How does a "transaction" differ from a "block" in blockchain?

• A. A transaction is a single entry, while a block contains multiple transactions
• B. A block is a transaction that has been validated
• C. A transaction and a block are interchangeable terms
• D. A block is a series of failed transactions

Answer: (A)

A transaction refers to a single operation or entry within the blockchain, representing the movement of value or information, such as transferring cryptocurrency or recording a contract. Each transaction includes details like sender, recipient, and amount, and is essentially the building block of operations conducted on the blockchain. On the other hand, a block is a collection or grouping of multiple transactions that have been validated and recorded together on the blockchain. Once a block is filled with transactions, it undergoes a validation process, and upon consensus, it is added to the blockchain, creating an immutable record. This difference in scope is crucial for understanding blockchain functioning. While individual transactions are essential for conducting business or operations, blocks serve as the structural components that form the blockchain's chronological chain of entries, enhancing transparency and security.
