Fintech & Blockchain Applications MCQs with Answers

15 multiple-choice questions on Fintech & Blockchain Applications for CAF-3 Data, Systems and Risks. Try each one before revealing the answer and explanation.

1. Question 1

   What is the primary feature of blockchain technology that ensures data cannot be altered or tampered with once it is recorded?

   • A) Centralization
   • B) Immutability
   • C) Scalability
   • D) Virtualization
   Show answer & explanation

   Answer: B) Immutability

   Blockchain's primary feature is immutability, meaning once data is recorded in a block, it cannot be modified without the approval of the majority of the network

2. Question 2

   In a blockchain network, what happens if a hacker attempts to alter a transaction within a specific block?

   • A) The network immediately centralizes to protect the data.
   • B) The hash of that block changes, which breaks the link to the next block and invalidates the subsequent chain.
   • C) The block is automatically deleted without affecting the rest of the chain.
   • D) The transaction is approved but flagged for manual review.
   Show answer & explanation

   Answer: B) The hash of that block changes, which breaks the link to the next block and invalidates the subsequent chain.

   If someone alters a transaction, the hash of that block changes. Because each block relies on the previous block’s hash, this disruption breaks the link and invalidates the entire subsequent chain

3. Question 3

   • D) To reduce the number of nodes required in the network
   Show answer & explanation

   Answer: B) To create a unique digital fingerprint of the data within a block

   Hashing is used to create a unique digital fingerprint for the data in a block, linking it securely to the previous block in the chain . --------------------------------------------------------------------------------

5. Question 5

   Bitcoin is a classic example of a public blockchain, which is open, decentralized, and allows anyone to participate in the consensus process

6. Question 6

   An enterprise wants to keep its sensitive internal data private while simultaneously sharing key, non-sensitive information on a public network for transparency. Which type of blockchain is best suited for this?

   • A) Public Blockchain
   • B) Hybrid Blockchain
   • C) Open-Source Blockchain

7. Question 7

   Which Distributed Ledger Technology (DLT) provides decentralized computing without needing global consensus, instead allowing each individual user to maintain a unique "chain" of their own interactions?

   • A) Ethereum
   • B) Bitcoin
   • C) Holochain
   • D) Hyperledger
   Show answer & explanation

   Answer: C) Holochain

   Holochain is a distributed application framework where data is not globally validated; instead, each agent (user) maintains a unique chain of their own interactions

8. Question 8

   In a Proof of Stake (PoS) consensus mechanism, how are validators selected to maintain the integrity of the network?

   • A) Based on the raw computing power (mining hardware) they possess
   • B) Based on their physical geographic location
   • C) Based on the number of coins they hold (their vested interest)
   • D) Based on the speed of their internet connection
   Show answer & explanation

   Answer: C) Based on the number of coins they hold (their vested interest)

   In a Proof of Stake (PoS) network, validators are selected based on the number of coins they hold, ensuring they have a financial stake in maintaining the network's integrity . --------------------------------------------------------------------------------

9. Question 9
