CBSE Credential Curriculum and Topics 3

Question 1

Which CBSE topic area addresses the process of formally verifying smart contract logic before deployment?

Accepted Answer

Formal Verification and Auditing

Answer

Formal Verification and Auditing covers mathematical proof techniques and code audit methodologies used to confirm that smart contract behavior matches its specification.

Question 2

A CBSE professional is reviewing a DeFi protocol's flash loan mechanism. Flash loan attacks are dangerous primarily because they allow attackers to do what?

Accepted Answer

Borrow large amounts of capital with no collateral within a single transaction block

Answer

Flash loans provide uncollateralized capital within a single atomic transaction, allowing attackers to manipulate prices or exploit vulnerabilities at scale with no upfront capital risk.

Question 3

The CBSE curriculum covers cryptographic hash functions. Which property ensures that two different inputs cannot produce the same hash output?

Accepted Answer

Collision resistance

Answer

Collision resistance means it is computationally infeasible to find two distinct inputs that produce the same hash digest, protecting blockchain integrity.

Question 4

In the CBSE body of knowledge, what is the primary security concern with using a deterministic wallet (BIP-32 HD wallet)?

Accepted Answer

Compromise of the master seed exposes all derived child keys

Answer

Because all child keys are derived from a single master seed in a BIP-32 HD wallet, an attacker who obtains the seed gains control over every address in the wallet hierarchy.

Question 5

Which CBSE curriculum topic examines the risks posed by Miner/Maximal Extractable Value (MEV) to blockchain fairness and security?

Accepted Answer

Consensus and MEV Security

Answer

Consensus and MEV Security explores how validators or miners can reorder, insert, or censor transactions to extract value, undermining transaction fairness and protocol integrity.
