Decentralized applications – dApps are digital applications or programs that exist and run on a blockchain or peer to peer (P2P) computer network rather than on a single computer. DApps (also called “dapps”) are therefore outside the scope and control of a single authority.
DApps, which are often created on the Ethereum platform, can be developed for a wide variety of purposes, such as gaming, finance and social networking.
In a Nutshell
- A decentralized network, as opposed to a single computer or server, is where DApps run.
- They are transparent, censorship resistant, and open source.
- A wide range of uses, including gaming, finance, and social networking, are possible for DApps.
- DApps have been created to decentralize and remove the middleman from a variety of processes and applications, including finance, supply chain management, identity verification, real estate, healthcare, education, social networking, and predictive markets.
- DApps are in their early stages and subject to a variety of problems and unknowns, including scalability, user interface changes, and code alterations.
- Ethereum dApps are implemented on the Ethereum network and use smart contracts for their logic.
- While decentralized applications: dApps enable users to do direct business with one another, centralized applications are owned by a single corporation and rely on a central authority.
Decentralized Applications – dApps
A standard web application, such as Uber or Twitter, runs on a computer system that is owned and managed by an organization, giving it full authority over the application and its operation. There may be multiple users on one side, but the backend is controlled by a single organization.
Decentralized applications – dApps are the future of the internet.

DApps can run on a P2P network or on a blockchain network. For example, BitTorrent, Tor and Popcorn Time are applications that run on computers that are part of a P2P network, where multiple participants consume content, feed or seed content, or simultaneously perform both functions.
In the context of cryptocurrencies, dApps run on a blockchain network in a public, open source and decentralized environment, and are free from the control and interference of any authority. For example, a developer can create a dApp similar to Twitter and place it on a blockchain where any user can publish messages. Once published, no one including the app’s creators can delete them.
Uses of the Decentralized Applications – dApps
dApps have been developed to decentralize and disintermediate a range of functions and applications. These include everything from self executing financial contracts to multi user games and social networking platforms. DApps can also be integrated into web browsers to function as plugins that can help serve ads, track user behavior and solicit cryptocurrencies.
Some examples of practical uses of dApps are:
- Financial services: dApps can be used to facilitate peer to peer financial transactions, such as currency exchange or asset transfers.
- Supply chain management: dApps can be used to track the movement of goods through a supply chain, ensuring transparency and accountability.
- Identity verification: dApps can be used to securely store and verify identity information, such as for voting systems or passport applications.
- Real estate companies: dApps can be used to facilitate the purchase and sale of real estate directly between buyer and seller, as well as tracking property ownership and related documentation, such as deeds.
- Healthcare: dApps can be used to store and track medical records, as well as facilitate communication and collaboration for healthcare professionals.
- Education: dApps can be used to create decentralized learning platforms, allowing students and teachers to interact and collaborate directly without the need for intermediaries.
- Social media: dApps can be used to create decentralized social media platforms, allowing users to interact and share content without the need for a central authority.
- Predictive markets: dApps can be used to create decentralized predictive market platforms, allowing users to make predictions on a variety of topics and potentially earn rewards for accurate predictions.
dApp scams
There are several types of scams that have been perpetrated through decentralized applications – dApps. Ponzi schemes, in which early investors are paid from the investments of later investors, have occurred in decentralized apps.
Fake initial coin offerings (ICOs) have also been used to raise funds for the development of a new cryptocurrency or dApp, but are actually designed to steal investors’ money without actually developing a viable product.
Phishing attacks, which use fake websites or emails to trick users into revealing sensitive information, have also been seen on dApps. In addition, some dApps have been used to distribute malware or viruses, which can compromise users’ devices and steal sensitive information. It is important for users to exercise caution and due diligence when interacting with dApps, as the decentralized nature of these applications can make it difficult to track or hold perpetrators accountable.

Industry analysis group DappRadar found that there were a record 312 hacks and vulnerabilities affecting dApps in 2022, resulting in losses of around $48 billion.
Advantages and disadvantages of Decentralized Applications – dApps
Advantages
Many of the advantages of dApps center on the program’s ability to safeguard user privacy. With decentralized apps, users do not need to submit their personal information to use the function offered by the app. DApps use smart contracts to complete the transaction between two anonymous parties without relying on a central authority.
Free speech advocates point out that dApps can be developed as alternative social media platforms. A decentralized social media platform would be resistant to censorship because no blockchain participant can remove messages or prevent them from being published.
Ethereum is a flexible platform for creating new dApps, providing the necessary infrastructure for developers to focus their efforts on finding innovative uses for digital applications. This could enable the rapid deployment of dApps in a wide variety of sectors, such as banking and finance, gaming, social networking and online shopping.
American cryptographer and computer scientist Nick Szabo introduced the term “smart contract” in 1996 as a graduate student at the University of Washington.
Disadvantages of Decentralized Applications – dApps
The use of dApps is still in its early stages, so it is experimental and prone to certain problems and unknowns. There are doubts as to whether applications will be able to scale efficiently, especially in the event that an app requires significant computation and overloads a network, causing it to become congested.
The ability to develop a user friendly interface is another concern. Most users of applications developed by traditional centralized institutions have expectations of ease of use that encourage them to use and interact with the application. Getting people to switch to dApps will require developers to create an end user experience and level of performance that rivals already popular and established programs.
The challenge of making code modifications is another limitation of dApps. Once deployed, a dApp is likely to require ongoing changes to introduce enhancements or fix bugs or security risks. According to Ethereum, it can be difficult for developers to make necessary updates to dApps because the data and code published on the blockchain are difficult to modify.

What are Ethereum dApps?
These are decentralized applications – dApps that operate and are developed using the Ethereum platform. Ethereum dApps use smart contracts for their logic. They are deployed on the Ethereum network and use the platform’s blockchain to store data.
What is the difference between a centralized and a decentralized application?
A centralized application is owned by a single company. The application software for a centralized application resides on one or more servers controlled by the company. As a user, you interact with the application by downloading a copy of the application and sending and receiving data from the company’s server.
The decentralized applications – dApps run on a blockchain or peer to peer computer network. It allows users to transact directly with each other, rather than relying on a central authority. The user of a dApp will pay the developer a cryptocurrency amount to download and use the source code of the program. The source code is known as a smart contract, which allows users to transact without revealing personal information.
What are examples of centralized and decentralized applications – dApps?
Well known examples of centralized applications are Twitter, Facebook, Instagram and Netflix. Banks and other financial institutions use centralized applications to enable their customers to access their accounts online.Peepeth, a social network alternative to Twitter, is an example of a decentralized app. Cryptokitties is a dApp game that allows users to buy and sell virtual cats. MakerDAO is a decentralized credit service that backs the Dai stablecoin and allows users to open a collateralized debt position (CDP).
Wrap Up
By enabling peer to peer interactions and transactions without the need for a central authority, decentralized apps have the potential to disrupt established sectors. They have advantages like user privacy and resistance to censorship, despite being in their early stages and facing difficulties with scale and user interface. The adoption and integration of dApps into numerous economic areas may increase as they continue to develop.
