㈠ What is the so-called "blockchain"

It can be said that 2020 is the first year of industrial blockchain. With the continuous development of blockchain technology, the number of companies actively deploying blockchain has grown exponentially. However, blockchain is still in a very early stage of development, and the implementation of blockchain applications still requires continuous exploration.
In the past ten years or so, blockchain technology has had a wide impact on a global scale. Compared with its inception, the face of the blockchain industry has undergone earth-shaking changes.
The blockchain market in the past few years was more like the Internet before 2000. The Internet before 2000 went through a period of restlessness and experienced ups and downs. Then the big waves washed away the sand, and truly powerful companies developed. .
While participating in the Cointelegraph Chinese event, Avalanche Asia Ecology Partner Wilson said: "In 2018, the blockchain ecosystem was completely different from now. At that time, it was more conceptual. Starting last year, the district The blockchain industry has undergone great differences. More and more reliable projects have been born.”
Indeed, in addition to being initially limited to applications in the field of digital currency, blockchain technology has now gradually become the basis of different traditional industries. facility. After more than ten years of exploration and research and development, blockchain has also discovered more application scenarios that highlight its value.
The growth momentum continues, but large-scale application has not yet been achieved
It can be said that 2020 is the first year of industrial blockchain. With the continuous development of blockchain technology, the number of companies actively deploying blockchain has grown exponentially. Against the backdrop of the COVID-19 outbreak, blockchain technology has also shown its huge untapped potential.
In the past year, global blockchain companies have continued to grow, but at a slower pace. According to data from the China Academy of Information and Communications Technology's "Blockchain White Paper (2020)", as of September 2020, there are 3,709 blockchain companies in the world, mainly distributed in the United States and China, of which the United States accounts for 27%. China accounts for 24%.
Obviously, as countries around the world continue to introduce positive blockchain policies and promote blockchain technology to empower the real economy, the blockchain industry bubbles are gone and the industry has returned to rationality. More and more companies are entering the market and actively using blockchain technology to expand their business.
Even though blockchain-related companies are springing up like mushrooms after a rain, blockchain is still in a very early stage of development. From the bottom of the protocol layer, it is still very early to be mature and complete. The middleware layer may be very far away from maturity, and the middleware layer may be a very important infrastructure required for the future integration of blockchain with the real world and real economy.
When these things have gradually become standardized and mature, we will usher in a stage where blockchain will become mainstream and explode.
For the development status of the entire blockchain technology, Helium China ManaGing Director Gao Yuan pointed out: "The current user experience of various blockchain applications is not very good. The development of middleware and the maturity of the user end are the key points to achieve large-scale applications. In the end, blockchain can be implemented and become a real economy. Part of it requires maturity and clarity at the regulatory level."
However, the implementation of blockchain applications still requires continuous exploration. If the performance of the underlying infrastructure of the blockchain is not improved, it will be difficult to achieve large-scale commercial applications in the future. So, what is the reason why a large number of blockchain applications have not been successfully implemented? Charlie Hu, head of Polygon China, believes:
First, it is not friendly enough to developers;
Second, it has limited expansion capabilities;
Third, it lacks interoperability, and its core logic is the future blockchain The world is not just one chain, but multiple chains coexist. Based on the existence of different chains for different commercial applications, cross-chain interoperability is very important.
Why is interoperability crucial for different blockchains?
The "interoperability" of blockchain means that different blockchain networks can easily communicate with each other and share information. Interoperability mainly refers to application layer interoperability, inter-chain interoperability, and off-chain data interoperability.
