Read the first 7 Enterprise Blockchain Platforms flashcards as text

  1. In Hyperledger Fabric, what distinguishes 'chaincode' from traditional smart contracts on public blockchains?

    Answer: Chaincode is executed in a sandboxed Docker container and can be written in multiple languages

    Hyperledger Fabric chaincode runs inside Docker containers and supports languages like Go, Java, and Node.js, unlike most public blockchain smart contracts limited to a single language.

  2. Which enterprise blockchain platform uses the concept of 'CorDapps' as its application layer?

    Answer: R3 Corda

    CorDapps (Corda Distributed Applications) are the application layer on R3 Corda that define flows, states, and contracts for specific business processes.

  3. What is the key privacy advantage of R3 Corda compared to traditional blockchain networks?

    Answer: Transaction data is shared only with parties directly involved in the transaction

    Corda's architecture shares transaction data only with the parties directly involved, unlike most blockchains that broadcast data to all participants.

  4. In an enterprise blockchain deployment, what does 'BFT' stand for and why is it significant?

    Answer: Byzantine Fault Tolerance, ensuring the network operates correctly even with malicious nodes

    Byzantine Fault Tolerance (BFT) ensures a blockchain network can reach consensus even if some nodes behave maliciously, which is critical for untrusted multi-party enterprise networks.

  5. Which Hyperledger project provides a distributed ledger framework specifically designed for identity management and verifiable credentials?

    Answer: Hyperledger Indy

    Hyperledger Indy is purpose-built for decentralized identity, providing tools for creating and using independent digital identities rooted on blockchain.

  6. What is the primary function of the 'World State' database in Hyperledger Fabric?

    Answer: Storing the current value of all ledger assets for fast query access

    The World State in Hyperledger Fabric stores the current snapshot of all asset values, enabling efficient queries without replaying the entire transaction history.

  7. In enterprise blockchain contexts, what is a 'consortium blockchain'?

    Answer: A partially decentralized network governed by a group of pre-selected organizations

    A consortium blockchain is governed by a group of pre-selected organizations rather than a single entity or the general public, balancing decentralization with control.
