Ethereum, the main chain of blockchain

1.

what is Ethereum:

Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. blockchain technology is one of them
Ethereum platform can safely run any program users want

advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum

what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application

The design of Ethereum is very flexible and adaptable

Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields

blockchain applications of Ethereum

Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc

Ethereum has achieved more than 100 blockchain applications by many start-ups

Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged

the relationship between Ethereum and blockchain:

Ethereum is a programmable blockchain

Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes

in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency

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"

Blockchain 1.0 era usually refers to the development stage of blockchain application represented by bitcoin from 2009 to 2014. They are mainly committed to solving the problem of decentralization of currency and means of payment; After 2014, developers pay more and more attention to solve the technical and scalability problems of bitcoin. At the end of 2013, vitalik buterin released Ethereum white paper "Ethereum: next generation smart contract and decentralized application platform", which introced smart contract into blockchain and opened the application of blockchain outside the currency field, thus opening the era of blockchain 2.0< The so-called smart contract is actually a kind of computer contract that can be automatically executed based on prescribed trigger rules. It can also be regarded as a digital version of traditional contract. It was proposed by interdisciplinary legal scholar and cryptography researcher Nick Szabo more than 20 years ago. This technology was once not used in the actual instry because of the lack of programmable digital system and related technologies, until the emergence of blockchain technology and Ethereum provided a trusted execution environment for it

compared with bitcoin, Ethereum is a complete scripting language of Turing, which supports developers to create and publish arbitrary decentralized applications on the platform. Since its birth, there have been more than 200 decentralized applications based on Ethereum in the world

the chief researcher of bitwindow blockchain said: in the era of blockchain 2.0 represented by Ethereum, blockchain technology has graally expanded from the field of currency and payment to the field of finance. With the development of technology and the wider application of blockchain, the era of blockchain 3.0 beyond the monetary and financial fields will be around the corner. This article is excerpted from bitwindow. China's professional blockchain and digital currency instry analyzes the media, and adheres to a neutral, objective and dialectical attitude to understand and interpret the latest trends of blockchain and digital currency

This is two different concepts. According to different standards, blockchain can be classified into three categories:

& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain

 &# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain

 &# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain

the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process

4. If you want to invest, it is recommended to consider whether you are optimistic about this instry first, because bitcoin, a kind of digital currency, has no real value, only collection value, and all the speculation prices are relatively high. If you want to invest, you should first choose a reliable old platform with good reputation, so that at least the money will not disappear out of thin air. You can take a look at AEX and fire coin, It has been more than 6 years and has a good reputation. For long-term investment, you can go to AEX for money management

5. Don't say ether, even when big pie trading, there are risks. If you want to rece the risk, you need to find a reliable platform and a reliable team, so as to minimize the risk.

6. Jinwowo will focus on blockchain technology to promote the legal circulation and commercial application of big data. The following is the development trend of blockchain in 2018 analyzed by jinwowo:
1. Asia and the Middle East will actively promote blockchain
2. Network security requirements will drive the popularization of blockchain
3 - all instries will fully invest in blockchain application technology
4 - automation and privatization are coming.

7. Many virtual currencies, once withdrawn from the exchange, have to be stored in third-party wallets such as imtoken. This is also forced helpless, because there is no own wallet, so can only "rely on others."
How can we live an independent life without looking at others? This will lead to a word: the main chain
the term "main chain" comes from the "main network" (relative to the test network), that is, the officially online and independent blockchain network
at present, among the top 50 blockchain projects in terms of market value, 12 projects are "main chain" (the current data has changed), and Ethereum is the most successful one
Ethereum is a main chain that has its own independent wallet and can "provide housing" for other currencies
next, through the analysis of Ethereum, we will give you an in-depth understanding of what is the main chain
most of the crowdfunding projects in the market are based on Ethereum. You can understand that Ethereum is a computer operating system, similar to the windows system, and the various tokens on Ethereum are equivalent to all kinds of software on our computers. Developers can pay Ethereum to run projects on Ethereum. However, Ethereum is not perfect. The more projects based on Ethereum, the greater the network demand for Ethereum. In serious cases, it will lead to congestion
in fact, most of the main chain projects are still in the stage of technology R & D and improvement, and there is still a long way to go before the real technology is implemented
the most fierce competition in the field of blockchain is actually the battle of "main chain". Whoever can become the main chain of the basic layer of the blockchain is likely to become the future giants such as apple and Microsoft
in addition, in the domestic public chain, the Walton chain is the underlying commercial application public chain, which combines the software level features of blockchain, such as decentralization and unforgivability, with the hardware of RFID chip independently developed, to provide traceability, authentication solutions, and design instry data encryption and distributed storage database building services for all walks of life
of course, it doesn't mean that projects with a main chain are better than projects without a main chain. Some projects, e to their nature, don't need a main chain, such as BNB, whose main purpose is to offset the handling charges in the currency exchange, so it doesn't matter whether there is a main chain
from bitcoin to Ethereum, and now to EOS, many gods are building the main chain, trying to climb the tide of the times. Who will be the future king of blockchain? Let time give us the answer.

8. Ethereum is also a proct of blockchain 2.0, which is an open intelligent contract complete solution. Bitcoin is the most important application of blockchain 1.0, which completes currency and payment transactions well. But when we need to record and transfer more complex asset types, we need the third step - a more powerful scripting system - to finally achieve Turing completeness (the ability to run any currency, protocol or blockchain). Ethereum is a blockchain based project, which aims to provide a Turing complete scripting language and Turing complete platform

blockchain 1.0 mainly refers to bitcoin. Blockchain 2.0 extends to all assets, while blockchain 3.0 goes beyond currency, finance, even commerce, and all areas of our lives, including politics, social relations, ecation, medical care, etc. According to the prediction and conception of people in the instry, the era of blockchain 3.0 will be realized in the next five years. At that time, blockchain will be recognized and accepted by all the public like the Internet, thus completely subverting our lives

McKinsey has submitted a technical report on blockchain to the Federal Insurance Advisory Committee of the United States. The report calls 2009-2016 the "Dark Age" and believes that all blockchain solutions ring this period are based on bitcoin, and the new era of blockchain will begin in 2016. At that time, the application of blockchain will become unprecedented. Applying an original sentence in McKinsey report: Based on the current development speed of blockchain, we believe that blockchain solutions may realize their full potential in the next five years.

9. The most fierce competition in the field of blockchain is actually the battle of "main chain"
whoever can become the main chain of the basic layer of the blockchain is likely to become the future giants such as apple and Microsoft
it's said that the main chain of Jinyou chain is half finished. At least the direction of blockchain technology is right. Next, we'll wait for them to use the main chain to see the effect on the game platform
I'm still optimistic
