What's Web 3.0?

What is the technology of Web 3.0? The latest version of the World Wide Web is called Web 3.0. It is different from earlier versions in that it is less centralized, more useful to consumers, and more open. So, it has the same kind of ability to change things as Web 2.0 has.

Learn more about Web 3.0 and how it might affect your business by reading on. We'll talk about the background of the World Wide Web, the differences between Web 2.0 and Web 3.0, the most important parts of Web 3.0, some Web 3.0 tools and projects, and the computer languages for Web 3.0. We'll talk about whether Web 3.0 is really the future at the end of this book.


How the WWW(World Wide Web) came to be

Before we talk about what Web 3.0 is, let's look at how the World Wide Web came to be:


Web 1.0

Web 1.0 was the first version of the World Wide Web. It ran from 1989 to 2004. Tim Berners-Lee, an English computer scientist who worked at the European Organisation for Nuclear Research (CERN) in 1989, was one of the first people to work on Web 1.0.

Web 1.0, which was also called the "read-only web," was a one-way publishing platform that didn't let users create or change much material. Most people who used the internet just used it to look for information, and only a small number of businesses wrote web pages and material for large audiences. Web 1.0 was meant to show off information, make it easy for people and experts to work together, and give everyone access to material.

Other things that made Web 1.0 what it was were:

  • HTML, URL/URI, and HTTP are the main tools.
  • Tables and frames are HTML 3.2 elements.
  • Sending HTML forms through email
  • Still pages
  • Instead of relational database management systems, websites get their information from the file systems on their computers.
  • Images in GIF format and buttons
  • No ads.

Web 2.0

Web 2.0 is the form of the internet that we use right now. Dale Dougherty, VP of O'Reilly and an early web developer, came up with the term in 2004. Web 2.0 is also called the people-centred web, the knowledge web, and the read/write web.

Web 2.0 has moved towards a more collaborative approach where most web page creators can change their own sites as often as they want. Because of this, information has been going both ways between users and content sources, which has helped the gig economy grow. Web 2.0 has also led to the rise of many ways to engage, such as blogging, social media interaction, shared services, talking, mobile web apps, instant messages, podcasts, weblogs, and sharing pictures. Web 2.0 has also helped Apple, Google, Amazon, Meta (formerly Facebook), and Netflix grow into some of the biggest companies in the world. We even have a shorthand for all of these groups: MAMAA.

The main things that drive the growth of Web 2.0 are web-related tools and standards like:

  • The Cascading Style Sheets (CSS)
  • Extensible HTML (XHTML)
  • DOM stands for Document Object Model.
  • Adobe Flash XSLT/XML Transformations

Web 3.0

In 2014, an English computer scientist named Gavin Wood came up with the word "Web 3.0." Tim Berners-Lee came up with the name "semantic web," and Web3 is another name for the idea.

Web 3.0 is a plan for the internet's future that makes it less centralized and more open than it is now. No single family of service providers will host services. Instead, everyone will use algorithms to run sites. Imagine a blockchain for the whole internet. Web 3.0 also wants to make it easier to build multiple web apps and make it easier to find services or goods without having to do a lot of work by hand.

Some examples of Web 3.0 technologies are:

  • Resource Description Framework (RDF) and RDF Schema (RDFS)
  • RDF data can be queried using Web Ontology Language (OWL), RDF Query Language (SPARQL), and the Simple Protocol.
  • Digital currency and cryptocurrency—in fact, Web 3.0 may work better with cryptocurrency than with traditional currency.
  • Uses for the blockchain
  • IT on the edge
  • Non-fungible tokens (NFTs)
  • Networks with no central hub

The metaverse is a shared digital world where people can build businesses, make connections, and talk to each other in real time. Virtual reality (VR) goggles and other devices can be used to get into the metaverse.

Describe Web 3.0. Even though there isn't a single, agreed-upon description of Web 3.0, all ideas about it share the following traits:


Decentralisation

In Web 2.0, computers use HTTP as unique web names to find information saved on centralized servers at set locations. But in Web 3.0, information is not centralized, so it can be saved in more than one place at the same time. This would get rid of the huge files that web giants like Google and Meta are currently in charge of, giving users full power over their contacts and data.


Artificial Intelligence

AI (artificial intelligence) will be a key part of Web 3.0. Popular AI is already being used by Web 2.0 apps like Netflix and Amazon to improve the user experience and make suggestions. Web 3.0 might take this a step further by making suggestions based on user data that are even more specific.


Learning by Machine

Because of machine learning, in Web 3.0, computers will be able to handle data in the same way that people do. Machine learning is a part of AI that tries to imitate how people learn by using algorithms and smart search engines. Machine learning will give computers the ability to produce more relevant and faster results in many fields, such as the creation of new materials and drugs.


Permissionless and trustless

Not only will Web 3.0 be decentralized, but it will also be permissionless and trustless. This means that anyone can join, even without permission from ruling bodies, and that networks will let people talk to each other directly without going through a trusted third party. We can expect Web 3.0 apps to run on peer-to-peer networks, blockchains, or a combination of the two.


Ubiquity

In Web 3.0, information and material will be easier to find and will be linked to more places. In other words, many apps, like those for Internet of Things (IoT) devices like smart thermostats, refrigerators, cars, lights, and other gadgets, can access the same information.


