What is Web 3.0 & Why Does It Matter?

Summary: Web 3.0 is here, and experts proclaim it as a pivotal shift from the internet we know today. Businesses and leaders are exploring the potential of what could transform the digital landscape with the ‘read/write/own’ web shift. As the foundation of the present-day Web dynamics changes, let’s look at what Web 3.0 is, why it matters, and how it could shape the future of your business. Read on to explore and understand more.

The early 2000s were the darkest years in the history of the Internet. Many online companies went out of business, and many others lost a significant portion of their market capitalization. For example, Cisco was an $80.06 stock in March 2000 but was reduced to only $8.6 by October 2002. The media, too, at that time, talked only about the Internet being a passing craze.

Internet is just a fad

Only 48% of dot com companies survived the disaster, and these were those that didn’t give up and saw an opportunity in the crisis. Today, the same organizations rule the world and control a significant portion of the Internet. Google, Amazon, and Microsoft are prominent examples.

A similar narrative ran around Web 3.0 last year. While some called Web 3.0 the future of the Internet, others felt quite the opposite, as these tweets from Elon Musk and Jack Dorsey indicate.

So, what is Web 3.0, and why is there so much fuss around it? Is it just a fad or a next step into the evolution of the Internet? If it’s the next phase of the Internet, how can your business benefit from it? Read on to find out:

What is Web 3.0?

Web 3.0 is the next generation of the Internet. It is secure, decentralized, and free from the control of the Internet and social media organizations. This version of the Internet is based on blockchain technology and operates on token-based economics.

The idea behind Web 3.0 is to create an internet that accurately interprets your input, understands what you convey, and allows complete control over what type of content you want to consume.

An Overview of Web 3.0 Stack

Shifting from Web 2.0 to Web 3.0 has minimal impact on end-users but involves radical changes at the backend. The technology stack for Web 3.0 will be different.

Here’s what it would look like:

the web3 stack

1. Network Layer

The network layer is the lowest in the Web 3.0 stack. Contrary to Web 2.0, which relies on centralized databases, Web 3.0 will be powered by blockchain for trustless and permissionless access.

To choose a blockchain network for building decentralized applications (dApps), developers will have two options:

A. Ethereum Virtual Machine (EVM) Blockchain

An Ethereum blockchain-powered virtual machine stores critical information like accounts, balances, and machine states.

EVM Blockchain Examples

  • Ethereum – Original EVM intelligent contract platform
  • Polygon – Ethereum sidechain
  • Arbitron – Layer 2 blockchain using Optimistic rollups and multi-round fraud proofs
  • Optimism – Layer 2 blockchain using Optimistic rollups and single-round fraud proofs
  • Hermez – ZK rollup Ethereum Layer 2 network managed by Polygon
  • ZKSync – ZK rollup Ethereum Layer 2 network using SNARKs
  • Starknet – ZK rollup Ethereum Layer 2 network using STARKs
  • Avalanche – EVM-compatible Layer 1
  • Cronos – EVM-compatible Layer 1

B. Non-EVM Blockchains

These blockchains don’t follow the Ethereum framework and are created by engineers who feel that EVM chains are too limited by the Ethereum framework.

Non-EVM Blockchain Examples

  • Flow – Layer 1 using Cadence, Flow’s native resource-oriented programming language
  • NEAR – Layer 1 using Rust or Assembly Script for intelligent contracts
  • Solana – Layer 1 using Rust C and C++ for smart contracts
  • Terra – Layer 1 using Rust for smart contracts

2. Blockchain Interaction Layer

The blockchain interaction layer allows developers and users to read and write data to the blockchain. Data providers, like block explorers, are a vital part of this layer. They serve as an online resource for retrieving real-time and historical data about transactions, address balances, gas fees, etc. Thus, the public can easily read and interpret blockchains.

3. Presentation Layer

This layer of the Web 3.0 stack contains high-level abstractions and frontend libraries, and it mirrors many aspects of Web 2.0 development.

