1. Is it difficult to develop a public blockchain chain? How many domestic companies can do it?

Blockchain is a distributed data storage, point-to-point transmission, consensus mechanism, encryption New application models of computer technology such as algorithms. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each The data block contains information about a batch of Bitcoin network transactions and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

The biggest problem if such technology is to be put into application is the "impossible triangle problem"

That is, it cannot achieve scalability (Scalability) and decentralization (Decentralization) at the same time. ), security (Security), you can only get two of the three.

Most of the public chain projects currently on the market are difficult to put into use on a large scale.

2. Which is more difficult, cloud computing or blockchain development?

Blockchain is more difficult. The difficulty in developing the Yeqiao Blockchain Keychain is that it requires mastering a variety of technologies, including knowledge of cryptography, distributed systems, consensus algorithms, smart contracts, etc. Cloud computing development relies more on existing technology platforms and Serve. Both cloud computing and blockchain development require a high technical level and rich experience, but their difficulties and focuses are slightly different.

3. Is it difficult to learn blockchain?

I recommend an introductory book "Blockchain" written by Zhang Jian, and then you can read more information about blockchain , understand the current market with facts. If you want to speculate in currencies, you can first download a blockchain application store, which brings together all the necessary software for currency speculation on the market, including exchanges, wallets, information, community and other software, especially for those who want to speculate in currencies. It is especially convenient for beginner users. You can search online and call it BeeStore.

4. Is it difficult to learn blockchain now?

It is not difficult to learn. It depends on whether you are learning technology or investment knowledge. If it is technology, yes It may be easier to get started with some basic skills. If it is investment, it is easier to find a professional training institution to learn, and more importantly, there is a resource platform to achieve good results.

5. Getting started with blockchain technology, which programming languages ​​are involved

Go language

Go language (Golang) is a brand-new programming language launched by Google in 2009 A programming 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 all developed with Go language, which is enough to show that Go language hasThe status of the entire blockchain industry has changed.

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.

6. 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. It was first used as Virtual currency exists. 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, 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 greater 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 connect the EOS constitution to reach a consensus, 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 an array of 32 bytes. The private key can generate the public key and address, but this behavior is irreversible, so it is crucial to keep the private key. 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 promise in digital form. Both parties involved can execute these promised agreements on the consumer 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 by people around the world and can be read, 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.sail.

7. Is blockchain technology easy to learn? Can I learn it if I don’t have a high degree of education?

Blockchain technology is a very complex technology. Of course not too studious. Because if it is very good, it will not be so valuable if it is empty. But people with low academic qualifications can also learn, because learning like this also relies on talent.
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.
Characteristics of blockchain technology.
Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.
Openness. The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the data of the blockchain is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire System information is highly transparent.
Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without the need for any human intervention.
Security. As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.
Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be done anonymously
