㈠ 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, so in the past, 10,000 yuan meant a rich person, but now it needs to be multiplied at least 100 times, which is 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.

㈡ What is digital currency blockchain

1. Blockchain is a ledger that records digital currency transactions
Take Bitcoin as an example. It does not have a physical form, but exists in a dedicated in the 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. Chaining is usually not requiredIt costs a lot of money, but there are also some 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.

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.

㈣ What is blockchain

What is blockchain? What changes will it bring to your future life?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

On January 10, 2019, the Cyberspace Administration of China released the "Blockchain"Chain Information Service Management Regulations" will come into effect on February 15, 2019.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. Fake distributed ledger.

So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will be carried out with blockchain as the underlying logic. Many things We all have it at our fingertips, and with the integration of artificial intelligence and big data, we can easily handle things that may seem cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.

To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages them into a whole; putting it on an infrastructure to run.

㈤ What is blockchain and how to make money with blockchain

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the price difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, providing blockchain technical support to some teams and enterprises;
6. Opening a trading website and charging handling fees;
7. Developing wallets and wallets It is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain;
8. Be a blockchain project or infrastructure equipment supplier.

Warm reminder: The above explanation is for reference only and does not make any suggestions. There are risks in entering the market, so investment needs to be cautious. Before making any investment, you should ensure that you fully understand the investment nature of the product and the risks involved. After understanding and carefully evaluating the product, you can make your own judgment on whether to participate in the transaction.

㈥ What is blockchain and how to explain it in an easy-to-understand manner

Blockchain is actually equivalent to a disintermediated database , is composed of a series of data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of the information and generate the next block.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be inextricable. Tamper-proof and unforgeable distributed ledger.

In a broad sense, blockchain is actually a distributed infrastructure and computing method, which is used to ensure the security of data transmission and access.

Blockchain classification

Public

Public Block Chains (Public Block Chains) refer to: any individual or Any group can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is only one blockchain corresponding to this currency in the world. .

Consortium

Industry Block Chains (Consortium Block Chains): Multiple pre-selected nodes are designated within a certain group as bookkeepers, and each block is generated by all pre-selected nodes. Nodes jointly decide (pre-selected nodes participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (it is essentially still managed accounting, but becomes distributed accounting, how many pre-selected nodes, how to decide each The bookkeeper of the block becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.

Private

Private Block Chains: Only use the general ledger technology of the blockchain for accounting. It can be a company or an individual, and it can be used exclusively. The write permission of the blockchain is not much different from other distributed storage solutions. (Dec2015) Conservative giants (traditional finance) all want to experiment with private blockchains, while public chain applications such as Bitcoin have been industrialized, and private chain application products are still being explored.

(7) Overview of Blockchain Currency Extended Reading

Blockchain Application:

Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

For example, Visa launched Visa B2B Connect based on blockchain technology, which can provide institutions with a lower-cost, faster and safer cross-border payment method to process business-to-business transactions worldwide. .

Be aware that traditional cross-border payments require 3-5 days of waiting and a 1-3% transaction fee. Visa also launched the first Bitcoin debit card in conjunction with Coinbase, and Citibank is testing the cryptocurrency Citicoin on the blockchain.
