Questions and Answers
  • 1. 

    What's a blockchain?

    • A.

      A block of chains

    • B.

      A list of records called block

    • C.

      A music album

    • D.

      None of the above

    Correct Answer
    B. A list of records called block
    Explanation
    A blockchain is a list of records called blocks. Each block contains a set of transactions or data, and is linked to the previous block through a cryptographic hash. This creates a chain of blocks, where each block references the previous one, hence the term "blockchain". This technology is commonly used in cryptocurrencies like Bitcoin, where it ensures the security and immutability of transactions.

    How are blockchains linked?

    • A.

      Connection

    • B.

      Gum

    • C.

      A software

    • D.

      Cryptography

    Correct Answer
    D. Cryptography
    Explanation
    Blockchains are linked through the use of cryptography. Cryptography is a method of securing information by converting it into a code that can only be deciphered with the correct key. In the context of blockchains, cryptography is used to create a secure and tamper-proof link between blocks of data. Each block contains a unique cryptographic hash that is generated based on the data within the block and the hash of the previous block. This creates a chain of blocks, where any change in the data of a previous block would result in a different hash, alerting the network to tampering attempts.

    Which is true, blockchains are secured.

    • A.

      True

    • B.

      False

    • C.

      Yes

    • D.

      I don't know

    Correct Answer
    A. True
    Explanation
    Blockchains are secured because they use advanced cryptographic techniques to ensure the integrity and immutability of data. Each block in the blockchain is linked to the previous block through a cryptographic hash, making it extremely difficult for anyone to tamper with the data without being detected. Additionally, blockchains often employ consensus mechanisms, such as proof of work or proof of stake, which further enhance the security of the network by requiring participants to validate transactions and reach a consensus before adding them to the blockchain. Overall, these security measures make blockchains highly secure and resistant to hacking or unauthorized modifications.

    Correct Answer
    B. To work as a ledger
    Explanation
    The correct answer is "To work as a ledger." A ledger is a record-keeping system that tracks transactions and balances. In the context of cryptocurrencies like Bitcoin, a blockchain acts as a decentralized ledger that securely records all transactions. It ensures transparency, immutability, and eliminates the need for intermediaries like banks. Therefore, the creation of blockchain technology was primarily aimed at functioning as a ledger to enable secure and transparent transactions in the cryptocurrency ecosystem.