4. Application Layer

The application layer contains customer interfaces for accessing Web 3.0. It ranges across Defi, NFTs, Identity & Authentication, Data & Analytics, and many other exciting dApp categories. The public consumers will interact with this layer to access Web 3.0.

Besides these four layers, Web 3.0 uses InterPlanetary File System (IPFS), a peer-to-peer hypermedia protocol. It makes storing and sharing files on the distributed web easy by using content-addressing to uniquely identify each file in a global namespace connecting all computing devices. Experts proclaim it as the future of internet protocols.

It is the Web 3.0 technology stack as of now. As the technology grows, we’ll see more infrastructure tools and paradigm shifts. While the stack will change, these Web 3.0 layers will stay.

Web 2.0 vs. Web 3.0: What’s the Difference?

web 2.0 vs web 3.0

While Web 2.0 and Web 3.0 have a similar origin, both intend to solve the same purpose, i.e., offering the best experience to anyone accessing the Internet. Web 2.0 focuses on reading and writing content. On the other hand, Web 3.0 focuses on the essence. However, these two differences are just the tip of the iceberg. As you dig further, there’s a lot more:

Web 2.0
Web 3.0
Focus Web 2.0 primarily focuses on community development. Empowering individual users is the primary focus of Web 3.0.
Content Presentation Web 2.0 uses cookies to track users and offer personalized experiences. Web 3.0 uses NFTs to assign value and offer some kind of perks.
Content Ownership Data is owned and controlled by centralized authorities who use it the way they want. Data is owned and controlled by the individual who created it.
Technologies CSS3, HTML5, Ajax, and JavaScript are prominent technologies in Web 2.0. Artificial intelligence, machine learning, and decentralized protocols will rule Web 3.0.
Types of Applications Podcast, video streaming, communication, and content creation platforms are prominent in Web 2.0. Web 3.0 will have a majority of AI and ML-powered apps (dApps) such as 3D portals, integrated games, and multi-user virtual environments.

Benefits of Web 3.0 for Businesses

1. End to the Monopoly of Tech Giants

Only a handful of organizations own and control the user-generated data. Not only do they exploit it at their will, but they also sell it to third-party service providers to earn revenue and influence user behavior.

Web 3.0 will end the data monopoly and centralized platforms that control users’ data. Decentralization will take center stage, and the complete data control will be in users’ hands. They will have the power to decide what data they want to share with businesses and earn money.

Even better, single centralized entities will not control Web 3.0, and the Internet will be a place owned and shared by everyone.

2. Fewer Intermediaries

In Web 2.0, many third parties are involved, between customers and companies. When customers purchase a product or service from a company, revenue gets shared with these intermediaries.

Web 3.0 directly connects companies with customers. No longer do they have to share their earnings with third parties. The need for monitoring transactions for fairness will still be there, but such authorities will be few.

3. Increased Security & Privacy

Website Security is the biggest issue for businesses in Web 2.0. Now and then, we hear of websites getting hacked and users’ data getting stolen. These incidents often cost millions, and let’s not forget the damage they cause to their reputation.

Web 3.0 will put an end to such instances. Data breaches and privacy hacks will become minimal, with privacy and security getting priority. Also, since Web 3.0 is decentralized, it will be impossible for hackers to breach the network without being traced.

4. Streamlined Business Operations

In Web 2.0, businesses spend most of their time streamlining their operations, which takes a massive chunk of their time and effort.

With Web 3.0, businesses can create and manage processes without much effort. With smart contracts, they can easily maintain a transaction ledger for everyone involved. For example, run a hotel business. You can access real-time information about guests, invoices, and bookings and offer personalized services to each guest based on their previous purchases and preferences.

5. Higher Transparency

One of the significant drawbacks of Web 2.0 is that it lacks transparency. Users hardly know what organizations do with their data. Although each organization lists its terms and conditions on its website, they’re so complex that they all barely understand them. It often leads to a lack of trust between businesses and customers.

