Hyperledger Fabric 2.x - First Practical Blockchain [2022]

Install prerequisites on Ubuntu Linux for deploying Hyperledger Fabric, following the official Composer documentation, and use Docker containers to streamline setup while avoiding Windows.

Install the Mac prerequisites for Hyperledger Fabric by setting up Xcode command line tools and nvm. Then install the latest LTS node and the Mac Docker installer.

Execute commands to set up development environment, including npm and the command line interface, install generator and human packages, and use the composer playground to scaffold a dummy business network.

Set up a local Hyperledger Fabric 2.x development environment by downloading fabric tools, installing the runtime, and starting docker containers to run and test networks.

Start a local composer playground to deploy a business network on fabric, define ledger entities and activities, and connect to a locally hosted network while troubleshooting startup issues.

Define a model with assets, participants, and transactions; create a commodity asset with a trading symbol as its primary key, a creator participant, and a transaction that records ownership transfer.

Define the business logic of transactions in javascript for hyperledger fabric 2.x, creating a mortgage function that updates asset ownership through the registry with async operations.

Create participants and assets, execute a commodity transfer, and observe how each transaction is recorded on the block chain ledger with a transaction id in a sandbox.

Create and deploy a Hyperledger Fabric business network by scaffolding a composer project, defining assets, participants, and trades, then expose a REST API via explorer.

Explore the composer rest server and loopback interface to interact with the fabric ledger via rest by creating commodities and creators and executing get, post, and delete operations.

Learn to access a Hyperledger Fabric 2.x network from outside the local environment using a third-party REST client like Postman or Insomnia, performing get and post requests to manage commodities.

Build a PHP-based REST client to interact with a Hyperledger Fabric blockchain, creating assets, participants, and transactions, and exposing a server for app access.

Prepare a clean Ubuntu 20.04 environment with bash, install git and jq, configure docker to start on boot, and set up Norges 12.x and npm 6.x for Fabric prerequisites.

Download and install Hyperledger Fabric binaries, set up a two-organization network with peers and an auditor, deploy a basic chaincode, and configure a Node.js client to connect.

Publish and interact with a smart contract in Hyperledger Fabric 2.x by building JavaScript chaincode for asset transfer and deploying it to two organizations through install, approve, and commit.

Interact with the smart contract via command line to invoke the init ledger function, monitor blockchain logs, and perform read operations to view assets on the channel.

clean the environment by removing all docker containers, images, volumes, and fabric samples to start from scratch. proceed to avoid deleting non-fabric resources as you prepare for node-based blockchain work.

Learn to access Hyperledger Fabric chaincode programmatically with a clean Node.js application, using helper functions to load config, build wallets, and enroll admins and users via the CA.

Set up a node-based asset app for Fabric, install Fabric client and network, create wallets and identities, and register admin and non-admin users to interact with the smart contract.

Interact with ledger using gateway, connection profile, wallet, and discovery to submit or evaluate chaincode transactions. Learn to get all assets, read assets, and create assets via a rest API.
