Which CBSE domain covers the security requirements for running and hardening blockchain node software in production environments?
Answer: Node and Infrastructure Security
Node and Infrastructure Security addresses OS hardening, firewall configuration, RPC endpoint protection, and secure node deployment practices for blockchain validators and full nodes.
A CBSE candidate is asked about Sybil attacks. What is the core mechanism of a Sybil attack on a blockchain network?
Answer: Creating many fake identities or nodes to gain disproportionate influence
A Sybil attack involves an adversary creating multiple fake node identities to dominate voting, routing, or data dissemination in a peer-to-peer network.
The CBSE exam tests knowledge of zero-knowledge proofs (ZKPs). What is the primary privacy benefit ZKPs offer in blockchain transactions?
Answer: They allow a party to prove knowledge of a value without revealing the value itself
Zero-knowledge proofs enable a prover to convince a verifier that a statement is true (e.g., 'I have sufficient funds') without disclosing the underlying secret data.
In the CBSE curriculum, which regulatory framework is most relevant when assessing compliance obligations for a US-based blockchain security professional?
Answer: BSA/AML and FinCEN guidance
The Bank Secrecy Act (BSA) and FinCEN guidance form the primary US regulatory framework for Anti-Money Laundering (AML) compliance relevant to blockchain and cryptocurrency businesses.
Which CBSE topic addresses the security of Proof-of-Stake validator key management, particularly slashing conditions?
Answer: Validator Key and Slashing Security
Validator Key and Slashing Security covers the risk that a validator's signing key could be used to double-sign blocks, triggering slashing penalties and loss of staked funds.
A CBSE exam scenario involves a transaction malleability vulnerability. What does transaction malleability allow an attacker to alter?
Answer: The transaction ID (TXID) without changing its fundamental economic content
Transaction malleability allows an attacker to modify the transaction's signature data, changing the TXID while keeping the inputs, outputs, and amounts identical, which can confuse systems that track by TXID.
The CBSE curriculum includes governance security. What attack specifically targets on-chain governance systems by accumulating voting tokens to push malicious proposals?
Answer: Governance takeover / governance attack
A governance attack (or governance takeover) occurs when an adversary acquires enough governance tokens to unilaterally pass malicious protocol changes, as seen in the Beanstalk DeFi hack.
