What is a DApp? How does the decentralized app work?

A type of software that does not have a center and works independently of any institution or person is called a decentralized application (DApp). Decentralized software can run on blockchain or peer-to-peer (P2P) networks.


The purpose of developing self-executing DApp systems without anyone's control is to reduce the influence of third party persons or institutions on transactions. Unlike traditional applications, these software bridges between the user and the provider without intermediaries.


Pros of decentralized apps

Blockchain-based DApp solutions that are not managed and decentralized by a certain authority protect against censorship. The probability of transactions being interrupted is very low. Even if some of those who count processing power to the network experience technical problems, transactions can be continued through other providers.


Decentralized applications built on blockchain directly support cryptocurrencies. No additional fees are charged for transactions, as each connected user offers support to the network.


Thanks to their open source structures, developers can implement more efficient applications by getting support and help from each other. Moreover, they are more resistant to cyber attacks compared to traditional server-based centralized applications. The DApp ecosystem has the potential to improve both payment and authentication processes.


The fact that their code is open source and transactions are recorded in a way that is visible to everyone builds trust. Since all data is encrypted to ensure the security of the network, although the accuracy of transactions in decentralized applications can be checked, sensitive information in them can still be stored securely.


Cons of decentralized apps

Although open source structures of DApp projects are advantageous, there are also disadvantages. Malicious people can attack by exploiting the weak points they see in the code that can be accessed by everyone.


On the other hand, projects with low user counts become insecure because the power of DApp networks comes from their users. The more users connected to the network, the higher the security of the network.
