What is Web 3.0 (Web3) – Updated Version of Web 2.0

web 3.0

Web 3.0 is the third generation of technology for the web. It is an improvement over the first two generations. The web, also called the World Wide Web, is the primary layer of the internet that lets websites and applications work.

Web 3.0 is continuously changing and being defined. What is certain is that Web 3.0 will put a lot of attention on decentralized apps and use blockchain-based technology in a big way. Web 3.0 used machine learning and artificial intelligence to make the apps more innovative and flexible.

The idea of a “semantic web,” including Web publisher technologies, is another part of Web 3.0, which is still being defined. Tim Berners-Lee, the founder of the Web, is among many who have urged for the integration of semantic technology into the Web.

It took more than ten years to move from Web 1.0 to Web 2.0, and Web 3.0 is expected to take the same amount of time to implement and reshape the web.

We follow the trend of change from Web 1.0, a static source of information where people read websites but didn’t interact with them much, to Web 2.0, a social and interactive web that makes it easier for people to participate. In that case, Web 3.0 will transform how websites are generated and how people interact.

How Web 3.0 Works

Web 1.0 and Web 2.0 technologies use the Hypertext Markup Language (HTML) to lay out and deliver websites. HTML will still be an essential layer in Web 3.0. Still, the relationship between HTML and data sources and where the data sources are located may be different than in earlier web versions.

In the Web 2.0 era, many websites and apps depend on a central database to store data and make them work. Web 3.0 services and apps use a decentralized blockchain instead of a central database. Blockchain is based on the idea that there is no single, arbitrary authority. Instead, there is a distributed consensus.

The blockchain and Web 3.0 communities are moving toward the idea of a decentralized autonomous organization as a way to run things. Instead of a centralized authority overseeing platform operations, a DAO, Web 3.0 technologies, and communities provide self-governance in an attempt to decentralize.

Web 3.0 is also fundamentally more compatible with cryptocurrencies than conventional currency. Financing and the ability to pay for goods and services with a decentralized payment method are all supported by Web 3.0 through cryptocurrencies, which are all built on top of blockchain technology.

Web 1.0 and Web 2.0 were designed with IPv4 addresses in mind. As a result of the web’s massive development over the decades, there is a demand in Web 3.0 for additional internet addresses, which IPv6 supplies.

Web 3.0 Key Features

Web 3.0 might be built with AI, a semantic web, and omnipresent features in mind. Adopting AI is intended to provide end users with quicker, more relevant information. A website that uses AI should be able to filter through and present the knowledge that it believes a particular user would find helpful. Because the results include websites people have voted on, social bookmarking as a search engine may produce better results than Google. However, these results can be modified by humans. AI could be used to tell the difference between real and fake results, giving results similar to social bookmarking and social media but without negative feedback.

An artificially intelligent web will also include virtual assistants, currently available as features incorporated into devices or third-party applications.

The idea behind the semantic web is to organize and store data in a way that teaches a computer system what each piece of data means. In other words, a website should be able to understand the terms typed into search queries the same way a person would. This would let it create and share better content. AI will also be used in this method. The semantic web will educate a computer on what the data means, and artificial intelligence (AI) will use this knowledge.

Numerous significant Web 3.0 aspects help define what the third generation of the web will likely be all about, including the following:

  • Decentralized: Web 3.0 will not be controlled by a single group. This is different from the first two generations of the web, which a single group mainly controlled. A central server will no longer need to start applications and services elsewhere.
  • Cryptocurrency Enabled: The use of cryptocurrency is a big part of Web 3.0 services, and fiat money has been replaced by cryptocurrency.
  • AI and Autonomous: Web 3.0 is all about automation, and AI will be the main force behind this automation.
  • Blockchain-Based: Blockchain technology enables the development of decentralized apps and services. Data and connections among services are dispersed differently with blockchain than with a centralized database architecture. Blockchain may also offer an immutable log of transactions and activities, which can help establish verifiable authenticity in a decentralized environment.

Web 3.0 Applications

Web 3.0 allows for the existence of an increasing number of innovative apps and services with blockchain at their core, including the following:

  • NFT: Nonfungible tokens (NFTs) are kept on a blockchain with a cryptographic hash, making each token unit unique.
  • dApp: Decentralized apps (dApps) are applications developed on top of the blockchain that employs smart contracts to allow programmatic service delivery that is recorded in an immutable ledger.
  • Cross-Chain Bridges: Cross-chain bridges allow several blockchains to work together in the Web 3.0 environment.
  • Defi: Decentralized finance (DeFi) is a new Web 3.0 use case in which decentralized blockchains provide financial services outside the constraints of traditional centralized banking infrastructure.
  • DAOs: DAOs will organize Web 3.0 services, giving them structure and leadership in a decentralized way.
  • Cryptocurrency: Cryptocurrencies, like Bitcoin, are Web 3.0 apps that try to create a new world of money that is different from the world of fiat currency that existed before.

Differences Between Web 3.0 and Web 2.0

  • Web 3.0 is the successor to the previous two generations of the web.

Tim Berners-Lee created and defined Web 1.0 in 1989. Web 1.0 was all about fundamental access and connectivity across static websites. Tim O’Reilly invented Web 2.0 in 2004, known as the second generation of the Web and a more advanced version of the first generation.

Websites and apps that use user-generated content for end users are referred to as Web 2.0. Many websites currently employ Web 2.0, which emphasizes user participation and cooperation. Web 2.0 also focuses on offering more ubiquitous network access and communication methods.

The difference between Web 2.0 and 3.0 is that Web 3.0 focuses on using technologies such as machine learning and artificial intelligence (AI) to provide appropriate content to each user rather than simply using content supplied by other end users. Web 2.0 lets users contribute to and sometimes work together on on-site content, but Web 3.0 will probably give these jobs to the semantic web and AI technology.

Frequently Asked Questions (FAQs)

What is Web 3.0?

Web 3.0, also called Web 3, is an idea for the next generation of the web, in which most users would be connected through a decentralized network and have access to their data. This article told us about the technologies that will likely improve and change over the next few years.

Is Web 3.0 a blockchain?

Web 3.0 is an idea for a future version of the internet that would be based on public blockchains, a way to keep track of information that is best known for letting people buy and sell bitcoins.

What is the primary goal of Web 3.0?

Web 3.0 is meant to give individuals control and ownership over their data. Web 3.0 is to eliminate the intermediaries, enabling people to provide services to one another and choose whatever parts of the internet they use.

Is Web3 a coding language?

A web3 programming language based on Rust that was initially developed by the Diem Association for use in building on Diem blockchains and is meant to produce safe, intelligent contracts. The Move language was made because the people who made it needed to clarify philosophical contract languages.
