Ledger
A record of all transactions. In blockchain, the distributed ledger is maintained across all nodes in the network.
Why It Matters
A ledger in cryptocurrency refers to a record of all transactions on a blockchain. It’s central to how cryptocurrencies function, providing transparency and preventing fraud by ensuring all transaction histories are visible and verifiable.
Example
For instance, when you send or receive Bitcoin, that transaction is recorded in the Bitcoin ledger. This public record allows anyone to verify that the coins exist and were transferred correctly, maintaining trust in the system.
Beginner Context
For beginners, knowing what a ledger is helps demystify how blockchain technology operates. It's like a digital notebook where every transaction is logged, making cryptocurrencies traceable and secure.
