The web is constantly evolving and changing. With the release of new browsers and updates to existing ones, developers can create more innovative and interactive websites.

Web3 is the future of the internet. It refers to developing applications that use blockchain technology and semantic web technologies.

These applications will be able to interact with each other and with devices like smartphones and cars. Web 3 development is the next step in the evolution of the web. It takes advantage of new technologies that allow greater interactivity and a more user-friendly experience.

This type of development is made possible by the increasing availability of artificial intelligence and Internet of Things (IoT) devices.

History of the Web

The web is a technology that has revolutionized the way humans interact and share information. It has its roots in the military, where researchers were looking for a way to keep troops connected during combat with the ARPANET.

Then later, the web was a way for researchers at universities and science labs to share information.

In the early days, the web was primarily used for academic purposes. It wasn't until the mid-90s that the web began to be used for commercial purposes.

The first website, info.cern.ch, was created by British scientist Tim Berners-Lee on August 6, 1989-1991, and the site consisted of a few pages about the World Wide Web project and its use.

In 1993, CERN made the source code for the website available to the public domain.

In 1994, Netscape Communications Corporation released the first commercial web browser, Netscape Navigator. The release of Navigator led to widespread use of the web.

In 1995, Microsoft released Internet Explorer, and the battle between Netscape and Microsoft began. These days, Internet Explorer is no longer popular, but AOL eventually bought out Netscape.

Amazon became the first large e-commerce site to go online. Other early e-commerce sites include eBay and Yahoo! Shopping.

In 1997-98, Google was founded by Larry Page and Sergey Brin while they were both Ph.D. students at Stanford University.

The 2000s saw the rise of social media websites like Facebook and Twitter.

10 Things You Didn't Realize Were Invented in the 2000s

Web usage continued to grow in the early 21st century. Many people were using the web for communication, shopping, and entertainment. The web continued to grow in popularity and had become a mainstream technology.

WEB 101

The web is an information system that connects computers around the world. It allows people to share information and access data from anywhere. The web consists of sites and pages of information accessed using a web browser.

A website can be created by anyone with a computer and an internet connection. Websites can store information, sell products, or communicate with others.

Here is a list with a short description of web 1.0, web 2.0, and web 3.0: 

Web 1.0 was all about static websites with text and images. There was very little interactivity or user engagement. Instead, you would use a search engine to find what you were looking for and then click on links to other websites.

Web 2.0 ushered in the age of social media, blogs, wikis, and RSS feed. Users could now share content and collaborate on projects online. For example, you can post comments on websites, share photos and videos, and collaborate with others online.

Web 3.0 is all about the internet of things (IoT), Blockchain, and Artificial Intelligence. With billions of devices connected to the internet, we can now interact with the world around us in ways never before possible.

Websites are now more like applications than pages of text, and users can share their experiences through social media.

Evolution Web 1.0, Web 2.0 to Web 3.0

The next stage of the web is already starting to take shape. Web 3.0 will be based on the Internet of Things, which will allow devices to communicate with each other independently. This will enable a more decentralized internet where users have more control over their data.

What is web3?

The Web3 is an umbrella term for a proposed new version of the World Wide Web. It has been referred to as "the third web" (along with the first web of websites and the second web of social media), "Web 3.0", "the semantic web," and "the intelligent web."

What Is the Semantic Web?

The idea behind Web3 is to create a more intelligent and user-friendly internet by developing protocols that allow machines to share data seamlessly.

This would be done by making the web's underlying architecture more transparent and user-friendly while incorporating more sophisticated search capabilities with Blockchain and artificial intelligence.

It should provide a more secure and decentralized internet that would be more user-friendly and less reliant on centralized authorities.

These applications include decentralized exchanges, peer-to-peer payments, and online voting.
Web3 should increase security, privacy protection, and a user-friendly interface.

This should lead to a more democratic internet where users have more control over their information.

Web3 is still in its early stages of development, but there are already a number of projects underway that aim to bring this new version of the internet to fruition.

What is Web3 development?

In short, it is the use of blockchain technology and artificial semantic intelligence to create smarter, more user-friendly websites. By harnessing the power of these cutting-edge technologies, web3 developers can create websites that are more secure, efficient, and intuitive.

Web3 development includes building applications that use blockchain technology and decentralized networks. It enables you to create trustless transactions and apps that are censorship-resistant. This makes it a perfect choice for projects that need to be reliable and secure.

To develop in this way, you need to understand the basics of blockchain technology and how it works.

You also need to be familiar with the different types of decentralized networks and how they function. Once you have a basic understanding of these things, you can start building your Web3 applications.

What do you need to get started?

If you are looking to get started with web3 development, there are a few things you will need to learn.

The first is the basics of blockchain technology and how it works. You will also need to understand the Ethereum platform and how to use it to create DApps.

Many online resources can help you learn these skills, so don't be afraid to get started. With a bit of time and effort, you can become a web3 developer and join the exciting world of blockchain technology.

Another option is to join a community of Web3 developers. This can provide you with support and guidance as you learn more about this exciting new field.

There are also many online forums where you can ask questions and share your ideas with other developers.

Finally, you will need to learn some basic programming skills to write code for your DApps.

Blockchain 101

Blockchain technology is a digital ledger of all cryptocurrency transactions. It is constantly growing as "completed" blocks are added with a new set of recordings.

Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.

Bitcoin nodes use the blockchain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.

Blockchain technology creates an unchangeable, transparent, and tamper-proof record of all cryptocurrency transactions.

This is done by distributing the ledger across a network of computers rather than storing it centrally. This process also helps to ensure that all transactions are verified and approved by the network before they are added to the blockchain.