IOHK CEO and Cardano founder Charles Hoskinson said in an interview with Forbes that blockchain interoperability will lead to easy migration from one system to another.
In the blockchain industry, a blockchain that can meet user needs and operate efficiently is a necessity, and its status is very important. Although Ethereum has innovatively created smart contract technology and built a super ecosystem containing various applications, it is far from meeting commercial needs, at least until Ethereum 2.0 is fully launched.
Why is blockchain interoperability so important? With the continuous expansion of blockchain technology itself and the expansion of its applications in different industries, it is difficult to interoperate between different chains, difficult to connect between different applications, and difficult to trust the interaction between the chain and the off-chain. These problems are very important. To a certain extent, it limits the large-scale application of blockchain.
The scenario requirements between different blockchains may be different, and under these different requirements, a large number of interactions are required. Regarding interoperability, Iris, head of Asia business strategy at Edge & Node, said: "If there are islands between chains, there will be no way to interact, which will greatly affect applications. Interoperability across chains has different levels. From assets to data, to a lower-level consensus. Many projects have already realized asset cross-chain, and the next more difficult step is data cross-chain.”
It is far from achieving interoperability between different blockchains. not enough. According to Zhixian, the founder of Leitu Technology, interoperability should not be limited to the blockchain ecosystem. Only by opening up the interoperability between the blockchain and the Internet can the user base be maximized.
Cross-chain technologyTechnology is key to achieving interoperability. Currently, cross-chain technologies include notary mechanisms, side chains/relay chains, hash time locking, and distributed private key control.
In terms of data trust and security issues during the interaction process, O3Labs product VP Tim believes that the interoperability of different chains may have some challenges. He added:
First, user experience. Products must be made for more users. Whether in enterprises, institutions or consumers, user experience issues will be taken into consideration. Even if it can be achieved in terms of technology, it must also be achieved in terms of experience.
Second, security. Different chains will need to adjust some off-chain data. Different chains have different methods, so it is important to ensure the accuracy of the data. Because this will become a foundation, if there are many applications on this chain in the future, the accuracy and speed of these data must be very consistent.
Just like the emphasis on privacy protection in the traditional Internet, privacy protection issues must also be paid attention to between different chains and in the process of on-chain and off-chain interactions. Every interaction should avoid privacy leakage during the interaction. Suterusu CTO Lin Huang said that currently, there are too many cross-chain projects, and there are many products in this area. However, there are relatively few products that consider supporting multi-chain privacy protection. Suterusu has already done a lot of work on privacy protection and will be deployed on some chains next.
The future of blockchain - the coexistence of multiple chains
The blockchain industry has been constantly evolving. In addition to Ethereum, there are many blockchains emerging with the same vision as Ethereum, such as EOS, Polkadot, Cosmos, Avalanche, Polygon, etc.
Competition and cooperation are inevitable for the development of various industries, and the same is true for the blockchain industry. Only through competition can we continue to innovate.
In the future, Ethereum will not be "one super, many strong", but will inevitably form a situation where multiple chains coexist. Different public chains and different infrastructures will have some differentiated competition, and finally these different chains will be connected through cross-chain technology.
When asked about the future development of blockchain, He Yifan, executive director of the BSN Development Alliance and CEO of Beijing Hongzao Technology Co., Ltd., looked forward to:
In 3 to 5 years, especially the operating system layer will become more and more mature. In this case, blockchain technology should become a conventional technology. If developers don't even know how to use traditional databases, they don't have to work at all. In 3 to 5 years, every developer should be able to use blockchain technology to build basic applications.

