What is the primary purpose of cryptography in blockchain security?

  1. To ensure data confidentiality

  2. To prevent unauthorized access

  3. To maintain data integrity

  4. To facilitate consensus among nodes


Correct Option: A
Explanation:

Cryptography plays a crucial role in blockchain security by encrypting data to ensure its confidentiality and prevent unauthorized access.

Which consensus mechanism is commonly used in blockchain networks to achieve agreement among nodes?

  1. Proof-of-Work (PoW)

  2. Proof-of-Stake (PoS)

  3. Delegated Proof-of-Stake (DPoS)

  4. Proof-of-Authority (PoA)


Correct Option: A
Explanation:

Proof-of-Work (PoW) is a widely adopted consensus mechanism in blockchain networks, where miners compete to solve complex mathematical puzzles to validate transactions and add new blocks to the blockchain.

What is the primary economic incentive that drives participation in blockchain networks?

  1. Transaction fees

  2. Block rewards

  3. Staking rewards

  4. Mining rewards


Correct Option: B
Explanation:

Block rewards are the primary economic incentive that encourages miners or validators to participate in blockchain networks. These rewards are given to the nodes that successfully add new blocks to the blockchain.

Which interdisciplinary approach combines cryptography, game theory, and economics to analyze blockchain security?

  1. Cryptoeconomics

  2. Blockchain Forensics

  3. Smart Contract Security

  4. Blockchain Scalability


Correct Option: A
Explanation:

Cryptoeconomics is an interdisciplinary field that merges cryptography, game theory, and economics to study the economic incentives and behaviors of participants in blockchain networks.

What is the primary concern regarding smart contract security?

  1. Vulnerability to cyberattacks
