Web3, or Web3.0, refers to the third iteration of the World Wide Web. It represents advancements in computing technology over the years, transcending Web2.0.
Many advocates of this new internet vision argue that the current web is overly centralized in the hands of a few corporations known as "Big Tech." For them, the solution lies in decentralizing the web. Other Web3 concepts include the Internet of Things (IoT), the Metaverse, artificial intelligence (AI), and blockchain. This post explores how these elements interconnect.
The Evolution of the Web
The web comprises hardware and software working together to create the global network of computers we call the internet. Technology evolves rapidly—some advancements even exponentially.
When ARPANET began in 1969, the memory capacity of the Honeywell DDP-516 was a mere 24KB with a 2MHz CPU. Over the years, hardware improvements led to software enhancements. Today, we have multi-core GHz CPUs and near-unlimited system memory. This evolution didn’t happen overnight; it progressed gradually, and so did the web.
Web1.0: The Static Web
The first generation of the internet consisted of static pages delivered to clients requesting information.
Web2.0: The Interactive Web
The second generation introduced user input, creating dynamic data to serve others. This era birthed social media, programmable APIs, and complex services.
Web3.0: The Decentralized Web
The third generation is emerging, but its final form depends on developing technologies. Today’s smartphones outperform the Cray-1 supercomputer from 1975.
Web3 isn’t the Metaverse, but the Metaverse could be part of it. While the Metaverse focuses on user experience (e.g., virtual and augmented reality), Web3 revolves around how the future internet will function.
Web3 vs. IoT
The Internet of Things (IoT) isn’t Web3 but could be integral to it. IoT devices—like Amazon Echo or smart factories—operate independently but communicate via networks to enhance daily life or productivity.
Web3 vs. AI
Artificial intelligence is advancing rapidly. Modern smartphones can perform impressive AI tasks, while cloud-based AI systems leverage Tier-1 broadband speeds to create new internet infrastructure. Data science and AI remain core to Web3.
Web3 vs. Blockchain
Blockchain enables decentralized crypto networks like Bitcoin and Ethereum. However, current blockchains are resource-intensive—Bitcoin and Ethereum consume more energy than some countries. Despite this, blockchain remains a reliable transaction-recording tool, potentially vital for a Metaverse economy.
The Big Tech Problem
Centralization is a key issue with Web2.0. Giants like Google, Amazon, Meta, Apple, and Microsoft (GAMAM) wield excessive control, often at the expense of users and developers. Decentralization offers a solution, empowering creators to own their content and choose its use.
Tokenomics and Decentralization
Decentralization ensures contributors receive fair value via crypto tokens. Transitioning to this model faces hurdles, including resistance from incumbent tech giants and increasing global crypto regulations.
Tokenized Enterprises
Imagine Google open-sourcing its search algorithm and paying users in G-tokens for ad interactions. Similarly, Facebook could reward users with Face-tokens for browsing. While unlikely, tokenized cooperatives—supported by blockchain—are feasible.
Features of Web3
- Decentralization: No central control, fostering user freedom (e.g., DApps, DeFi).
- Permissionless Use: No gatekeepers.
- Open Source: Enhances security and innovation.
- Developer Incentives: Tokens attract more contributors.
- User Rewards: Quality content earns tokens.
- Censorship Resistance: Public protocols override dictatorial control.
- Community Governance: Token-based voting empowers visionaries.
- Augmented Reality: Metaverse blends virtual and physical worlds.
- Advanced AI: Smarter robots and systems.
Technical Challenges
- Scaling: Difficult for decentralized apps (dApps).
- Speed: Blockchains lag behind traditional tech.
- Centralization Reliance: Even decentralized networks depend on centralized exchanges.
- Privacy: Handling blockchain data.
- Theft: Rising crypto-asset theft.
- Energy: Crypto mining is inefficient.
Social Risks
- Cybercrime
- Child exploitation
- Hate speech
- Government overreach
