『一』What is the blockchain and can it be invested in?

What is the blockchain and can it be invested in?

Blockchain technology is an emerging concept after the introduction of the Internet concept. It mainly solves the information asymmetry in society and provides decentralized services. Give an example to explain what blockchain technology is:

Usually we deposit cash into the bank. Every time we withdraw money, the transfer must go through the bank system to complete. So if we use blockchain technology To solve this problem, then our money does not need to be placed in the bank. When transferring money to others, we only need to transmit data on the chain. The transfer record data will be recorded by the entire network, and the consumption path of the amount can be found at any time. , there is no need to go through any intermediary to complete the intermediate recording.

This is just one of the scenarios where blockchain technology is applied. At present, the payment industry, gaming industry, lottery gambling industry, etc. are the most widely used blockchain technology.

In the nascent stage of the development of blockchain technology, many investors will naturally see the development potential and prepare to invest in blockchain. So how to invest in blockchain? Everyone knows that with the emergence of blockchain technology, digital currency will be generated, and the circulation of digital currency will generate value. Ordinary people can invest in blockchain by purchasing digital currency. Common digital currencies include Bitcoin, Ethereum, Yuzi, etc. However, the risk is extremely high. The return is much higher than that of stock investment, but the risk is also several times higher. Therefore, when investing in blockchain, the choice of digital currency is also very important. For novice investors, it is recommended to choose mainstream currencies, such as Bitcoin, Ethereum and Ripple. Their value has been basically recognized, they have a consensus mechanism, and the price will not drop significantly. However, the corresponding blockchain technology is still the best. Ethereum.

For professional risk control investors, you can choose to invest in blockchain companies, taking a fancy to their long-term value and tokens. Nowadays, blockchain companies will issue coins, which are so-called digital currencies. However, their value is zero and they have no actual circulation significance. Therefore, if you choose to invest in a blockchain company, you still need to see clearly the content of the company's projects, whether they can be truly implemented, and how much potential they have for changing human life in the future.

『二』What are the introductory books on blockchain?

"New Economic Blueprint and Introduction"

Published: 2016

Recommendation: This book is mainly for programmers. Combined with API programming, it tells you the principles and usage of cryptocurrency, and how to develop related software. For non-programmer readers, the first few chapters of this book are still applicable as an in-depth introduction to Bitcoin. (Book pdf download: https://quant.la/Download)

『三』 Blockchain Encyclopedia: The Past and Present of BlockchainLife - 3.0 era

The representative of the blockchain 1.0 era is Bitcoin, the representative of the 2.0 era is Ethereum, and the troubled times of various copycats and air coins. Blockchain 3.0 is the era of consumer-level blockchain that has truly entered commercial applications and physical applications after the troubled times. The typical symbol is the emergence of tokens. The pass has brought about changes in traditional business models and production relations. The pass has moved from the digital world to the real economy and has begun to seek practical applications in various industries.

The pass has three elements, one of which is indispensable.

Pass: The pass can be circulated on a large scale in a network and can be verified anytime and anywhere; Certificate: As a proof of digital rights and interests, the pass must be a certificate of rights and interests that exists in digital form, and it must represent It is a right, an inherent and intrinsic value; value: the token must have economic value.

In this way, the meaning of "token economy" is not difficult to understand. The token economy is a large-scale group collaboration based on tokens. It maximizes the role of tokens, allows every role that creates value to share value fairly, fully mobilizes participation motivation, and forms a self-organizing form.

Major changes in the blockchain 3.0 era

The token economy has laid the theoretical basis and technical support for the large-scale application of blockchain, and the future world will also be transformed by it. Large-scale changes include:

1. Fragmented investment, fragmented income, subverting the traditional way of doing business on the Internet. In the traditional Internet era, it was impossible for ordinary people to participate in the investment of a company, but the emergence of blockchain allows ordinary people to make fragmented investments in a large asset. Assuming that Alibaba originally adopted blockchain for fragmented investment, then all fragmented shareholders who invested in Alibaba would be able to reap a return on investment that has increased thousands of times today!