㈡ Comic illustration: What is blockchain

Comic illustration: What is blockchain

What is blockchain?
Blockchain, English Blockchain, is essentially a decentralized distributed database. Anyone can become a part of this huge network as long as they set up their own server and access the blockchain network.nodes.
Since the blockchain is essentially a database, what exactly is stored in it? Let’s take a look at the basic unit of blockchain: Block.
A block is divided into two parts:
1. Block header
The block header stores the header information of the block, including the hash value (PreHash) of the previous block. The hash value of the block body (Hash), the timestamp (TimeStamp), etc.
2. Block body
The block body stores the detailed data (Data) of this block. This data contains several rows of records, which can be transaction information or some other information.
What does the hash value just mentioned mean?
Everyone must have heard of MD5. MD5 is a typical hash algorithm that can convert a string of plaintext of any length into a string of fixed length (128 bits). This string is the hash value.
In our blockchain, a more complex hash algorithm called SHA256 is used. After a series of complex calculations, the latest data information (such as transaction records) will eventually be converted into a 256-bit hash value string through this hash algorithm, which is the Hash in the block header. The format is as follows:

Blocks and Hash have a one-to-one correspondence, and Hash can be regarded as the unique identifier of the block.
How are different blocks related to each other? Rely on Hash and PreHash to associate. The PreHash value of each block is equal to the Hash value of the previous block.
Why do we need to calculate the hash value of the block?
Since the blockchain is a chain structure, there must be a head node (the first block) and a tail node (the last block) of the chain. Once someone calculates the hash value of the latest data in the blockchain, which is equivalent to packaging the latest transaction records, a new block will be created and connected to the end of the blockchain.
The Hash of the new block header is the hash value just calculated, and the PreHash is equal to the Hash of the previous block. The data in the block body stores the transaction records before packaging, and this part of the data information has become unmodifiable.
This process of calculating Hash values ​​and creating new blocks is called mining.
The server used for massive calculations is called a mining machine.
The workers who operate calculations are called miners.
What is so difficult about calculating hash values? Let’s give the most superficial explanation. The formula for calculating the hash value is as follows:
Hash = SHA-256 (Hash of the last block + basic information of the new block + transaction record information + random number)
Among them, the transaction record information is also a string of hash values, and its calculation involves a data structure Merkle Tree. Interested friends can check the relevant information, we will not introduce it for now.
The key computational difficulty here lies in the generation of random numbers. In order to increase the difficulty of Hash calculation, the wretched inventor of the blockchain requires that the first 72 bits of the Hash result must be 0. This probability is too small.
Since (the Hash of the last block + the basic information of the new block + the transaction record information) is fixed, whether the Hash that meets the requirements can be obtained depends entirely on the value of the random number. Miners must go through massive calculations and repeatedly generate random numbers in a general attempt to "get lucky" before they can get the correct Hash and successfully mine.
At the same time, the block header also contains a dynamic difficulty coefficient. When the world's hardware computing power becomes faster and faster, the difficulty coefficient of the blockchain will also increase, making the entire network capable of completing the task every 10 minutes on average. A new block is generated.
Friends, do you understand how difficult mining is? It should be added that different blockchain applications are different in details. The mining rules described here take Bitcoin as an example.
Applications of Blockchain

The concept of Bitcoin (BitCoin) was first proposed by Satoshi Nakamoto in 2008, and then based on this idea, open source software and P2P built on it were designed and released. network. Bitcoin is a P2P form of digital currency. Peer-to-peer transmission means a decentralized payment system.
What is a P2P network?
Traditional currencies are uniformly issued by the central bank, and all personal savings are uniformly managed by banks. This is a typical centralized system.
Bitcoin is deployed on a decentralized network composed of many peer nodes around the world. Every node is qualified to record and issue this digital currency.
As for the underlying data storage of Bitcoin, it is based on blockchain technology. Each transaction in Bitcoin corresponds to a row in the block data. A simple diagram is as follows:
Each row of the transaction record contains a timestamp, transaction details, and digital signature.
The table is only for ease of understanding. The actual stored transaction details are anonymous, and only the wallet addresses of the payer and payee are recorded.
As for digital signatures, they can be understood as anti-counterfeiting marks for each single transaction, generated by an asymmetric encryption algorithm.
Next let’s talk about the rewards of Bitcoin miners:
The Bitcoin protocol stipulates that miners who mine new blocks will receive rewards. Starting from 2008, it is 50 Bitcoins, and then halved every 4 years. , currently 12.5 Bitcoin in 2018. The new Bitcoins in circulation are all born in this way. No wonder everyone is so eager to mine Bitcoins!
Advantages and Disadvantages of Blockchain
Advantages of Blockchain:
1. Decentralization
Blockchain does not rely on aA central node, the data of the entire system is jointly maintained by all peer nodes in the entire network, and data can be stored and verified. In this way, unless the attacker hacks more than half of the nodes in the entire network, the entire system will not be destroyed.
2. Information cannot be tampered
The data in the block cannot be tampered with. Once the data is tampered with even a little bit, the hash value corresponding to the entire block will change accordingly, and it will no longer be a valid hash value, and the subsequent linked blocks will also be broken.
Disadvantages of blockchain:
1. Excessive consumption of energy
To generate a new block, a large amount of server resources must be used to perform a large number of unnecessary trial calculations, which seriously consumes electricity.
2. Network delay of information
Take Bitcoin as an example. Any transaction data needs to be synchronized to all other nodes. The synchronization process will inevitably be affected by network transmission delay, resulting in a long time consuming.
A few additional points:
1. Part of the content of this comic refers to Ruan Yifeng’s blog post "Blockchain Introductory Tutorial". I would like to thank this great master for his popular science.
2. Due to limited space, the knowledge about Merkle Tree and asymmetric encryption has not been discussed in detail for the time being. Interested friends can check the information for further study.

