All you need to know about Web3 and its use cases

1. What is Web3 meaning?

Web3, also known as the decentralized web, is a term used to describe the next generation of the internet. It is based on blockchain technology and is designed to provide a decentralized infrastructure that is more secure and transparent than the current Web2. The primary goal of Web3 is to create an internet that is controlled by users, rather than large corporations.

Web3 is built on the blockchain, which is a distributed ledger technology that enables secure, transparent, and tamper-proof transactions. Blockchain technology allows for the creation of decentralized applications (DApps) that can run on a decentralized network without the need for a central authority to control them. DApps can be used to build decentralized marketplaces, social networks, voting systems, and more.

One of the key features of Web3 is its focus on user privacy. Web3 applications use encryption techniques to protect user data and transactions, making it difficult for third parties to intercept and misuse data.
 

2. What is Web3 used for?

Web3 has a wide range of potential use cases. Here are some of the most common applications:

A. Decentralized finance (DeFi)

DeFi is one of the most promising use cases for Web3 technology. DeFi applications are built on decentralized networks and allow users to access financial services without the need for intermediaries. DeFi platforms offer a wide range of financial services, including lending, borrowing, trading, and investing.

According to DeFi Pulse, the total value locked in DeFi protocols is over $89 billion as of February 2023. This figure was less than $1 billion at the start of 2020, indicating the explosive growth of the DeFi sector.
 

B. Decentralized marketplaces

Web3 technology can be used to build decentralized marketplaces that allow buyers and sellers to transact without the need for intermediaries. Decentralized marketplaces can help to reduce transaction costs, increase transparency, and reduce the risk of fraud.

One of the most well-known examples of a decentralized marketplace is OpenSea, a platform for buying and selling non-fungible tokens (NFTs). OpenSea has seen explosive growth in recent years, with over $16 billion in NFT sales in 2021 alone.
 

C. Digital identity

Web3 technology can be used to create digital identity systems that are more secure and user-centric than the current model. Digital identity systems built on blockchain technology can provide users with greater control over their personal data, reducing the risk of identity theft and other forms of fraud.

According to a report by MarketsandMarkets, the global digital identity market is expected to grow from $12.3 billion in 2021 to $30.5 billion by 2026, representing a compound annual growth rate (CAGR) of 19.8%.

D. Social networks

Web3 technology can be used to build decentralized social networks that are more user-centric and transparent than the current model. Decentralized social networks can help to reduce the power of large corporations and give users greater control over their data.

One example of a decentralized social network is Mastodon, a federated social network that has seen significant growth in recent years. According to Mastodon's website, the platform has over 4 million registered users.

E. Supply chain management

Web3 technology can also be used to improve supply chain management. By using blockchain technology, supply chain management systems can be made more transparent and efficient, reducing the risk of fraud and increasing trust between parties. This can help to reduce costs and increase supply chain resilience.

One example of a company using Web3 technology for supply chain management is IBM. IBM has developed a blockchain-based supply chain management system called Trust Your Supplier, which is designed to improve supplier onboarding, reduce administrative tasks, and increase supplier trust.

3.  What are real-world use cases of Web3?

Web3 technology is already being used in a wide range of real-world applications. Here are some of the most notable use cases:
 

A. Crypto Kitties

CryptoKitties is a popular DApp built on the Ethereum blockchain. The game allows users to collect and breed digital cats, which are represented as unique tokens on the blockchain. CryptoKitties was one of the first DApps to gain widespread attention and helped to demonstrate the potential of blockchain-based applications.
 

B. Uniswap

Uniswap is a decentralized exchange (DEX) built on the Ethereum blockchain. The platform allows users to trade cryptocurrencies without the need for intermediaries. Uniswap has become one of the most popular DEXs, with over $100 billion in trading volume as of February 2023.

C. Brave browser

The Brave browser is a privacy-focused web browser that is built on the Ethereum blockchain. The browser blocks ads and trackers by default and allows users to earn cryptocurrency for viewing ads. Brave has over 40 million active users as of February 2023.

D. NFT marketplaces

NFT marketplaces like OpenSea, Rarible, and SuperRare have become increasingly popular in recent years. These platforms allow users to buy and sell unique digital assets like art, music, and video game items. NFT sales have skyrocketed in recent years, with over $15 billion in sales in 2021 alone.

E. Crypto lending platforms

Crypto lending platforms like Aave and Compound allow users to earn interest on their cryptocurrency holdings by lending them out to other users. These platforms use smart contracts to automate the lending process and reduce the risk of default. According to DeFi Pulse, the total value locked in Aave and Compound is over $20 billion as of February 2023.

4.  Why Web3 is the future?

Web3 is the future because it represents a shift away from the centralized model of the current web to a more decentralized, user-centric model. Web3 technology has the potential to democratize the internet, reducing the power of large corporations and giving users greater control over their data.
