The internet as we know it today is dominated by centralized platforms like Google, Facebook, and Amazon. But there is growing excitement about how the internet’s next evolution, commonly known as Web3, aims to disrupt this status quo.
Web3 represents a conceptual shift towards decentralization, with blockchain technology allowing internet users to take back control of their data and online identities. The core premise of Web3 is to remove power from large tech monopolies and restore it to individuals.
In this beginner’s guide, we will demystify what is Web3 by exploring its origins, contrasting it with previous internet eras like Web2, highlighting the key benefits decentralization offers, and examining the role blockchain is playing in driving this online revolution. Let’s dive in to better understand the past, present and future of the internet.
The Evolution of the Web
To appreciate why Web3 matters, it helps to understand the history of the internet’s development.
Web1, lasting from 1991-2004, was the early internet of static websites and limited interactivity. Content was consumed more than created, and it required a developer’s skills to publish online.
The interactive, social internet we experience today is Web2, enabled by advances in software and faster connectivity. Web2 made it easy for anyone to create, share and engage with content across platforms like YouTube, Twitter, Instagram and TikTok.
But Web2 also came with downsides like centralized control over user data, privacy risks from tracking, censorship from platform gatekeepers, and pressure to monetize through ads.
Web3 has been proposed since the early 2000s as the solution – a decentralized internet where users control their own data and platforms have no central authority. The rollout of Web3 is still in progress, but its principles offer an inspiring vision for the internet’s next chapter.
What is Web3? Concise Definition
Web3 is the concept of a new decentralized iteration of the internet built on blockchain technology that aims to return power and control of online data and platforms to users. It relies on principles of decentralization, peer-to-peer networks, cryptography, and token-based economics to create a user-owned and governed internet rather than one dominated by large tech companies and platforms. The goal of Web3 is to build a fairer, more open and collaborative internet for the future based on open source, transparency, privacy, security and decentralized community ownership enabled by innovations in blockchain and distributed ledger technologies. While still early stage, Web3 promises to revolutionize how information, digital assets, identities and networks are managed online.

What Was Web1?
The original internet of the 1990s can be characterized as Web1. Key traits included:
- Websites were mostly static pages with text and images, lacking dynamic content.
- Creators had to know how to code and develop sites from scratch.
- Users consumed content more than creating it. Participation was limited.
- No centralized platforms existed. The web was fragmented and decentralized.
While limited, Web1 planted the seeds for an open and permissionless internet for everyone.
The Web2 World We Know Today
When we open apps and sites like YouTube, Facebook and Amazon today, we are interacting in the Web2 version of the internet. Here are some core attributes of Web2:
- Web technologies like JavaScript, HTML5 and CSS3 allowed dynamic, interactive online experiences.
- It became easy for anyone to create and share content, giving rise to user-generated sites.
- Platforms like social networks and search engines became central hubs of activity online.
- To fund growth, platforms turned to data exploitation and targeted ads.
- With scale came problems like centralized control, data privacy risks, and censorship.
Web2 made the internet accessible and engaging for millions globally. But the emergence of powerful intermediaries controlling so much of the online ecosystem led to new issues.

The Promising Potential of Web3
This sets the stage for understanding why Web3 aims to re-decentralize the internet and restore power to users. Benefits include:
- No centralized authority controls platforms or censors content.
- User data privacy and security is enhanced through blockchain encryption.
- New opportunities emerge to monetize apps and content directly.
- There is increased transparency, speed and efficiency in processes.
- Fault tolerance improves with no single point of failure.
Web3 promises an internet experience that answers many of the concerns that arose during the Web2 era.
Blockchain’s Role in Enabling Web3
A key innovation making the decentralized vision of Web3 possible is blockchain technology. Here are some ways blockchain is intertwined with Web3:
- Web3 platforms are built on decentralized peer-to-peer networks rather than centralized servers. Data is distributed across network nodes rather than controlled by a single entity.
- Blockchain allows the creation of decentralized apps (dApps) through trustless smart contract code rather than corporate-controlled software.
- Unique digital assets and currencies powered by blockchain expand online ownership rights.
- Transactions occurring on tamper-proof public ledgers enhance security and privacy.
- Blockchain enables new governance and incentive models aligning platform and user interests.
The technical attributes of blockchain architectures lend themselves naturally to powering decentralized and user-controlled internet applications.

The Internet’s Next Phase
Web3 represents the inspiring possibility of an internet that lives up to its original promise of openness and user empowerment. While still in its infancy, rapid advances in blockchain, crypto, VR, AI and 5G connectivity are converging to make Web3 a reality.
Mainstream adoption will take time as users get comfortable with new paradigms of internet interaction and governance. But the momentum towards decentralization is accelerating, pointing to Web3 principles transforming our online lives sooner rather than later.
Conclusion
By peeling back the layers of the internet’s evolution from Web1 to Web2 and now Web3, we can better understand the past and future of online technology. Web3’s vision of users controlling their data and destiny aims to solve many of the centralization issues inherent in today’s Web2 environment. With blockchain serving as a major engine, the next phase of the internet promises to be decentralized, secure and user-driven. While adoption is still nascent, Web3 represents an inspiring north star for the internet’s continued development.

FAQs about What is Web3
1. What is Web3?
Web3 refers to the vision of an internet that is decentralized, user-controlled, powered by blockchain/DLT, and moves away from the model of Web2 that consolidated power in the hands of a few dominant platforms and corporations like Google, Facebook, and Amazon
2. What is the Goal of Web3?
The core goal of Web3 is to decentralize power and control away from centralized entities and give it back to users through principles of decentralization, blockchain-based services, decentralized apps (dApps), and token-based economics.
3. What are some key examples of Web3 platforms and apps?
Some leading Web3 projects include cryptocurrency networks like Bitcoin and Ethereum, blockchain-based social platforms like Decentraland, peer-to-peer networks like Filecoin for data storage, privacy-focused browsers like Brave, and crypto gaming worlds like Axie Infinity.
4. What are the benefits of Web3?
Potential benefits of Web3 include user privacy, data security, censorship resistance, open and transparent processes, interoperability between applications, community ownership, and new models of economic cooperation and incentives.
5. How soon can we expect mainstream adoption of Web3?
Many technologists predict key components of Web3 like decentralized identity management and blockchain integration could go mainstream in 3-5 years. But full mainstream adoption likely remains 10-15 years away as underlying infrastructure improves and users become more comfortable with a decentralized internet paradigm.
