  4. Delegation rewards
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In Proof-of-Work (PoW), the primary economic incentive for miners to participate in the consensus process is block rewards. Miners are rewarded with cryptocurrency for successfully solving the complex mathematical puzzle and adding a new block to the blockchain.

Multiple choice

In Proof-of-Stake (PoS), what is the primary economic incentive for validators to participate in the consensus process?

  1. Transaction fees

  2. Block rewards

  3. Staking rewards

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

In Proof-of-Stake (PoS), the primary economic incentive for validators to participate in the consensus process is staking rewards. Validators are rewarded with cryptocurrency for holding their cryptocurrency in a staking pool and participating in the consensus process.

Multiple choice

Which consensus mechanism is generally considered to be more resistant to censorship than Proof-of-Work?

  1. Proof-of-Stake

  2. Proof-of-Authority

  3. Delegated Proof-of-Stake

  4. Practical Byzantine Fault Tolerance
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Proof-of-Stake (PoS) is generally considered to be more resistant to censorship than Proof-of-Work (PoW) because it allows for a wider distribution of validators. In PoS, anyone who holds cryptocurrency can participate in the consensus process, making it more difficult for a single entity or group of entities to control the network.

Multiple choice

Which consensus mechanism is generally considered to be more suitable for applications that require fast transaction processing times?

  1. Proof-of-Work

  2. Proof-of-Stake

  3. Delegated Proof-of-Stake

  4. Practical Byzantine Fault Tolerance
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Proof-of-Stake (PoS) is generally considered to be more suitable for applications that require fast transaction processing times because it is more efficient and allows for faster block confirmation times compared to Proof-of-Work (PoW).