㈢ What is blockchain? A cartoon to help you understand (a must-read for beginners)

The word "blockchain" was actually used in the early cryptography circles. The underlying technology of Bitcoin is called "Bitcoin". In English, Bitcoin starting with a capital B refers to the network system or network protocol of Bitcoin.

However, due to public confusion, people are now very resistant when talking about Bitcoin, thinking that Bitcoin is synonymous with illegality, scams, pyramid schemes, and another phenomenal bubble in Internet finance! As a result, people had to merge all the underlying technologies (timestamps, proof-of-work mechanisms, etc.). In order to distinguish them from Bitcoin, they renamed them Blockchain, which translated into "blockchain". This is how the term “blockchain” appeared.

Blockchain is not a single technology, but a collection of a series of technologies.

How should we understand blockchain? Let’s first use the love story that everyone loves to talk about as a simple example. Establish a simple blockchain model, then the following situation will occur when falling in love in this blockchain model:

In the future, all men and women of the right age will fall in love and the entire process of marriage commitment will be blocked by all other men and women of the right age. Consensus, all the stories that happen between two people will form a block.

All other men and women are the chain. If a third party intervenes or you violate your partner, others can see it, and you will never find a partner in the future.

Blockchain accurateIt is said to be a "full-center" system, which means that every node on the chain is the center.

Trial marriages for men and women to fall in love, post on friends, show affection, promise to love each other for a lifetime and be known by all other marriageable men and women are the applications of blockchain. If one day one party breaks their promise, don't think that deleting the photos will be useful, because everything is recorded by all marriageable men and women.

Cannot be deleted or changed, this is blockchain technology.

㈣ Are there any easy-to-understand books or articles about blockchain that you would like to recommend?

Blockchain and blockchain technology have been widely accepted and used by people, but I have always had little knowledge about blockchain and blockchain technology, and I am even more confused about the working principle and operation method of blockchain. Maybe you have read a lot of related reports, and there are a lot of professional terms and jargon, but you still don’t have a clear understanding of it. Here Bit Window will explain it to you in a popular way.
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.
This is a professional summary that we usually see in reports, but what is the specific form?
First of all, no matter how big a system or how small a website is, there is usually a database behind it. So who will maintain this database? Under normal circumstances, whoever is responsible for operating the network or system will maintain it.
If it is a WeChat database, it must be maintained by Tencent’s team, and Taobao’s database is maintained by Alibaba’s team. Everyone must think that this approach is natural, but this is not the case with blockchain technology.
Secondly, blockchain technology is also called distributed ledger technology. That is, if we imagine the database as a ledger: for example, Alipay is a typical ledger, and any change in data is an accounting type. We can think of database maintenance as a very simple accounting method.
The same is true in the world of blockchain. Everyone in the blockchain system has the opportunity to participate in accounting. The system will select the person who has the fastest and best accounting during this period, maybe within ten seconds, or ten minutes. This person will do the accounting, and he will record the changes in the database and the ledger during this period. Recorded in a block.
We can imagine this block as a page. After the system confirms that the record is correct, it will link the data fingerprint of the past ledger to this piece of paper, and then send this piece of paper to everyone else in the entire system. . Then the cycle starts over and the system looks for the next person who can do the accounting quickly and well, and everyone else in the system gets a copy of the entire ledger.

Finally, since everyone (computer) has exactly the same ledger, and everyone (computer) has completely equal rights, there will be no loss of contact or downtime due to a single person (computer). And cause the entire system to collapse.
Since there are exactly the same ledgers, it means that all numbersThe data is open and transparent, and everyone can see the digital changes on each account. Its very interesting feature is that the data in it cannot be tampered with. Because the system will automatically compare, it will consider the account books with the largest number of the same number as the real account books, and the small number of account books with different numbers as others are false account books.
In this case, it makes no sense for anyone to tamper with their own ledger, because unless you can tamper with most of the nodes in the entire system. If the entire system only has a few nodes, it may be easy to do, but if there are tens of thousands or hundreds of thousands, and they are distributed everywhere on the Internet, unless someone can control most of the computers in the world, it is not very easy. It is possible to tamper with such a large blockchain.
I wonder if I can understand this simple explanation?

