The third generation of the internet or Web3 is the next evolutionary phase of the connected world. It is all about democratizing the conventional internet with a far more data-driven, secure, and privacy-focused approach using technologies such as Blockchain & Artificial Intelligence. In simple terms, web3 can be defined as: “An Internet of the people, by the people, for the people”.

So how do you go about becoming a web3 developer? In this blog post, we’ve put together an extensive list of resources and concepts to learn for kickstarting your journey in the world of web3. Read on.

Prerequisites 📔

Learn Web development and add HTML, CSS, JavaScript, React/Angular/Vue to your skill set.HTML: https://www.w3schools.com/html/CSS: https://developer.mozilla.org/en-US/docs/Learn/CSS/First_stepsHTML & CSS Crash Course: https://scrimba.com/learn/htmlcssJavascript: https://developer.mozilla.org/en-US/docs/Web/JavaScriptReactJs: https://reactjs.org/tutorial/tutorial.html

Now that you are good with the basics of Web development it’s time to know the secret of “keeping secrets secret” i.e Cryptography.

Cryptography 🔐

The most important and fundamental necessity for constructing a blockchain is cryptography. Cryptography is a means of protecting sensitive data against unwanted access. Cryptographic techniques are used as part of security procedures on the blockchain.

Fundamentals of Blockchain💡

Blockchain is a digital ledger that records all transactions that occur in a peer-to-peer network. All data transported over Blockchain is encrypted, and each occurrence is recorded, ensuring that the data cannot be changed.

What Is Distributed Ledger Technology (DLT)?https://www.investopedia.com/terms/d/distributed-ledger-technology-dlt.asp

Ethereum 📒

Ethereum is a decentralized blockchain technology and a P2P network for securely executing and verifying application code known as smart contracts. Smart contracts enable users to transact with one another without the need for a trustworthy centralized system. Records are unchangeable, verifiable, and safely distributed over the network, providing participants with complete ownership and insight into transaction data.

User-created Ethereum accounts can send and receive transactions. As a cost of executing transactions on the network, a user must spend ETH (Ethereum’s native currency) to sign the transaction.

Smart Contracts 🤝

Smart contracts are essentially code that run when certain criteria are satisfied and are recorded on a blockchain. They are typically used to automate the implementation of a deal so that all users are instantly confident of the result, without the participation of an intermediary and the subsequent time that it occupies. Smart contracts also let you automate a process by initiating the next operation when certain circumstances are satisfied.

DApp Development 💻

So, first and foremost, a decentralized application, or DApp, is an online program that operates on a decentralized P2P network. DApps are utilized in most functional ways in the same manner as any other software programme and therefore can be built as a website or as a mobile application.
