Formal environment of Ethereum DAPP

1. Ethereum is a new and open blockchain platform, which allows anyone to build and use decentralized applications running through blockchain technology in the platform
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 new and open blockchain platform, which allows anyone to build and use decentralized applications running through blockchain technology in the platform. Like bitcoin, Ethereum is neither controlled nor owned by anyone - it's an open source project created by many people around the world

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

3. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)

4. DAPP is a kind of application program for centralized call, and spiderstore has launched thousands of dapps based on smart contract

5. You can download a "coin listening" app, a live answer software. They will share 12 questions every day, and the questions in it are knowledge related to blockchain. A must for beginners! I'm also learning. Let's refuel together~

6. DAPP is short for decentralized application. App we all know that the app we install on our smartphone is app. DAPP has one more "d" than app, which means distributed. So, it means decentralized applications / decentralized applications< br />


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.

7. We see a lot of information about the blockchain on the fast online blockchain. The blockchain will transform the information internet into the value Internet. At the same time, fast online has accumulated a lot of experience in these technologies and made great efforts in the development of Internet finance. Fast online through research, blockchain will greatly improve the current life scene. What scenarios can blockchain be applied to? Here are some answers for reference only:
1. Information security
2. Food safety
3. Information security
1. Identity protection
2. Data integrity protection
3. Key infrastructure protection
4. Financial instry
1 Digital currency: improve the convenience of currency issuance and use
2. Cross border payment and settlement: realize point-to-point transaction, rece intermediate costs
3. Bill and supply chain financial business: rece human intervention, rece costs and operational risks
4. Securities issuance and transaction: realize quasi real-time asset transfer, accelerate transaction clearing speed
5 Customer credit investigation and anti fraud: rece the cost of legal compliance and prevent financial crimes
6. Equity crowdfunding: equity crowdfunding based on blockchain technology can achieve decentralized trust and ensure the return of investors< 5. Supply chain management 6. Government affairs management 1. Election 2. Government affairs service

8. DAPP has been highly expected since its birth. Relying on Ethereum, EOS and other public chain platforms, many development teams have released a large number of dapps. However, on the whole, DAPP is in its early stage, and its development is still in a dilemma. It has been five years since Ethereum published its white paper in 2013, and the number of dapps has reached more than 1000. On the new generation of public chain represented by EOS, the number of dapps is still rare
these dapps generally have many problems, such as less daily active users, weak foundation and so on. But in the instry, it is generally expected. Compared with the development process of app, instry insiders said that DAPP still needs to overcome several difficulties in the future, such as stable and efficient public chain, developer ecology and user threshold. DAPP is now regarded as an important way to promote blockchain to ordinary people. It is not realistic to replace app with the current development speed of DAPP
however, if DAPP gives full play to its advantages in some areas, it will still pose a certain threat to app, which also depends on the development of blockchain. Dappdiscovery is also based on the present, starting a series of DAPP reports, DAPP market analysis, and the most fun DAPP game evaluation, trying to bring interesting and informative content sharing to all users.

9. The main function of Ethereum is DAPP.
