Decentralized DAPP Download
1. Different network architectures:
decentralized application (DAPP) runs on the distributed network, the information of participants is protected (or anonymous), and the decentralized operation is carried out through different people in the network nodes. Distributed network is made up of node computers which are distributed in different places and have multiple terminals. When any line in the network fails, the communication can be completed through other links, which has high reliability
traditional app needs services provided by third-party service providers, and can achieve wireless network access through mobile communication network, which belongs to the centralized network architecture mode
2. Different from open source:
DAPP applications must be open source. Most of the tokens issued by DAPP run independently rather than controlled by an entity. All data and records must be encrypted and stored on a public and decentralized blockchain
traditional app software, games, navigation and other applications are generally provided by third-party service providers, which should solve the problems of right protection and economic interests, and their programs are not open source
extended data
in 2018, a large number of new DAPP projects were launched. According to the statistics, there are about two or three thousand dapps in the whole network. According to the DAPP survey of fluence labs, 72% of DAPP projects were launched in 2018. This means that in the past year, the number of dapps in the whole network has more than tripled
of all dapps, more than 80% are developed on Ethereum, about 20% on EOS and less than 10% on Tron. It is worth noting that about 10% of the projects are developed on multiple main chains at the same time, while the number of dapps developed on other main chains is relatively rare
there are about ten projects based on gxchain, mainly small applications in block city
DAPP is an Internet application. The biggest difference between DAPP and traditional app is that DAPP runs on a decentralized network, that is, a blockchain network. There is no centralized node in the network, which can control DAPP completely. As we all know, app is centralized. Need to request a server to get data, process data, etc
compared with DAPP, blockchain is the underlying environment for application running. It can be compared to IOS, andorid and other mobile operating systems running on various apps. Learning blockchain is not the bottom part of learning blockchain. Maybe more people need to learn the development of DAPP. Build and run applications in the blockchain environment< br />
a complete DAPP needs to meet the requirements of completely open source and autonomous applications. DAPP cannot be changed once it is deployed. The upgrade of the application can only be carried out after most users reach a consensus. All data must be encrypted and stored on the decentralized blockchain application platform. Secondly, DAPP must have token mechanism
DAPP can be fault-tolerant without single point of failure. They don't have centralized institutions to interfere. There will be no deletion or modification of some data. It can't even be shut down. Because the data is encrypted storage, there will be no user data leakage events like Facebook and Google
of course, at present, most DAPP procts are still in the experimental stage. Although blockchain technology has brought us a lot of imagination, the specific implementation of DAPP procts still needs to consider a lot of relevant factors.
DAPP is the abbreviation of Chinese distributed app for decentralized application
a DAPP has background code running in a distributed peer-to-peer network. The background code of traditional app is running on the centralized server
the front-end code of a DAPP can be developed by any language, just like the traditional app. In addition, DAPP's front-end code can be hosted in distributed storage services, such as swarm or IPFs
If an application = front end + back end, because Ethereum contract is composed of code running in Ethereum distributed point-to-point network, distributed application = front end + contract
the picture shows a DAPP architecture:
app we all know that it is a client application, which is the abbreviation of application. DAPP is d + app, and D is the first letter of English word decentralization. Chinese word translation is decentralization, that is DAPP is decentralized application. This is to understand the concept literally. To form a clear, accurate and necessary concept in the brain, we need to understand DAPP in depth
compared with app, the biggest difference between them is centralization and decentralization. App needs money first, so it needs financing first; Then there will be more people, so we will develop and operate after recruiting all the people. DAPP is the proct of inheriting traditional app and combining the characteristics of blockchain, which is more like crowdfunding mode, sharing mode and decentralization mode
