Read the first 7 Enterprise Blockchain Platforms flashcards as text

  1. Which enterprise blockchain platform was built by the Linux Foundation and supports multiple programming languages for smart contract development including Go, JavaScript, and Java?

    Answer: Hyperledger Fabric

    Hyperledger Fabric, maintained under the Linux Foundation's Hyperledger umbrella, supports chaincode written in Go, JavaScript (Node.js), and Java.

  2. What is the main architectural difference between Hyperledger Fabric's 'execute-order-validate' model and traditional blockchain's 'order-execute' model?

    Answer: Fabric simulates and endorses transactions before ordering, enabling parallel execution and early conflict detection

    Fabric's execute-order-validate model allows peers to simulate transactions in parallel and endorse results before ordering, detecting read-write conflicts early and improving throughput.

  3. In the context of enterprise blockchain platforms, what is a 'sidechain'?

    Answer: A separate blockchain that runs parallel to a main chain and is interoperable with it via a two-way peg

    A sidechain is an independent blockchain that operates in parallel to a main chain, connected via a two-way peg that allows assets to move between the chains.

  4. What is the purpose of the 'Endorsement Policy' in Hyperledger Fabric?

    Answer: It specifies which organizations' peers must sign a transaction for it to be considered valid

    Endorsement policies in Hyperledger Fabric define which combination of organizations must execute and sign a transaction proposal for it to be accepted as valid.

  5. Which enterprise blockchain deployment model allows organizations to use blockchain-as-a-service without managing the underlying infrastructure?

    Answer: Cloud-hosted BaaS (Blockchain as a Service)

    BaaS (Blockchain as a Service) offerings from providers like IBM, Azure, and AWS allow enterprises to deploy blockchain networks without managing servers, networking, or node software.

  6. In Hyperledger Fabric, what is the 'Orderer' service responsible for?

    Answer: Establishing consensus on transaction order and cutting blocks for distribution to peers

    The Orderer service in Hyperledger Fabric is responsible for reaching consensus on transaction ordering and packaging ordered transactions into blocks for distribution to channel peers.

  7. What is the primary use case that differentiates Hyperledger Sawtooth from other enterprise blockchain platforms?

    Answer: It uses Proof of Elapsed Time (PoET) consensus and supports parallel transaction execution via transaction families

    Hyperledger Sawtooth is distinguished by its Proof of Elapsed Time (PoET) consensus using Intel SGX hardware and its parallel transaction execution model through pluggable transaction families.