2. Break the money-burning model of the Internet and make everyone a winner. The free model of the traditional Internet is essentially to obtain a large number of users through free products to form monopolies and barriers, and then make profits through advertising and value-added services on this basis. In the blockchain 3.0 era, project income is redistributed by issuing tokens to attract more early investors and community users. As the number of users holding tokens increases, the value of the tokens will become higher and higher, and community users, investors, and projects can all benefit from it. In this way, the money-burning model of providing free services in the early days of the traditional Internet can also be improved, and everyone will become a winner.

3. Breaking down the traditional corporate organizational hierarchy, self-organization may become a future trend. In the blockchain 3.0 era, through the establishment of distribution and collaboration mechanisms through smart contracts, it can be more efficient and accurate than enterprises. All token owners will naturally form a community, and everyoneThey are all for the same goal - "promote the development of the project and make it a success". They are all members of the community, contribute to the community, promote the value-added of the token, and thereby make profits together. From a philosophical perspective, this new self-organizing community of freedom, independence, and equality must be the future trend. Gojoy blockchain e-commerce is a blockchain self-organized community. Every consumer is a token owner and a fragmented investor, so he is very happy to co-create and build Gojoy value.

Therefore, we can look forward to the era of great development of the blockchain 3.0 token economy, and the existing ones may be subverted. What we need to be prepared for is to work hard to embrace the blockchain. If you want to seize the trend of blockchain and understand how to transform into blockchain, please leave a message to communicate and we will take you to learn the blockchain professional certification course.

『四』What are the basic knowledge about blockchain

1. Application of blockchain technology in banking industry

Blockchain technology is the largest The characteristic of is decentralization, and this feature will reduce a lot of costs for the banking industry. The development of digital currency will make it possible to realize real-time digital transactions in banks. For example, in bill transactions, bank bill transactions have always relied on a third party to realize the transfer of valuable certificates. Even electronic bill transactions require interactive authentication through information from the central bank's ECDS system. . Blockchain technology can realize point-to-point transfer of value and no longer requires centralized system control. This not only speeds up the speed of ticket transfer, but more importantly, it can reduce errors caused by human factors and reduce processes. Naturally, it will reduce the bank's demand for personnel and save the bank's labor costs.

2. Application of blockchain technology in the insurance industry

Blockchain technology also has incomparable advantages in the insurance industry. From the perspective of data management, the application of blockchain technology by insurance companies can effectively improve risk management and control capabilities, including the risk supervision of insurance companies and the risk management of policyholders.

The application of blockchain technology in the insurance industry can strengthen the internal risk supervision of insurance companies. Blockchain technology can record the daily operating processes of insurance companies on nodes, and can achieve in-process control over the company's capital flow, investment status, compensation payments and other businesses, and improve the company's risk management and control capabilities.

3. Application of blockchain technology in the securities industry

The application of blockchain technology in the securities industry can increase the flexibility of securities issuance. Companies issuing securities can use smart contracts , by setting the method and time of securities issuance, securities can even be issued 24 hours a day under the most ideal condition.

4. Blockchain technology and financial infrastructure

Blockchain technology uses a decentralized mechanism to exchange value, which will lead to a modern world characterized by centralization. Some financial infrastructures have undergone earth-shaking changes.

5. Application of blockchain technology in supply chain

The application of blockchain technology in the supply chain first provides credit protection. The blockchain records the circulation information of commodities, etc., which can prove the true reliability of commodities and their circulation, thus enabling A comprehensive evaluation of the utility of enterprises on the chain has become an effective guarantee for corporate bank loan credit, financing credit, and transaction credit.

