  2. Proof-of-Stake (PoS)

  3. Delegated Proof-of-Stake (DPoS)

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

Proof-of-Work (PoW) is a consensus mechanism that requires miners to solve complex mathematical puzzles to validate transactions and add new blocks to the blockchain. This process is computationally intensive and consumes a significant amount of energy.

Multiple choice

What is the primary concern regarding the sustainability of blockchain technology?

  1. High energy consumption

  2. Scalability issues

  3. Security vulnerabilities

  4. Lack of regulation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The primary concern regarding the sustainability of blockchain technology is its high energy consumption, particularly in networks that use the Proof-of-Work (PoW) consensus mechanism.

Multiple choice

Which consensus mechanism is considered more energy-efficient compared to Proof-of-Work?

  1. Proof-of-Stake (PoS)

  2. Delegated Proof-of-Stake (DPoS)

  3. Practical Byzantine Fault Tolerance (PBFT)

  4. Proof-of-Authority (PoA)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Proof-of-Stake (PoS) is a consensus mechanism that selects validators based on the amount of cryptocurrency they hold. This eliminates the need for energy-intensive mining, making it a more sustainable alternative to Proof-of-Work.
