🧠 So, to put it simply, what is Web 3.0?

The next version of the internet, known as Web 3.0, gives individuals greater control over their digital assets, identities, and data.

With the help of blockchain technology, smart contracts, and decentralized apps (dApps), Web 3.0 seeks to return power to consumers rather than depending on centralized businesses like Meta, Google, or Amazon.

Important Web 3.0 Features

1. Dispersion

Data is not kept on a single company’s server, but rather on a network (blockchain). This implies that there isn’t a single point of failure or control.

2. Powered by Blockchain

Blockchain guarantees traceability, security, and transparency. Verification is possible for everything, including transactions and digital asset ownership.

3. Ownership by Users

Digital assets, such as tokens, NFTs, and even your data, can be owned by you without requiring intermediary consent.

4. Intelligent Contracts

These are coded agreements that carry out their actions. No firm or attorney was required to handle or approve.

5. Improved Privacy

You can decide when and how to provide personal information, and your identity can stay anonymous.

Examples of Web 3.0 in the Real World

• Cryptocurrencies such as Ethereum or Bitcoin
• Non-fungible tokens (NFTs) for collectibles, music, and art
• Platforms for decentralized finance (DeFi) that enable lending, borrowing, and interest earning without the use of banks
• Decentralized social media platforms such as Lens Protocol and Mastodon
• Brave Browser, which safeguards your privacy while rewarding you for watching advertisements
