Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Blockchain systems face scalability challenges due to high transaction fees, slow transaction processing times, and limited block size, which can hinder their ability to handle large volumes of transactions.

Multiple choice

Which consensus mechanism is known for its scalability and energy efficiency?

  1. Proof-of-Work (PoW)

  2. Proof-of-Stake (PoS)

  3. Delegated Proof-of-Stake (DPoS)

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

Proof-of-Stake (PoS) is a consensus mechanism that is more scalable and energy-efficient compared to Proof-of-Work (PoW), as it does not require extensive computational power to validate transactions.

Multiple choice

What is the concept of sharding in the context of blockchain scalability?
