Decentralized Application (DApp) is an application software. It is somewhat similar to a smart contract. But it has a number of fundamental differences. For example, DApps are not directly related to financial transactions. But they provide the ability to use the blockchain architecture for absolutely any purpose.
The overwhelming majority of users with experience with blockchain-based platforms know that a smart contract is a decentralized thread. It links two or more parties in a blockchain. Smart contracts, widely used in the modern world, need constant material support. And it contains a number of restrictions. For example, they strictly control the number of participants per unit of time. Decentralized Application (Decentralized application). It offers a similar technology. But only in a more sophisticated form.
Decentralized applications can be used for completely different purposes. However, all DApps can be divided into two main groups:
- completely anonymous programs;
- reputation-dependent applications.
Anonymous applications are able to guarantee absolute confidentiality. When using them, all actions are automatic and performed as quickly as possible. Perhaps the most obvious example is the BitTorrent client. It is familiar to almost every PC user. This software uses the technology of decentralized anonymous applications. It’s working in a peer-to-peer peer-to-peer network. It allows users connected to the platform to exchange files of different sizes, spending a minimum of time.
Reputation dependent applications are software where each node can be tracked by a user to check its status. The maximum level of trust is a fundamental condition under which decentralized applications dependent on reputation can function. At the same time, in a program based on reputation, it is impossible to assign any material value depending on the level of trust. And also, it cannot be transferred from user to user.
Decentralized technologies will be at the heart of the next generation Internet. Popular entertainment apps on the web are already moving to blockchain. Why do they need a blockchain? And what is the peculiarity of using a distributed ledger in this area?
Decentralized applications: essence, advantages, disadvantages
The full transition of the Internet to decentralized app development at Unicsoft is still far away. But more and more projects and services are abandoning a single center in order to automate work. It iimproves security and make their activities transparent.
DApp is an application that operates without a backend, in a distributed computer system (for example, a blockchain). It uses its power and taking over all the advantages. With their help, you can store information, create smart contracts and perform various operations with tokens.
The main advantages of dApps include:
- instant interaction and data exchange;
- the absence of a third party in the processing of payments and personal information;
- open source;
- high stability and reliability of the system;
- open access to the registry.
However, this technology also has its drawbacks. Since decentralized applications run on the blockchain, they are completely dependent on its stability. Like any network, each distributed ledger has its own limits. So overloads and performance degradation are possible. It is also possible to hack the system and change already closed blocks, although in practice this is difficult to implement.
Basically, the first implementation of a decentralized application was Bitcoin. It allows any user to download part of the network code to connect to the blockchain. It helps to mine cryptocurrency. The main feature of dApp is its distributed structure, which provides flexibility and stability of work. As with RAID arrays, if one of the computers (nodes) fails, the others will immediately resume the task.
Below are 10 of the most useful dApps for consumers, go now here. Another advantage of dApp is the interaction with smart contracts. It’s the use which allows you to automate many business processes. And they significantly reduce administrative costs. Smart contracts perform predefined functions.While blockchain provides immutable data storage and transaction verification.
