Blockchain training fabric

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. It is recommended that Guoxing blockchain business school has a good reputation in the instry, which can enhance the competitiveness of enterprises, so it is recommended.

The deposit fee of 100 yuan for registration can be returned after completing all courses

tutoring class was given under the line, and the lecture lasted for 4 days, with 7800 yuan per person

RMB 88888 per person for 3 days and 2 nights

What is

...

blockchain? Maybe few people can really answer this question. It is precisely because of the inherent mystery of "blockchain", that many people are eager to pay for knowledge in order to get on the train to the "future"

therefore, all kinds of blockchain training are also very popular, and all kinds of information, such as "scanning code, entering the group to listen to lectures", are filled with the circle of friends, so it is difficult to distinguish the good from the bad. The training costs are even more uneven: 100 yuan, 300 yuan, 7000 yuan or even nearly 100000 yuan...

blockchain training is too hot

I often make up my identity on the dating materials, such as import lighting wholesalers, urban landscape designers, boutique tobacco hotel owners and agricultural loan salesmen. Now, I have finally become an expert in blockchain training courses

} photo source: a screenshot of a recruitment website

and it is reported that a blockchain recruitment advertisement in Beijing recently blew up the circle of friends, requiring candidates to have in-depth research on blockchain technology and cryptography, giving an annual salary of not less than 5 million yuan, and not capped

"this is really the current situation of blockchain talent recruitment. But even so, we can't find people, because it's hard to find qualified people. " Lu Sheng, head hunter of Liepin platform, said

Song Mofei, senior researcher of Suning Institute of finance, said: "in terms of development experience, the rise of domestic blockchain instry has been concentrated in the last two or three years, and few people have long-term blockchain development experience in the talent market." He believes that excessive salary will inevitably attract some speculators, but the increase of salary does not bring about the increase of the application threshold, and even some recruiters only know a little about blockchain technology, which also poses new challenges for the recruitment of blockchain talents

according to Shan Yi, chief data officer of liepin.com, the core of blockchain is the change of social relations and business model based on Internet distributed trust system, which is characterized by decentralization“ There are still many uncertainties in the future development of block chain. There are obvious bubbles at present, and many block chain projects are not reliable. He said

4. Recommend Hong Kong Institute of international new economy chain energy institute
in order to better promote the application of blockchain in real economy, Hong Kong Institute of international new economy has arranged "chain energy institute" + "chain energy capital" + "chain energy instry alliance", and established an ecological environment of self-development and self evolution of chain energy economy
chain energy college is an academic research and ecational institution focusing on economic theory, business model research and chain energy training ecation. It is the "brain" and theoretical pioneer of chain energy economy

as the proponent of "chain energy economy", the Hong Kong Institute of international new economy is committed to providing government regulators and traditional Chinese entities with new financial economy, blockchain technology and popularization of the theoretical system of "chain energy economy" and related solutions.

5. I think hashton is not bad. They have landing service, which can also help improve the competitiveness of the enterprise. That's where I learned it.

6. I have studied in black horse Shanghai, according to the lowest and you say it, the highest consumption, you can spend. For accommodation, the school is 450 or 550, which corresponds to six or four rooms. With the electricity charge, the minimum is about 550 (instrial electricity) per month. If you have a canteen, you can have a good breakfast at 5 yuan, 9-15 yuan at noon, and the same at night. If you eat 25 yuan a day, it's not much wrong, so you need 750 yuan a month. In fact, it's not very expensive, because this is a suburb, and the consumption in Shanghai is already very low.

7. Many projects belong to the new infrastructure category. Just take the procts and solutions launched by lierda group as an example: (information communication, 5g and other infrastructure network construction) lierda lorawan solution has low power consumption, strong anti-interference, low cost and high capacity; Lilda NB IOT solution has wide signal coverage, strong penetration ability, ultra-low power consumption, ultra-high sensitivity, strong anti-interference and low cost Smart city, municipal pipe network) has a mature underground parking energy-saving lighting system to rece lighting costs, system rability and reliability, save maintenance costs, improve management efficiency Artificial intelligence) Intelligent Hotel solutions meet the personalized needs of customers and make the hotel management service more efficient and orderly

8. Because there are a lot of rich and powerful people heating up.

Yes π Currency is not Wu currency. π Money is MLM

the list of MLM currencies confirmed by the judiciary (37 were monitored in the second half of 2018):

grdc, Yan, DGC virtual currency, EGD super, Tianhe, u treasure, huangzun“ π”、 Yayuan, prize gold coin, Wenmou (virtual currency), Shengyuan, Shitong yuan, Zhongyuan, Kela, yunxun Tong (declaration currency, Shuanghui currency and Wuxing currency), goupai currency, Baote currency (TRC) and Locke currency (RKC)

e coin, ADC, BTM Bart coin, LCC coin, Vicat coin, yunzun coin, Yunjin coin, CNB, air bitcoin Club (ABC), code chain, touch gold pie, environmental protection agriculture chain (NYC, Ctop), IAC, liangbisi, Eurasia coin, (Jianye coin, Jinxiangyu), Walker financial management, Wanfu coin

among them are π Money

purchase virtual currency on "SCI" financial platform“ π” Invest in Macao gambling instry to get dividends, require participants to pay 100 yuan declaration fee, get the registration code to register as a member, and then buy a minimum of 50 π， Investment can be made by developing offline procts π Carry out Commission

The basic rules of MLM money are as follows:

1. MLM leaders set up shell companies and websites at home or abroad, and usually set up charities, financial management, games, medical research, etc. to establish public initial trust

2. Through wechat, QQ group, lectures and other forms, we vigorously publicize the value of a certain "virtual currency", and some even use special public relations for online whitewashing to dispel members' doubts

3. With "high rebate" as a gimmick to attract many people's participation, the business model is usually "pay the entrance fee", "pull the head" and "form a hierarchical team to pay" to continuously absorb membership es to achieve the purpose of making money, the specific form is as follows:

1) pay the entrance fee or pay the entrance fee in disguise, That is to say, you can get the "qualification" of withdrawing remuneration or developing offline only after you pay for joining

2) direct or indirect development of offline, that is, pull people to join, and form a hierarchy according to a certain order

3) the on-line company shall calculate the remuneration from the sales performance of the off-line company directly or indirectly developed, or calculate the remuneration or rebate based on the number of personnel directly or indirectly developed

4. In the end, because there is no offline to join the project, the project members can't convert the digital token into cash, and the capital chain is broken

in this monitoring and collation, the research team of LinkedIn app noticed that after a period of silence, the MLM coins that had been warned and exposed appeared again in the second half of 2018. The MLM team either moved to the development area, or changed the name of the MLM coins that had been warned, and continued to carry out MLM with the same operation means and similar channels of transmission

10. Take subway line 8 to people's Square, transfer line 1 to Jinjiang paradise station, transfer to "Shimei line"

take subway line 8 to people's Square, transfer line 1 to Lianhua Road, get off the station and cross the overpass. You can take "Lianshi line" to Petrochemical bus station and get off. It's very close
I took this line once and felt very far away. I walked for 1-2 hours that time
