web2 vs. web3: What is the difference?

Have you ever heard about Web3 and wondered what it means? Are you wondering how it’s different from the current internet? You came to the right place.

The internet has changed a lot over the years, from the simple websites of the early days to the interactive and social platforms we use today. Web2 is what we’re familiar with now—social media, videos, and apps run by big companies. But a new version of the internet, called Web3, is emerging, and it’s all about giving you more control over your data and online activities.

In this article, we’ll explore how the internet has evolved from Web1 to Web2, and now to Web3. We’ll break down the key differences between Web2 and Web3, explain the main ideas behind Web3, and look at both the benefits and challenges it brings. By the end, you’ll understand what Web3 is, why it matters, and how it could shape the future of the internet.

The evolution of the web can be seen in three main phases: Web 1.0, Web 2.0, and Web 3.0. Each phase brought new technologies and changed how you interact with the internet. Below are real-world examples to show how the web has transformed over time.

Web 1.0 (Read-only)

Web 1.0, often called the “read-only” web, was the first stage of the internet from the early 1990s to the early 2000s. This era featured static web pages with little to no interaction. Websites were like digital brochures, where you could only read the information without contributing or engaging with the content.

For example, Yahoo Directory was a categorized list of websites. You could browse it to find information, but there was no option to interact with the content or create your own.

Web 2.0 (Interactive, Social Web)

Web 2.0, starting in the mid-2000s, marked a major shift toward interaction and user-generated content. This phase, often referred to as the “social web,” allowed you to create, share, and engage with content across various platforms.

For example, Facebook lets you create a profile, post updates, and connect with friends. However, the data you share is controlled by Facebook. Other examples include:

• YouTube: You can upload videos, watch others’ content, and leave comments.
• Wikipedia: You can contribute to articles and edit them alongside other users.
• Instagram: You can share photos and videos, but the platform owns and manages the data.

Web 3.0 (Decentralized Web)

Web 3.0 is the next step in the evolution of the internet. This phase is all about giving you more control over your data and online experiences. Instead of relying on big companies to manage everything, Web3 uses technology like blockchain to decentralize control, meaning you have ownership of your data.

Some examples include:

• Filecoin: A storage network where you can rent out extra space on your computer or store your own files without needing companies like Google or Dropbox.

• Brave Browser: A browser that protects your privacy by blocking ads and trackers. If you choose to see ads, you get paid directly in cryptocurrency, putting control in your hands.

Takeaway:

• Web 1.0: The early version of the web where you could only read information (e.g., Yahoo Directory).
• Web 2.0: The internet as we know it today, where you can create and share content, but big companies control your data (e.g., Facebook).
• Web 3.0: The future of the internet, where you own and control your data using blockchain technology (e.g., Filecoin, Brave Browser).

Web2 and Web3 represent two different stages of the internet. In Web2, large companies control platforms and your data, while Web3 is decentralized, giving you more control over your information. With blockchain technology, Web3 allows you to interact directly with others, providing better privacy and transparency. The table below highlights the main differences between Web2 and Web3-

Web3 is built on ideas that put you at the center of the internet, setting it apart from Web2. These principles shape Web3 into a more secure, user-driven experience, empowering you to take control rather than relying on big corporations. Some of the key ideas include:

• Decentralization - With Web3, you don’t have to rely on a few big companies to control your data and platforms. Instead, power is spread across a network of users like you. This decentralized system is more secure, eliminating single points of failure and ensuring no one entity can dominate the web, making it fairer for everyone involved.

• Verifiability - Web3’s transparency ensures that you can trust the system because everything runs on blockchain technology. Every transaction and action can be independently verified by you or anyone else. This guarantees that the system operates fairly without needing a central authority to oversee it. 

• Permissionless- In Web3, you can freely join and participate without needing approval from any company or authority. Unlike Web2, where access is controlled, Web3 is open to everyone, including you. This freedom means you can create, innovate, and share without any barriers holding you back. 

• Self-governance - Web3 platforms are governed by users like you. Decisions about updates or changes are made through community voting, giving you a say in how the system evolves. The power shifts from corporations to the hands of the people, ensuring you can help shape the future of the platforms you use.

• Ownership - One of the most exciting aspects of Web3 is that you finally own your data and digital assets. With blockchain technology, you control your cryptocurrencies, NFTs, and any other digital property without relying on third parties. This gives you complete ownership and control over what’s yours. 

In Web3, you are empowered with full control over your data, assets, and online experience, making the internet a place where you hold the keys.

