❶ What is digital currency, digital finance and blockchain

From a financial perspective, blockchain and digital currency are actually a new generation of digital financial system. The digital financial system is built on the financial infrastructure of blockchain digital currency.

From the perspective of an enterprise, how do we understand the digital economy?

We know that the driver of the industrial economy is fossil fuels, and the driver of the digital economy is data. So how does data drive a business? I summarize it as computer modeling of data, using algorithms to organize the data, and at the same time computer programming of the company's business processes, turning the data into algorithm models, and then stringing together the algorithm models to turn the business processes into computer programs. Or become a smart contract, which is digital technology. This digital economy is not the digital economy from an economist’s perspective.

How to integrate these things requires a series of digital technologies. A series of digital technologies such as the Internet, Internet of Things, cloud computing, artificial intelligence and blockchain constitute the digital economy, or digital business.

Digital technology has three characteristics. The first is that it spans time and space, because data naturally has the ability to penetrate. For example, cross-border and cross-organization data flow cannot be blocked by national borders, so it crosses time and space. At the same time, data is penetrable. It can penetrate the market vertically, eliminating all intermediaries and hierarchies in the middle, and then Let transactions become peer-to-peer, and buyers and sellers no longer need intermediaries. It can penetrate the market vertically and shorten the industrial chain horizontally. Peer-to-peer, there is no middleman to guarantee the transaction settlement.

The core of digital finance is point-to-point payment settlement and non-guaranteed transaction settlement. Nowadays, using bank cards to buy things in shopping malls is not a point-to-point transaction. It takes time for the merchant to receive the money, and the bank guarantees that the transaction can be settled completely. But if these intermediaries disappear, how can transactions be cleared and settled in real time? At present, blockchain and digital currency are the best technical solutions to solve these problems, and no other better solution has been found yet.

From a business perspective, blockchain technology has its own characteristics, that is, it is sufficiently digital, it is cross-border, cross-time and space, and cross-organization. The flow of data has no boundaries, so the blockchain is distributed at the same time, it is self-organized and decentralized.

So the origin of blockchain and the application of any new disruptive technology have always had two routes, or two methods. One way is to regard it as a tool and use it to improve the traditional business model and obtain an improvement in marginal benefits. The other is to treat it as a system to reconstruct the underlying logic of business.

There is a good example of these two application methods in the past few years. When Internet companies are promoting "Internet +", we also look atMany traditional business organizations say that it is not "Internet +", but "+Internet". So where are those people who shout "+Internet" now? Some people think that the Internet is just a technology used to improve traditional things, and some Internet technologies can be added to traditional things. For example, if you use the Internet as email, you build an email system and think it is the Internet. But some people treat the Internet as a system and reconstruct the business from the bottom up. In the end, you will find that you are unemployed.

The second is decentralization. Why go to the center? Regional center technology in business has brought business decentralization, which is an inevitable trend in history. Where is this trend? I think there are two points. One is economic globalization and entering version 2.0. Now through the Internet, it is no longer the company that is globalizing, nor the company turning itself into a multinational company, but the Internet is empowering any individual, so that it can sell its products through the Internet in a small county in China. worldwide. When economic globalization develops to personal globalization, solving point-to-point transactions and point-to-point services becomes a prominent issue. Then the real-time clearing and settlement and point-to-point transaction settlement brought by blockchain technology can just help the globalization of personal business activities.

The third is the digitalization of the economy. When data is collected to a certain extent, its circulation is basically across time and space. The demand for financial payments from commercial activities is carried with them anytime and anywhere, and it is impossible to provide scenario-based and virtualized payment settlement anytime, anywhere and on demand. Services will eventually be eliminated by technology and the market.

❷ What is a blockchain and what is a blockchain in digital currencies

In a narrow sense, a blockchain is a way of connecting data blocks sequentially in chronological order. A
chained data structure composed of
and cryptographically guaranteed distributed ledger that cannot be tampered with or forged. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing paradigm that uses smart contracts composed of codes to program and manipulate data.
Now, mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea-based digital currency Puyin was developed based on blockchain technology.

