The internet has become an integral part of our lives, allowing us to connect, share information and conduct transactions globally. However, as technology advances, concerns arise regarding privacy, security and control over personal data. This is why Web 3 is emerging as a promising concept, offering an evolution of the internet that is more decentralized, secure and prioritizes user privacy.

### What is Web 3?

Web 3 is a vision for the internet of the future that fixes some of the weaknesses that exist in the currently dominant Web 2.0 model. In Web 3, the principles of decentralization, security, and privacy are the main focus. Blockchain technology, smart contracts, and other decentralized protocols are the foundation for building Web 3 infrastructure.

### Web Key Principles 3:

1. Decentralization: In contrast to Web 2.0 which often relies on large companies as intermediaries, Web 3 seeks to build a more decentralized platform. This means no single entity controls all data and online activity.

2. Security: Blockchain technology is the backbone of security in the Web 3. By storing data encrypted and distributed across various network nodes, the risk of data manipulation and cyber attacks can be significantly reduced.

3. User Privacy: Web 3 gives users more control over their data and identity online. By using a decentralized identity system and a more secure authorization model, users can have more confidence in sharing information online without worrying about privacy violations.

### How is Web 3 Creating Change?

1. Financial Transactions: Using blockchain technology, Web 3 is changing the way we carry out financial transactions online. With smart contracts, transactions can be processed without the need for intermediaries, reducing costs and increasing transaction speed.

2. Decentralized Applications (DApps): Web 3 supports the development of decentralized applications (DApps) that do not depend on a central server. This means users have more control over their data and don't have to worry about services suddenly shutting down or data being stolen.

3. Openness and Innovation: By building a more decentralized platform, Web 3 encourages innovation and creativity. Anyone can build and develop applications without needing permission from a central authority, opening the door to more possibilities in the internet ecosystem.

### Conclusion:

Web 3 is a promising evolution of the internet, offering an online environment that is more decentralized, secure, and prioritizes user privacy. By leveraging blockchain technology and decentralization principles, Web 3 provides solutions to some of the weaknesses that exist in the current Web 2.0 model. While it may still be in its infancy, Web 3 promises a more open, secure, and powerful internet future for everyone.

There is no official coin called “Web3” in the crypto protocol. However, there are several blockchain projects that are often associated with the Web 3.0 vision, such as Polkadot, Livepeer, and Ocean Protocol. Polkadot is a decentralized blockchain platform that allows different blockchains to interact and communicate with each other. Livepeer is a protocol for decentralized video streaming, while Ocean Protocol is a decentralized infrastructure for sharing data and powering AI-based services. All these projects aim to realize the Web 3.0 vision in different ways.