Web3 offers many benefits that make it stand out from the current web, creating a more secure, fair, and user-focused experience. Here are some of the key benefits you get:

• RResilient to breakdowns and censorship - Web3 is built on decentralized networks, so there’s no single point of failure. If part of the network goes down, the rest keeps running smoothly. This means Web3 is much harder for governments or corporations to shut down, giving you a more reliable experience. 

• Censorship resistant -  In Web2, companies or governments can block content or control access. With Web3’s decentralized structure, it’s almost impossible for anyone to censor content or decide what you can or cannot see, giving you more freedom. 

• Democratized access to finance - Web3 provides you with open access to financial services through decentralized finance (DeFi). This means you can borrow, lend, and trade without needing a bank or middleman, empowering more people to participate in the global economy.

• Better governance - Web3 platforms give you the power to vote on changes and updates. This makes governance more democratic, as decisions are made by the community rather than a central authority. You have more influence over how the platform operates.

• Identity management - Instead of relying on companies to manage your online identity like in Web2, Web3 allows you to control your identity. You can decide how and when to share your information, reducing the risk of data misuse or leaks.

• Security - Web3 offers better security because it’s based on blockchain technology, which uses cryptography to protect data. This makes it harder for hackers to tamper with or steal your information, providing a safer environment.

• Tokenization and Incentives - Web3 uses tokens (like cryptocurrencies) to reward you and create new digital assets. You can earn, trade, or use tokens as part of the platform’s ecosystem, opening up new economic opportunities for you.

• Interoperability - Web3 is designed for seamless interaction between different platforms. You can move your data, assets, and tokens across various applications without restrictions, creating a more connected and flexible online experience for you.

While Web3 brings many exciting benefits, it also comes with challenges that you should be aware of. Here are some key limitations:

• Regulation - Because Web3 operates in a decentralized way, it’s difficult for governments to regulate. This can create legal uncertainty, making it unclear what rules apply. As Web3 grows, finding the right balance between decentralization and regulation will be important for users. 

• Premature User Experience -  Web3 is still developing, and the user experience can be tricky for beginners. Setting up wallets, using decentralized apps (dApps), or managing digital assets can feel confusing compared to the ease of Web2 platforms. As the technology improves, these processes should become more user-friendly.

• Scalability - As more people join Web3, handling a large number of transactions can be slow and expensive during busy times. While solutions like Layer 2 and sharding are being developed to improve scalability, they aren’t yet as efficient as Web2 platforms. .

• Environmental Concerns - Certain Web3 technologies, particularly those using proof-of-work consensus (like Bitcoin), consume a lot of energy. This raises environmental concerns. However, many platforms are moving towards more eco-friendly options, like proof-of-stake, to reduce energy use.

• Security Challenges - Even though Web3 is decentralized, security risks still exist. Hacks, smart contract bugs, and phishing attacks are common. You need to be extra cautious when protecting your digital assets, which can be a steep learning curve if you’re new to the space.

While Web3 brings many exciting benefits, it also comes with challenges that you should be aware of. Here are some key limitations:

• Decentralized Finance (DeFi) - One of the most popular use cases of Web3 is DeFi. Platforms like Uniswap, Aave, and Compound allow you to trade, lend, and borrow cryptocurrencies without needing a bank. These services are open to anyone, giving you more financial freedom and control over your assets.

• Non-Fungible Tokens (NFTs) -  NFTs are a major part of Web3, representing ownership of unique digital assets like art, music, or virtual real estate. Platforms like OpenSea and Rarible let you buy, sell, and trade digital collectibles, while artists and creators can earn directly from their work without intermediaries.

• Decentralized Autonomous Organizations (DAOs) - DAOs are blockchain-based groups where members vote on decisions. For example, MakerDAO governs the DAI stablecoin. DAOs allow you to participate in managing projects in a transparent and democratic way without needing a traditional company structure.

• Supply Chain Management - Web3 is improving transparency in supply chains. Companies use blockchain to track goods from their origin to the consumer. IBM’s Food Trust blockchain, for instance, helps track food products, ensuring safety and authenticity.

• Gaming and the Metaverse - Web3 is revolutionizing gaming by giving you true ownership of in-game items. Games like Axie Infinity and Decentraland allow you to earn cryptocurrencies and own virtual land and items, creating new economic opportunities in the gaming space.

• Identity Management - Web3 allows you to take control of your digital identity. Platforms like Civic and uPort let you securely manage your personal information, giving you the power to decide what data to share with different services, without relying on a central authority.
