What is the best Decentralized App Development framework?
What are decentralized applications?
They are solutions that are not managed by technology provider companies, and in which their users interact and close agreements directly with each other and without intermediaries. Based on blockchain technology , with an open code that operates automatically and is available to anyone, decentralized app developer they are also known as DApps, for their acronym in English .
In addition, they have a standard algorithm, and require a digital asset to access and use them, which acts as compensation for those who add value to them.
For Coin List they are pieces of software that have a graphical interface, which is executed and managed by various users in a decentralized network. In this sense, it is important to bear in mind that for the user they are similar to any other application, what differentiates them is what happens in the backend, which is not visible to those who use the app. These are collaborative environments , in which there are no central entities that manage the service, and they do not have the control of any institution or government that regulates its operation.
From Blockchainx Hub they maintain that for a software to be considered a Dapp: it must be open source and use a cryptographic token , its data and registration must be stored cryptographically and generated automatically.
While in Davies they identify three categories of decentralized applications :
Type I: they have their own blockchain technology (this is the case of Bitcoin).
Type II: they do not have their own block chain and use that of a type I app.
Type III: They use blockchain technology and the standard algorithm of type II applications.
It is worth noting that the most recommended language for Ethereum , the blockchain platform used to create 80% of DApps, is Solidity , on which the e-Learning Center offers a specialized course .
Examples of decentralized applications
Bitcoin and Ethereum are two clear examples of decentralized applications.
Other solutions that work with this modality, and do not have a central authority that stores information of the parties involved in contracting a service, are (among many others):
e-chat : instant messaging application
Factom : system for data recording
Augur : predictive investment platform
Story – New generation decentralized network that stores content in the cloud.
La’Zooz or Crypto Cribs – Alternatives to Uber and Airbnb, respectively.
CryptoKitties : create virtual pets that can be bred, traded, collected and crossed with other users’ crypto cats, to obtain other unique specimens.
Musician: music streaming platform.
Decentraland – Virtual reality world where territories can be bought, modified, and sold to the highest bidder.
How do decentralized applications work?
Decentralized applications work as follows:
The various DApps share a conceptual scheme, but each uses a different infrastructure.
Each user is a node in a decentralized network.
No one expressly gives their consent, everything works automatically (the system checks the validity of each interaction with a program that executes itself when the conditions programmed in its code are met).
Faced with a new operation, the platform is updated in each node, storing a copy of the entire history of the ÐApp. The distributed nature of a blockchain ensures that if a node disappears, there are many backup copies of the decentralized application. This advantage, however, can also be seen as a problem, since storing large volumes of data in parallel could be expensive.
The two most important parts of developing a Dapp are the performance of the client UI and the smart contract that works as a back-end program.
Advantages of decentralized applications
Compared to traditional applications, DApps provide numerous benefits:
Security. Blockchain encryption allows sensitive user information to be shielded, as it is not centralized in any database.
Comprehensive code analysis . The tests that are carried out before its launch are rigorous and of great quality.
Intractability . The information cannot be tracked by any central entity to know the interests of its users, making it impossible to use personal data for commercial purposes.
Reliability : there are no risks of arbitrary changes to your rules of use or business model without the consent of your community.
Availability . As the application is distributed in nodes, system crashes are considerably reduced, to minimal levels or practically non-existent.
Compensation . Those who contribute to the maintenance and operation of the system, providing computational capacity, benefit from different types of rewards, including digital assets such as cryptocurrencies.
Energy optimization . In the calculations necessary for the execution of the software.
Immutability. It carries its code recorded in an immutable chain of blocks, whose operation cannot be altered or suspended. Modifying a smart contract requires the consent of all the servers on which it is distributed.