Ethereum 101

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third-party interference. The Ether token powers Ethereum.

To understand Ethereum, you need first to understand blockchain technology. Blockchain is a distributed database that allows for secure, transparent, and tamper-proof transactions.

Transactions are verified by network nodes through cryptography and recorded in a public ledger. This ledger is known as the blockchain. Ethereum builds on blockchain technology by adding smart contract functionality.

Ethereum Applications and tools

Developers need to use Solidity's programming language to create, deploy, and use smart contracts on the ethereum blockchain. 

A number of applications and tools have been developed for the ethereum blockchain that makes it easier for developers to create and deploy smart contracts and DAPPS. 

When it comes to blockchain technology, a few key concepts must be understood to use the technology.

These applications and tools include Truffle, Remix, Metamask, and Ethfiddle.

Truffle is a popular development framework for Ethereum that helps developers build contracts, deploy them, and test them. It also provides built-in smart contract compilation, linking, deployment, and testing capabilities.

Remix is a browser-based IDE for Ethereum that allows developers to write and debug contracts. It also features a solidity editor with autocompletion and syntax highlighting.

Metamask is a popular Ethereum wallet that allows users to interact with Dapps on the web. It supports multiple currencies and has a user-friendly interface.

Ethfiddle is one such tool that has been created to help developers create and test their Dapps. Ethfiddle is a code editor that allows users to write and execute Solidity code in an online environment. It also includes a library of functions, contracts, and examples.

There are a number of applications and tools that can be used to create or interact with smart contracts.

Together, these tools make it easier for developers to create Ethereum applications. As the blockchain ecosystem grows, these tools will play a key role in its development.

What are Smart Contracts?

A Smart Contract is a computer protocol intended to digitally facilitate, verify, or enforce the negotiation or performance.

Smart contracts allow the performance of credible transactions without third parties. Furthermore, these transactions are trackable and irreversible.

Introduction to smart contracts | ethereum.org

Nick Szabo first proposed smart contracts in 1994. He described them as: "a contract that will execute itself."

Nick Szabo -- The Idea of Smart Contracts

Bitcoin implemented the first application of a smart contract in 2009 to verify and automate the exchange of bitcoins between two parties.

Smart contracts are written in code and run on a blockchain network. They are self-executing, meaning that once the contract conditions are met, the contract will automatically execute.

This eliminates third-party intermediaries such as lawyers or notaries to verify or enforce the contract.

Solidity 101

Solidity is a high-level programming language for developing smart contracts on the Ethereum platform. It is designed to target the Ethereum Virtual Machine (EVM). C++, Python, and JavaScript influenced solidity.

As a result, it has a syntax similar to that of JavaScript, and it is intended to be easy to learn for people familiar with JavaScript.

Solidity is a programming language for writing smart contracts on the Ethereum blockchain. It is a contract-oriented, high-level language whose syntax is similar to that of JavaScript.

Solidity was designed to target the Ethereum Virtual Machine (EVM), executing smart contracts.

When you write a Solidity program, your computer first compiles it into bytecode that the EVM can understand. This bytecode is then run on one or more nodes in the Ethereum network, and the result is stored in a blockchain database.

What are Decentralized Applications Apps (Dapps)?

When most people think of applications, they think of software that runs on their personal computer or phone.

However, with the advent of web3 and blockchain technology, a new type of application has emerged- decentralized applications, or Dapps.

Dapps are built on the blockchain and use its features to create a more decentralized internet.

This means that they are not controlled by anyone entity- instead, they are run by the users themselves. Because of this, Dapps can be much more trustless and secure than traditional applications.

Another key feature of Dapps is that they are often open-source, meaning that anyone can view the code that makes them work.

This allows for greater transparency and accountability and gives developers the ability to learn from each other's work.

The Web3 Developer Stack 

The Web3 Developer Stack is a set of tools used to build web3 projects and apps. It includes a variety of software development tools, libraries, and frameworks. As a result, the stack is a powerful toolkit for web3 developers.

The most popular web3 development stack comprises the following libraries: Web3.js, Ethers.js, Parity, Geth, Embark, IPFS, and Ganache.

Web3.js is a JavaScript library that allows developers to interact with the Ethereum blockchain.

Ethers.js is a library for creating Ethereum-based tokens. 

Parity is a web3 development framework and Dapp browser. It is written in Rust and uses the WASM virtual machine. Parity provides developers with an easy way to create and deploy Dapps.

Geth is a popular command-line interface for running Ethereum nodes and developing Dapps. Geth is written in Go, and it supports all the features of the Ethereum network, including smart contracts, state transitions, and mining. Geth also includes a built-in JavaScript console that allows you to interact with the blockchain directly.

Embark is a web development framework that uses blockchain technology and the Ethereum network to create decentralized applications or Dapps. It was created in 2014 by Jarrad Hope and Lenny Hyde, who were looking for a way to make it easier for developers to create Dapps.

IPFS (InterPlanetary File System) is a distributed file system that seeks to connect all computing devices with the same system. It is built on top of blockchain technology and uses peer-to-peer networking to enable users to share files without the need for a central server. IPFS can be used to develop decentralized applications (Dapps) and is seen as a key component of the web3 ecosystem.

Ganache is a powerful development tool that makes it easy to create and test decentralized applications (Dapps). It provides a blockchain network for developers to deploy their Dapps and includes a built-in wallet for storing ether and tokens. Ganache also includes features for testing smart contracts, such as invoking methods and simulating transactions.

Many other components make up the web3 developer stack. These include web browsers, block explorers, wallets, and mining software. Each of these components plays an important role in developing and using Dapps.
