The term Web3 has surged in popularity across tech circles, social media, and investment forums. But few know it was coined back in 2014 by computer scientist Gavin Wood—co-founder of Ethereum and founder of Parity Technologies. In a recent conversation on CNBC’s Beyond the Valley podcast, Wood unpacked his original vision: a decentralized, user-empowered internet that challenges the dominance of today’s tech giants.
This article explores what Web3 truly means, how it differs from today’s web, the core technologies behind it, and whether it can realistically reshape the digital world.
The Problem with Today’s Internet
The modern internet—often referred to as Web2—is dominated by a handful of powerful corporations like Amazon, Microsoft, and Google. These companies control vast swaths of digital infrastructure, from cloud hosting to social media platforms, and wield immense influence over how users interact online.
Gavin Wood describes this concentration of power as inherently risky.

“The big problem with this is… placing all your eggs in one basket. If something goes wrong with one of these services, it becomes suddenly unavailable for an awful lot of people,” Wood explained.
Beyond reliability, the issue comes down to trust. Users must trust these centralized entities to protect their data, enforce fair policies, and operate transparently. But history has shown that trust can be broken—through data breaches, censorship, algorithmic manipulation, or sudden policy changes.
Wood sees Web2 as a drift from the original promise of the internet—a decentralized, open space where no single entity holds control. Web3, he argues, is a return to that ideal.
What Is Web3? A Decentralized Alternative
At its core, Web3 is a vision for a peer-to-peer internet, where services aren’t hosted by single corporations but run algorithmically across distributed networks. Instead of relying on Amazon Web Services or Google Cloud, applications live on decentralized blockchains maintained by global participants.
“Web3 is really an alternative vision of the web… services are not hosted by a single provider but are purely algorithmic things hosted by everybody,” Wood said.
In this model:
- No single company owns the platform.
- Users retain ownership of their data and digital assets.
- Control is distributed across a network of nodes (computers) rather than centralized servers.
- Participation is permissionless—anyone can join or contribute.
This creates a more democratic and resilient internet. If one node fails, others keep the system running. There’s no central point of failure—and no single gatekeeper deciding who gets access or what content stays online.
Core Technologies Powering Web3
Two foundational concepts underpin Web3: blockchain technology and decentralization.
Blockchain: The Backbone of Trustlessness
Blockchain is most famously associated with Bitcoin, but its application extends far beyond cryptocurrency. It’s a distributed ledger that records transactions across many computers in a way that makes them tamper-resistant and transparent.
In Web3, blockchain enables trustless interactions—meaning users don’t need to trust a company or intermediary. Instead, they trust code. Smart contracts (self-executing agreements written in code) automate processes like payments, content moderation, or identity verification without human intervention.
For example:
- A decentralized social media app could use blockchain to verify user identities cryptographically.
- Content moderation could be governed by community voting via smart contracts.
- Revenue from ads or subscriptions could be distributed directly to creators via tokens.
Decentralization: Shifting Power to Users
Decentralization isn’t just technical—it’s philosophical. It aims to redistribute power from corporations back to individuals. In a Web3 world:
- Users own their digital identities.
- Data isn’t harvested for profit without consent.
- Platforms can’t unilaterally ban users or alter rules overnight.
This shift supports greater freedom of expression, data sovereignty, and financial inclusion, especially in regions with unstable banking systems or restrictive governments.
A Web3 Version of Twitter: What Would It Look Like?
Imagine a version of Twitter where:
- No central company controls the platform.
- Your tweets are stored on a blockchain, making them immutable.
- Your identity is verified through cryptographic keys—making impersonation nearly impossible.
- Content moderation is handled by decentralized governance models (e.g., token-based voting).
Wood believes such a system would offer stronger protections against fraud and censorship.
“It’s much harder for someone to fake my identity because we have cryptographic proofs that I did this—and only I could have done this.”
Additionally, users could earn tokens for creating valuable content or moderating discussions, creating new economic models beyond ad revenue.

The Role of Cryptocurrency in Web3
While many equate Web3 with crypto, Wood clarifies that digital currencies aren’t always necessary.
Yes, many current Web3 apps rely on tokens—like Ether (ETH) on Ethereum—to pay for transactions or incentivize network participation. But Wood envisions a future where services function seamlessly without requiring users to hold or trade tokens.
“I suspect currency will continue to play a role… but I think overall, we’re going to see services delivered without the need to use tokens.”
This evolution is critical for mainstream adoption. Most people don’t want to juggle multiple cryptocurrencies just to post online or stream music. The goal is to hide complexity behind intuitive interfaces—similar to how most internet users don’t understand TCP/IP but still browse effortlessly.
How Will Regulation Work in a Decentralized World?
Regulating decentralized systems presents unique challenges. Bitcoin, for instance, has never been directly regulated because no single entity owns it. Yet exchanges and wallet providers face increasing oversight.
Wood suggests regulators may shift focus:
- From regulating services to regulating users.
- From targeting protocols to targeting front-end applications built on them.
He also believes some Web3 apps may voluntarily adopt compliance measures—not because they’re forced to, but because it benefits their users and long-term sustainability.
“It could be in an app’s own self-interest… to bring in rules that align with regulators.”
This hybrid approach might allow innovation to flourish while addressing concerns around fraud, money laundering, and consumer protection.
Will Web3 End the Reign of Tech Giants?
While Web3 promises to challenge Big Tech’s dominance, the reality is more nuanced.
Companies like Microsoft and Twitter are already investing in blockchain and decentralized projects. Rather than being replaced, they may absorb or co-opt aspects of Web3—launching their own tokenized platforms or NFT marketplaces.
But Wood remains optimistic. He compares today’s tech giants to Microsoft in the 2000s:
“It didn’t matter that you were running Windows… we use the web as a platform now.”
Just as the web broke desktop monopolies, Web3 could render centralized platforms obsolete—not by defeating them head-on, but by offering a superior, open alternative.

A: No. The metaverse refers to immersive virtual worlds; Web3 refers to the underlying decentralized infrastructure that could power them.
Q: Do I need cryptocurrency to use Web3?
A: Some apps require tokens for access or transactions, but future iterations aim to work without user-facing crypto.
Q: Can Web3 stop censorship?
A: It reduces reliance on centralized gatekeepers, making large-scale censorship harder—but not impossible—at the protocol level.
Q: Is Web3 secure?
A: Blockchain-based systems are highly secure against tampering, but smart contract bugs and phishing attacks remain risks.

Final Thoughts
Web3 isn’t just about technology—it’s about reshaping power dynamics online. By returning control to users through decentralization, blockchain, and cryptographic verification, it offers a bold alternative to today’s surveillance-driven web.
While challenges remain—from scalability to regulation—the movement represents a growing demand for transparency, ownership, and digital freedom. Whether it fully displaces Big Tech or evolves alongside it, one thing is clear: the conversation about the future of the internet has fundamentally changed.
And it all started with a simple idea: an internet owned by everyone—and no one.
