How to Set Up a Private Blockchain Network using Hyperledger Fabric

Hyperledger Fabric is an open-source blockchain framework that provides a modular architecture for developing enterprise-grade distributed ledger applications. It was created by the Linux Foundation’s Hyperledger project and is designed to address the needs of businesses that require a flexible, scalable, and secure platform for Hyperledger application development.


Using a plug-and-play design, Hyperledger Fabric is a platform for building enterprise-grade blockchain networks. Hyperledger Fabric uses Distributed Ledger Technology (DLT) to build a permissioned blockchain system. Unlike other platforms that require non-standard or domain-specific languages, it is the first platform where smart contracts can be created in general-purpose programming languages like Java, Go, and Node.js.


Hyperledger Fabric, in contrast to most blockchains, is permissioned. This implies logically that since the participants are not anonymous, it is impossible to fully trust them. In essence, the network can be governed by a framework for handling disputes that are based on the confidence between participants.

In this developer’s guide, we will explore how to set up a private blockchain network on Hyperledger Fabric. The test network will utilize two nodes to demonstrate the setup.


Setting up a Private Test Network


To run a Docker-based fabric test network these are the prerequisites:


1. Install the latest version of git if it is not already installed.

$ sudo apt-get install git

2. Install the latest version of cURL if it is not already installed.

$ sudo apt-get install curl

3. Install the latest version of Docker if it is not already installed.

$ sudo apt-get install -y install docker-compose


Install Fabric and Fabric Samples


$ curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh && chmod +x install-fabric.sh

$ ./install-fabric.sh docker samples binary


Run the Fabric Test Network


1. Clone Fabric Samples git repo

$ git clone https://github.com/hyperledger/fabric-samples.git

2. Go to fabric-samples/test-network

$ cd fabric-samples/test-network

3. Start the test network

$ ./network.sh up

It will produce the following output

Creating network “fabric_test” with the default driver

Creating volume “net_orderer.example.com” with default driver

Creating volume “net_peer0.org1.example.com” with default driver

Creating volume “net_peer0.org2.example.com” with default driver

Creating peer0.org2.example.com … done

Creating orderer.example.com … done

Creating peer0.org1.example.com … done

Creating cli … done

The Components of the Test Network


$ docker ps -a
