⑴ Getting started with blockchain technology, what programming languages ​​are involved

Go language is the mainstream language for blockchain
According to BOSS Research Institute data survey, currently Blockchain positions currently being recruited
The mainstream languages ​​​​are Go and C++. Early blockchain systems and applications
Programs were mainly implemented in C++. Now most companies use Go language
Build 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.

⑶ Introduction to blockchain technology, which programming languages ​​are involved

Go language

Go language (Golang) is Google’s 2009 Introducing a new programming language that reduces 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.

Some experts said that in the future, blockchain will be closely related to people's lives, and the integration of blockchain technology into people's daily lives is the general trend.

The popularity of the blockchain market has triggered a large demand for talents based on blockchain technical personnel, and the popularity of blockchain talents is rising at light speed. According to the "2018 Blockchain High Salary List" released by Lagou.com, domestic corporate giants such as Tencent, Xiaomi, Suning, and JD.com have released numerous high-paying blockchain job requirements in an effort to explore blockchain-related technologies and applications. The list also points out that high-paying positions are mainly in demand for blockchain-related technical positions, among which Suning and Keda have given the highest monthly salary of 100k.

The huge market demand for technical talents will inevitably drive the explosive emergence and growth of the entire blockchain training market. Most training models can be divided into online training, traditional IT institution training and high-end offline short-term training camps. However, the market is also full of various blockchain training chaos during the hot evolution: the instructor qualifications are watered down. , Even the most basic names are not disclosed, the course syllabus is opaque, the teaching quality has shrunk, the class schedule is unreasonable, and the training fee standards are uneven, etc.

⑻ What technology development is needed for blockchain

What technology development is needed for blockchain:
1. Blockchain theory: Blockchain developers must understand the blockchain Theoretical knowledge and familiarity with it are the most basic requirements for a blockchain developer. The content includes blockchain network architecture, decentralization and other related application technologies. Expanding technical theory is mastery of Ethereum development.
2. Smart contract: Smart contract is a string of codes that blockchain developers need to write in blockchain programming language. It is a trust mechanism developed after imagining logic according to different scenarios, aiming to eliminate the intervention of third parties. Create an efficient and high-trust blockchain network. Blockchain developers need to realize automatic execution of this string of code, and the operation effect is irreversible.
3. Cryptography: Many blockchain application scenarios have high encryption, and point-to-point encryption mode is a characteristic of cryptography. By studying cryptography, blockchain developers understand encryption concepts such as wallets, keys, and a wide range of encryption and decryption technologies
4. Distributed architecture: Blockchain developers must understand the functions of distributed architecture and networks . Decentralized network is the foundation of the blockchain architecture. The transmission of information in the blockchain network must follow a decentralized approach so that everyone can enjoy the same network rights.
