What is Web3? and how it is different from the Web2 we know today

The internet has seen several transformative phases since its inception, and one of the most intriguing and recent developments is the emergence of Web3. In this article, we’ll explore what is web3 and how it is different from the web2 we know today. Web3 is a concept that represents a fundamental shift in how we interact with the internet. It is not just an upgrade of Web2 but an entirely new way of envisioning the online world. To understand Web3 better, let’s first take a look at Web2.

Web2: The Age of Centralization

Web2, often called the “Social Web” or the “Web of Data,” is the internet as most of us know it today. The dominance of centralized platforms like Facebook, Google, Amazon, and Twitter characterizes this era. In Web2, the primary focus is on user-generated content, social interactions, and centralized data control. Users contribute their data, often unwittingly, to these platforms in exchange for services, which are then monetized through advertising, data mining, and various other means.

However, the centralization of power and data in Web2 has led to numerous issues, such as privacy concerns, censorship, data breaches, and the unequal distribution of economic benefits. This prompted the need for a new approach, leading to the birth of Web3.

Web3: The Decentralized Web

Web3 represents a move towards a decentralized, open, and user-centric internet. At its core, Web3 aims to address the shortcomings of Web2 by reimagining how data and value are created, shared, and controlled online. Several key features that set Web3 from Web2 are:

1. Decentralization
Web3 is built on blockchain and other distributed ledger technologies, which promote decentralization. In Web2, many services and platforms are controlled by a few tech giants. In contrast, Web3 seeks to reduce this centralization by allowing users to interact directly with each other, without intermediaries. This means that users have more control over their data and digital interactions.

2. User Ownership of Data
One of the fundamental principles of Web3 is the concept of user-owned data. In the Web2 era, tech companies often collect and monetize user data without giving users much say in the matter. Web3 seeks to empower users by giving them control over their data and allowing them to decide who can access it.

3. Smart Contracts
Web3 introduces the concept of smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. These contracts run on blockchain networks and automate processes without the need for intermediaries. This can have a profound impact on various industries, including finance, supply chain management, and legal services.

4. Cryptocurrencies
Cryptocurrencies play a significant role in Web3. They enable new economic models, such as decentralized finance (DeFi) and non-fungible tokens (NFTs), which can revolutionize how we transact and exchange value online.

5. Trustless Systems
In Web2, we rely on centralized platforms to facilitate trust and transactions. Web3, on the other hand, aims to create trustless systems where trust is established through cryptographic verification and consensus algorithms, reducing the need for intermediaries.

6. Privacy and Security
Web2 has seen numerous data breaches and privacy scandals. Web3 puts a strong emphasis on privacy and security, using encryption and decentralized storage to protect user data.

7. Interoperability
Web3 aims to promote interoperability between different applications and platforms, making it easier for users to move data and assets across various services.

8. Open Source
Open-source software is a fundamental building block of Web3, enabling transparency, collaboration, and innovation.

9. Identity and Reputation
Web3 is exploring new ways to establish online identities and reputations that are portable and under the control of individuals, rather than centralized platforms.

10. Community Governance
Web3 projects often incorporate community-driven governance, where decisions about the platform’s rules and features are made collectively by users.

Web3 in Action

To better understand the potential of Web3, let’s look at some real-world examples:

1. Decentralized Finance (DeFi)
DeFi is one of the most visible Web3 applications. It uses blockchain technology to create an open, transparent, and accessible financial system for anyone with an internet connection. Users can use cryptocurrencies to borrow, lend, trade, and earn interest without relying on traditional banks or financial institutions.

2. Non-Fungible Tokens (NFTs)
NFTs are one-of-a-kind digital assets that represent ownership of digital art, collectibles, and virtual real estate. Web3 allows for the creation, ownership, and trade of NFTs, allowing artists and creators to directly monetize their digital works.

3. Web3 Browsers
Web3 browsers, like Brave and Opera, prioritize user privacy and block intrusive ads and trackers. They also provide built-in cryptocurrency wallets, making it easier for users to interact with blockchain-based applications.

4. Decentralized Social Media
Web3 has given rise to decentralized social media platforms that aim to return control to users. Projects like Mastodon, Peepeth, and Akasha are examples of this trend.

5. Decentralized File Storage
Web3 offers decentralized file storage solutions like IPFS (InterPlanetary File System) and Filecoin, which distribute data across a network of nodes, making it resistant to censorship and data loss.

Challenges and Considerations

While Web3 holds tremendous promise, it’s not without its challenges and considerations:

1. Scalability
Scalability remains a significant hurdle for Web3 technologies, as they must handle a growing user base and increased demand for services.

2. Regulatory Uncertainty
The regulatory landscape for cryptocurrencies and decentralized technologies is still evolving, and Web3 projects must navigate this uncertainty.

3. Usability
Web3 applications need to become more user-friendly to gain mass adoption. Many users find blockchain technology and cryptocurrency management complex.

4. Security
Although Web3 emphasizes security, it’s not immune to vulnerabilities and attacks. Smart contracts can have bugs, and users may still fall victim to phishing and scams.

5. Energy Consumption
Some Web3 blockchains, like Bitcoin and Ethereum, consume significant amounts of energy, leading to concerns about environmental sustainability.

Web3 is poised to be a significant leap forward in the evolution of the internet. By moving towards decentralization, user control, and transparency, Web3 aims to address many of the issues and concerns associated with Web2. While Web2 focuses on centralization and data exploitation, Web3 puts the power back into the hands of the users, fostering a more open, equitable, and user-centric internet. As Web3 continues to develop, we can expect to see even more innovations and opportunities in various sectors, ultimately reshaping the way we interact with the digital world.
