7 Web3.0 Examples in Fast Evolving World

June 19, 2024

The launch of Web 3.0 heralds an exciting period of decentralized technology and creative applications as the digital world continues to change. This article explores seven noteworthy examples of Web3.0 that will shape digital interaction and cooperation in the future. The innovative potential of Web 3.0 applications in transforming numerous industries and redefining our interactions with the digital world is demonstrated by these examples, which range from decentralized finance (DeFi) platforms to non-fungible tokens (NFTs) and decentralized autonomous organizations (DAOs).

1. Smart contracts

Smart contracts

Smart contracts are self-executing contracts with the agreement's conditions directly encoded into the code. When certain circumstances are satisfied, these contracts automatically carry out and enforce agreements without the need for middlemen or human intervention.

Smart contracts are essential for trustless and decentralized transactions as a Web3 application, which includes decentralized technologies like blockchain and decentralized finance (DeFi). By offering a safe and transparent method for carrying out contracts and moving digital assets on blockchain networks, they facilitate many applications, including decentralized exchanges, lending platforms, and decentralized autonomous organizations (DAOs).

The homeowner in a smart home can establish a set of rules that control how these IoT devices interact with one another using smart contracts on a blockchain. As an illustration, the security camera is programmed to capture images each time the smart lock is opened. The video is recorded and safely kept on the blockchain with decentralized storage systems like IPFS. Thanks to the smart contract, the footage can only be accessed by those permitted.

2. Brave browser

The Brave browser is one of the most popular Web 3.0 applications available today. However, the security it offers against Web 2.0 aspects like cookies and trackers attracts many users, rather than its Web 3.0 features. Its emphasis on privacy is its main asset, as users can block online advertisements and website trackers without the need for other plugins. Additionally, it is mobile device compatible, which appeals especially to people who want to use their smartphones to view YouTube without advertisements.

Brave, which is based on Chromium, prioritizes privacy and the combination of decentralized financing (DeFi) and decentralized apps (DApps). It also allows users to earn cryptocurrency while using the network by offering prizes in its token.

For example, a person who is worried about their privacy and frequently browses the Internet. They may guarantee a more efficient surfing experience by blocking intrusive trackers and advertisements using the Brave browser. Furthermore, by participating in Brave's rewards program, users can earn cryptocurrency just by using the browser for regular tasks.

3. Decentraland

This project, which runs on the Ethereum (ETH) blockchain, seeks to create a large virtual environment where users can participate in activities that are similar to those that take place in the real world.

This project's standout feature is consistent with Web3 application principles. Firstly, it presents MANA, its currency that is the main means of commerce in the virtual world and is valued according to supply and demand dynamics. It also functions as a decentralized autonomous organization (DAO), meaning that there is no central regulating body. Rather, all token owners have the right to take part in organizational decision-making. Moreover, information created in the virtual world is disseminated and safely kept on the company's Ethereum blockchain.

Users can use MANA to buy real estate in a virtual world. The value of MANA may rise in tandem with an increase in the number of users and the demand for virtual properties. Furthermore, MANA token holders can participate in governance choices related to the creation and administration of the virtual environment, guaranteeing a cooperative and inclusive decision-making process.

4. Decentralized data marketplace

Decentralized data marketplaces on the blockchain can be made possible by Web3 technologies, offering a safe environment for the exchange of IoT data while upholding people's privacy and rights.

A situation where a healthcare consortium creates a platform for safely sharing patient data among hospitals, research facilities, and pharmaceutical businesses can be considered as an example of a decentralized data marketplace.

To support medical research and drug development, hospitals can safely exchange anonymized patient data with academic institutions without risking patient privacy. By guaranteeing the traceability and integrity of data transactions, the blockchain-based marketplace enables users to confirm the legitimacy and ancestry of shared data.

5. Decentralized autonomous IoT

Decentralized autonomous IoT

The Web3 application with IoT is the creation of Decentralized autonomous organizations (DAOs), which enable IoT devices to make choices on their own. This can improve the responsiveness and efficiency of interconnected systems.

Envision a smart city that comprises an interconnected network of IoT devices, including parking meters, air quality sensors, traffic signals, and street lighting. A DAO that uses smart contracts to automate decision-making and coordination is in charge of these gadgets. One key aspect of this network is the ability to IoT monitor traffic, allowing for real-time adjustments to traffic signals and improved traffic flow management.

To save energy, streetlights are programmed to turn on and off in response to scheduled changes in ambient light levels. Streetlights can automatically alert the DAO's maintenance system when they malfunction.

Vehicle occupancy sensors are connected to parking meters. Guaranteeing available parking spaces, the DAOs dynamically modify parking charges in response to demand. Also, DAO's cryptocurrency is used to handle payments automatically.

Decentralized control systems

By enabling decentralized control systems, Web3 alters Industrial IoT and brings about advantages like supply chain optimization, predictive maintenance, and safe data exchange. For instance, an intelligent manufacturing floor that has a variety of IoT-capable devices and robots. The factory uses a decentralized control architecture in place of a centralized control system to oversee every machine. A robotic arm that assembles products can modify its motions without waiting for orders from a central PLC by using input from its sensors.

With a decentralized control system, the machines in the smart factory can function with greater autonomy, coordinating with one another and using local knowledge to make decisions.

7. Storj

As was already said, one of the main concerns that Web 3.0 seeks to resolve is information and data ownership and security. One of the safest cloud storage options is Storj, which is especially appreciated by people who handle sensitive material, including politicians and journalists.

To accommodate varying user preferences, Storj has two unique upload interfaces: an easy-to-use web client for users looking for a quick and uncomplicated decentralized process, and a more complex command line interface for more experienced users. Storj's simple UI makes it easy to use and intuitive for users to navigate. Up to 150 gigabytes of storage are available for free, and like many Web 3.0 services, using the plan entitles users to earn STORJ, the native currency of the platform.

Take a journalist who has to securely communicate and preserve sensitive materials, for instance. They can upload files to the decentralized cloud storage platform through Storj, which offers more privacy and security than conventional centralized storage options. Furthermore, users can obtain STORJ tokens by using the platform, which adds even more motivation to use STORJ for their data storage requirements.


To sum up, the presentation highlights Web3.0 examples of technologies' quick development and revolutionary possibilities in our increasingly digital society. These examples, which range from secure cloud storage solutions and decentralized autonomous organizations (DAOs) to decentralized finance (DeFi) platforms and non-fungible tokens, show creative ways to tackle persistent problems and challenge established ideas.

Web3.0 has the potential to transform many industries, improve digital collaboration, and give people more control over their assets and data as it continues to gain popularity.
