What are dApps?

Decentralized applications (dApps) are digital programs or applications that run on a blockchain or peer-to-peer (P2P) network of computers rather than on a single computer. DApps (also known as dApps) exist outside of the control and jurisdiction of a single authority. DApps, which are frequently constructed on the Ethereum platform, can be used for a wide range of applications, including gaming, finance, and social media.

A normal web app, such as Instagram or Bolt, runs on a computer system owned and maintained by a company, allowing them complete control over the app and its functionality. On one side, there may be several users, but the backend is managed by a single entity. DApps can run on either a peer-to-peer (P2P) or a blockchain network. uTorrent, Tor, and others, for example, are software that run on computers that are part of a peer-to-peer (P2P) network, where numerous participants are consuming, feeding, or seeding content, or doing both roles at the same time.

In the context of cryptocurrencies, decentralized applications (dApps) run on a blockchain network in a public, open-source, decentralized environment, free of any single authority's control or interference. Once something is posted on dApp, nobody can delete these messages, while on Instagram for example they can be removed.

A single corporation owns a centralized app. A centralized app's application software is stored on one or more company-controlled servers. You'll engage with the app like a user by downloading a copy of it and then submitting and receiving data from the company's server. Most known such applications are Facebook, Twitter, Uber, …

A decentralized app is a computer program that runs on a blockchain or peer-to-peer network. Instead relying on a central authority, it allows users to conduct transactions directly with one another. The user of a dApp will pay a cryptocurrency fee to the developer to obtain and utilize the program's source code. A smart contract is a type of source code that allows users to perform transactions without disclosing personal information. Most known such applications are Peepeth – alternative to Twitter, Cryptokitties – dApp game.

Advantages of dApps are:

-        Program’s ability to safeguard user privacy.

-        They use smart contracts to make a transaction between two sides.

-        Free speech makes possibility for them to be alternative to social media because such platforms would be without censorship.

-        Rapid deployment of dApps is possible, because everything is based on Ethereum’s blockchain, which will also allow them to be I multiple sectors like gaming, finance, social media etc.

Disadvantages of dApps are:

-        It is still in development.

-        They are experimental, which means that they may not be able to scale.

-        Since it is on blockchain, it is not user friendly.

-        It is difficult to make modifications to a code.
