D Correct answer
Explanation

The Ripple Consensus Protocol (RCP) is known for its ability to handle high transaction throughput and is used in the Ripple payment network.

Multiple choice

In a Delegated Proof-of-Stake (DPoS) consensus algorithm, what is the primary role of delegates?

  1. To validate transactions and create new blocks

  2. To hold a majority of the tokens in the network

  3. To provide computational power to the network

  4. To govern the network and make decisions

A Correct answer
Explanation

In a Delegated Proof-of-Stake (DPoS) consensus algorithm, delegates are elected by token holders to validate transactions and create new blocks.

Multiple choice

What is the primary purpose of Layer-2 solutions in blockchain networks?

  1. To increase transaction throughput and scalability

  2. To enhance the security of the blockchain

  3. To reduce the energy consumption of the blockchain

  4. To improve the decentralization of the blockchain
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Layer-2 solutions are primarily designed to address the scalability limitations of blockchain networks by increasing transaction throughput and reducing transaction latency.

Multiple choice

Which Layer-2 protocol involves the use of recursive sidechains?

  1. Optimistic Rollup

  2. Zero-Knowledge Rollup

  3. Validium

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

Plasma is a Layer-2 protocol that utilizes recursive sidechains, which allows for the creation of multiple layers of sidechains, each with its own set of rules and validators.

Multiple choice

What is the purpose of tokenization in mobile payments?

  1. To encrypt customer data

  2. To replace sensitive data with a unique token

  3. To authenticate the customer

  4. To authorize the payment
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tokenization is the process of replacing sensitive data, such as credit card numbers, with a unique token that can be used to process the payment without exposing the actual data.

Multiple choice

How can blockchain technology be used to promote animal welfare?

  1. It can be used to track the movement of animals throughout the supply chain.

  2. It can be used to create a transparent record of animal welfare practices.

  3. It can be used to develop new ways to finance animal rights organizations.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Blockchain technology can be used to track the movement of animals throughout the supply chain, create a transparent record of animal welfare practices, and develop new ways to finance animal rights organizations.
