Ⅰ If you want to get started quickly with blockchain technology, what programming languages ​​are generally involved?

Any computer language can achieve different applications in a specific field. Blockchain technology;

Which language to use depends entirely on the technical requirements of our enterprise projects in the corresponding fields, and more importantly: effective connection with existing information systems.

The "Fada" that we are familiar with (although the name is not very nice, and even sounds a bit confusing at first), it is actually preparing to adopt the latest The blockchain technology is restructured; the contract platform using blockchain technology becomes more trustworthy and makes it easier for people to sign various business contracts in the Internet era.

There are also "credit reporting systems" like ours, which are also very suitable for transformation with blockchain technology. This can make it more convincing and avoid the situation where a unit or even any key technical personnel can add "credit tainted data" to it at will.

There are also P2P loans like ours, if they can be restructured with blockchain technology, they can also become more trustworthy and avoid such breaches of trust as defaults and running away with money.

II 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, the blockchain positions currently being recruited
The mainstream languages ​​​​are Go and C++. Early blockchain systems and applications
The programs are mainly implemented in C++. Now most Companies will use Go language to
build public chain systems.
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.

Ⅲ 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 Language that can reduce the complexity of code 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.

IV If I want to get started with blockchain technology, which programming languages ​​should I learn

Go language + blockchain training course:
Why should I learn GO language, GO’s What are the advantages?
1. What are the advantages of Go
Advantages of Go
1: Performance
2: Language performance is very important
3: Developer efficiency & don’t be too innovative
>4: Concurrency & Channels
5: Fast compile time
6: The ability to build a team
7: Strong ecosystem
8: GOFMT, mandatory code format
/>9: gRPC and Protocol Buffers
can be compiled directlyinto machine code and does not depend on other libraries. The version of glibc has certain requirements. Deployment is completed by just throwing a file in it.
A statically typed language, but with the feeling of a dynamic language. A statically typed language can detect most hidden problems during compilation. The feeling of a dynamic language is that there are many packages that can be used, and it is very efficient to write. high.

Ⅳ How to learn blockchain technology

Recently there has been an endless stream of news about various digital currencies. Bitcoin is the one that everyone is most familiar with. It was speculated by Hu Ce a long time ago. There was an uproar. There are many people who make a lot of money from this. Of course, different countries have different recognitions of Bitcoin, but no matter what the future trend of Bitcoin is. Knowledgeable people should see more than just digital currencies such as Bitcoin, because these are temporary hot spots after all, and it is still a matter of speculation as to which currency will make it to the end.
Bitcoin is just an application product brought about by new technological innovation, and what really changes future technology is not the digital currency, but the blockchain technology behind it. Recently, whenever blockchain technology is mentioned, it will become a hot topic. However, as everyone knows, some well-known Internet companies such as Internet, Tencent, Xiaomi, and Xunlei have been unconsciously conducting research in the field of blockchain for a long time.
While ordinary netizens are still obsessed with hyping various virtual currencies, smart people have already begun research and study on blockchain technology. Of course, since it is a new technology, not many people know how to show it, and even fewer people study it in depth. But in any case, blockchain technology has deeply entered the research scope of various large companies. As more powerful companies invest in research in this area, the demand for blockchain technology talents will increase.
Things are rare and valuable, but the same is true for people. When the market demand for blockchain technology becomes greater and greater, and even when new product applications created by blockchain technology appear in the future, the demand for blockchain talents in the entire Internet community will far exceed that of iOS back then. The scene in heat. Of course, for those who understand blockchain technology, the objective salary will also become the envy of other technical professionals.
Go language is the second open source programming language released by Google in 2009.
The Go language is specially optimized for programming multi-processor system applications. Programs compiled using Go can be as fast as C or C++ code, are more secure, and support parallel processes. Not only can you develop the web, but you can also develop the underlying layer. Currently, Zhihu is developed using golang. The preferred language for blockchain is go, Ethereum, and Hyperledger are all based on go language, as well as the go language version of btcd.
The goal of Go is to improve the dependency of existing programming languages ​​on libraries and other programs. Management, these software elements will be called repeatedly by the application. This language is also designed to solve multi-processor tasks due to the existence of parallel programming models.
Google vs.Go has high hopes. Its design is to allow the software to take full advantage of the simultaneous multitasking of multi-core processors and to solve the troubles of object-oriented programming. It has modern programming language features, such as garbage collection, to help programmers deal with trivial but important memory management issues. Go is also very fast, almost as fast as C or C++ programs, and can quickly create programs.
Go's website was built using Go, but Google has greater ambitions. The software is specifically designed for building server software (such as Google's Gmail). Google believes that Go can also be applied to other areas, including executing software within the browser and replacing the role of JavaScript.

VI What can be done with go language

1. Server programming: If you used C or C++ to do those things in the past, Go is very suitable for doing them, such as processing logs and data packaging. , virtual machine processing, file system, etc.

2. Distributed systems, database agents, middleware: such as Etcd.

3. Network programming: This area is currently the most widely used, including Web applications, API applications, download applications, and Go’s built-in net/http package basically implements all the network functions we usually use. .

4. Development of cloud platforms: Currently, many foreign cloud platforms are developed using Go. The well-known Qiniu Cloud, Huawei Cloud, etc. have products developed using Go and are open source.

