区块链是什么意思？区块链是一种不可篡改的、分布式的数据库技术，它可以让不同的用户和组织共享和管理数据。区块链利用分布式账本技术，可以让所有参与者能够访问它们的数据，并且可以保证数据的安全性和完整性。

区块链技术的开发费用可能会因为项目的不同而有所不同，可能会受到诸如技术复杂度、开发时间等因素的影响。开发者可能需要支付技术架构费用、硬件费用、网络费用、软件费用、人员费用等费用。

区块链技术可以让不同的用户和组织共享和管理数据，这样可以减少投入成本，提高效率，并且可以提供更加安全可靠的数据存储和管理方式。因此，许多企业和组织都在投入资源来开发基于区块链的应用程序和服务，以提高数据安全性和效率。

总之，区块链技术开发费用是指用于开发基于区块链的应用程序或服务的费用，它可以让不同的用户和组织共享和管理数据，从而提高数据安全性和效率。许多企业和组织都在投入资源来开发基于区块链的应用程序和服务，以获得更多的利益。

A. Why do some people think that the GO language will become a trend in developing underlying blockchains

Why should we learn the Go language due to the explosion of blockchain?

The demand for blockchain talents in 2018 was 9.7 times that of the same period in 2017. According to statistics from recruitment websites, most positions in the blockchain require mastering the Go language.

Blockchain engineers in the top 100 online jobs are required to be proficient in blockchain protocol development in Go language

B. How long does it take to learn blockchain?

It depends on your basic level. If you have a certain technical foundation and have done development, it will be relatively easier to learn. .
"Lianren Academy" offers short-term weekend technical training courses for colleges with a certain programming foundation. You can check them out and consult about your situation.

C. How to develop blockchain technology? Is it difficult?

Blockchain technology belongs to the software development industry. If the technology is in place, it will definitely not be difficult. Otherwise, it will be difficult if you don’t know anything about it. It’s as difficult as climbing to the sky, you can measure your own level, if not, outsource

D. How to quickly get started with blockchain

Currently there are not many systems on the market to learn blockchain videos, it is still relatively rare to learn blockchain by yourself. You can sign up for a class. Dark Horse Programmers has newly opened a blockchain course. The teacher uses easy-to-understand teaching methods and explains the technology in simple and easy-to-understand terms. You can definitely learn it. Source: AreaTV. If you want to understand blockchain and watch video tutorials, come here!

E. Who is teaching the popular blockchain training course

Sign up and pay a 100 yuan pre-deposit fee, which will be refunded after completing all courses;

Online Tutorials will be given below, 4 days of lectures, 7,800 yuan per person;

3 days and 2 nights, 88,888 yuan per person;

......

What exactly is blockchain? Perhaps very few people can really answer this question. It is precisely because "blockchain" is inherently mysterious that many people are eager to pay to get on board this train to the "future" in order to gain knowledge.

Therefore, a variety of blockchain trainings are also very popular. Various information such as "scan the code to join the group to listen to the class" are flooded in the circle of friends, making it difficult to distinguish the good from the bad. The training costs are even more varied: 100 yuan, 300 yuan, 7,000 yuan or even nearly 100,000 yuan...

Blockchain training is too popular

I often Fabricated identities on dating profiles: imported lighting wholesaler, urban landscape designer, boutique cigarette hotel owner, agricultural loan salesman. Now, I have finally become an expert in blockchain training courses.

Moreover, it is reported that a blockchain recruitment advertisement in Beijing recently hit the circle of friends, asking applicants to check the area. Those with in-depth research on blockchain technology and cryptography will be offered an annual salary of no less than 5 million yuan.RMB, and there is no upper limit.

“This is indeed the current situation of blockchain talent recruitment. But even so, we can’t recruit people because it is difficult to find qualified people.” Lu Sheng, a “headhunter” on Liepin platform, said.

Song Mofei, a senior researcher at Suning Financial Research Institute, said: “In terms of development experience, the rise of the domestic blockchain industry has been concentrated in the past two or three years. People with long-term blockchain development experience are in the talent market. Very few." He believes that excessively high salaries will inevitably attract some speculators, but the increase in salary has not brought about an increase in the application threshold, and even some recruiters only have a vague understanding of blockchain technology. The recruitment of chain talents also poses new challenges.

In the view of Shan Yi, chief data officer of Liepin.com, the core of blockchain is a change in social relations and business models based on the Internet's distributed trust system, and this change is based on decentralization. are typical characteristics. "There are still many uncertainties in the future development of blockchain. There is an obvious bubble at present, and many blockchain projects are unreliable." He said.

F. Introduction to blockchain technology, what programming languages ​​are involved

Go language is the mainstream language of blockchain
According to the BOSS Research Institute data survey, currently in Recruiting blockchain positions
The mainstream languages ​​are Go and C++. Early blockchain systems and applications
Programs were mainly implemented in C++. Now most companies use Go language
Create a public chain system.
C++ is suitable for the development of local programs.
Go language is suitable for the development of network programs and local programs.
Advantages compared to C++Go:
Garbage collection
Clear semantics
Uniform format

Disadvantages:
Efficiency is currently not as high as C++ , but for desktop programs, efficiency is not a big problem because the hardware is already very fast.

C++ is currently the mainstream language and I believe it will become a classic like C.
The meaning of becoming a classic is that people who learn it can get a good salary, but it is only a good salary.
In the future network world, Go has a great chance of becoming popular, and I think its future is promising.

The developers of Go include the founder of Unix and the founder of C language. They are the first generation of hackers and I believe they will do a good job.

Now the go full-stack + blockchain market is experiencing an unprecedented boom, and the situation is gratifying.

G. Introduction to blockchain technology, which programming languages ​​are involved

Go language

Go language (Golang) is a brand-new programming language launched by Google in 2009 programming language that can be used without loss ofReduce code complexity without sacrificing application performance. Rob Pike, chief software engineer at Google, said: "We developed Go because the difficulty of software development over the past 10 years or so has been frustrating."

In addition to Bitcoin being developed in C, At present, the clients of most mainstream workshops are developed with Go language, which is enough to show the status of Go language in the entire blockchain industry.

C

C further expands and improves the C language and is an object-oriented programming language. C runs on a variety of platforms, such as Windows, MAC operating systems, and various versions of UNIX. C is a very widely used computer programming language. It is a general programming language that supports multiple programming patterns, such as procedural programming, data abstraction, object-oriented programming, generic programming, and design patterns.

Most blockchain companies choose to use C to write the bottom layer of the blockchain. The most famous ones are Bitcoin, Ripple, etc., which mainly reflect strong computation.

Java

Java is different from general compiled languages ​​or interpreted languages. It first compiles the source code into bytecode, and then relies on virtual machines on various platforms to interpret and execute the bytecode, thereby achieving the cross-platform feature of "write once, run anywhere". The development of blockchain projects has obvious dependence on Java.

Others include Python, system architecture, Ethereum, Linux, hyperledger, JavaScript, etc. will be covered.
