Hyperledger Interview Questions and Answers – Set 1

0

This is the first in series of practice tests / interview questions and answers in relation to Hyperledger products suite for building distributed ledgers / Blockchain business networks. This test focuses on checking your knowledge on different products such as following under hyperledger umbrella.

  • Fabric
  • Sawtooth
  • Iroha
  • Indy
  • Burrow
  • Cello
  • Composer
  • Quilt
  • Explorer



Revision Notes – Hyperledger Tools & Frameworks

  • Hyperledger Fabric supports pluggable consensus algorithm (ordering service) and membership service provider
  • Hyperledger Indy can be used to build distributed ledger (Blockchain) related with decentralized digital identities
  • Hyperledger Burrow is used for creating a permissioned Ethereum smart-contract blockchain node that executes smart contract code following the Ethereum specification.
  • Hyperledger Explorer can be used to view, invoke, deploy or query blocks, transactions and associated data, network information (name, status, list of nodes) etc.
  • Hyperledger Sawtooth can be used to build enterprise blockchain networks with focus on scalability (PoET) and security (transaction families)
  • Hyperledger Iroha simple, lightweight blockchain framework for creation and management of assets in infrastructural projects.
  • Hyperledger Composer is an application development framework (ADF) for building blockchain business networks.
  • Hyperledger Quilt can be used to achieve interoperability across Blockchain networks. It is based on inter-ledger protocol.
  • Hyperledger Cello can be used to create Blockchain-as-a-service platform to provision a customizable Blockchain networks.
