GC blockchain official website

1. At present, there are not many videos on the market for systematic learning of blockchain, and self-learning of blockchain is still relatively rare. You can apply for classes. Black horse programmers will open a new blockchain discipline. Teachers will teach in an easy-to-understand way and explain in simple terms. You can certainly learn it.

2. Go language + blockchain training course:
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 systems, and concurrency processing is relatively good, such as advertising and search, which are high concurrency servers
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.

3. 2019 is a year of rapid development of bitcoin derivatives, especially in the second half of the year, major exchanges rush to launch futures contract trading, it seems that spot trading + futures trading has become the standard configuration of exchanges. When the market procts are highly concentrated, the market competition is very fierce. The contract market is in full swing, and the vast majority of market shares are held by bitmex, okex, fire currency and other exchanges. As a result, the contract market share is getting smaller and smaller. If you want to win a place in the derivatives market, you have to work hard in proct research and development, which is bound to break through the current market pattern

although the futures contracts were launched last year, for the bitcoin derivatives market, futures alone is obviously not perfect, and there is a huge space for the bitcoin derivatives market. However, bitoffer exchange aims at the bitcoin derivatives market, relying on the advantages of the top financial R & D team, It is the first to launch bitcoin options and bitcoin ETF funds in the world, which is favored by the majority of users<

Lucian, chief analyst of bitoffer exchange, said that BTC options and ETF funds were launched to make up for the current vacancy in the bitcoin derivatives market. What other exchanges can't do is for us to do. The launch of bitcoin options and ETF is not only the improvement of the bitcoin derivatives market, but also a performance of promoting the development of the market. Any investment market can not do without derivatives, because investment is certainly risky, and derivatives can be used as risk hedging tools<

Lucian also revealed that bitoffer is currently developing and building a new bitcoin futures contract trading in the instry, which is expected to be launched in the first quarter of 2020. It is worth noting that the platform has been launched for spot, options and ETF fund trading. If the futures contract trading is launched in the first quarter, it means that, Bitoffer will become the world's first exchange with a full range of bitcoin spot and derivatives routes. By then, bitoffer is bound to win a place in the derivatives market!

6. GCTO knowledge chain is a financial platform using blockchain and artificial intelligence technology. According to my further understanding, this GCTO knowledge chain is a major innovation in finance. It may restructure the global financial system and enable people to enter a new era of intelligent finance. I think it can bring important impact on social economy.. You are satisfied with my answer. Take it

7. Compared with the development prospects of middle and high-end account managers and management trainees, management training should be reliable, because the position of high-end account manager is a bit difficult for fresh graates. If you want to be qualified for the position of middle and high-end account manager, you need to have enough working ability instead of social background.

8. Management trainee: to put it more popularly, it's called reserve cadres. It's a special project in foreign enterprises with the main goal of "training future leaders of the company", referred to as Mt. In every year's school recruitment, fresh students who enter the company as MT will receive various training in the company, and then go through 1-2 years of job rotation. Finally, through the two-way selection of the Department and MT themselves, they will decide their future jobs. Note that the final job is management

What are the advantages of management trainee compared with ordinary position
first of all, position advantage. MT's final fixed post is the leadership post, while other ordinary posts in the school recruitment are only grass-roots posts. For example, in a public relations company, the position of MT is senior customer executive after the post is fixed, while other students recruited by the university need to start from customer assistant. Under normal circumstances, it takes 2-3 years to achieve the position of Senior Customer Executive
for this reason, enterprises are very strict in the selection of Mt. generally, the candidates who can stay are the best among the candidates
the second is the advantage of salary. Because the position will be higher than the ordinary position, the high salary is also natural. Instry rumors, Procter & Gamble, Mars and other FMCG company's MT salary is about 15K, after the post will be increased. The salary of general position graates: 5K for undergraate and 6K for graate. This gap is really not a little bit good
how to become a management trainee
since MT is so good, everyone is Mt! MT's competition is really not generally fierce, OK
first of all, not every company's MT is very good. We only suggest that you invest in MT of big companies
now, because the concept of MT is very popular, some small companies attract candidates to submit resumes under the banner of Mt. in fact, they just recruit them to do chores. Therefore, we need to shine our eyes, and MT should recognize big enterprises
secondly, the ecation threshold is high. The MT of general big enterprise all requests to have graate degree, it is this barrier alone to get rid of a lot of people. Dao Jie had talked with HR of a bank before. Although they didn't specify that they only accept graate ecation, the order of their preference is: graate students from the top 200 universities in the world & gt; Graate students of Peking University and Tsinghua University & gt; Other well-known 985 university graate students in China. To be honest, there are few opportunities for undergraates
again, according to HR, when selecting foreign postgraates, they also have the order of preference. The most popular postgraates are those from well-known universities in the United States, followed by those from France, Germany and Japan, followed by those from Australia, and the most popular ones are those from domestic universities and those from the United Kingdom. Now HR generally believes that British postgraates have only one year to adapt to the language environment, so their professional study time is very small. Except for the top five British University Postgraates, other British university postgraates are generally not considered

finally, after passing the resume screening barrier, the employer will examine MT's comprehensive management ability. Here, we need MT to know the instry situation of the target enterprise very well, have a keen view of the market, have a certain degree of familiarity with the business or procts of the target enterprise, and have insight into team management. Therefore, the interview of MT is very strict, and students who want to become MT need to be well prepared in these aspects mentioned by Daojie.

When calculating the year-on-year growth rate, if the value of the previous period is 0, the growth rate is 100%. Generally, in this case, only the growth value is considered, because the previous value is 0, so it is meaningless to consider the growth rate

the same period ratio of an indicator = (the value of an indicator in the current year - the value of this indicator in the same period of last year) / the value of this indicator in the same period of last year

that is: year on year growth rate = (index value of the current year - value of the same period of last year) ÷ The same period last year * 100%

According to the demand of wholesale market price analysis, the month on month ratio can be divided into day on month ratio, week on month ratio, month on month ratio and year on year ratio

the current month on month growth (decline) rate (%) = [(current price / previous price) - 1] * 100%

note: if the calculated value is positive (+), it is called growth rate; If the calculated value is negative (-), it is called the rate of decline

extended data

calculation formula of year-on-year growth (decline) rate in the current period

year on year growth (decline) rate of the current period (%) = [(current price / price of the same period of the previous year) - 1] * 100%

note: (1) if the calculated value is positive (+), it is called growth rate; If the calculated value is negative (-), it is called the rate of decline

(2) if the current period refers to the current day, the current week and the current month, the corresponding period of the previous year refers to the same day of the previous year, the same week of the previous year and the same month of the previous year

The difference between the year-on-year growth rate and the growth rate:

Description: (1) the year-on-year growth rate means the growth rate in another way

(2) the year-on-year growth rate has a specific time limit, unlike the growth rate, which has a wide range and broad definition. The year-on-year growth rate generally refers to the growth rate compared with the same period of last year
