总之，要成为一名优秀的区块链程序员，需要学习计算机科学、编程语言和区块链技术相关的知识。只有掌握了这些知识，才能更好地利用区块链技术，为企业和社会做出更大的贡献。

A. How to get started with blockchain. This knowledge is not difficult to learn.

1. To learn blockchain knowledge, first learn the necessary concepts of blockchain knowledge.

2. [Blockchain]

The English name blockchain is the underlying technology of Bitcoin and a decentralized accounting method.

3. [Block and Chain]

Block refers to the information block that records transaction information. Each block contains three main factors: The ID of the block, the odd number of the transaction, and the ID of the previous block.

The Bitcoin system generates a block approximately every 10 minutes. Each block contains the ID of the previous block, making the blocks form a complete transaction chain. The longest one is The only master blockchain.

4. [Bitcoin]

Bitcoin is a practical application of blockchain technology. It is a peer-to-peer electronic cash payment system that first existed as a virtual currency. , Japan has recognized the legality of Bitcoin and can use Bitcoin for shopping.

5. [Satoshi Nakamoto]

The legendary founder of Bitcoin published a paper on a peer-to-peer electronic cash system in 2008, marking the The birth of Bitcoin.

6. [Digital Currency]

It is completely different from the Q coins and other virtual currencies we use to play games in real life. For example, in Japan, although Bitcoin is a digital currency , but it can already be used to purchase goods in real scenarios.

7. [PoW]

A type of consensus mechanism, also known as proof of work. Bitcoin currently uses this consensus mechanism. It is relatively simple and easy to reach consensus, but consumes huge amounts of energy and is prone to bifurcation.

8. [PoS]

A type of consensus mechanism, also known as proof of equity. People with greater equity have a higher probability of becoming bookkeepers, but bookkeeping Human ones are not necessarily professional, don’t consume much energy, and are prone to split ends.

9. [DpoS]

On the basis of PoS, the bookkeepers are changed from unprofessional to professionals, like the EOS we are familiar with. In this consensus method, holders jointly select 21 nodes and 100 reserve nodes to reach consensus on the EOS constitution, and jointly incubate the ecology on EOS.

10. [Public key and private key]

In the world of blockchain, the public key is equivalent to the bank account number, and the private key is equivalent to the bank account number + withdrawal password. The private key is essentially composed of 32An array composed of bytes, the public key and address can be generated from the private key, but this behavior is irreversible, so it is crucial to keep the private key well. Losing the private key is equivalent to losing money, and it can never be found back.

11. [Hash value]

It can be simply thought of as a set of data that is closely arranged together. No item in the data can be changed, otherwise The calculated consequences will be very different.

12. [Smart Contract]

It is a commitment in digital form. Both parties involved can execute these commitments on the network without artificial restrictions.

13. [Credit Consensus]

Based on the characteristics of blockchain, it is a distributed accounting method that cannot be tampered with and is irreversible. A mechanism of trust that allows many people to form a trust based on digital algorithms.

14. [Public chain and private chain]

Public chain refers to a blockchain that can be participated in and read by people all over the world, and is open to everyone , while the private chain is only in the hands of an organization and is only open to individuals or entities.

Blockchain is currently a hot topic. Many traditional large enterprises and venture capital are actively participating in the layout and investment of the blockchain industry. As the general public, we must master the necessary blockchain knowledge. , helps us judge and analyze real-world information and protect our investments.

B. What to study in the blockchain technology application major?

The blockchain technology application major should study the financial field, insurance field, Internet of Things and logistics field, digital version field, and public service field. . It can be seen that the development prospects and employment fields of the blockchain engineering major are relatively broad.

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.

Blockchain technology:

This major cultivates the comprehensive development of moral, intellectual, physical, artistic and labor skills, and masters the basic knowledge of natural sciences, humanities and social sciences, and the basics of computer science Theory, basic theory and application knowledge of blockchain technology and application, competition and team awareness and craftsman spirit, high-quality and high-level technical skills talents who can engage in blockchain technology design, management, service and other work.

Blockchain is closely related to people’s production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

C. What technology development is needed for blockchain

What technology development is needed for blockchain:
1. Blockchain theory: Blockchain developers must understand the differences between Being familiar with the theoretical knowledge of blockchain is the most basic requirement 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.

D. What courses do you need to learn about blockchain?

The courses you need to learn about blockchain include: 1. Khan Academy; 2. Udemy; 3. Lynda; 4. Coursera; 5 .PluralSight etc. In addition, to learn blockchain, you must also know the relationship between blockchain and programming languages. It is recommended to learn blockchain development based on Go language and Java, and Go language is slightly less difficult to learn than Java.
