CFP Blockchain & Cryptocurrency Integration 3 — Questions and Answers
Question 1: A fintech company integrating crypto payments must comply with FinCEN's Travel Rule. What does this rule require?
- All crypto transactions must travel through a licensed exchange
- Transmitters must share sender and recipient information for transfers above $3,000 (Correct answer)
- Cryptocurrency must travel through at least two jurisdictions before settlement
- All on-chain transactions must include geographic routing data
Correct answer: Transmitters must share sender and recipient information for transfers above $3,000
FinCEN's Travel Rule requires financial institutions to pass along certain customer information when transferring funds over $3,000, now extended to virtual asset transfers.
Question 2: Which type of blockchain architecture would a consortium of banks most likely use for an interbank settlement platform?
- Public permissionless blockchain like Bitcoin
- Private permissioned blockchain with known validators (Correct answer)
- A fully centralized private database with no cryptographic proofs
- A proof-of-work sidechain anchored to Ethereum
Correct answer: Private permissioned blockchain with known validators
Consortium or private permissioned blockchains allow known institutions to control validator access while retaining distributed ledger benefits like immutability and auditability.
Question 3: What is 'impermanent loss' in the context of DeFi liquidity provision?
- Permanent loss caused by smart contract exploits draining a liquidity pool
- The temporary reduction in value a liquidity provider experiences compared to simply holding assets (Correct answer)
- Interest income lost due to pool fee rate cuts
- A tax penalty assessed when withdrawing from a DeFi protocol early
Correct answer: The temporary reduction in value a liquidity provider experiences compared to simply holding assets
Impermanent loss occurs when the price ratio of pooled assets changes after deposit, meaning the LP would have been better off holding the assets rather than providing liquidity.
Question 4: Under US tax law, how does the IRS classify cryptocurrency received as payment for services?
- Non-taxable digital barter that avoids income reporting
- Ordinary income at fair market value on the date received (Correct answer)
- Capital gain taxed at long-term rates regardless of holding period
- Foreign currency income exempt from self-employment tax
Correct answer: Ordinary income at fair market value on the date received
The IRS treats crypto received for services as ordinary income equal to the fair market value in USD on the receipt date, subject to income and self-employment taxes.
Question 5: What is the purpose of a blockchain oracle in smart contract applications?
- To store encrypted user credentials on-chain
- To provide external real-world data to smart contracts that cannot access it natively (Correct answer)
- To audit and certify smart contract code before deployment
- To generate random numbers used in cryptographic key creation
Correct answer: To provide external real-world data to smart contracts that cannot access it natively
Oracles bridge the gap between blockchain smart contracts and external data sources (prices, weather, events) since blockchains cannot natively access off-chain information.
Question 6: A fintech startup is considering issuing a utility token to raise capital. Under the Howey Test, the token would be classified as a security if it:
- Is transferred over a public blockchain network
- Represents an investment of money in a common enterprise with expectation of profit from others' efforts (Correct answer)
- Is denominated in USD and pegged 1:1 to fiat currency
- Can be redeemed for goods or services within the issuer's platform
Correct answer: Represents an investment of money in a common enterprise with expectation of profit from others' efforts
The Howey Test classifies an asset as a security if there is an investment of money in a common enterprise with an expectation of profit derived from others' efforts.
Question 7: What distinguishes a 'hot wallet' from a 'cold wallet' in cryptocurrency custody?
- Hot wallets use faster blockchain networks; cold wallets use slower networks
- Hot wallets are connected to the internet; cold wallets are kept offline for security (Correct answer)
- Hot wallets hold only Bitcoin; cold wallets hold all other cryptocurrencies
- Hot wallets are custodial; cold wallets are always non-custodial
Correct answer: Hot wallets are connected to the internet; cold wallets are kept offline for security
Hot wallets are internet-connected and convenient for frequent transactions but more vulnerable to hacks; cold wallets are offline, offering greater security for long-term storage.