Content introduction:

Blockchain is as sophisticated as a Swiss instrument and as shocking as the Internet. It is subverting society at a god-like pace.

When emerging technologies come, you can choose to avoid them—if you can avoid them tomorrow. The same goes for blockchain.

As a phenomenal concept, financial technology innovation has ushered in a singular development in the past few years. The most eye-catching one is undoubtedly blockchain technology. Blockchain technology is shaking up the global financial infrastructure and is an area that the world's top banks and other financial institutions are pursuing. There is no doubt that blockchain is one of the most promising industries in the next 5 years.

㈥ What is the best blockchain website now?

Generally large information and community websites, such as Babbitt, Golden Finance, Q&A Such as Bikan, Bihu, and some self-media such as Yangtuo Blockchain and Vernacular Blockchain are also very good. You can also search for LinkView.

㈦ What is blockchain? A popular explanation of a new accounting method (you will understand after reading it carefully)

In the past two years, a new accounting method has been circulated on the Internet. The financial model is "blockchain". I think many people still don't understand the meaning of this. After all, "blockchain" is still "advanced" to ordinary people. So what is blockchain? What is the popular explanation? In fact, it is not as complicated as we imagined, so let me tell you what "blockchain" is and see what is special about this model!

What exactly is the "blockchain" that people often talk about? I believe that many people don’t know much about it, and most of the information they view on the Internet is “unclear”. In fact, it is easy to understand. So what is the popular explanation of blockchain? Fundamentally speaking, this model is a "decentralized" accounting method. So what is "decentralization"? All our current exchanges and communications on the Internet will actually be stored in a "centralized" server on a browser or APP. The other party can check our browsing information at will, and "decentralization" is convenient. This can be completely avoided.

Once the information is written into the "blockchain", it cannot be tampered with, ensuring its authenticity and confidentiality. It can also avoid third-party platforms in transactions on the virtual market. Intervention, the transaction is directly completed by both parties, which saves a lot of procedures and time, and also ensures that information is not leaked, transparent and other security issues, and there is no possibility of data loss!

After reading the above introduction, do you have a new understanding of the "blockchain" model? can't read? Let’s take a look at it through a comic below!

Fields of application of blockchain

The "blockchain" model can be applied in many fields, the first of which must be finance. The first blockchain was born from Bitcoin. This new technology can also be used in education, e-commerce, film and television, etc. Now all walks of life are exploring this new field, hoping to have a foothold in the development of the future era!

㈧ Can you recommend any books on blockchain?

There are more and more books in the field of blockchain, and the quality of many books is actually not high. I I recommend two better books that I have actually read and summarized.

A book is "Book Blockchain".

This book is characterized by using interesting and vivid comics to express some principles and applications of blockchain.

This book is especially suitable for newcomers who have just come into contact with blockchain, because the principles in it are analyzed using more real-life cases, which is relatively easy to understand and involves blockchain. Technical knowledge is relatively low.

And this book is not thick, so you can finish it quickly. After all, everyone is very busy at work now. If you read a very thick book, it is indeed difficult to read. This book happens to be more It is thin and light and can easily cultivate your interest in learning knowledge in the blockchain field.

㈨ The "impossible triangle" of blockchain and economics

Continuing from the impossible triangle in economics mentioned at the end of the previous article, here is a popular comic interpretation, which I would like to share with you:

Illustration of Mundell’s Impossible Triangle
< br /> Here is a brief explanation of this impossible triangle:

The impossible triangle refers to an economy’s monetary autonomy, exchange rate stability and free capital flow. One of the three must be discarded. Can't have it both ways.

For example, China is a typical example of giving up the free flow of capital and implementing capital controls in order to implement an independent monetary policy + fixed exchange rate; Hong Kong is a typical example of giving up the free flow of capital in order to implement a fixed exchange rate + free capital flow. In order to implement an independent monetary policy and free capital flow, the United States gave up its fixed exchange rate.

