Definition: What is a Dapp?
To understand what a Dapp is we have to understand its meaning since when we talk about Dapps Development Company or decentralized applications we refer to a type of application that does not depend on centralized servers (AWS, Google Cloud) but rather its operation depends on a decentralized network.
These Dapps can be used, just like conventional applications, on computers and PCs, smartphones or web pages.
Some examples of centralized apps can be Telegram, Spotify or Netflix. In all these services, decisions and data and analytics are 100% in the hands of the companies. The user has no power of decision or governance over the platforms and they can only trust them.
The “Boom” of the Dapps.
The concept of DApps did not have such relevance until the arrival of Ethereum in 2014 and Solidity, an Ethereum programming language that allows the execution of smart contracts in the EVM- Ethereum Virtual Machine.
The use of Dapps has opened up an unprecedented range of possibilities in the technology, finance and gaming sectors in recent years.
DApps vs Apps. Differences. What are its advantages?
The reality is that DApps and Apps share many common components. However, there are nuances in how they interact with those components: Frontend, Backend, and data storage.
Frontend:
When we talk about the frontend (be it a Dapp or an App) we refer to the interface that users use to interact with the application. The purpose of this layer is to give the user the power to send and receive information from the application used.
For example, when we want to book a room in a hotel through its website or search for a flight in an app, we are interacting with the frontend of the solutions.
Backend:
This layer refers to the main logic of the application. In a 2.0 environment, this logic is centralized, unlike DApps where it is decentralized.
In DApps, the backend is associated with a smart contract that runs on a blockchain. Smart contracts are 100% visible and public, this guarantees a high level of transparency and security for users who interact with these DApps.
Data storage:
In a 2.0 application, data storage is also centralized. As a general rule, this data is stored on the user's device or on external servers controlled by third parties. This can cause some inconvenience as all data may be lost if it is being stored on the device or the servers are temporarily down and we cannot access the app. In DApps, the associations are put away in the blockchain. All this in a cryptographically secure way, preventing access to unauthorized persons.
