Blockchain Technology Use Cases 3 — Questions and Answers
Question 1: How do non-fungible tokens (NFTs) extend beyond digital art into gaming use cases?
- They prevent players from trading in-game items
- They give players verifiable ownership of in-game assets transferable across platforms (Correct answer)
- They replace game servers with blockchain nodes
- They make all games free to play permanently
Correct answer: They give players verifiable ownership of in-game assets transferable across platforms
NFTs represent unique in-game items on a blockchain, letting players truly own, sell, or transfer assets outside the game publisher's control.
Question 2: Which U.S. government application uses blockchain to enhance transparency in federal grant disbursement?
- Federal Reserve monetary policy
- USAID pilot projects tracking humanitarian aid flows (Correct answer)
- IRS income tax collection
- Social Security benefit calculations
Correct answer: USAID pilot projects tracking humanitarian aid flows
USAID and similar agencies have piloted blockchain to trace humanitarian aid disbursements, reducing fraud and increasing accountability.
Question 3: In trade finance, what document is most commonly digitized on blockchain to reduce fraud?
- Letter of credit (Correct answer)
- Employee payroll slip
- Marketing invoice
- Consumer credit score
Correct answer: Letter of credit
Letters of credit are high-value documents prone to fraud; blockchain digitization creates a single, tamper-evident version visible to all parties.
Question 4: A pharmaceutical company uses blockchain to track drugs from manufacturer to pharmacy. What problem does this primarily solve?
- Reducing marketing costs
- Detecting and removing counterfeit drugs from the supply chain (Correct answer)
- Automating drug discovery research
- Replacing FDA regulatory approval
Correct answer: Detecting and removing counterfeit drugs from the supply chain
Each drug batch's movement is logged on-chain, making it easy to identify when and where a counterfeit or diverted product entered the chain.
Question 5: What is a key advantage of using blockchain for voting systems in US elections?
- It eliminates the need for voter registration entirely
- It provides an auditable, tamper-resistant record of cast votes (Correct answer)
- It automatically counts votes faster than any current system
- It allows anonymous vote selling
Correct answer: It provides an auditable, tamper-resistant record of cast votes
A blockchain voting system creates an immutable audit trail where every cast vote can be verified without revealing the voter's identity.
Question 6: How does a decentralized autonomous organization (DAO) use blockchain in its governance?
- A CEO approves all decisions off-chain
- Token holders vote on proposals and smart contracts execute approved decisions automatically (Correct answer)
- The government appoints board members
- Shareholders meet physically to vote
Correct answer: Token holders vote on proposals and smart contracts execute approved decisions automatically
DAOs encode governance rules in smart contracts; token holders vote on-chain and winning proposals are executed automatically without human intermediaries.
Question 7: Which blockchain use case specifically addresses the problem of academic credential fraud?
- Tokenizing university endowment funds
- Issuing tamper-proof digital diplomas verifiable by employers (Correct answer)
- Mining cryptocurrency to fund scholarships
- Creating NFTs of campus artwork
Correct answer: Issuing tamper-proof digital diplomas verifiable by employers
Universities issue blockchain-anchored diplomas that employers can verify instantly, making fake credentials trivially detectable.
