Software applications that operate on a blockchain network are known as decentralised applications, or DApps. They are intFweended to be decentralised, which means that no singular entity owns or controls them. Instead, they are peer-to-peer networks that are open-source and community-driven. DApps can be created on a number of different blockchain platforms, such as TRON, EOS, and Ethereum, to mention a few.

Decentralised web apps, also referred to as web 3 dapps, expand on the idea of DApps. They are web-based programs that run on decentralised systems like bitcoin and peer-to-peer networking. Web 3 DApps don't require a central server to store data or run computations, in contrast to conventional web apps.

We will delve deeper into Web 3 DApps in this piece, covering their advantages, benefits, and some well-known Web 3 DApp examples.

How do Web 3.0 DApps function?

Web 3 DApps run on a decentralised network, so their functionality is not reliant on a single central computer. Instead, they keep and process data using a peer-to-peer computer network. As there is no singular vulnerable point, they are therefore more resistant to censorship.

Blockchain technology is used by Web 3 DApps to manage and keep data. A Web 3 DApp's interactions with users are documented on the blockchain network. As a result, a permanent, impenetrable record of the exchange is produced, which anyone on the network can verify.

Smart contracts, which are self-executing contracts that autonomously enforce an agreement's terms, are also used by Web 3 DApps. On the blockchain, smart contracts are preprogrammed and are automatically carried out when specific requirements are fulfilled. A smart contract might be used, for instance, to automatically transfer money when a predetermined requirement is satisfied, like when a job is finished.

Gains from Web 3 DApps

The advantages of Web 3 DApps over conventional web apps are numerous. Among the main advantages are:

Web 3 DApps are decentralised in the sense that they are not owned or managed by a singular entity. They become more immune to censorship and singular points of failure as a result.

Since Web 3 DApps run on a blockchain network, every activity is tracked and visible to everyone using the network. High levels of accountability and openness are produced as a result.

Because Web 3 DApps use blockchain technology to keep and handle data, they are more secure than traditional web applications. They become less susceptible to hacking and data leaks as a result.


Because Web 3 DApps do not depend on centralised servers to store and manage data, they provide greater privacy. Data is instead kept on the blockchain network, which is harder to view without authorization.

Famous Web 3 DApps examples

Several well-known Web 3 DApps are presently in use. Some of the most well-known instances are as follows:

A decentralised exchange called Uniswap enables users to trade coins without the use of a centralised exchange. It employs an automated market maker system to provide liquidity and runs on the Ethereum blockchain.

Web browser Brave: Brave utilises blockchain technology to give users more privacy and security. Users can get paid to watch ads, and it blocks trackers and ads.

MakerDAO: MakerDAO is a decentralised lending platform that dispenses with the need for a central intermediary to facilitate cryptocurrency borrowing and lending. It utilises DAI, a stablecoin, as collateral and runs on the Ethereum blockchain.

With Augur, users can make predictions about the results of events and receive rewards for making correct predictions. Augur is a decentralized prediction market platform. It uses a decentralized oracle system to report on the result of events and runs on the Ethereum blockchain.

ChainlinkA decentralized oracle network known as Chainlink links blockchain-based smart contracts with actual facts and events. In addition to on-chain data, web APIs, and conventional payment systems, it enables smart contracts to obtain data from a wide range of sources.

The future of decentralised apps lies with Web 3 DApps. They provide greater protection, privacy, and transparency without being governed by a single entity. We can anticipate seeing more creative Web 3 DApps being created in a variety of sectors, including finance, gaming, and social media, as blockchain technology continues to advance.

Problems with web 3 DApps

Web 3 DApps have a lot to give, but there are also a lot of obstacles to overcome. Scalability is one of the greatest obstacles. Due to the limited number of transactions per second that blockchain networks can presently support, Web 3 DApps may find it challenging to handle high volumes of traffic. Additionally, it may be challenging for users to engage with Web 3 DApps due to the high gas fees needed to complete transactions on the blockchain.

User uptake is a problem for Web 3 DApps as well. Although the number of blockchain enthusiasts is growing, most people are still not conscious of the advantages of Web 3 DApps.

Because of this, it might be challenging for developers to draw users and create enduring communities around their apps.

Although web 3 dapps are still in their infancy, they have already demonstrated tremendous potential to upend established web apps and build a more democratic and decentralized online ecosystem. We can anticipate even more thrilling innovations in the years to come as more programmers and businesspeople investigate the potential of Web 3 DApps.
