Steps to link up Ethereum DAPP
just like bitcoin, Ethereum is neither controlled nor owned by anyone - it is an open source project created by many people around the world. Different from bitcoin protocol, Ethereum's design is very flexible and adaptable. It is very easy to create new applications on the Ethereum platform. With the release of homestead, anyone can use the applications on this platform safely
Ethereum is a programmable blockchain. It does not give users a series of preset operations, but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator.

Ethereum is a programmable blockchain. It does not give users a series of preset operations (such as bitcoin trading), but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications, including but not limited to cryptocurrency
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator
like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"
this massive parallel operation throughout the Ethernet network is not to make the operation more efficient. In fact, this process makes computing on Ethereum slower and more expensive than on traditional computers. However, each Ethereum node runs Ethereum virtual machine in order to maintain the consistency of the whole blockchain. The consistency of decentralization makes Ethereum have high fault tolerance, zero downtime, and can keep the data stored on the blockchain unchanged and anti censorship
Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks
for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound
in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale
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
first of all, it must be pointed out that the relationship between DAPP and app is not the relationship between who replaces who or who eliminates who, but the coexistence relationship, or DAPP is the enrichment and improvement of app< Secondly, DAPP is the proct of the development of the times and the progress of science and technology
because DAPP is directly linked to blockchain technology, it is associated with transaction data, transaction assets, and tamperable decentralized storage< In his book decentralized applications, Johnston believes that a DAPP application should meet all the following conditions:
1. An application must be completely open source, autonomous, and no entity controls most of its tokens. The application must be able to upgrade according to the market feedback and technical requirements, but the upgrade can only be carried out after the application users reach a consensus< Second, the application data must be encrypted and stored on the public blockchain
3. The application must have a token mechanism (it can use the existing token or issue a new built-in token), and the miner or application maintenance node needs to get token reward
fourthly, the generation of application token must be based on the standard encryption algorithm, and valuable nodes can get the token reward of the application according to the algorithm
in short, an application running on the public chain in the form of smart contract can be called DAPP. Different from the conventional app, DAPP's logic (source code), stored proceres and stored results are open and transparent, and can't tamper with the storage logic and content< At present, dapps meeting the above conditions include the following categories:
content dapps -
the coupling between blockchain and content vertical field is very good. Using the characteristics and technology of blockchain, there are more and more platforms to do content, and the competition on this track is extremely fierce, such as steemit abroad, currency, Primas, fulcrum, Youxiang, etc Pressone et al<
DAPP for games -
such as the "blockchain cat raising" incident, which was very popular last year. In this game, players can buy, sell and breed different kinds of kittens. The popularity of this game even caused serious congestion of Ethereum network. Now the blockchain game is not limited to the Buddhist pet game, other blockchain Gobang, drifting bottle, card games and so on
with the development of the times and the more mature and popular blockchain technology, DAPP will be paid more and more attention, and more and more dapps will appear in various scenes of life.
