Which term describes the consensus process by which the veracity of data is confirmed and verified?

• A. Telematics
• B. The Internet of Things
• C. Artificial Intelligence
• D. Mining

Answer: (D)

Mining is the term for the consensus process that confirms and verifies data in a blockchain. In mining, participants collect pending transactions, compete to solve a cryptographic puzzle, and the winner bundles these into a new block. That block is broadcast and verified by other nodes; once consensus is reached, the block is added to the chain and its data is considered verified and permanent. This mechanism ensures veracity because tampering with past blocks would require redoing the work across the entire network, which is highly impractical. The other terms relate to data collection (telematics, IoT) or data processing (artificial intelligence) rather than the act of achieving consensus to confirm data integrity.
