Multiple choice

Which consensus mechanism is primarily used in the Bitcoin blockchain?

  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
A Correct answer
Explanation

Proof-of-Work (PoW) is the consensus mechanism used in the Bitcoin blockchain. It involves miners solving complex mathematical puzzles to validate transactions and add new blocks to the blockchain.

Multiple choice

In a Proof-of-Stake (PoS) consensus mechanism, the probability of a node being selected to validate a block is proportional to its:

  1. Computational power

  2. Age of the node

  3. Number of transactions processed

  4. Amount of cryptocurrency staked
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In PoS, the probability of a node being chosen to validate a block is directly proportional to the amount of cryptocurrency it has staked.

Multiple choice

Which consensus mechanism is designed to tolerate Byzantine faults, where nodes can behave arbitrarily and maliciously?

  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
D Correct answer
Explanation

Practical Byzantine Fault Tolerance (PBFT) is a consensus mechanism designed to tolerate Byzantine faults. It ensures that a distributed system can reach consensus even in the presence of malicious nodes.

Multiple choice

Which consensus mechanism is commonly used in permissioned blockchains, where participants are known and trusted?

  1. Proof-of-Work

  2. Proof-of-Stake

  3. Delegated Proof-of-Stake

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

Delegated Proof-of-Stake (DPoS) is often used in permissioned blockchains. It involves a set of elected delegates who are responsible for validating transactions and maintaining the blockchain.
