Web3 Developer Roadmap by Arcana Network

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_steps
HTML & CSS Crash Course: https://scrimba.com/learn/htmlcss
Javascript: https://developer.mozilla.org/en-US/docs/Web/JavaScript
ReactJs: 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.

Web3.0 or Decentralized web might be an opportunity to reclaim control of our data from the major tech companies. So, how does it operate, and when can we expect it?

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.

Solidity is an object-oriented, high-level language for implementing smart contracts.

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.

What are DApps and how are they useful?
