1. 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.

2. What are the differences between blockchain and digital currency

Thank you!
Thanks for the invitation!
To know the difference between them, we must first know their definitions.
Digital currency: DIGICCY for short, which is the abbreviation of "Digital
Currency" in English, is an alternative currency in the form of electronic currency. Digital gold coins and cryptocurrency are both digital currencies (DIGICCY).
Blockchain: 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 essentially a decentralized database, also known as a trust machine.
From the above definition, we can know that blockchain is a technology, and digital currency is a kind of virtual currency.
Digital currency is not equal to blockchain
Many people will understand blockchain as blockchain. I want to correct it here. Digital currency is not equal to blockchain. Digital currency is just a distinction. It is an application of blockchain, and some digital currencies may not be applied to blockchain technology.

3. Digital currency and blockchain

Digital currency is a form of expression represented by blockchain 1.0, mainly Bitcoin; as a virtual currency system, Bitcoin The total amount of coins 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 operating for many years, the essence of blockchain, as the underlying technology that supports the operation of Bitcoin, It is an extremely clever distributed shared ledger and point-to-point value transmission technology. It will have a huge potential impact on finance and even all walks of life.ring.
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.

4. What is the relationship between digital currency and blockchain technology?

There is a certain connection between digital currency and blockchain. They are an organic combination. Blockchain is the lowest technology of digital currency, and of course it is also one of the most important technical means. Blockchain is the most widely used and most successful in the field of digital currency. Regarding the application of blockchain technology, digital currency is established on the basis of its technology, and digital currency can also be regarded as a part of blockchain technology.

Blockchain, as a powerful technical support for digital currency, can ensure that cryptocurrency exists in an encrypted form to a certain extent. The relationship between the two can be seen as inclusive. Blockchain technology, as the most basic technical application of digital currency, helps to issue digital currency.

5. 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 senseGenerally speaking, blockchain technology actually uses fast-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 utilizes automation Smart contracts composed of script codes are a new distributed infrastructure and computing method for programming and operating 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.).

6. Are blockchain and digital currency speculation the same concept?

Blockchain and digital currency are not the same concept.
Blockchain is a decentralized database, which is a series of data blocks associated using cryptographic methods. This is a big concept with wide application prospects.
Digital currency is an unregulated, digital currency. It is just an application of blockchain technology and was born based on blockchain technology.
Simply put, digital currency and blockchain are closely linked. Blockchain is the lowest technology and the most important technical means of digital currency. The most successful practice of blockchain is innovation in the currency field.

7. 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 based on blockchain technology.Established on the basis of means, blockchain has a certain guarantee for the security of digital currency. At the same time, digital currency is the most successful application of blockchain technology.
Extended information: 1. Digital currency is an unregulated, digital currency, usually issued and managed by developers, and accepted and used by members of specific virtual communities. 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. .
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.

8. 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.

9. 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 the block. Therefore, almost no information is copiedThe possibility of tampering, as long as almost all nodes cannot be invaded. A block is connected head to tail to form a block chain.

Digital cash is a form of encrypted cash. Because this kind of digital cash needs to be encrypted, digital cash needs Supported by blockchain technology, blockchain technology is also the most advanced technology in the world. Many famous companies in the world are studying this technology. The development prospects of this technology are unlimited

Common misunderstandings

1. Blockchain is Bitcoin

Because Bitcoin is more popular than its underlying technology, blockchain, many people confuse the two. Blockchain is a technology that can be used throughout the entire network. Peer-to-peer transactions are recorded on a distributed ledger. These transactions are stored in blocks, and each block is linked to the previous block, thus making a link.

Bitcoin is digital cash that can be traded directly between two people , not through a third party like a bank.

2. The only application of blockchain is digital cash

Blockchain and digital cash are like peanut butter and jelly. They are excellent together. , they themselves are also very good. Blockchain is not just for purposes. Every enterprise and industry can use the basic technology of distributed ledgers.

3. Information about blockchain activities cannot be Public
