① Is blockchain a digital currency?

No, blockchain and digital currency are different.
Blockchain is the underlying technology of digital currency. Digital currency is issued based on blockchain. Many people are familiar with blockchain because of digital currency, so they confuse them, but in fact the two have completely different meanings. Crypto Finance Learn more blockchain news.

② What is the blockchain digital currency industry

Blockchain digital currency is an encrypted digital currency, that is, digital RMB, and its functions are not limited to payment tools. Digital currency is the initial application tool of blockchain. There is digital currency first, and then there is blockchain.
The blockchain is connected by a series of blocks generated using cryptographic algorithms. Each block is filled with transaction records, and the blocks are connected in order to form a chain structure, which is the blockchain ledger. The new hash value and nonce need to be calculated based on the hash value of the previous block, the new transaction block and the nonce. That is to say, each block is generated based on the data of the previous block. This mechanism ensures the uniqueness of the blockchain data.
In the financial field, digital currency has shown its unique application benefits, which has led to its development in cross-border payments, currency exchange, payment settlement and other fields. However, it also has limitations, so it has not gained people's attention. recognized.

1. What is the use of blockchain digital currency?
1. Economic significance.
Blockchain can cause the cost of transaction activities to decrease, and the time, money and manpower invested by the unit will decrease. In other words, the first thing blockchain brings is improved efficiency, and improved efficiency means savings. It is estimated that it can save more than 10,000 times the cost. Blockchain has also caused an increase in the proportion of small-value currency transactions. For example, Alipay and Yu'E Bao created by Alibaba are essentially a disguised blockchain, forming a contract between the public and Alibaba. Alibaba is not a bank, but it has some functions of a bank and represents the evolution direction of the financial system.
2. Social significance.
Blockchain will reorganize the market, reorganize society, and reorganize the relationship with users. Blockchain will also promote the self-organization of social members. Blockchain participants are free and not forced. We can imagine that one day, people realize their needs through various forms of blockchain, which means the formation of a new social operating system. At least, it's theoretically possible.
2. What is the significance of blockchain digital currency?
The contemporary economy faces many problems, the most important of which is that it is difficult for the country to fundamentally solve the problem of stabilizing the economic basis of legal currency. This situation became more serious after the collapse of the "Burton Woods monetary system".
Take China as an example. In the early 1980s, 1 penny was money, and 10,000 RMB was already the standard for the rich. Today, the unit of money is yuan, and cents have lost their meaning. 1 yuan is 100 times 1 cent. Therefore, in the past, 10,000 yuan meant a rich person, but now it needs to be multiplied by at least 100Times, that's 1 million.
Actually, 1 million is of limited use. In first-tier cities, 1 million RMB can only buy a house of 20 to 30 square meters. When the financial crisis broke out in 2008, major countries implemented a loose money supply system. Not only did their own currencies depreciate, they also led to the devaluation of other countries' currencies. People had to bear the consequences of currency depreciation and inflation.

③ Is digital currency a blockchain?

Blockchain is a technology that can be applied by anyone and any organization.
Digital currency uses blockchain technology.

④ What is the relationship between blockchain and digital RMB

Difference:
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 databases, and 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 actually uses fast-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 security, a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.
03 Digital RMB just draws on blockchain technology
Digital RMB has the same characteristics as blockchain technology, such as traceability and non-tamperability. 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 issued digital currencies relying on blockchain technology, such as Uruguay, Iran, Senegal, etc., but none of them have become popular.
Executives of major European central banks stated in September 2020: If central banks around the world want to issue digital currencies, they do not actually need to use blockchain technology. Central banks provide central bank digital currencies. "Trust", so after the central bank intervenes, there is no need to use blockchain technology.
In the financial field, currently blockchain technology has received corresponding experimental and small-scale applications in digital currency, payment and settlement, digital bills, etc.
04 “One coin, two treasury, three centers”
As mentioned earlier, the core elements of the digital RMB system framework are “one currency, two treasury, three centers”. Here we will briefly explain “one coin, two treasury, three centers”. Two warehouses, three centers.” The “one currency” here actually refers to the central bank’s digital currency; the “two databases” refer to the digital currency issuance database (the database that stores the central bank’s digital currency issuance fund) and the digital currency bank database (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.).

⑤ What is the relationship between blockchain and digital currency

Digital currency is an application of blockchain.
Blockchain is the core supporting technology of the digital cryptocurrency system represented by Bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transactions based on decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Coordination and collaboration thus provide solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.
Taking the tourism industry as an example, blockchain applications are mainly focused on travel, travel community reviews, digital identity management, credit consumption management, tracking pilots’ professional certificates and qualifications, hotel and airline loyalty programs, and reservations. Management and consumption points management are several application areas. In addition, blockchain also has applications in finance, games, entertainment and other fields.

