Ethereum deploys public chain

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"

2. The digital currency

issued based on Ethereum public chain should be observed according to the price trend of the platform.

3. Ethereum blockchain has exposed three major problems, and its founder vitalik buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied 20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.

4. Many blockchain projects are developed on the basis of Ethereum's open source technology. Ethereum is a common public chain technology, and the deployment of applications on Ethereum has high requirements for developers. Developers need to consider many technical details and business processing logic, as well as security vulnerabilities such as smart contract overflow
the trust union credit alliance chain is located in the financial public chain, which is oriented to the high-frequency financial application scenarios in the field of credit and assets. It does not use eth, EOS, Neo and other general public chains, but uses the account structure of star network, adopts the lightweight intelligent contract layer, and the whole technical architecture is molarized according to "high aggregation and low coupling", This enables the trust union credit alliance chain to adapt to the requirements of rapid development, rapid implementation and timely response of Internet financial procts.

5. Build / env.sh go run build / ci.go install. / CMD / geth
make: * * [geth] error 1
there is no such directory, or the directory has insufficient permissions

6. Yes, but it is better to use overseas servers. In addition, the server configuration should be medium or above.

7. Buy a lot of bitcoin and let it continue to buy high and sell low. If you can hold on, bitcoin may be short
as long as you can continuously spread the shortcomings of bitcoin and rece the number of people who hold bitcoin, it will basically affect the operation of the exchange. If bitcoin can't be traded, it will only have some academic research value

According to the data of okcoin, a well-known digital asset trading platform in China, yesterday, the opening price of Ethereum was 1463.00, the highest price was 1545.00 and the lowest price was 1451.01, closing at 1490.99. The closing price rose by 1.85% and the amplitude was 6.48%. Today, Ethereum opened at 1487.29, basically flat

According to analysts of okcoin, the price has shown signs of strengthening in recent trading days, with the price moving up at the low point of each adjustment. At present, the price is in a high consolidation, most of the time trading in the 1480-1530 range

To sum up, the 4-hour moving average system tends to be long, and the MACD index runs in strong regions, so it is more likely that the intraday price will continue to rise after a small adjustment. Focus on 1460 first-line support within the day. If the price stops falling and rebounds near this price, it means that the market is still strong. If it falls below this price, it will weaken, or test 1420 first-line long short watershed again

NASDAQ has entered into an agreement with major Swiss stock exchange operators to integrate blockchain into OTC procts and services. According to an application document released by the US Securities and Exchange Commission, NASDAQ, which has been studying blockchain technology since 2015, has reached an agreement with six Swiss Exchange, a subsidiary of six group. It is worth noting that six group is also testing blockchain technology through its SiC securities business line

the SEC document said: "in July 2017, NASDAQ signed an agreement with six Swiss Exchange to implement a solution based on distributed ledger technology for six OTC procts, and further use the NASDAQ financial framework (NFF) to promote the commercialization of blockchain technology

although it is not clear when the OTC solution will be developed and whether the deployment timeline has been formulated, this news is the latest progress of NASDAQ in promoting the commercialization of blockchain

for other blockchain projects of NASDAQ, in May this year, the stock exchange and financial giant Citibank reached a cooperation to jointly carry out blockchain payment research. Earlier, in March this year, NASDAQ revealed that it was providing blockchain technical support for a digital media contract exchange

In addition, NASDAQ also expressed its desire to invest more blockchain start-ups, and plans to invest tens of millions of dollars

NASDAQ is one of the most active exchanges in the field of blockchain in the world. In addition, the London Stock Exchange, the Hong Kong Stock Exchange and the New York Stock Exchange have publicly developed blockchain solutions. Not long ago, the London Stock Exchange, one of the world's four largest exchanges, announced its cooperation with IBM to create a blockchain securities platform for small and medium-sized enterprises. The Hong Kong Stock Exchange also announced the launch of a blockchain private stock exchange in 2018

9. 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.

10. There is no doubt that Ethereum is still the absolute head of the public chain in the defi market, but it has passed the situation of Ethereum dominating alone, and the attack of coin an intelligent chain is still very fierce.
