Blockchain Smart Contract and Hyperledger Literacy (Beginner Level)

Topics covered

• compare centralized and distributed ledgers and identify the benefits and drawbacks of each approach
• connect a new node to the private Ethereum network and add it as a peer of the existing node
• connect to an already deployed contract using the Ethereum JavaScript API and invoke its methods
• describe the different blockchain implementations offered by Hyperledger
• describe the motivations of the Hyperledger project and its approach to developing blockchain solutions for enterprises
• develop a test case to list all accessible Ethereum accounts in a private Ethereum network
• enumerate the high-level features of the Solidity programming language
• identify the need for and the features of the Drizzle library to build the UI for a decentralized application (dApp)
• identify the role of the solc compiler and the Remix IDE in building and working with Solidity smart contracts
• interact with a contract deployed on the Rinkeby test network and track the mining of your transactions
• list the characteristics of smart contracts and how they compare with traditional contracts
• list the steps involved in initializing and compiling the smart contracts in a Truffle Project
• list the steps involved in ordering and validating transactions in Hyperledger Fabric
• recall the origins of the Hyperledger project and its approach towards building blockchain solutions
• recall the tools of the Truffle Suite and their individual features
• recognize how the integrity of the blockchain is ensured by cryptographic hashing
• recognize how you can use business-level abstractions to define a blockchain network using Hyperledger Composer
• recognize the properties of Hyperledger Fabric, which have resulted in its adoption by many organizations
• recognize what constitutes a blockchain and how it is used to store a collection of records
• recognize what constitutes a reference type in Solidity and the way such data need to be handled
• script smart contract compilation and define the types of output required, including bytecode and ABI
• use the Geth console to access the various management APIs such as personal, admin, and miner
• use the Metamask client to transfer ether from your account in Metamask to the one in Ethereum Wallet
• use the solc compiler to compile a smart contract to generate Ethereum bytecode
• write the code for a constructor in your smart contract and deploy it to Ethereum