5. Blockchain: There is currently a saying that technical practitioners call Go language the development language of the blockchain industry. If you study blockchain technology, you will find that many blockchain systems and applications are developed using Go. For example, ehtereum is currently the most well-known public chain, and fabric is currently the most well-known. Alliance chains, both have go language versions, and go-ehtereum is also the officially recommended version of Ethereum.

Many later projects were re-implemented natively using the Go language. This process was simpler than other languages, which also contributed to the emergence of a large number of native development projects using the Go language. .

Ⅶ How to systematically learn blockchain technology

When you first learn blockchain-related knowledge by yourself, you can use the "bottom-up" method, or That is, by reading books, white papers, etc., you can check the information yourself, and then summarize and connect this knowledge yourself, integrating it into a relatively complete knowledge system.

1. Study White Paper

Before going to college, I read many books about "The Analects", all about how to read the Analects and how to understand the interpretation of the Analects. Until one day I discovered that I, who loved "The Analects of Confucius" so much, had never had the patience to read the original version of "The Analects of Confucius" seriously.

So, I went to the bookstore to buy itI bought a copy of "The Analects of Confucius" and read it carefully from beginning to end. I found that there are actually too many details and insights in it that cannot be conveyed through any interpretation. But I actually spent a lot of time and read a lot of interpretations before. I was really trying to ignore the essentials and focus on the essentials.

It’s the same in every field. When you don't understand it, you will have an inexplicable fear of it, thinking that it is high and unattainable. In order to quickly enter these fields, you will look for many so-called "interpretations" and inquire about many "news" around them.

2. Technical perspective

Basic stage:

1. "Blockchain Development Guide" - Author Shentu Qingchun:

Author The research on the underlying layers of redundant Bitcoin can be said to be very in-depth, and the explanations are also very easy to understand.

2. "Blockchain Technology Guide" - Author Zou Jun:

As the first domestic book to explain blockchain from a technical perspective, it is worth reading. It was published in 2016 The reviews have always been good.

3. "Blockchain Principles, Design and Applications" - Author Yang Baohua and Chen Chang:

Senior Chen Chang, as the CTO of Zhigui, remembers that the previous MoChain was based on Hyperledger Fabric , so this book provides a thorough explanation of Hyperledger-related open source products.

3. "Blockchain World"

This book is divided into two parts. The previous article comprehensively reviewed the birth, growth and gradual development of blockchain from 2008 through detailed information, and introduced in detail the originality of blockchain technology, the scientific nature of the mechanism, and the artistry of logic. Through finance, More than ten industry scenarios including anti-counterfeiting and medical care introduce the application characteristics of blockchain. The next article combines the spirit of the G20 Summit and the latest policies such as the “13th Five-Year Plan” to explore the combination of blockchain and digital economy, as well as the author’s views and suggestions on industry development trends.

Ⅷ What do we need to know to learn blockchain

First we need to understand the relevant content of network communication, followed by data storage, encryption technology, consensus mechanism and security technology, and finally cross- On-chain technology and off-chain technology. I personally think that learning about blockchain should start from practice. If you are a programmer, you can go to a blockchain-related company to get in touch with related businesses and learn on the job. I used to work at Xuanling Technology, and the company’s strength and experience in blockchain development are very good, making it a good candidate for both work and cooperation.

Ⅸ How to learn blockchain technology

1. Technical language

Python and Go are the two technical languages ​​​​mentioned by many companies in recruitment. Need to prioritize learning. Moreover, these two languages ​​​​also have great applications in technical directions other than blockchain. For example, Go is used in the background construction of large-scale concurrent systems, and Python is used in the construction of artificial intelligence systems. So learning these two languages ​​is a priority.

2. Technical framework

Master one or more of Bitcoin, ETH and Hyperledger. Needless to say about BTC, the bottom layer is written in C++. A large number of currency projects, such as Litecoin, Dash, Monero, zcash, etc., all use Bitcoin technology for secondary development.

ETH is the representative of blockchain 2.0, and various application Dapps can be built on the ETH network. Nowadays, a large number of application blockchain projects are developed using the ETH platform.

Hyperledger fabric is a blockchain development platform promoted by IBM. It is mainly used for the development of alliance chains. It is currently the most popular alliance chain development platform.

3. Algorithm

POW (Proof of Work Algorithm), POS (Proof of Stake Algorithm), PBFT (Byzantine Fault Tolerance Algorithm), etc. are all important in the cryptography part of the blockchain Composition, a full understanding of these algorithms will help you have a better understanding of the cryptography part when participating in the underlying development of blockchain projects.

(9) Blockchain First Language Expansion Reading:

Blockchain technology is a distributed accounting technology. Its characteristics are decentralization, openness and transparency, allowing everyone to participate in the establishment of the database, and each created data cannot be tampered with. With everyone involved, the problem of trust between strangers is solved.

Blockchain technology has emerged. It is an accounting technology that allows all people to participate. The transaction information and data between AB are published to the public and cannot be tampered with. Everyone knows that this has happened. Then there is no need for an authoritative third-party C, or everyone in the system plays the role of C. This is also called decentralization.

Ⅹ What is blockchain? What do you study in blockchain engineering?

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
