Guide To Decentralized Applications (Dapps)

I believe we’re changing the world one blockchain at a time and if we use his technology properly we are bound to make the world a better place for everyone so to help make that happen in this article I will be talking to you about Dapps the app is short for a decentralized application and Dapps are a very important part in the world of blockchain so in this article, I will tell you exactly What are DApps?

definition of DApps

A Dapp stands for a Decentralized Application  In the context of blockchain, Dapps are interfaces that interact with the blockchain through the use of smart contracts. A smart contract code lives on the blockchain and runs exactly as programmed. Once smart contracts are deployed on the network you can not change them. Dapps are controlled by the logic written into the contract, not an individual or company.  Dapps look and behave like regular web and mobile apps, except that they interact with a blockchain in different ways. Some may require crypto tokens to use the Dapp, storing user data onto the blockchain, and so on. A decentralized App has its backend code running on a decentralized peer-to-peer network. Contrast this with a traditional application where the backend code is running on centralized servers. DApps may have frontend code and UI written in any language to make calls to their backend. 

Benefits of Dapps

Dapps are built on top of decentralized  blockchain networks such as Ethereum, Cardano,  or Solana and usually have the following benefits  that they inherit from the use  of blockchain technology: 

open source

by being open source what it means is that anybody can look at the source code this prevents anybody from hiding anything inside that source code this is very different from closed source software in which case somebody could simply make modifications and some people may not know what’s inside so by default, the apps need to be open source.

Run-on a public blockchain

DApp is stored through a blockchain, which is a decentralized and distributed database. Blockchains make certain that there is no central point of failure. If a hacker wants to access the data stored on a blockchain, they will have to go thru the whole network and breach each node. This makes hacking a blockchain virtually impossible.

No single entity

DApps are not owned by a single entity, users have more confidence and believe that their data will not be stolen or manipulated.


Decentralized apps rely on a blockchain to store sensitive data. So, they can shield against any intrusion by anyone trying to alter the data to steal money or censor the content.

Payment processing

With DApp, there is no need to integrate with a fiat payment provider to accept funds from the users, as they can transact without delay using cryptocurrencies.


As long as the Ethereum network remains active, Dapps built on it will remain active and usable. You don’t need to provide real-world identity to deploy or interact with DApps.


While a blockchain offers many advantages to DApps, there are also different downsides:

⚫ Human Error: Smart contracts are written by people and can only be as good as the person who wrote them. Unfortunately, Human errors are unavoidable, immutable smart contracts have the potential to compound errors into big problems.

⚫ Exploits: Openly auditable smart contracts can also become attack vectors for hackers since they can view the code to find exploits.

⚫ Scalability: In most cases, the bandwidth of a Dapp is limited to the blockchain it resides on. For example. If a blockchain can only process 10 transactions per second. The Decentralized app would have to cope with that limitation. When one DApp uses too many computational resources, the entire network receives backed up.

DApp Example

Bitcoin itself is a Dapp, well, it surely rose above the trouble of centralized flow of money transfer and approves you to transfer currency without the need of an authority to ensure transaction validity. This feature itself allows it to be known as a decentralized application. And another similar example is Ethereum. So at this point, you may be excited to start using DApps. There are over 2,000 DApps available in the market at the moment and the industry is growing at a rapid pace. You can even experience the decentralized world of Dapps by using platforms like Trustwallet and Dapp Pocket

Types of DApps

Type 1:

DApps have their own blockchain, for example,  Bitcoin. and other alternative cryptocurrencies with their own blockchain fall under this category.

Type 2:

 This type of decentralized d app leverages the blockchain of Type 1 apps. These decentralized apps are protocols and have tokens necessary for their functioning. The Omni Protocol is the best example of a Type 2 application.  Omni is a distributed trading platform developed on top of the Bitcoin blockchain as a ‘layer’  to facilitate ‘peerless, trustless, and effortless’ exchange of assets or value between parties without involving middlemen.

Type  3:

 The type 3 dApps use the protocol of the Type 2  applications. The SAFE Network (where SAFE  stands for Secure Access for Everyone) is an example of a Type 3 dApp. It is a decentralized data storage and communications network that replaces data centers and servers with the additional computing resources of its users. 

Decentralized Apps vs Traditional Apps

Application is one which every business person uses to reach more users and to cover customers even through mobile phones by which they can enlarge their business. But, Dapp or decentralized application is one that works on the concept of decentralization. ie., in DApps there will never be any central control, and the authority is distributed to all. An app requires an intermediate to connect the user’s wit application. But, DApps does not require any intermediate and it connects with users automatically. An App is always under the control, and developers or owners only can make changes in codes and functionalities. But DApps changes codes and functions automatically and it resists the involvement of developers.

for ease of understanding, you can think of a blockchain as the internet, smart contracts as the World Wide Web, and decentralized applications as websites like YouTube or Facebook.
