    How does blockchain achieve its tamper-resistant

    quality?
    A Through centralized control Correct Answer Incorrect Answer
    B By encrypting data Correct Answer Incorrect Answer
    C With a chain of linked transactions Correct Answer Incorrect Answer
    D By distributing data across multiple nodes Correct Answer Incorrect Answer
    E All of these Correct Answer Incorrect Answer

    Solution

    Blockchain's tamper-resistant quality comes from its decentralized nature. Data is replicated across multiple nodes in a network, and each block contains a cryptographic hash of the previous block's data, making it extremely difficult to alter historical records without consensus from the majority of the network.
