Best 3 Courses to Learn Web3 Development for Free

Often called the ‘Future of the Internet’, Web3 offers a read/write/own version of the web – which is blockchain-based – and includes cryptocurrencies, NFTs, DAOs, decentralised finance, and more. Web3’s vision is to rewire or rearrange how the web works. The use of blockchain tech is instrumental in actualising the vision and changing the ways of storage, sharing, and ownership of information.

Web3 development is gaining significant traction in the market as many experts believe it has the potential to create new economies, product classes, and online services, breaking away the existing monopolies that a few corporations command over the internet and information in more general terms.

What is Web3 Development?

As a development platform, Web3 allows developers to build decentralised applications (dApps) that run on a network of nodes which are not controlled by a single entity. The use of blockchain tech in Web3 development is to create an open, transparent, and secure transaction system.

Distributable ledgers and the immutable recording of data on the blockchain remove the need for third-party verification of transactions and give birth to a trustless, secure system, which is ideal for use in financial services, supply chain management, and several other industries.

Developers build dApps on Web3 using known languages like JavaScript or Solidity and several more. There are also several tools to debug and test applications.

Importance of Learning Web3 Development

According to the Electric Capital Developer Report (January – December 2021), there were more than 18,000 monthly active developers committing code in open-source crypto and Web3 projects in 2021. While 65% of active developers in Web3 joined in 2021, 45% of full-time developers in Web3 joined in 2021.

This surge of developers in Web3 development is largely driven by the benefits Web3 brings to the ecosystem. Developers have realised the value they can leverage in the virtual world by developing on Web3.

Web3 applications are immune to autocratic censorship without them having to compromise security. The use of cryptography ensures that the data that has been used is protected from tampering and unauthorised access. Self-executing smart contracts that work as the backbone for developing dApps do not depend on time-consuming and cost-bearing intermediaries. This advantage makes Web3 more efficient and cost-effective. Built-in features like Ethereum and Truffle make Web3 conducive to developers to formulate high-quality dApps.

How Do You Learn Web3 Development for Free?

Naturally, developers who want to build effective and efficient applications to solve a multitude of problems, service bottlenecks, and process deficiencies around them would like to leverage the latest technology paradigm out there. Traditional internet developers would have to learn Web3 development skills to be able to participate in this. Students of application development would also prefer to learn these skills.

All of these come to the essential question of how to learn Web3 development. Here, we present the best three courses for one to learn Web3 development for free.

Free Courses for Web3 Development

The course has been split into four consequentially progressive steps. It starts with the module Freshman, meant to teach the basics of Web3. The next module is Sophomore, where users learn to dig deeper and build dApps. The third is Junior, which helps the learner get embedded in the ecosystem, and the fourth is Senior, where one learns about Web3 security and hacking.

Course content overview: The course content of the Freshman module includes Basic Programming, Solidity Concepts, ways to build a simple get/set dApp, cryptocurrency, simple NFT, and more. The Sophomore module teaches how to build whitelist dApps, NFT collection, ICO, on-chain NFT investment DAO, etc. The Junior module includes details on Layer 2, setting up local nodes with Hardhat, contract verification on Etherscan, IPFS deep-dive, etc. Finally, the Senior Module is about the Ethereum World State and EVM Execution, upgradable smart contracts, gas optimisations, meta transactions, etc.
