The consensus process by which the veracity of data is confirmed and verified is known as

• A. Telematics
• B. Machine learning
• C. The Internet of Things
• D. Mining

Answer: (D)

Mining is the mechanism by which a distributed network reaches agreement on the truth of the data. In blockchain-like systems, miners compete to solve a cryptographic puzzle; the winner adds a new block of transactions to the chain and the rest of the network validates that block. Once consensus is reached, the ledger state is updated, and altering past records becomes extremely difficult, which preserves data veracity and integrity. This process directly addresses how data is confirmed and verified across a distributed, tamper-resistant ledger. Telematics, machine learning, and the Internet of Things describe data sources, analytics, or networks, but they do not describe the consensual verification process that validates and finalizes data across the system in the way mining does.
