⑵ What are the basic concepts of blockchain programming and development technology

With the continuous development of the Internet, the development and application of blockchain technology has also been put on the agenda. Today java Course http://www.kmbdqn.cn/ Let’s learn about the basic concepts that need to be mastered in blockchain programming and development technology.

1. Blockchain technology

Chained data structure leaseback, the header of each block is saved Pointing to the hash value of the previous node, they are connected in sequence.

Based on the P2P network, the distributed node consensus algorithm maintains and updates data to ensure that the data is "non-tamperable".

Use cryptography principles to ensure the security of data transmission and access.

Automated scripts (smart contracts) to program and manipulate data.

Essentially it is a decentralized database, and what it ultimately wants to solve is the trust issue in Internet transmission.

2. Decentralization

The entire network is jointly participated and maintained by each node. Relying on central processing nodes, each node is the center.

Data storage and update are distributed and do not require intermediary or trust structure endorsement.

3. Private chain, public chain and alliance chain

Private chain:

Participating nodes have limited qualifications and controllability, and limited reading and writing.

Weak centralization solves the problem of trust among "teammates" (within the organization).

Public chain:

Open, anyone can read the data on the chain and participate in transactions.

Completely decentralized, the data on the chain cannot be tampered with by any person or institution.

Encourage participants to compete for accounting rights through a reward token mechanism.

Solve the problem of "human beings" (all people) being untrustworthy.

Consortium chain:

It is jointly participated, maintained and managed by multiple institutions. The data on the chain is only allowed within the system. Institutions read, write, and trade.

Partially decentralized, each institution runs one or more nodes.

Solve the problem of untrustworthy "organizations" (inter-agency) in Suisan.

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.

⑷ 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. insideThe 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.

⑸ How to learn blockchain technology_How to understand blockchain technology

1. Technical language

Python and Go are two languages ​​​​that are recruited by many companies All mentioned technical languages. Need to prioritize learning. Moreover, these two languages ​​​​also have great applications in the direction of sliding technology outside of the 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, BTC is written in C at the bottom level. 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.

Hyperledgerfabric is a blockchain development platform strongly promoted by IBM. It is mainly used for the development of alliance chains and 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.

(5) What do you need to learn for blockchain development? Further reading:

Blockchain technology is a distributed accounting technology, and its characteristics are as follows: Centralization, openness and transparency allow everyone to participate in the establishment of the database, and each created data cannot be tampered with. With everyone participating, 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, so here 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.
