Blockchain Use Case Analysis Flashcards

A pharmaceutical company wants to prevent counterfeit drugs from entering the supply chain. Which blockchain capability is MOST critical for this use case?

Answer: Immutable provenance tracking

Immutable provenance tracking ensures each drug's origin and chain of custody is permanently recorded and tamper-proof, directly combating counterfeiting.

A decentralized energy grid wants consumers to trade excess solar power with neighbors. Which blockchain model best fits peer-to-peer energy trading?

Answer: Public blockchain with token-based micropayments

A public blockchain with token-based micropayments enables trustless, direct peer-to-peer energy transactions without requiring a central intermediary.

When evaluating a blockchain use case for cross-border remittances, which factor most differentiates blockchain from traditional SWIFT transfers?

Answer: Near-instant settlement without correspondent banks

Blockchain enables direct settlement between parties without correspondent banks, dramatically reducing settlement time from days to minutes or seconds.

A government land registry wants to move to blockchain. What is the primary benefit of this transition?

Answer: Elimination of title fraud through immutable ownership records

Immutable ownership records on blockchain prevent fraudulent title transfers, which is the most critical challenge in land registries vulnerable to corruption or tampering.

Which scenario is the WORST fit for blockchain technology?

Answer: Managing a single company's internal employee records with one database admin

A single company's internal records managed by one admin has a single trusted authority, making blockchain's decentralization and overhead unnecessary and counterproductive.

In a trade finance use case, a Letter of Credit is represented as a smart contract. Which benefit does this primarily deliver?

Answer: Automatic document verification and payment release upon condition fulfillment

Smart contract-based Letters of Credit automatically verify shipping documents and release payment when pre-defined conditions are met, removing manual bank processing delays.

A hospital network wants to share patient records across providers while maintaining patient consent. Which architecture element is MOST essential?
