Decentralised applications (DApps) are digital programs or apps that use smart contracts, operate on blockchains, and run on peer-to-peer networks as opposed to centralised servers. They provide a wide range of services and activities, from gaming to financial, social networking, and much more while they appear and feel similar to regular mobile applications on your smartphone.

security

All DApp data is cryptographically encrypted and kept on a public, decentralised blockchain that is maintained by many users in order to assure data security (or nodes). Thus, it is very hard for the hackers to take over the system.

‍

open-source

‍DApps are open-source, which allows anybody to access, verify, use, copy, and edit their source code. DApps are built on distributed networks without central authority. The vast majority of its currencies or tokens are not controlled by a single company. Users are also able to suggest and vote on DApp modifications.

‍

token system

‍DApps can be accessed by the use of a cryptographic token. They can use native tokens created using a consensus mechanism like Proof of Work (PoW) or Proof of Stake (PoS), or they can adopt cryptocurrencies like ETH as payment without integrating third-party payment providers. By utilising smart contracts, developers can quickly include cryptocurrency into their basic functions. Additionally, contributors like miners and stakers can be rewarded with the token.

personal data control

‍Users can have greater control over the information they disclose because of the decentralised nature of DApps. They don't need to provide a real-world identity to communicate with a DApp because no corporations are in charge of the users' personal data. Instead, individuals can connect to DApps and completely control what information they reveal by using a cryptocurrency wallet.