Web 3.0 examples

Now that you know what Web 3.0 is, here are two of the most popular Web 3.0 apps and technologies:


Non-Fungible Tokens

A non-fungible token (NFT) is a digital signature that is unique and can't be changed, copied, or split up. NFTs are written down on a blockchain, which is used to prove the item's title and its realness. NFTs can be sold or traded between users to change who owns them.

NFTs are easy to make because you don't need to know much or any code to make them. Most NFTs point to pictures or drawings, but they can also point to movies or audio recordings.

Here are some well-known NFTs:

  • Grimes' digital art, some of which has sold for more than $6 million, includes a moving GIF of Nyan Cat, a 2011 meme in which a cat made of Pop-Tarts flies.
  • Bids reached $2.5 million for the first ever tweet.
  • Sorare's NFT trade cards for football

Decentralized Finances (DeFi)

Decentralized finance (DeFi) is a new financial environment that is built on blockchain technology. It is made up of different public peer-to-peer blockchain banking services, mostly Ethereum.

 DeFi serves two main goals:

  • Test centralized financial systems like banks and brokerages.
  • Allow people to share digital information with each other.

Unlike standard banking systems, DeFi does not charge people for using its services. Users can also store money in safe digital wallets and send money to other people in a matter of seconds.


Web 3.0 Programming Languages

As Web 3.0 grows in popularity, the number of people looking for Web 3.0 web and app writers has increased.

 If you want to hire Web 3.0 writers, here are the most popular computer languages for Web 3.0:


Solidity

Solidity is a high-level, object-oriented programming language for making smart contracts on Ethereum and other blockchain networks.

Smart contracts are programmes that run when certain conditions are met. These programmes are stored on blockchains. Smart contracts are used by Web 3.0 writers to control, execute, or record actions or events instantly based on the rules of an agreement or contract. They can, for example, use Solidity to make contracts for donations, voting, digital wallets with multiple signatures, and secret bids.


Python

Python is a language that is based on objects and is read out loud. It works with different ways of writing, such as functional, organized, and object-oriented.

Python can help Web 3.0 writers build and test their programmes very quickly. The language is also easy to learn, which speeds up the process of coming up with new ideas.


Java

Java is an object-oriented, class-based language that is often used to make apps for Android phones. It is often used to make websites.

Java can be used by Web 3.0 writers to make smart contracts with a lot of tools, direct memory cleaning, and support for object-oriented programming. A lot of programmers, like those who made Hyperledger Fabric, have used Java to make blockchain systems.


C++

C++ is one of the most popular computer languages right now. It is used in GUIs, operating systems, and embedded systems. The biggest benefit of writing in C++ is that it is easy to handle memory. So, the makers of Web 3.0 can use C++ to combine data and methods into a single package.


HTML

In Web 3.0, HTML is also a very important language. HTML is the standard code language for arranging web content. Since the 1990s, it has been an important part of Web 2.0 apps. Without it, programmers and artists wouldn't be able to describe and organize paragraphs and headers on web pages and apps.

In Web 3.0, HTML is likely to have the same functions. In particular, we can expect programmers and artists to keep making web pages and apps with HTML. They will probably also use HTML to insert movies and pictures on different sites.


Vyper

Vyper is a bright and simple alternative to Solidity. It is similar to Python in many much ways. It gets rid of problems like loops that never end, repeated calls, and modifiers. Vyper, on the other hand, isn't done like the other languages on this list. Once it is done, though, Web 3.0 coders can use it to make smart contracts that work well.


Rust

Rust is an open-source computer language that is strictly typed and covers many programming concepts. The language is both safe and effective. It has a nice interpreter with helpful error messages, great instructions, and top-notch tools, such as:

  • A build tool and package manager that work together
  • Smart support for multiple editors with type checks and autocompletion
  • An auto-formatter for Web 3.0 can use rust to increase speed by getting rid of various bug classes. By controlling low-level features, they can also use them to make software that is safe.


Golang

Three Google experts created Golang, also known as "Go." It is a written and compiled programming language with a grammar like C.

Go is one of the best computer languages for Web 3.0 because it has trash collection, structured typing, concurrency based on communicating sequential processes (CSP), and memory safety. It is easy to learn, like Python, which cuts down on programming time. Big businesses like Uber, Netflix, and American Express have used Go to create scalable and clean apps.


Web 3.0 is going really well.

New technology trends show that Web 3.0 is the way of the future.

First of all, from 2019 to 2025, the blockchain market grew at a huge compound annual growth rate (CAGR) of nearly 70%. This is because blockchain has many benefits, such as getting rid of accounting, lowering the need to keep duplicate records, and making transaction confirmation more reliable.

NFTs have also become well-known. When NFTs were first brought to people's attention in 2020, most of the people who made them were unknown digital artists and singers. But as NFTs became more famous in 2021 and 2022, Disney and other global media companies started putting out NFT sets.

Also, collaborative things like the metaverse are expected to become more important in our lives. Gartner says that by 2026, 25% of people will spend at least an hour in the metaverse. A study by the consulting firm McKinsey also showed that tech companies, private equity, and venture capitalists invested around $120 billion in the first half of 2022.