Exchange rate and the 811 exchange reform

First of all, let’s talk about exchange rate stability. It is easier for everyone to understand exchange rate stability. Before the exchange rate reform (811 exchange reform) implemented by China on August 11, 2015, the RMB exchange rate was pegged to a single U.S. dollar system. After the 811 exchange reform, several major currencies were selected and given corresponding weights to form a currency basket. At the same time, changes in the RMB multilateral exchange rate index are calculated based on market supply and demand with reference to a basket of currencies to maintain the basic stability of the RMB exchange rate at a reasonable and balanced level. But referring to a basket does not mean focusing on it. It also requires market supply and demand.relationship as another important basis, based on which a managed floating exchange rate system was formed.

What does the government expect to do after the exchange rate reform? As you can see from this triangle shape, we want to achieve the independence of monetary policy and the free flow of capital. So what does monetary policy independence and free capital flow mean? Monetary policy independence means that the central bank within the economy can formulate monetary policies, decide independently whether to issue or withdraw currency, and regulate liquidity. For a super economy like China, monetary policy must be in its own hands. Free flow of capital means that foreign funds can come in to invest or withdraw capital at will. Then, with the needs of my country's current industrial structure adjustment and the need to continuously expand opening up to the outside world, the liberalization of the capital market is inevitable. Recently, we have seen some relaxation of capital controls, such as the recent announcement to open foreign accounts to enter the A-share market, and the previous announcement to remove restrictions on foreign shareholding ratios in banks and financial asset management companies; securities companies, fund management companies, and futures companies will be , the upper limit of foreign shareholding ratio of personal insurance companies has been relaxed to 51%. We have seen the opening up of China's capital market to the outside world, but this aspect is introduced, but for the policy of domestic capital going out, we currently see that at the government level It is still relatively conservative, especially since last year, domestic capital groups have stopped large-scale mergers and acquisitions of overseas projects, such as Xinhua Airlines, etc. Therefore, for now, the government's domestic capital controls are still strict. Of course, in addition to the investments made by large state-owned enterprises overseas, the overseas investment of capital from large government funds and banks such as the Silk Road Fund and the Asian Infrastructure Investment Bank has been approved at all levels and is subject to stricter controls.

So, the reason why we need to strictly control capital is, on the one hand, to consider the impact of the free flow of capital on our country's economy, and on the other hand, because of the current lack of effective financial supervision means. Regulate capital. As mentioned earlier in "The Three Major Characteristics of Blockchain: Penetration", blockchain is a penetrating technology and a powerful tool for financial supervision. The combination of financial markets and blockchain is an inevitable trend in the future, so with the help of blockchain technology, regulatory agencies can conduct real-time dynamic supervision of capital flows and flows, and aggregate the inflow and outflow of capital into one Network, the so-called Skynet is restored, without omissions; in addition, the regulations in the system design are incorporated into the smart contract of the blockchain. Once there is an abnormal inflow or outflow of funds, an alarm or early warning can be triggered in real time. Of course, friends in the financial sector need to give their opinions on whether complete penetrating supervision is necessary. However, using blockchain technology to regulate the flow of financial capital can greatly reduce the possibility of financial capital doing evil. Once evil is done, the perpetrators can be investigated and punished.

On the other hand, for capital going global, supervision may be more difficult, and issues of international cooperation and supervision need to be taken into consideration. At this time, it is necessary to break through the data islands between countries.It has become necessary to establish a regulatory data sharing mechanism.

By building a regulatory system based on blockchain technology, we see that it will be possible to further realize the free flow of capital, a standardized capital market will gradually form, and a trust mechanism between various entities participating in the capital market will be able to The establishment will help create a fairer international capital competitive environment.

From the perspective of exchange rate changes, it mainly depends on the quality of the domestic economy. Of course, there are also external factors. Combined with the previous analysis of "Blockchain and Economic Cycle", it is expected that credit risk can be effectively controlled under the transformation of blockchain technology, and the volatility of a country's macroeconomics will weaken, so the corresponding fluctuations in the exchange rate market will also become smaller.

So back to the "Impossible Triangle" mentioned at the beginning of the article, with the help of blockchain technology, it is expected that this classic theory may be further rewritten, and the "Impossible Triangle" will also become " "Possible triangle", due to the stability characteristics of triangles, further becomes "reliable triangle".
