① Introduction to blockchain technology, which programming languages ​​are involved

Theoretically, technology has no relationship with programming languages. Just like different languages ​​​​can express the same meaning, at the same time In theory, blockchain can be implemented in a variety of programming languages. If you want to learn blockchain technology, you can check out some technical information, technical manuals, etc. If you want to learn programming language, I suggest you read some programming language stuff. I hope it can help you.

② Getting started with blockchain technology, what programming languages ​​are involved

Go language is the mainstream language of blockchain
According to the BOSS Research Institute data survey, currently recruiting Blockchain jobs
The mainstream languages ​​​​are Go and C++. Early blockchain systems and applications
programs were mainly implemented in C++. Now most companies use Go language to
build 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.

③ Why do some people think that GO language will become a trend in developing underlying blockchains?

Why should we learn 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

④ How to learn blockchain technology

1. Technical language

Python and Go are two languages ​​​​that many companies are recruiting All mentioned technical languages. Need to prioritize learning. Moreover, the technical directions of these two languages ​​outside of blockchain are alsoThere are great applications. 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.

(4) What language is generally used to develop blockchain? Extended reading:

Blockchain technology is a kind of distributed accounting technology. Its characteristics are decentralization, openness and transparency, allowing everyone to participate in the establishment of the database, and each established data cannot be tampered with. Yes, everyone participates, and 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.

⑤ 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 ProtocolBuffers
can be directly compiled into machine code and does not rely on other libraries. The version of glibc has certain requirements. Deployment is completed by just throwing a file.
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.

⑥ Why do most blockchain projects not use Java for development

Blockchain projects have relatively high efficiency requirements, so most core source code development uses c/c++ . But if you are doing a blockchain project, unless you need to make a lot of adjustments to the source code, you may not choose to use Java. For general dapp applications, it should also be a good choice to use java to develop. For example, for the Ethereum blockchain, there is the web3j class library for Java, which is very convenient; for Bitcoin, there is the bitcoinj class library, which is also very easy to use. It still depends on what level of application it is, what it is going to do, and the situation of the team.

⑦ Go language can do it What

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 log processing, data packaging, virtual machine processing, file systems, 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. .

⑧ What is the relationship between blockchain and Java

What is blockchain? People are familiar with blockchainThe interest in blockchain is getting stronger and stronger, and people have also discovered that blockchain has an unusual relationship with Java. What is the relationship between blockchain and Java? Let’s discuss it with Huoying IT Training today.

1. What is blockchain?

Blockchain is the underlying technology of Bitcoin, like a database ledger. Record all transactions. This technology has gradually attracted the attention of the banking and financial industries because of its safety and convenience. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains the information of all Bitcoin network transactions in the past ten minutes, which is used to verify the validity of its information (anti-counterfeiting) and generate the next A block.

2. What is the relationship between blockchain and Java?

We know that Java is a high-end computer development programming language , Java has the characteristics of simplicity, object-oriented, distributed, robustness, security, platform independence and portability, multi-threading, dynamics, etc., so it is widely used by people. We can see that blockchain is a very important part of Bitcoin, and security requirements are particularly high, so Java is used to implement blockchain because of its unique characteristics.

We know that Java is the most widely used programming language in the world. From the perspective of Java application fields, it mainly manifests in three aspects: one is large and medium-sized commercial applications, and the other is desktop Applications (often referred to as c/s applications), and the third is applications in the mobile field. You haven't thought that Bitcoin, which is currently being speculated by everyone, is actually related to Java. It's no wonder that everyone prefers the Java programming language.

⑨ What is Solidity, the Ethereum smart contract development language?

Solidity language is a language specifically used for writing and executing smart contracts. It is a high-level contract-oriented language that runs on the Fang virtual machine. It was originally proposed by Gavin Wood, the former CTO and co-founder of Ethereum in August 2014. Later, a dedicated team was formed by Ethereum developers. , continuously improving the Solidity language, which is still under development and optimization. The development storage area on GitHub is https:/github.com/thereum/solidity, where we can learn the most comprehensive information about Solidity language development and Iterative process details and related documents. In terms of language style, Solidity language is deeply influenced by C++, Python and JavaScript. It is a statically typed programming language that is compiled in bytecode (Bytecode) mode, so it can be used in the Ethereum Virtual Machine. run on. GavinWhen developing the Solidity language, Wood drew on the grammatical rules of JavaScript's ECMAScript scripting language, making it somewhat similar to existing web development languages, but actually quite different. For example, the Solidity language has static types, variable return functions, etc. The most important point is that the Solidity language can write contracts with self-executing business logic and embedded in smart contracts. Therefore, it is not only one of the basic programming languages ​​​​of Ethereum, but also most other Ethereum-based smart contracts. The basic programming language of various blockchain products (Blockchain 2.0) of the contract is widely used in most current blockchain products. For example, the Hyperledger project was developed using the Soliditv language.
