Start building your first DApps to reinforce your understanding of blockchain development. Now you have successfully deployed your smart contract on the blockchain. Problem is that the only way to interact with it is using the command line.

A typical web application, like Uber or Twitter, runs on a computer system owned and managed by a company, allowing that company complete control over the app and how it functions. On one side, there may be several users, but only one company controls the backend. Solidity is a high-level, object-oriented language that can be used to construct smart contracts.

Launch the Blockchain App

Smart contracts cover a large part of blockchain development. However, it is not wise to learn smart contracts in isolation. One mistake that most newbies make is to dive straight into smart contracts without having a technical background in web development. Blockchain technologies are built on top of web technologies and so before you get deep into blockchain development you need to understand the fundamental concepts of web development.

In the design of the DAPP, there will be two main challenges; first, the integration with the blockchain, and secondly the integration with the wallet. For integration with the blockchain, we shall make use of a JavaScript library called Web3.js, which is quite easy and help can be found online. In simpler terms, a smart contract is a program that lives on top of the blockchain and constitutes a set of rules agreed upon by the involved parties. Learning a framework would enable you to build a dynamic user interface quite quickly though that’s optional if you have the patience to build everything from scratch. For a suitable framework, it is recommended that you learn “react”, which is a JavaScript-based framework.
