Which CBSE curriculum module addresses the forensic analysis of blockchain transactions to trace illicit fund flows?
Answer: Blockchain Forensics and Chain Analysis
Blockchain Forensics and Chain Analysis covers techniques for tracing cryptocurrency transactions, identifying mixers or tumblers, and supporting law enforcement investigations of financial crimes.
According to CBSE standards, what is the primary purpose of a Hardware Security Module (HSM) in a blockchain context?
Answer: To generate, store, and use cryptographic keys in tamper-resistant hardware
An HSM is a dedicated hardware device that securely generates, stores, and performs cryptographic operations with private keys, ensuring keys never exist in plaintext outside the module.
A CBSE candidate reviews a Proof-of-Stake blockchain's long-range attack risk. Why are long-range attacks a concern unique to PoS systems?
Answer: PoS validators can reuse old private keys to rewrite history from a past checkpoint without re-doing expensive computational work
In PoS, an attacker who obtains old validator keys can rebuild an alternative chain from a historical point cheaply, since no real computational work is required, unlike PoW reorg costs.
The CBSE exam tests knowledge of multi-party computation (MPC) wallets. What primary security advantage does MPC offer over standard multi-signature wallets?
Answer: MPC allows threshold signing without any single party ever holding a complete private key
MPC (Multi-Party Computation) wallets distribute key shares so that no single party ever reconstructs the full private key, reducing single points of compromise versus traditional multisig approaches.
In the CBSE body of knowledge, which attack on a blockchain P2P network isolates a victim node by controlling all of its peer connections?
Answer: Eclipse attack
An eclipse attack surrounds a target node with attacker-controlled peers, cutting it off from the honest network and allowing the attacker to feed it manipulated blockchain data.
Which CBSE curriculum topic covers the secure implementation of token standards like ERC-20 and ERC-721, including approval vulnerabilities?
Answer: Token Standard and Implementation Security
Token Standard and Implementation Security examines pitfalls in ERC-20/721 implementations, including unlimited approval abuse, reentrancy in transfer hooks, and metadata manipulation in NFTs.
A CBSE professional must advise on securing a blockchain project's CI/CD pipeline. Which threat is most specific to smart contract deployment pipelines?
Answer: Malicious code injection into contracts before deployment, bypassing audit results
A compromised CI/CD pipeline can inject malicious logic into smart contract bytecode after audits are complete, deploying a backdoored contract to the blockchain with no further checks.
