What names are given to a database where all cryptocurrency transactions are recorded?

• A. Blockchain
• B. Crypto Ledger
• C. Ledger
• D. Blockchain & Ledger

Answer: (D)

In cryptocurrency, transactions are recorded in a distributed ledger. This ledger is implemented as a blockchain, which is a chain of blocks that contain transaction data and are linked together with cryptographic hashes. Because the ledger is maintained by many participants across a network, it becomes tamper-evident and transparent. The term ledger is the traditional way to refer to a record of transactions, while blockchain describes the specific technology used to realize that ledger. So, both names are commonly used to describe the database that holds all cryptocurrency transactions, making "Blockchain & Ledger" the most accurate choice. The other options are less precise: a crypto ledger or a ledger alone is correct in a general sense but doesn’t capture the specific technology, and blockchain alone highlights the method but not the broader term.
