The newest version of the web is called Web3. Web3 comprises decentralized networks constructed on blockchains, as opposed to Web1, which was composed of static web pages, and Web2, which gave us web apps and the web as a platform.
Given that only a tiny percentage of current developers are experts in Web3, there is a high demand for Web3 developers. So, where would you begin if you were an experienced Web2 engineer looking to transition to Web3? What core ideas should you understand, and what tools and technologies should you study?
In this article, we’ll discuss Web3, its significance, and how it differs from Web2. The tech stack aspiring Web3 developers should become familiar with to get started will then be addressed.
Web3 Tech Stack Defining Technologies
How to create a decentralized application (dapp)? The good news is that you can get started with your existing programming knowledge and experience! Since a dapp has a frontend, you’ll need to know HTML, CSS, and JavaScript. You should probably also use frameworks like Angular, React, and Vue. This is excellent news for front-end developers who are already familiar with these technologies.
Let’s examine some of the tools, frameworks, and languages you’ll need to learn specifically for Web3 now:
Writing smart contracts on the Ethereum blockchain requires using Solidity’s programming language. It appears to be a hybrid of JavaScript, Python, and C++. If you’ve mastered a few programming languages, you know it’s simpler. Since most smart contracts involve a financial transaction, adhering to the proper guidelines and security best practices is crucial.
Truffle’s framework makes creating, testing, and implementing smart contracts easier. It is a “development environment, testing framework, and asset pipeline for blockchains using the Ethereum Virtual Machine (EVM),” according to the Truffle website. Similar to how React enables you to create JavaScript applications, Truffle lets you create smart contracts. Truffle is not strictly required, but you should use it because it dramatically simplifies the complexity of development. The Truffle for VS Code extension for VS Code users streamlines the development lifecycle even more.
For the local creation and testing of smart contracts, there is a personal blockchain called Ganache. It allows programmers to launch a local instance of the Ethereum blockchain with a few straightforward commands. Ganache enables you to develop Web3 applications locally, just as you would develop Web2 applications locally or in a test environment as opposed to a production environment.
Web3.js
A JavaScript library called Web3.js is used to communicate with Ethereum. To connect to a user’s wallet, grant access to a smart contract, and call functions on the smart contract, among other things, you would use web3.js in your frontend application. Web3.js enables you to interact with smart contracts from the UI since they can be accessed via the CLI or a UI.
MetaMask
A Web3 wallet called MetaMask is accessible through a browser extension or a mobile application. Wallets have been mentioned before, but their exact nature has not yet been fully established. A wallet provides an interface to your digital assets. With a private key that only you have access to, the contents are protected. Users can safely connect to blockchain-based apps and interact with them using their wallets, thanks to MetaMask. Wallets are necessary for developers to deploy and communicate with smart contracts. The Truffle Dashboard lets you link your MetaMask wallet to your project without disclosing your private keys, which you would generally have to do by including your private keys in your code.
Infura
For connecting to Ethereum and other blockchains and decentralized storage networks like IPFS, Infura is an infrastructure provider. Without going into too much detail, all blockchain interactions necessitate JSON-RPC or WebSocket access to a node. You do not need to spin up your node on your machine because Infura provides the necessary infrastructure. Infura can also be used as a backup if you decide to manage your node. Additionally, Infura offers a development toolkit and suite with features for creating dapps such as monitoring, metrics, logging, transaction management, and other features. To make Web3 development even more straightforward, this is an additional abstraction on top of some of the other technologies we’ve already covered.
Conclusion
The next stage of the internet’s development, Web3, will support the newest software. Blockchains are more transparent technologies that have already gained significant institutional and consumer adoption.
You will have the advantage of breaking into the market if you comprehend what Web3 technology is and how to build it.
I hope by now you feel assured that you’re off to a good start with what you already know, Web3 developers who already have a solid Web2 foundation! You’ll be prepared more quickly than you imagine if you take the time to learn the technologies mentioned above. If you want to start your project, you’d better consult an Enterprise Blockchain Consulting Company in USA.
