Ethereum familiar with copyright 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.

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

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

4. Basically, the principle is the same. Take baopin.com as an example, baopin.com's video blockchain authentication is actually DAPP. First, it takes a screenshot of the video's key frames per minute, then transcodes it into a string of unique numbers, and then uploads and records it into the Ethereum blockchain.

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

7. The Ethereum community calls smart contract based applications decentralized apps. DAPP's goal is to make your smart contract have a friendly interface, plus some additional things, such as IPFs (decentralized network that can store and read data, not from the Ethereum team, but with a similar spirit)
DAPP can run on a centralized server that can interact with Ethereum nodes, or on any Ethereum node. Different from ordinary websites, DAPP can't run on ordinary servers. They need to submit transactions to the blockchain and read important data from the blockchain instead of the centralized database.

8. It doesn't matter if you can't go to the North Pole. As long as you have money, you can buy ready-made ore smelting. That's also up.

9. It's not difficult. I'm good at it