❸ What is the relationship between blockchain and digital currency

Blockchain refers to a chain connected by a series of data blocks (i.e. blocks). The connection method is: The N+1 block contains the hash value of the N block. Moreover, such a chain of data blocks is simultaneously stored and maintained by a widely distributed and huge number of server nodes. Each server node has a complete copy of the blockchain. Digital currency is another form of existence and circulation of legal currency.Compared with the banknotes and coins currently in circulation, it exists in a digital form. The legal existence of digital currency is legal and is based on blockchain technology. Blockchain is the underlying technology for digital currency issuance. This is also the most direct relationship between the two. They can exist independently of each other.

❹ In your opinion, do digital currencies and blockchain belong to the same concept?

< p>Blockchain and digital currency are inextricably related, but they are not equivalent.

Most people know that blockchain should have started with Bitcoin, which became popular on the Internet some time ago. Bitcoin is actually one of the application scenarios of blockchain technology. Bitcoin is also the hottest number in the world. Currency, but blockchain is not the same as digital currency. Digital currency is only one of its application scenarios. The past few years were when blockchain technology exploded. Blockchain technology will change many aspects of life

Although the first generation of digital currency, namely Bitcoin in the blockchain 1.0 era, is one of the most mature application projects of blockchain technology, it cannot be said that blockchain is Bitcoin. Blockchain is the underlying architecture technology. It itself does not have any actual value. Even if it is in the same space, it has no value. But when its characteristics are combined with the online Internet and offline real economy, its value is infinite. No matter whether digital currency evolves to blockchain 2.0 or 2.1, it cannot escape the essence of digital currency, which is essentially different from blockchain. To put it bluntly, blockchain is a panacea, while Bitcoin can only be regarded as a business representative.

❺ What are the top ten most popular digital currencies at the moment

Bitcoin, Ethereum, Ripple, Bitcoin Cash, EOS6, Litecoin, Stellar Lumens, and Cardano , Tether, IOTA

1. Bitcoin was launched by Japanese Satoshi Nakamoto on November 1, 2008, and was officially born on January 3, 2009! Bitcoin is a virtual encrypted digital currency in a P2P situation. Point-to-point transmission means a decentralized payment system! Since it is a virtual currency, it is definitely not issued by a specific institution, but generated through a specific method and a large amount of calculations! Because the total amount is relatively small, its scarcity is very high, and the number is now permanently limited to about 21 million!

2. Ethereum: Ethereum is an open source public blockchain platform with contract functions. Through its dedicated cryptocurrency Ethereum, it is also a decentralized virtual machine to handle peer-to-peer transactions. contract! It was proposed by programmer Vitalik Buterin in 2013 after being inspired by Bitcoin. It was developed in 2014 and is now the cryptocurrency with the second highest market value after Bitcoin!

3. Ripple currency: Ripple currency is the basic currency of the Ripple network. It circulates throughout the entire Ripple network. The total amount is about 100 billion, and the number increases with the number of transactions.It will gradually decrease! Last year, Ripple surpassed Ethereum in a short period of time to become the world's second most valuable virtual currency!

4. Bitcoin Cash: It is a new encrypted digital asset launched by ViaBTC, a mining pool owned by the mining giant Bitcoin Continent, based on the BitcoinABC plan. It can be regarded as a fork of Bitcoin BTC or It’s an altcoin! Its purpose is to alleviate Bitcoin’s network congestion problem!

5. EOS: It is a blockchain operating system designed for commercial distributed applications. It is similar to the Winds operating system and can support multiple applications operating at the same time, aiming to achieve distributed New application extensions! But it is not a currency like Bitcoin and Ethereum, but a token released based on the EOS software project, and there are no handling fees, so it has a wider audience!

6. Litecoin: It is also a virtual currency inspired by Bitcoin. Its creation and transfer are based on an open source encryption protocol and are not managed by any central agency. Designed to improve Bitcoin, the circulation is more than four times that of Bitcoin!

Seven Oaks and Stellar Lumens: It is a basic currency circulating in the Stellar Network. The Stellar Network is developed based on the Ripple Network. However, the Stellar Network and the Ribo Network are classified as pyramid schemes in China. Distribution is not allowed!

8. ADA Coin: A virtual currency born in 2015, with a total amount of 4.5 billion. This digital advanced represents the currency of the future. Through encryption technology, it can be faster. Direct transfers ensure security!

9. Tether: It is a virtual currency launched by Tether that links cryptocurrency to the legal currency US dollar. It is a virtual currency that is stored in a foreign exchange reserve account and supported by legal currency! 1 Tether is equal to 1 US dollar!

10. 10. IOTA: It is a new type of digital cryptocurrency that focuses on solving transaction problems between machines. It is more efficient, secure and real-time micro-transactions and does not generate No transaction fees!

❻ What are digital currencies?

As of July 18, 2020, Fanyu has a total of 5,740 global encrypted digital currencies and 23,280 trading markets. , with a total market value of 1.89 trillion yuan. The top five digital currencies are Bitcoin, Ethereum, Tether, Ripple, and Bitcoin Cash, with current market values ​​of 1.18 trillion, 182 billion, 64.2 billion, 60.3 billion, and 28.8 billion respectively.

Although cryptocurrencies such as Bitcoin and Ethereum still have a market worth trillions in the global market, because they are decentralized virtual currencies that are independent of national credit, in order to To prevent systemic financial risks, my country has been taking increasing actions to crack down on all non-legal digital cryptocurrencies, banning ICOs, RMB and digital currencies.transactions, guide mining companies to exit, and ban access to websites involving cryptocurrency transactions nationwide.

❼ What is blockchain and what is digital currency

Blockchain is an important concept of Bitcoin and is essentially a decentralized database.
At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information. (anti-counterfeiting) and generate the next block. Digital currency is an unregulated, digital currency that is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking Authority defines virtual currency as: a digital representation of value that is not issued by a central bank or authority and is not linked to a legal currency, but which, because it is accepted by the public, can be used as a means of payment or can be transferred, stored or traded electronically. .

❽ What is digital currency

Digital currency is the product of blockchain technology , mentioning digital currency is inseparable from blockchain technology. Blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness.
From a financial accounting perspective, blockchain can be seen as a highly credible network electronic ledger in which all nodes participate. Compared with WeChat, Alipay and other application systems, there is a large central database account book behind them; the blockchain implements network-wide collaborative accounting and verification, and all nodes participate in accounting. Each time accounting is done, a new block will be formed, namely Block; each block can only be packaged by one node. After solving a mathematical problem (hash algorithm Hash) to determine that the information is legal, it will be broadcast to the entire network, adding to the end of the previous block and recorded by other nodes. The ledger chain formed in chronological order is the blockchain. In order to motivate bookkeepers (that is, those who pack blocks), the system will give certain digital currency rewards, and this process is mining. Since the design and generation mechanism of digital currency determines that the quantity is limited, it forms the basis for the consensus that digital currency has value.
Digital currency is based on digital principles and is a network virtual currency generated through large-scale calculations through specific algorithms. The European Banking Authority defines virtual currency as: a digital representation of value that is not issued by a central bank or authority and is not linked to a legal currency, but which, because it is accepted by the public, can be used as a means of payment or can be transferred, stored or traded electronically. . This is the earliest concept of digital currency. With the development of technology, the concept of digital currency has gradually been extended, not only limited to the use of blockchain technology. In our country, digital currency in the official sense refers to the central bank's legal digital currency, that is, the digital currency issued by the central bank, which is a liability of the central bank, has national credit, and is equivalent to legal currency.
[Extended information]
1. China issuance figuresThe Importance of Currency
The current economic society is a highly developed credit economy. Non-statutory digital currencies with defective currency issuance and management functions are difficult to take on major responsibilities. The core problem is that it is difficult for such transferable digital assets to build their own value. support system. From the nature of currency, only the state can exercise the highest power to issue currency. For sovereign countries, the best way to practice the country's right to issue currency is for the government and the central bank to issue sovereign digital currencies within the control scope. The launch of digital currency by my country's central bank has important breakthrough significance.
To sum up, the central bank’s promotion of digital currency has four major significances:
1. Accelerate the internationalization of the RMB. The current mainstream cross-border clearing model in the world is through the SWIFT system led by the United States. In the future, the central bank's digital currency may flow out of the country, which can partially accelerate the internationalization of the RMB, replace the offshore RMB/IMF Special Drawing Rights, create the central bank's international digital credit assets, and become a means of cross-border settlement.
2. Influence monetary policy more efficiently. The pricing standards for currency are clearer, thereby greatly improving the accuracy, timeliness and effectiveness of currency prices. The emergence of legal digital currencies can provide new monetary policy tools to support central bank management.
3. Real-time centralized collection of currency flow data. The issuance of central bank legal digital currency will also make it possible to collect data on currency creation, accounting, flow and other data in real time.
4. Currency tracking helps with anti-money laundering and counter-terrorism.

