Read the first 7 Solution Architecture Design flashcards as text

  1. A blockchain architect is designing a supply chain solution where multiple competing companies must share data. Which architecture pattern best preserves data confidentiality between competitors?

    Answer: Consortium blockchain with private channels

    Consortium blockchains with private channels (like Hyperledger Fabric's channels) allow competing organizations to share a network while keeping sensitive data visible only to authorized parties.

  2. When designing a blockchain solution for high-frequency trading, which factor most critically impacts transaction finality?

    Answer: Consensus mechanism latency

    Consensus mechanism latency directly determines how quickly a transaction achieves finality; PoW can take minutes while BFT-based consensus can achieve finality in seconds.

  3. An architect needs to design a blockchain solution that stores medical records. The solution must comply with HIPAA's right-to-erasure provisions. What is the recommended approach?

    Answer: Store PII off-chain with only hashes on-chain

    Storing personally identifiable information off-chain with only cryptographic hashes on-chain allows deletion of sensitive data while preserving the integrity proof on the immutable ledger.

  4. Which design pattern is most appropriate when a blockchain solution needs to integrate with multiple legacy enterprise systems that use different data formats?

    Answer: Oracle network with data transformation layer

    An oracle network with a data transformation layer acts as a bridge that translates heterogeneous legacy data formats into a canonical format before writing to the blockchain.

  5. A CBSA candidate is evaluating blockchain platforms for a solution requiring 10,000+ TPS with sub-second finality. Which platform architecture best fits this requirement?

    Answer: Algorand or similar pure PoS with pipelined consensus

    Pure Proof-of-Stake platforms with pipelined consensus (like Algorand) are designed to achieve thousands of TPS with near-instant finality without off-chain layer-2 solutions.

  6. In a multi-cloud blockchain deployment, which architectural consideration is most critical for ensuring node synchronization consistency?

    Answer: Network latency and clock synchronization across regions

    Network latency and clock synchronization (NTP/PTP) are critical because consensus protocols rely on message ordering and timing; inconsistencies cause forks or failed consensus rounds.

  7. What is the primary architectural advantage of using a state channel pattern in a blockchain solution?

    Answer: Enables off-chain transactions with on-chain settlement

    State channels allow parties to conduct numerous transactions off-chain at high speed and low cost, only settling the final state on-chain, dramatically improving throughput and reducing fees.
