What does blockchain DAPP mean
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
Hello, I'm a small naughty bag in the blue ocean of blockchain. I'm glad to be able to answer your question. In your presentation, we have raised two questions, and we will answer them one by one
it can be said that we are still in the exploration stage of blockchain technology. How to apply some technical principles? In other words, how to realize the landing value? It is also necessary for indivials to improve their comprehensive understanding of blockchain through professional learning and training, so as to fully grasp the opportunity
it is suggested that questioners can go to the professional ecation platform like "blockchain blue ocean" to comprehensively improve themselves through science popularization, instry development trend and other aspects
Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:
1, open source code
upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public
2, complete decentralization
anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"
3. Developing decentralized applications
through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers
application, which translates into decentralized application, also known as distributed application. The reason why it is considered to open the era of blockchain 3.0 is that DAPP is different from the app we currently recognize. What is the difference? Of course, its particularity is not limited to "d", but lies in its background, which is blockchain! According to the current popularity of blockchain, everything related to it has become very advanced
here is a very straightforward way to explain DAPP, that is: take out the app that we currently develop relying on IOS and Android system, throw it on the blockchain system, and combine with the smart contract, it becomes DAPP.
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