⑥ The relationship between digital currency and blockchain

1. Blockchain and digital currency complement each other and are inseparable. Blockchain is one of the means of digital currency circulation.
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.
Extended information: 1. NumbersCurrency 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 tender, 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. .
2. Digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency mainly reflect three aspects: ① Because it comes from certain open algorithms, digital currency has no issuing entity, so no person or institution can control its issuance; ② Since the number of algorithm solutions is determined, the digital currency The total amount of currency is fixed, which fundamentally eliminates the possibility of inflation caused by excessive issuance of virtual currency; ③ Since the transaction process requires the approval of each node in the network, the transaction process of digital currency is safe enough.
3. The blockchain shared value system was first imitated by many cryptocurrencies, and improvements were made in proof of work and algorithms, such as the use of proof of equity and SCrypt algorithms. Subsequently, the blockchain ecosystem continued to evolve around the world, with the emergence of initial coin offerings (ICO); the smart contract blockchain Ethereum; the asset tokenization sharing economy with “light ownership, heavy usage rights”; and blockchain countries. People are using this shared value system to develop decentralized computer programs in all walks of life and build decentralized autonomous organizations and decentralized autonomous communities around the world.

⑦ In your opinion, do digital currency and blockchain belong to the same concept?

There are countless connections between blockchain and digital currency relationship, 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.

⑧ Digital currency and blockchain

Digital currency is a form of expression represented by blockchain 1.0, mainly Bitcoin; as a virtual currency system, Bitcoin TotalThe amount is limited by the network consensus protocol. No individual or institution can change or modify the supply and transaction records. Therefore, after the Bitcoin network has been successfully running for many years, the blockchain, as the underlying technology that supports the operation of Bitcoin, is essentially a Extremely clever distributed shared ledger and peer-to-peer value transmission technology. It will have a very large potential impact on finance and even all walks of life.
The application of technology represented by smart contracts in Blockchain 2.0
The era of Blockchain 3.0 has arrived. The model of collaborative operation of blockchain can be seen behind the operation of all walks of life. Therefore, the blockchain The chain will definitely change human life extensively and profoundly, so the entire life service will enter the blockchain era. In this Internet development process, blockchain + physical industries, blockchain e-commerce, and blockchain community operations can all apply blockchain technology.

⑨ What is digital currency blockchain

1. Blockchain is a ledger that records digital currency transactions
Take Bitcoin as an example. It has no physical form, but It exists in a special ledger. All Bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of Bitcoins owned by each user. If a person owns Bitcoin, it means that transaction records related to him can be found in the ledger.
The ledger mentioned here is a piece of software, which we can download from the official Bitcoin website, and the underlying technology used in this software is the blockchain. To facilitate understanding, we usually say that the blockchain is the ledger.
The reason why blockchain is used as the underlying technology of the ledger is to achieve the decentralization of digital currency. It can be said that the starting point for a series of problems encountered by digital currencies and the solutions provided comes from decentralization.
2. Blockchain is a technology that ensures the safe use of digital currencies. Everyone knows that blockchain technology has two major characteristics: encryption and non-tamperability, which can reduce the probability of errors during the use of digital currencies. reduced to 0. Since digital currencies have higher requirements for encryption, blockchain technology must be used to support them. Currently, not only many industries in our country are using blockchain technology, but many foreign countries are also actively using blockchain technology. Blockchain technology.
[Extended information]
Blockchain is the underlying technology of digital currency, and Bitcoin is the first successful application of blockchain.. To understand this problem, we must first recognize the facts: not all blockchains require Issuing digital currency, currently our country strongly supports "coinless blockchain". Generally speaking, public blockchain, that is, public chain, needs to issue tokens as "rewards" to motivate users and maintain system operation, while ordinary blockchain , often called a consortium chain, can or cannot be issued. Private blockchains are mostly used for company internal audits and generally do not need to issue coins. The following is a detailed explanation of the differences between the three blockchains:
1. Public block Chain: A blockchain in which anyone in the world can read, send transactions for validity confirmation, and anyone can participate in its consensus process. Bitcoin and Ethereum are examples of public blockchains.The application of public blockchain is a fully distributed blockchain. The blockchain data is open and user participation is high. At the same time, it is easy to produce network effects and is easy to apply and promote. Therefore, this kind of blockchain operation is very important to a large extent. Relying on incentive mechanisms, tokens such as Bitcoin and Ethereum are used as "rewards" for incentives, so public chains need to issue tokens to maintain their own development and ecology.
2. Community Blockchain (Alliance Chain): It means that the participation of nodes in the blockchain is selected in advance. There are usually good network connections and other cooperative relationships between nodes. The data on the blockchain can be open It can also be internal. For partial distribution, we can regard it as "partial decentralization". Each alliance in the chain has its own centralized management. For example, R3CEV of more than 40 banks is a typical alliance chain. Chains usually do not require a lot of money, but there are also individual alliance chains that choose to send money to motivate members within the alliance to contribute, so there are no restrictions on the chain.
3. Private blockchain: refers to a node with a limited scope of participation, such as a specific organization’s own users, strict permission management for data access and use.. Write permissions in a completely private blockchain It is only in the hands of the participants, and the read permission can be opened to the outside world or restricted to any extent. It is currently mainly used for internal audit work of the company. Therefore, the private chain does not need to issue currency, and it does not have the characteristics of decentralization. It is a kind of centralization management mechanism.
