What is Web3.0?
---------------

Web3.0, is the next evolution of the internet that aims to overcome the limitations and problems of the current centralized web. It is a new paradigm for how the internet works, based on the principles of decentralization, open-source, and user control.

*   Web1.0: Read Only
    
*   Web2.0: Read and Write
    
*   Web3.0: Read, Write and Own
    

In Web3.0, the internet is not controlled by a central authority or a small group of companies, but instead, it is built on decentralized technologies such as **blockchain**, **peer-to-peer networks**, and **distributed storage systems**. This enables users to own and control their data, interact with each other directly without intermediaries, and transact securely without the need for traditional financial institutions.

The decentralized web has many potential benefits, including

1.  increased privacy, security, and transparency
    
2.  increased more open and fair digital economy.
    

It is expected to enable new types of applications and services, such as decentralized finance (DeFi),and decentralized marketplaces(NFT).

Why Web3.0 is so popular?
-------------------------

Web3.0 is not simply about technological innovation, but rather about creating a new economic system within the network. Using blockchain as the underlying logic, a completely isolated economic system has been developed that does not require central managers. Instead, it is maintained and operated through its own incentive mechanisms, with its own currency, organizational structure(**DAO**).

This economic system requires a cryptocurrency to maintain the flow of value within the system, with each blockchain having its own native **token**, for example

*   Bitcoin
    
*   Ethereum
    
*   Tether
    

A **token** is needed to maintain the operation of the blockchain. Cryptocurrency is a token within the blockchain system.

There are several platforms built to trade crypotocurrency:

*   Binance

*   Coinbass

A new financial system has emerged to increase the liquidity of the cryptocurrency market, giving rise to a new direction in **DeFi** (Decentralized Finance): no need for banks, brokers, and other intermediary institutions.

Stablecoins are pegged to the US dollar at a 1:1 ratio:

*   Tether: algorithmically stable
    
*   Coinbase's USDC: 100% collateralized and pegged to the US dollar
    
*   Binance's BUSD: 100% collateralized and pegged to the US dollar
    

Different StableCoins may have different algorithms behind them.

The major public chains include:

*   Ethereum
    
*   BNB Chain
    
*   Polygon
    
*   Cardano
    
*   Polkadot
    

Other applications of blockchain technology include:

*   Using blockchain to enable the Internet of Things: [Helium](https://www.helium.com/)
    
*   Connecting blockchain with real-world data: [ChainLink](https://chain.link/)
    
*   Decentralized storage: [Filecoin](https://filecoin.io/)
