Multiple choice

What is the primary ethical concern associated with blockchain technology?

  1. Transparency

  2. Decentralization

  3. Privacy

  4. Scalability
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Blockchain technology's public and immutable nature can raise privacy concerns, as transactions and data are permanently recorded on the blockchain.

Multiple choice

How does blockchain's decentralization impact its security?

  1. It makes the blockchain more vulnerable to attacks.

  2. It increases the blockchain's resistance to censorship.

  3. It slows down the blockchain's transaction processing speed.

  4. It makes the blockchain more energy-intensive.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Blockchain's decentralized nature makes it more difficult for a single entity to control or censor the network, enhancing its resistance to censorship.

Multiple choice

Which of the following is NOT a potential benefit of blockchain technology?

  1. Increased transparency

  2. Reduced transaction costs

  3. Enhanced security

  4. Centralized control
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Blockchain technology is inherently decentralized, meaning it is not controlled by any single entity. Centralized control is not a benefit of blockchain.

Multiple choice

How does blockchain's immutability affect the resolution of errors or fraudulent transactions?

  1. Errors and fraudulent transactions can be easily reversed.

  2. Errors and fraudulent transactions can be corrected with a majority consensus.

  3. Errors and fraudulent transactions cannot be reversed or corrected.

  4. Errors and fraudulent transactions can be corrected by the blockchain's creator.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Due to blockchain's immutability, once data is recorded on the blockchain, it cannot be altered or removed, making it challenging to resolve errors or fraudulent transactions.
