational aspect of cryptocurrencies, providing a tamper-resistant and trustless environment for financial transactions.
