Why does Ethereum use go

1. Go full stack + blockchain course:
a total of 22 weeks, divided into five stages,
the first stage is 4 weeks, go language foundation and network concurrency, learning the introctory go language,
the second stage is 4 weeks, go language practical web development, crawler development, cryptography, consensus algorithm, realizing lightweight public chain, learning the website and crawler that can develop golang, Achieve lightweight blockchain
stage 3, 4-week Ethereum source code analysis and smart contract DAPP development, master Ethereum core and smart contract development, as well as blockchain,
stage 4, 4-week super ledger, bitcoin EOS, source code analysis and smart contract practice, master super ledger development, cat bitcoin, bifurcated EOS after learning, As well as DAPP development of smart contract
phase 5, 6-week project practice, five enterprise level projects, and one year of blockchain project experience after learning
from the characteristics of the language itself, go is a very efficient language, which highly supports concurrency. Go language itself pays more attention to distributed system, and concurrency processing is relatively good, such as advertising and search, That kind of high concurrency server
go language advantages:
excellent performance, can be directly compiled into machine code, does not rely on other libraries, go is extremely fast. Its performance is similar to Java or C + +
concurrency is supported at the language level, which is the biggest feature of go. It is born to support concurrency, and go is the concurrency supported in gene, which can make full use of multi-core and make it easy to use concurrency
the built-in runtime supports garbage collection, which is one of the features of dynamic language. Although GC is not perfect at present, it is enough to cope with most of the situations we can encounter, especially GC after go1.1
it's easy to learn. The authors of go language all have the gene of C, so go naturally has the gene of C. There are 25 go keywords, but the expressive ability is very strong. It almost supports most of the features you've seen in other languages: inheritance, overloading, object, etc
rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.

2. With the development of Internet. The shortage of IT talents will be more and more serious. According to a conservative estimate, the demand for it talents in the Chinese market is more than 200000 every year. The domestic IT ecation is mainly the academic ecation of computer, electronics, telecommunications, information technology and other related majors in Colleges and universities. The annual number of college graates is about 50000, which is far from meeting the needs of the market. I

3. 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.

There is a certain chance to obtain arcane crystal when collecting silver ore through mining skills. The location of the collection points is as follows:

1, hakalaise silver vein, coordinates (58.9, 49.3), (42.7, 77.7), (64.1, 55.7), as shown in the figure below:

fuser silver ore is a mining skill requirement 275, which can collect: heavy stone, big cat's-eye stone Sapphire, giant emerald, Azeroth diamond, arcane crystal

extended data

the role of arcane crystal

1. Transformation: Arcane gold

need: silver ingot, arcane crystal

use effect: transform a silver ingot and an arcane crystal into an arcane gold

2, the

of the shadow of pain

needs: Arcane crystal, necromancer essence (2), demon Fu Wen. p>

3. Arcane st

need: Arcane crystal

use effect: turn an arcane crystal into arcane st

5. OK

take a bus to Zhuhai first

get off at Xiangzhou terminus

get off and then turn to a taxi

it's easier to get lost

6. Zhuhai station will pass by Pearl station! Zhuhai north station is too far away! Go to the Pearl station of the Sports Center recently, after arriving at the station, the starting price is 10 yuan! If not, go to Tangjiawan station, which is better than Zhuhai north station!

7. From Guangzhou to Zhuhai (about two hours):
1. Walk about 380 meters from Wushan Town station to Huanong (South China Agricultural University), where there is a student charter bus to go home, including Zhuhai, and the ticket price is lower, no more than 50 yuan
2. Take a bus from Guangzhou to Zhuhai, and the fare is 60-70.
generally get off at Zhuhai Xiangzhou passenger terminal (Bauhinia Garden) or Zhuhai Gongbei port passenger terminal<

from Zhuhai to Coca Cola Company:
1) bus (within half an hour, 1.5-2.5 yuan): if you want to go to Coca Cola company in Zhuhai, you are advised to get off at Gongbei, take bus No.30 at Wanjia department store, and get off at xiaorongtai branch, where the company is nearby
if you get off at Xiangzhou, take bus No.15 or No.15, Get off at the "zaobei" station
2) take a taxi (within 10 minutes, about 20 yuan), and tell your master that your destination is OK and convenient

address of Zhuhai Coca Cola Beverage Co., Ltd.
No. 88 Daishan Road, Zhuhai City, Guangdong Province

suggest that since you are ready to go to Zhuhai, buy a map, all the information about transportation, tourism, housing and food is complete, only 5 yuan.

8. Zhuhai sports school is in Zhuhai sports center. Take buses from Guangzhou bus stations to Zhuhai, where you usually get off at Xiangzhou and Gongbei, with Gongbei as the destination. The place to get off in Xiangzhou is usually the "huazi Shidong" bus stop (you can ask Bajie when you get on the bus). After getting off the bus, the bus stop will turn to the No.7 bus terminal "Sports Center South" and get off at the Zhuhai sports center.