『五』What is blockchain: This explanation of blockchain is more understandable

Blockchain is an important concept of Bitcoin. It is essentially a disintermediation The database, as the underlying technology of Bitcoin, is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of its information ( Anti-counterfeiting) and generate the next block.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. Fake distributed ledger.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

(5) Tokenbook Blockchain Popular Science Extension Reading:

The evolution method of blockchain is:

▪ District Blockchain 1.0 - digital currency;

▪ Blockchain 2.0 - digital assets and smart contracts;

▪ Blockchain 3.0 - the implementation of distributed applications in various industries.

Blockchain characteristics:

1. Disintermediation. Due to the use of distributed computing and storage, there is no centralized hardware or management organization in the system. The rights and obligations of any node are equal. The data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.

2. Openness. The system is open. In addition to the encryption of private information of all parties to the transaction, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the entire system information is highly transparent. .

3. Autonomy. The blockchain adopts consensus-based norms and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment, changing trust in "people" to trust in "people". Machine trust, any human intervention has no effect.

4. Information cannot be tampered with. Once information is verified and added to the blockchain, it is stored permanentlyGenerally speaking, unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node will be invalid. Therefore, the data stability and reliability of the blockchain are extremely high.

5.Anonymity. Since the exchange between nodes follows a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to disclose its identity to make the other party trust itself. Very helpful for credit accumulation.

『Lu』What does blockchain mean and how to understand it

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. .

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of related data generated using cryptography methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

Notes

1. Blockchain Originated from Bitcoin, on November 1, 2008, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, The architectural concepts of electronic cash systems such as timestamp technology and blockchain technology mark the birth of Bitcoin.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations have been striving for, Puyin Group launched the On the 9th, a Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou. At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the application of blockchain services and social public industries will be discussed. Explore.

『撒』 What does "blockchain" mean briefly and concisely?

Answer: 1. The connotation of blockchain

Blockchain is distribution New application models of computer technologies such as automatic data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms.

2. Characteristics

1. 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, through distributed accounting and storage, each node realizes information self- Validate, deliver and manage.

2. Openness.

The foundation of blockchain technology is open source. In addition to the private information of the parties to the transaction being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data through the public interface. and develop related applications, so the entire system information is highly transparent.

3. Independence.

Based on consensus specifications and protocols, 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 any human intervention.

4. Security.

As long as you cannot control 51% of all data nodes, you cannot arbitrarily manipulate and modify network data. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity.

Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be done anonymously.

『8』 The magical blockchain allows data to be retained permanently

At the beginning of this year, the Bitcoin fever wave had not completely passed, and another wave of " "The torrent" could not stop the fire. This is the blockchain technology that has been hotly speculated in the financial and insurance fields recently, and has even made a strong presence in the stock trading and voting industries.

When talking about the recent hot spots in various industries, this technology must be one of them. Data to illustrate: So far, the world’s largest investment projects in 2016 are all related to blockchain, with investment amounts reaching US$55 million and US$60 million respectively. The largest blockchain project in China was also announced at the end of September this year. Also announced with an investment scale of over US$20 million.

First of all, normatively speaking, this is a new application model that comprehensively uses computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. As we all know, Bitcoin, as a global encrypted Internet currency, was developed based on blockchain technology. The support of smart contracts on the blockchain has made a wider range of point-to-point transfers of digital assets other than Bitcoin a reality. It is not difficult to understand why blockchain technology has become compelling as the cornerstone of the Internet of Value.

So why is blockchain so attractive? If today’s Internet is the point-to-point transmission of information through the TCP/IP protocol, it is the information Internet, then the point-to-point transfer of value (such as electronic currency, electronic assets, etc.) without a third party is made possible by blockchain technology.

In layman’s terms, blockchain is a decentralized distributed accounting system. Nodes in the system do not need to trust each other. They jointly maintain a ledger through a unified consensus mechanism, and each node has a complete data record. Blockchain Blockchain, blocks of transactions are connected together through cryptographic algorithms, making the entire ledgerOpen, transparent, traceable, and non-tamperable.

Compared with traditional third-party institution credit transactions, the process of blockchain in digital payment can be described as the following diagram:
