B. The relationship between blockchain and digital currency What is the relationship between digital currency and blockchain

1. Digital currency and blockchain are organically combined. Closely connected, blockchain is the lowest technology and the most important technical means of digital currency. The most successful practice of blockchain is innovation in the field of currency. As one of the technologies of digital currency, the use of digital currency also includes mobile payment, trusted and controllable cloud computing, cryptographic algorithms, etc. The popularity of Bitcoin has made people Understand the technical framework and broad application prospects of blockchain.

2. Blockchain is actually an emerging digital accounting book. This kind of accounting book has powerful functions and is equivalent to a cloud storage function. Because after each transaction for a certain period of time is completed, Record all transactions within this period and make complete copies at all settlement points. This is a "block". Therefore, there is almost no possibility of information being tampered with, unless there is a way to hack into almost all nodes. Blocks are connected end to end to form a blockchain.

3. The biggest feature of digital currency is that it is programmable. It is a computer program and a piece of code. Because it can be programmed, it is an intelligent currency. Because it is intelligent, settlement confirmation and clearing transactions are completed at the same time.

4. Everything has evolved from programmable currency to programmable finance, and from programmable finance to programmable economy.

5. To sum up, digital currency is a form of encrypted currency. It is precisely because this digital currency needs to be encrypted that it exists. Therefore, digital currency needs to be distinguished. Supported by blockchain technology, blockchain technology is also the most advanced technology in the world. Many well-known companies in the world are studying this technology. The development prospects of this technology are unlimited.

C. What are the applications of blockchain industry?

Take the tourism industry as an example. Blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, and credit consumption management. , tracking pilots’ professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumption points management are several application areas. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry.Impact. In addition, blockchain also has applications in finance, games, entertainment and other fields.

D. What is the popular explanation of blockchain? You must know these five application scenarios of blockchain!

Recently, blockchain has become popular overnight, and everyone around is discussing blockchain.

So, is the blockchain the same as Bitcoin?

In fact, Bitcoin and blockchain are not the same thing.

Blockchain is the underlying technology of Bitcoin, but the first usage scenario after the birth of blockchain is Bitcoin.

Bitcoin is just a string of data in a computer. Compared with paper currency, it is also called a "virtual currency". To put it simply, you can understand that Bitcoin is just a string of numbers with cash value, similar to Q coins. In other words, Bitcoin has no actual value. Its current value is supported by the faith of currency speculators. If the faith is gone, the value of Bitcoin will collapse.

What is blockchain? What are the characteristics of blockchain technology?

Let’s first take a look, why is blockchain called blockchain?

Data is stored piece by piece, and the data stored piece by piece is called a block. Different blocks are linked to the previous block, which is called a blockchain.

For example:

On a certain day of a certain year, Lao Wang lent Xiao Wang 10,000 yuan, and Lao Wang told everyone around him the news , the transfer records were posted on WeChat Moments, and everyone helped them testify to the existence of this transaction.

Lao Wang and Xiao Wang are two nodes. These two nodes generate transaction time, location, person and other information, and they are packaged to form a "block". Lao Wang’s friends are also nodes. These nodes jointly record the transaction status and details (blocks) of the two nodes Lao Wang and Xiao Wang. These blocks are connected to form a blockchain.

Fundamentally, blockchain is a distributed ledger database.

What does distributed ledger mean?

Let’s take a look at the traditional accounting method.

The traditional accounting method is a centralized accounting method. For example, if Lao Wang lent 10,000 yuan to Xiao Wang, if Lao Wang did not tell the world about this money, then this amount would Only Lao Wang knows about the money transactions, Xiao Wang knows, God knows, and Earth knows. This accounting method is a centralized accounting method. This method has a very fatal shortcoming: what should I do if the other party does not acknowledge the account? In fact, in real life, in spontaneous private lending relationships, there is no evidence when the lending relationship occurs, resulting in many cases where the other party does not acknowledge the debt afterwards.

oldThe accounting method adopted by Wang from the beginning has prevented future troubles. This method is the blockchain distributed ledger, which has the characteristics of decentralization. Everyone is the center and everyone can testify. The existence of a transaction.

In addition to the characteristics of decentralization, blockchain also has the characteristics of being immutable. In the blockchain, if the data in any one block changes, even if it only changes a punctuation mark, it will become invalid and needs to be recalculated. Therefore, in the blockchain technology, once a piece of data changes, the cost will be Very big. Unless all nodes in this blockchain have 51% control. Therefore, the blockchain system will be stable and secure.

It’s still Lao Wang and Xiao Wang. If Xiao Wang wants to default on his debt, he can’t tamper with it unless he bribes everyone in the world who knows about the transaction.

Blockchain is also open and transparent.

In blockchain technology, all data is public, which is still the case of Lao Wang and Xiao Wang.

If Xiao Wang does not acknowledge the money, once this news is released, then Xiao Wang’s reputation will be ruined. He can only release new news and wash away the money by paying back the money. Clear your own identity.

Some people say that if the blockchain is so powerful, will my identity information be revealed and there will be no privacy? In fact, the blockchain has the characteristics of anonymity and protects our privacy very well. Unless required by legal regulations, technically speaking, the identity of each block node does not need to be disclosed or verified and can be done anonymously.

What are the applications of blockchain?

The origin of blockchain is to solve the problem of trust, and one of the most successful applications of blockchain is digital currency. Bitcoin is arguably the most successful application of blockchain so far.

In addition to digital currency, the future applications of Bitcoin are still very wide, and blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc., promoting different industries to quickly enter the "blockchain+" era.

1. Payment and clearing

The role of the intermediary bank can be abandoned, point-to-point payment can be realized, intermediary fees can be reduced, and fund utilization can be accelerated.

2. Product traceability

For example, if we buy a piece of clothing on a certain website, we can see the past and present life of this piece of clothing.

3. Securities trading

Traditional securities trading requires the coordination of four major institutions, which is inefficient and costly. Blockchain technology can independently complete one-stop services.

4. Supply chain

Apply blockchain technology toIntroducing the supply chain system, synchronizing information within the system can control all links, better complete division of labor and collaboration, and facilitate subsequent accountability.

5. Intellectual property rights

With copyright on the chain, our photographic works, musical works, literary works, etc. will become our information, and the ownership of the information will be confirmed and become our property.

E. What are the application scenarios of blockchain?

I have seen a lot of information about blockchain on the soon-to-be-launched blockchain. Blockchain will make the information Internet more accessible. As the value of the Internet changes, Kuaishangline has accumulated a lot of experience in these technologies and has made great efforts in Internet finance. Go online soon.

F. Di Gang: The central bank is actively exploring the application of digital RMB blockchain

On September 10, the 2021 China (Beijing) Digital Finance Forum was held in Lize Financial Business District, Fengtai District, Beijing. Di Gang, deputy director of the Digital Currency Research Institute of the People's Bank of China, delivered a keynote speech at the parallel forum "Blockchain Empowers High-Quality Development of the Digital Economy". He said that the Digital Currency Research Institute of the People's Bank of China is actively exploring the application of digital RMB blockchain. At the issuance layer, a unified distributed ledger is built based on the blockchain, which improves the efficiency of reconciliation; at the same time, the blockchain has certain advantages in solving trust issues, and technical decentralization does not mean management decentralization.

Di Gang believes that the application of blockchain in the financial field mainly includes two aspects: endogenous improvement and external empowerment: in terms of endogenous improvement, there are supply chain finance, agricultural finance, trade finance and general public finance. Benefit finance and other applications; in terms of external empowerment, financial institutions also provide services for smart cities, "agriculture, rural areas and farmers" and people's livelihood.Provides better blockchain application services in other fields.

According to reports, the Digital Currency Research Institute has actively strengthened the construction of the blockchain standard system and has led multiple domestic and foreign standardization organization working groups and standardization projects to promote the formulation of blockchain standards.

Regarding the application of blockchain technology, Di Gang proposed four major principles: talk less about subversion, talk more about scenario applications, use technology to solve industry pain points; be rational and pragmatic, and integrate various mature and advanced technologies to achieve results Optimal, this is also the starting point for adopting a mixed technology architecture for digital RMB research and development; technology is neutral; neither overestimate nor underestimate blockchain, solving problems is the starting point for applying blockchain technology.

In order to empower the high-quality development of digital finance, Di Gang believes that the current blockchain can achieve breakthroughs in eight aspects, including increasing basic theoretical research, mastering core technologies, and formulating core technical standards.

G. The difference between blockchain and digital currency

When it comes to blockchain, digital cash comes to mind. In fact, the two are different. The difference between blockchain and digital cash is What?

The organic combination of digital cash and block chain is closely related. Block chain is the most basic technology and the most important technical means of digital cash. The most successful practice of block chain is innovation in the currency field. As a One of the technologies of digital currency, the use of digital currency includes mobile payment, reliable cloud computing, cryptographic algorithms, etc. The popularity of Bitcoin has informed the technical framework and broad application prospects of the blockchain.

< p>The block chain is actually the digital bookkeeping book of Xinxingqianma Chain. This bookkeeping book has powerful functions and is equivalent to the cloud storage function. Every time a transaction is completed for a certain period of time, all transactions within that period of time will be recorded and Completely copied on all nodes. This is a block. Therefore, there is almost no possibility of information being tampered with, as long as almost all nodes cannot be invaded. A block is connected head to tail to form a block chain.

Digital Cash It is a form of encrypted cash. Because this kind of digital cash requires encryption, digital cash requires the support of blockchain technology. Blockchain technology is also the most advanced technology in the world. Many famous companies in the world are studying this technology. This technology The development prospects are unlimited

Common misunderstandings

1. The blockchain is Bitcoin

Since Bitcoin is more popular than its underlying technology blockchain, many People confuse the two. Blockchain is a technology that records peer-to-peer transactions on a distributed ledger across the entire network. These transactions are stored in blocks, and each block is linked to the previous block, thus making a link.

Bitcoin is digital cash and can be traded directly between two people without going through a third party like a bank.

2. The only application of blockchain is digital cash

< p>Blockchain and digital cash are like peanut butter and jelly. They are great together and they are great on their own. Blockchain is more than just a purpose. Every business and industry can use the underlying technology of distributed ledgers .

3, Information on Wuchi blockchain activities cannot be disclosed
