Read the first 7 Enterprise Blockchain Platforms flashcards as text

  1. What is the role of 'Anchor Peers' in Hyperledger Fabric's gossip protocol?

    Answer: They serve as reference points enabling cross-organization peer discovery within a channel

    Anchor Peers are designated peers within an organization that facilitate cross-organizational peer discovery through Fabric's gossip data dissemination protocol.

  2. Which consensus algorithm used in some enterprise blockchains requires nodes to prove computational effort to earn the right to validate transactions?

    Answer: Proof of Work

    Proof of Work requires nodes to perform computationally expensive hash calculations, but it is generally considered too energy-intensive and slow for enterprise blockchain deployments.

  3. In Hyperledger Besu, what does 'IBFT 2.0' refer to?

    Answer: Istanbul Byzantine Fault Tolerant consensus, version 2.0

    IBFT 2.0 (Istanbul Byzantine Fault Tolerant) is a consensus algorithm in Hyperledger Besu designed for private Ethereum networks, offering immediate transaction finality.

  4. What is the significance of 'Private Data Collections' in Hyperledger Fabric?

    Answer: They enable specific subsets of channel members to keep data confidential from other channel members

    Private Data Collections allow a subset of organizations within a channel to endorse, commit, and query private data that other channel members cannot access.

  5. Which enterprise blockchain platform uses the concept of 'Flows' to orchestrate multi-party business processes?

    Answer: R3 Corda with CorDapp Flows

    R3 Corda uses Flows as a framework for writing multi-party business processes that coordinate communication and state transitions between Corda nodes.

  6. What is 'Proof of Authority' (PoA) consensus and where is it commonly used in enterprise blockchain?

    Answer: A consensus where pre-approved validators take turns creating blocks; used in private enterprise networks

    Proof of Authority uses a set of pre-approved, known validators who take turns or are elected to produce blocks, offering high throughput suitable for enterprise private networks.

  7. In enterprise blockchain deployments, what does 'TPS' measure and why is it critical for platform selection?

    Answer: Transactions Per Second — a measure of network throughput and scalability

    Transactions Per Second (TPS) measures how many transactions a blockchain can process per second, a key metric for evaluating whether a platform can handle enterprise workload volumes.
