Solidity is the most popular language on Ethereum, inspired by C++, Python, and JavaScript
Ethereum is an open-source, blockchain-based, decentralized software platform used for its own cryptocurrency, ether. It enables SmartContracts and Distributed Applications (DApps) to be built and run without any downtime, fraud, control, or interference from a third party.

The command sequence to install Hyperledger Fabric v1.0.0-beta:
$ sudo apt-get update
$ sudo apt install libtool libltdl-dev git
$ cd $GOPATH
$ mkdir src
$ cd src
$ mkdir github.com
$ cd github.com
$ mkdir hyperledger
$ cd hyperledger
Download and compile Hyperledger Fabric. You may need to install make by $ sudo apt-get install make in prior to compile the source:
$ git clone https://github.com/hyperledger/fabric.git
$ cd fabric
$ make configtxgen
At the end of make, you can see:
binary available as build/bin/configtxgen``
Subsequently, you can download all docker images by e2e_cli example:
cd examples
cd e2e_cli
chmod +x download-dockerimages.sh
./download-dockerimages.sh
There are the images:
$ docker images

Hyperledger Fabric is intended as a foundation for developing applications or solutions with a modular architecture. Hyperledger Fabric allows components, such as consensus and membership services, to be plug-and-play. Its modular and versatile design satisfies a broad range of industry use cases. It offers a unique approach to a consensus that enables performance at scale while preserving privacy.
Hyperledger Composer is an extensive, open development toolset and framework to make developing blockchain applications easier.
We hope you now know the roadmap to being a professional Blockchain Developer ✌️