❾ What is the relationship between blockchain and digital renminbi

Differences:
1. Blockchain and digital currency complement each other and are inseparable. Blockchain is the circulation of digital currency. One of the means.
2. Blockchain is the theoretical basis of digital currency. Digital currency is established on the basis of blockchain technology. Blockchain has certain guarantees for the security of digital currency. At the same time, digital currency is a block chain. The most successful application of chain technology.
Since the concept of "digital renminbi" was proposed, digital renminbi has often been compared to cryptocurrencies such as Bitcoin and Ethereum that use blockchain technology. So let’s first figure out what is digital renminbi?
Digital RMB is a legal currency in digital form issued by the People's Bank of China. It is operated by designated operating agencies and redeemed by the public. It is based on a broad account system and supports the loose coupling function of bank accounts. It is compatible with paper Banknotes and coins are equivalent, have value characteristics and legal compensability, and support controllable anonymity.
The concept of digital renminbi has two key points. One is that digital renminbi is a legal currency in digital form; the other is that it is equivalent to banknotes and coins. Digital renminbi is mainly positioned at M0, which is cash and currency in circulation. coin.
But in fact, the digital renminbi only draws on blockchain technology, but as a legal currency, the digital renminbi has centralized characteristics. Executives from major European central banks said that issuing central bank digital currencies does not actually require the use of blockchain technology. The core elements of the digital RMB system framework are “one currency, two treasury."Three Centers", the technologies used in the use process include NFC and distributed ledger technology.
02 What is blockchain technology?
In a broad sense, blockchain technology is actually the use of fast chain technology Data structures are used to verify and store data, distributed node consensus algorithms are used to generate and update data, cryptography is used to ensure the security of data transmission and access, and smart contracts composed of automated script codes are used to program and operate data. A new distributed infrastructure and computing method.
03 Digital RMB just draws on blockchain technology
Digital RMB has the same characteristics as blockchain technology, such as traceability and non-tamperability, etc. .As a legal currency issued by the state, the most important feature of the digital renminbi is the "centralized management model", and one of the core features of the blockchain is "decentralization".
Previously, many countries have also issued relying on Digital currencies based on blockchain technology, such as Uruguay, Iran, Senegal, etc., have not become popular.
Executives of major European central banks stated in September 2020: If central banks around the world If you want to issue digital currency, you don't actually need to use blockchain technology. The central bank provides "trust" for the central bank's digital currency, so after the central bank intervenes, there is no need to use blockchain technology.
In Finance In terms of fields, blockchain technology currently has corresponding experimental and small-scale applications in digital currency, payment and clearing, digital bills, etc.
04 “One currency, two treasury, three centers”
Previous It is mentioned that the core elements of the digital RMB system framework are "one currency, two treasury, and three centers." Here we will briefly explain "one currency, two treasury, and three centers." The "one currency" here actually refers to the central bank's digital currency Currency; the "two libraries" refer to the digital currency issuance library (the database that stores the central bank's digital currency issuance fund) and the digital currency bank library (the database where commercial banks store the central bank's digital currency); the "three centers" refer to the certification center (responsible for Identity information management), registration center (responsible for digital currency ownership registration) and big data issuance center (responsible for analysis of anti-money laundering, payment behavior, etc.).

❿ What is digital currency and what fields does digital currency belong to< /p>

I believe many people have heard of electronic currency and banknotes, but there are still many people who have not heard of digital currency. In fact, digital currency is also a type of currency, but this currency is not issued by the government. , but issued by the relevant personnel themselves. Then the editor will explain what exactly is digital currency and the field to which digital currency belongs.

Summary

< p>Because digital currency is an intangible product, a currency from people’s perspective, it cannot be circulated and used in the market. If no one is willing to invest in it, then it will have no value and may be withdrawn from the market. Disappear. Therefore, you must be cautious when investing in digital currencies and do not invest large sums of money.
