CBSA Blockchain Use Case Analysis 5

Question 1

A real estate company wants to tokenize properties so investors can buy fractional ownership. What regulatory challenge is MOST likely to arise in the US?

Accepted Answer

SEC classification of property tokens as securities requiring registration and disclosure

Answer

In the US, fractional ownership tokens likely qualify as securities under the Howey Test, requiring SEC registration or a valid exemption before they can be offered to investors.

Question 2

A logistics company asks you to compare blockchain versus a traditional EDI system for sharing shipping documents. What is the MOST accurate statement?

Accepted Answer

EDI is suitable for bilateral trusted partners, while blockchain adds value when multiple untrusting parties share data

Answer

EDI is efficient for established bilateral relationships, but blockchain's shared ledger and consensus mechanism become advantageous when many untrusting parties must synchronize documents without a central hub.

Question 3

An architect is evaluating whether to use on-chain or off-chain storage for a use case involving large medical imaging files (MRI scans). What is the recommended approach?

Accepted Answer

Store images off-chain and record only cryptographic hashes on-chain

Answer

Storing only the cryptographic hash on-chain preserves verifiability and integrity guarantees while keeping large files in cost-efficient off-chain storage like IPFS or encrypted cloud storage.

Question 4

Which supply chain use case benefits MOST from blockchain's multi-party visibility feature rather than its immutability feature?

Accepted Answer

Enabling multiple customs agencies, freight forwarders, and shippers to see the same document status in real time

Answer

Real-time shared visibility of document status across multiple organizations in different countries is a coordination problem that blockchain's shared ledger solves independently of its immutability.

Question 5

A DeFi protocol wants to offer collateralized loans where smart contracts automatically liquidate positions when collateral falls below a threshold. What critical dependency must the architect address?

Accepted Answer

Reliable and manipulation-resistant price oracle feeds to trigger liquidations accurately

Answer

Liquidation logic depends entirely on accurate asset prices fed by oracles; a manipulated or faulty price feed can cause unjust liquidations or prevent necessary ones, threatening protocol solvency.
