Ⅰ 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 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 and send transactions for validity confirmation, and anyone can participate in its consensus process. Bitcoin and Ethereum are typical applications of public blockchains. Public blockchains are a global Distributed blockchain, blockchain data is open, user participation is high, and it is easy to produce network effects, easy to apply and promote. Therefore, this kind of blockchain operation relies heavily on the incentive mechanism, Bitcoin Tokens such as Ethereum 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 encourage 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.

II What is the relationship between blockchain and digital currency

Blockchain refers to a chain formed by connecting 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, digital currency exists in a digital way. 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.

Ⅲ What does cryptocurrency mean?

1. What is cryptocurrency?
Cryptocurrency is a trading medium that uses cryptographic principles to ensure transaction security and control the creation of transaction units. It is a type of digital currency (or virtual currency). It is based on a set of open source codes of computer calculations around the world, generated through a large amount of computing processing by computer graphics cards and CPUs, and uses cryptographic design to ensure the security of all aspects of currency circulation. Design based on cryptography allows cryptocurrencies to be transferred or paid only by real owners.
The biggest difference between cryptocurrencies and other non-cryptocurrencies is that the total quantity is limited and has extremely strong quantitative scarcity. Because the total amount of open source code for this set of equations is limited, it must be obtained through calculations by the computer graphics card CPU.
Cryptocurrency is based on a decentralized consensus mechanism. As opposed to the banking financial system that relies on a centralized regulatory system, cryptocurrencies do not rely on issuance by legal tender institutions and are not subject to central bank control.
The decentralized nature comes from blockchain technology using distributed ledgers.

2. Blockchain?
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. 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.
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 A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.
From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

IV 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 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. .

IV What is Blockchain and Digital Currency

Characteristics of Blockchain It is decentralized, trustless, collectively maintained, and a reliable database

For example: For example, grandson asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default on the loan, so he asked the village chief to do a notarization , and add this account. This is called centralization. But if, instead of asking the village chief, a loudspeaker in the village shouts, "I, Li Zi, lent my grandson a hundred yuan! Please record it in the account book," this is called decentralization. In the past, the village chief was highly respected and had control of the entire village's ledger, so everyone kept their money with him. This was the trust that everyone had in centralization in the past. Now, everyone is worried that the village chief will secretly misappropriate everyone's money. What should we do? So everyone issued a ledger to everyone, and anyone who transfers money will announce the news through the loudspeaker. After receiving the news, everyone Everyone records the transaction in their own ledgers, which is called decentralization. With the distributed ledger, even if the ledger of Lao Zhang or Lao Li’s family is lost,It doesn't matter, because Lao Zhao, Lao Ma and other families have account books.

The abbreviation of digital currency is DIGICCY, which is the abbreviation of "Digital Currency" in English. It is an alternative currency in the form of electronic money. Digital gold coins and cryptocurrency are both digital currencies (DIGICCY). Blockchain technology services Shengpu Technology

VI What does cryptocurrency mean

Cryptocurrency is a type of digital currency that uses cryptographic principles to ensure transaction security and control. A medium of exchange created by trading units, Bitcoin became the first decentralized cryptocurrency in 2009. Since then, the term cryptocurrency has mostly referred to this type of design. Cryptocurrency is based on a decentralized consensus mechanism, as opposed to a banking financial system that relies on a centralized regulatory system.

The decentralized nature of cryptocurrency originates from the blockchain technology of distributed ledgers. Blockchain is an intelligent peer-to-peer network that uses distributed databases to identify, disseminate and record information. Also known as the Internet of Value. Satoshi Nakamoto proposed the concept of "blockchain" in 2008 and founded Bitcoin in 2009.

The total number of Bitcoins is only 21 million. They are not issued by specific monetary institutions. Their characteristics include decentralization, low transaction fees, global circulation, no hidden costs, exclusive ownership, and cross-platform mining. wait. Anyone can mine, buy, sell or receive Bitcoin regardless of location.

Bitcoin cannot be traded in China. The main price is affected by a variety of factors and is extremely unstable. At the same time, the price of a single coin is around US$10,000, which is simply unaffordable for ordinary users. For example, in 2017, the lowest price of Bitcoin throughout the year was US$775, and the highest price reached US$19,757.

Ⅶ What is digital currency and what field does digital currency belong to

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 by the relevant personnel themselves. Then the editor will explain what exactly digital currency is and what fields it belongs to.

Summary

Because digital currency is an intangible product, it is a currency in people’s perspective and 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 disappear from the market. Therefore, you must be cautious when investing in digital currencies and do not invest large sums of money.

VIII What is the relationship between encrypted digital currency and blockchain?

Encrypted digital currency usually refers to a digital asset issued on the blockchain network. Through the blockchain browser, users can query the entire process of digital currency transactions. In life, we often regard blockchain institutions or projects asThe bank's digital assets are called "encrypted digital currencies", which are fundamentally different from the digital currencies issued by the central bank, that is: the central bank's digital currency is a replacement for M0 and does not itself issue new currencies; while the blockchain project party The digital currency issued is "creating" a currency out of thin air. It lacks the endorsement of a sovereign institution and involves greater credit risk.

From a definition point of view, blockchain is a new form of technology. It has the characteristics of transparency, traceability, and non-tampering, and can empower supply chain finance, product traceability, certificate storage, etc. industry sector. Through blockchain, a trustworthy value network can be established.
