In the context of cryptocurrency and blockchain technology, a ledger is essentially a digital record-keeping system that maintains a comprehensive list of all transactions within a network. Here are some key points about ledgers:
Transaction Record: The ledger records every transaction from the very first coin to the most recent, allowing for complete traceability of all transactions.
Distributed Nature: Unlike traditional ledgers that are centralized, a blockchain ledger is distributed across multiple nodes (computers) in the network. Each node maintains an identical copy of the ledger, ensuring that all participants have access to the same information.
Security: Transactions are grouped into blocks and secured using cryptographic techniques. Each block contains a hash value that links it to the previous block, creating a chain. If any attempt is made to alter a transaction, the hash value would change, making it evident that tampering has occurred.
