Imagine the internet you use every day: Instagram, YouTube, Google, WhatsApp.
You post photos, chat, shop, watch videos... but almost everything you do is controlled by a few big companies. They own your data, show you ads based on it, and can change rules or ban accounts anytime.
Web3 is the next version of the internet that fixes this.
It's built on blockchain technology — think of it as a super-secure, shared digital notebook that no single person or company fully controls.
Web1 (1990s–2000s): Read-only. Static websites, like online newspapers.
Web2 (2000s–now): Read + Write. Social media, apps — but big tech owns your data and profits from it.
Web3 (now growing fast in 2026): Read + Write + Own. You control your data, digital stuff, and even earn from your online activity.
Ethereum (ETH) — The backbone of Web3
Chainlink (LINK) — The oracle king Connects blockchains to real-world data
Polkadot (DOT) — Interoperability leader Enables different blockchains to connect and share data securely. Great for cross-chain Web3 ecosystems.
