  1. Public blockchain

  2. Private blockchain

  3. Consortium blockchain

  4. Hybrid blockchain
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A private blockchain is a type of blockchain network that is permissioned and controlled by a specific organization or group of organizations, providing restricted access and increased privacy.

Multiple choice

Which of the following is not a potential benefit of using blockchain technology for voting systems?

  1. Increased transparency and accountability

  2. Enhanced security and integrity

  3. Reduced voter fraud

  4. Increased voter turnout
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

While blockchain technology can offer benefits such as increased transparency, security, and reduced voter fraud, it is not directly associated with increasing voter turnout.

Multiple choice

What is the term used to describe a type of blockchain network that combines elements of both public and private blockchains?

  1. Public blockchain

  2. Private blockchain

  3. Consortium blockchain

  4. Hybrid blockchain
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A hybrid blockchain is a type of blockchain network that combines elements of both public and private blockchains, allowing for a mix of permissioned and permissionless access.

Multiple choice
