CBCP Cryptocurrency and Digital Tokens 2 — Questions and Answers
Question 1: Which consensus mechanism does Ethereum currently use after 'The Merge' in 2022?
- Proof of Work
- Proof of Stake (Correct answer)
- Delegated Proof of Stake
- Proof of Authority
Correct answer: Proof of Stake
Ethereum transitioned from Proof of Work to Proof of Stake via 'The Merge' in September 2022, reducing its energy consumption by ~99.95%.
Question 2: What is the primary function of a token's 'vesting schedule' in a cryptocurrency project?
- To determine token price at launch
- To release tokens gradually over time to prevent large sell-offs (Correct answer)
- To calculate staking rewards
- To set the initial token supply
Correct answer: To release tokens gradually over time to prevent large sell-offs
Vesting schedules lock tokens and release them incrementally to align team and investor incentives with long-term project health.
Question 3: What distinguishes a 'security token' from a 'utility token' under US regulatory frameworks?
- Security tokens are always fungible; utility tokens are not
- Security tokens represent ownership or investment interest and are subject to SEC regulation (Correct answer)
- Utility tokens require KYC; security tokens do not
- Security tokens can only be issued on Ethereum
Correct answer: Security tokens represent ownership or investment interest and are subject to SEC regulation
Security tokens pass the Howey Test—representing an investment of money in a common enterprise with expectation of profits—and therefore fall under SEC jurisdiction.
Question 4: In the context of cryptocurrency, what is a 'dust attack'?
- A DDoS attack on blockchain nodes
- Sending tiny amounts of crypto to wallets to track and de-anonymize owners (Correct answer)
- A method of front-running transactions
- Spamming the mempool with low-fee transactions
Correct answer: Sending tiny amounts of crypto to wallets to track and de-anonymize owners
Dust attacks involve sending negligible amounts of cryptocurrency to wallets to analyze transaction patterns and potentially link addresses to real identities.
Question 5: What does 'tokenomics' primarily refer to?
- The technical protocol for token transfers
- The economic design of a token including supply, distribution, and incentive structures (Correct answer)
- The legal framework for token issuance
- The exchange listing process for new tokens
Correct answer: The economic design of a token including supply, distribution, and incentive structures
Tokenomics encompasses all economic aspects of a token: total supply, emission schedule, allocation, burn mechanisms, and how incentives align stakeholders.
Question 6: Which type of cryptocurrency wallet stores private keys on a device not connected to the internet?
- Hot wallet
- Custodial wallet
- Cold wallet (Correct answer)
- Exchange wallet
Correct answer: Cold wallet
Cold wallets (hardware wallets, paper wallets) keep private keys offline, significantly reducing exposure to online hacking threats.
Question 7: What is the purpose of a 'token burn' mechanism in cryptocurrency?
- To penalize validators for double-signing
- To permanently remove tokens from circulation, reducing supply (Correct answer)
- To convert utility tokens into security tokens
- To reset a token's price to its initial value
Correct answer: To permanently remove tokens from circulation, reducing supply
Token burns permanently destroy tokens by sending them to an unspendable address, reducing circulating supply which can create deflationary pressure.