Web 3.0 offers higher transparency

Web 3.0 is a massive step towards ensuring transparency. Businesses can maintain transparency by sustaining an unchangeable record of transactions on the blockchain and making it visible to everyone. They can also become more accountable as it is possible to track each transaction.

Here’s how this will help:

  • Users will have to spend less time researching products or services.
  • There will be less involvement of third parties and increased trust as everything will be in front of their eyes.

Web 3.0 Challenges that Businesses Might Face

  • Web 3.0 will put great pressure on businesses to modernize. They will be forced to modernize and enhance their websites to ensure they don’t lose their captured market.
  • As Web 3.0 is relatively new, it will be a learning curve for companies engaged in web development services. They will need time and practice to get the hang of the technology.
  • The decentralized nature of Web 3 will make it difficult to monitor and regulate it. Strong privacy policies will be needed to avoid the misuse of data.

How can Your Business Invest in Web 3.0?

Every technological revolution brings some fresh opportunities. Web 1.0 paved the way for companies like Amazon and Google, who saw an opportunity in online services. Web 2.0 cleared a path for companies like Facebook and TikTok that revolutionized the way people interact with each other.

Now, you might wonder What opportunities does Web 3.0 bring onboard? How can my business be a part of the Web 3.0 moment? If so, this section is for you. Here’s how your business can invest in Web 3.0:

1. Social Media

We already have social media platforms like Facebook, Instagram, Twitter, and LinkedIn. However, they are all censored and controlled by centralized organizations, limiting the freedom of expression.

That’s when Web 3.0 offers an opportunity to build something that takes control from centralized organizations and brings it back to end-users. You can create a decentralized platform where no one can spin the narrative or misuse data – and everyone has the freedom of saying what they feel.

2. Currency Exchange Services

Existing currency exchange services are not safe from cyber threats. As we saw in the Mt Gox hack, around $460 million worth of bitcoins were hacked. Hence, it is crucial to create a decentralized currency exchange service where people can trade without worrying about cybercriminals. With Web 3.0, you can build such a platform.

3. Messaging Platforms

The Internet is full of adverse reports about the existing messaging platforms. They have highlighted two major issues that these apps suffer from.

  • Unsafe transmission of messages.
  • Reliability of centralized solutions prone to hacking and data misuse.

You can create messaging apps like YSign or Obsidian that operate on blockchain technology to maintain privacy and security. By giving people such a messaging platform, you can build an app that becomes popular on an even grander scale than WhatsApp or Telegram.

4. Data Storage Solutions

Most data storage services we use today, like Google Drive and OneDrive, are centralized. It means the organization managing it has control over this data. They can use it however they want or sell it to third-party advertisers. Sometimes, these storage solutions can be breached and fall into the wrong hands.

You can leverage Web 3.0 to build decentralized data storage solutions. You can create a platform that first encrypts the data and shares it through a peer-to-peer network. As a result, the data will not be stored in one place but on multiple nodes – making it foolproof against manipulations and cyber attacks.

5. Streaming Services

We have platforms like Netflix and Spotify that rule the media streaming space. However, they are often accused of misusing the audience data for advertisement purposes and not paying creators enough. Then, there are copyright issues that tarnish the reputation of these platforms.
By leveraging the Web 3.0 technologies, you can build a decentralized platform that leverages smart contracts to ensure transparency with creators and content consumers. Also, there will be no copyright issues because of these contracts.

6. Web Browsers

Google Chrome and Mozilla Firefox currently rule the Web 2.0 space. However, we often hear reports of security breaches and data misuse.

It leads to the need for the next generation of web browsers powered with Web 3.0 and can protect users’ data without misusing it or even earn some bucks if they share their data with you. By building such web browsers, you can create something that offers users a better alternative than existing options.
