Introduction to Web3: Taking Back the Internet



The internet as we know it is changing — again. We’ve seen the rise of static web pages in the early 90s (Web1), followed by the age of social media and user-generated content (Web2). Now, the next evolution is unfolding: Web3.

But what is Web3, and why is it being hailed as the next frontier of the digital world?

What is Web3?

At its core, Web3 is a vision for a decentralized internet — one where users have ownership of their data, digital assets, and online identities. Built using blockchain and decentralized protocols, Web3 aims to eliminate the control of centralized platforms and empower individuals instead.

In Web2, tech giants like Facebook and Google control your personal data, content, and monetization opportunities. In Web3, the control shifts back to you.

Key Characteristics of Web3

Decentralization
Data and services are hosted on peer-to-peer networks instead of centralized servers.

Ownership
Users can own digital assets like tokens, NFTs, or domain names tied to their wallets.

Token Economies
Community tokens or cryptocurrencies fuel activity, reward participation, and power governance.

Open Access
Anyone with an internet connection can participate — no permissions, no gatekeepers.

Interoperability
dApps (decentralized apps) can connect and share information seamlessly across platforms.

Web3 in Practice

Web3 isn’t just a concept — it’s already here in early form. Some real-world examples include:

OpenSea — a marketplace for NFTs that runs on Ethereum

Brave Browser — a privacy-first browser that rewards users with BAT tokens

ENS (Ethereum Name Service) — a decentralized version of DNS (like .eth domains)

These tools allow users to engage, earn, and build — all without relying on centralized companies.

Why Does Web3 Matter?

In a time where personal data is sold, content creators are underpaid, and platform bans can wipe out livelihoods, Web3 offers an alternative. It shifts power away from centralized tech companies and gives it back to communities and creators.

With Web3:

Artists can mint and sell their own work without giving up 50% to middlemen

Users can earn tokens for contributions to platforms they actually help build

Communities can vote on decisions that affect the software they use

Reflective Question

How could Web3 reshape the way we use social media, shop online, or build communities?

Web3 is about user empowerment, ownership, and control. It’s still early, and the ecosystem is growing — but the future of a more open, fair internet is already unfolding.

By Thabiso Njoko  Mbabane, Eswatini — April 8, 2025 It’s not every day that a room full of economists, statisticians, tourism operators, government officials, and academics come together with a shared purpose: building a smarter, data-driven future for Eswatini. That’s exactly what happened on Day 1 of the African Trade Observatory (ATO) Trade in Services Workshop, hosted in Mbabane and facilitated by two powerhouse experts from the International Trade Centre (ITC) — Katerina Blanchard and Christophe Durand. With the African Continental Free Trade Area (AfCFTA) gaining momentum, countries like Eswatini are looking to strengthen their trade systems, not just in goods, but also in services . And it all begins with data—clean, clear, internationally aligned data. From Concepts to Conversations: Setting the Tone for Trade Intelligence The day began with a warm welcome and a walkthrough of the ATO project , where Blanchard and Durand laid out the bigger picture: why travel services da...

Strengthening Travel Data Collection in Eswatini: Global Lessons, Local Action: Day 2

Image
Date:  14 April 2025 By:   Thabiso Njoko Introduction On April 9, 2025, the International Trade Centre (ITC) conducted the second day of its specialized training workshop in Eswatini, aimed at enhancing the collection and integration of travel service data. This initiative, part of a broader African trade development effort, spotlighted the importance of accurate travel statistics for compiling the Balance of Payments (BoP) and guiding effective policymaking. Understanding the Complexity of Travel Data Travel services are distinct within international trade due to their direct, on-the-ground interaction between travelers and service providers. However, capturing this data poses challenges for many developing countries, owing to its fragmented nature, high collection costs, and technical intricacies. The ITC outlined a variety of data sources used globally, including: Personal and Household Surveys Enterprise and Establishment Surveys International Transactions Rep...
