1. What is an exchange and what does it do?

What is an exchange and what does it do?
1. What is an exchange? An information platform for trading certain information and items, etc. requires a fixed location called an exchange. The exchange, with the help of the information platform, realizes the sharing of property rights information, off-site transactions, unified coordination, and balances the property rights trading market and various terms.
2. What should you pay attention to when developing an exchange? 1. Choose a safe and reliable company that meets your needs. 2. Open a company and set up a company bank account 3. Apply for or assist in digital asset exchange licenses in operating areas as much as possible.
3. What is the use of blockchain exchanges? Building exchanges can meet the public’s need to make money, and is safe and stable. Blockchain exchanges are different from general trading platforms. Blockchain exchanges have the characteristics of distributed accounting, openness, and non-tampering and deletion. Suppose you keep accounts together, since everyone has written them down, but do they dare to change them? The answer is no, why don’t you dare to change it? Because it is very difficult and risky, unless everyone reaches an agreement and conspires to change the ledger, it will be too difficult. Why everyone keeps accounts at the same time? Because it ensures fairness, openness and disintermediation. The same is true for blockchain. Once the data is imported and the currency is listed on the exchange, it is very difficult and almost impossible to modify it.
4. How exchanges make money 1. Handling fees, this is the basic profit point. Usually both parties to the transaction need to pay a certain proportion of handling fees to the platform during the entire matching transaction process. At present, the main ratio is about one thousandth to five thousandths. '2. Coin listing fees. The role of investment banks is to provide currency issuance and underwriting services for digital currencies. The main method is for investors to use cash to conduct over-the-counter transactions to purchase "fiat currencies" (referring to circulating virtual currencies recognized by exchanges), and then Use fiat currency to purchase tokens of the issued currency. 3. Market makers. Compared with traditional stock exchanges, digital currency exchanges not only match transactions, but also play the role of market makers. The role of the market maker is to increase the liquidity of the market and thereby earn the price difference.

3. What is blockchain technology? What exactly is blockchain?

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-forgeable. Ledger.

Broadly speaking, blockchain technology uses block 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. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

Extended information:

[Blockchain core technology]

Blockchain mainly solves the trust and security issues of transactions, so it addresses this issue Four technological innovations:

1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they all Can participate in supervising the legality of transactions and can also jointly testify for them.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and of equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically, unless all nodes are destroyed, the accounts will not be lost, thus ensuring the security of the accounting data.

2.AsymmetricEncryption and authorization technology, transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner, thus ensuring data security and personal privacy. .

3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.

The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

5. How can newbies learn blockchain technology

It will be more systematic and efficient to follow the learning sequence:
(1) Establish an understanding of blockchain through more popular reading materials outline understanding;
(2) Understand the veteran: Bitcoin;
(3) Learn: Ethereum and EOS;
(4) Learn several projects that interest you, and seriously Thoroughly understand at least one project white paper;
(5) Expand learning through relevant media channels and continuously enrich your relevant knowledge.

In the eyes of many newcomers, blockchain is almost equal to Bitcoin, so it is necessary to first understand the overview of blockchain, just like taking a book, first look at the table of contents to know what it contains. Rather than turning to the first page and reading. After the first step of learning, I have a vague concept of Bitcoin, blockchain, exchanges and wallets. Hands-on practice is the best way to improve learning motivation and efficiency. It can also ask more practical questions in practice, and use questions to find answers, and the learning effect will be better. Therefore:

(1) Choose an exchange, such as: huobi.pro, okex.com, bigone, OTCBTC, etc., register an account. During this process, you need to pay attention to the use of Google Authenticator ;
(2) Buy a small amount, such as 0.03 Bitcoin, it is recommended to purchase through C2C OTC transactions and USDT trading pairs, and be familiar with the two purchase methods;
(3) Download and install the wallet, For example, Bitpie, pay attention to the safekeeping of mnemonic words;
(4) Transfer some Bitcoin from the exchange to the wallet.

After completing the above process, you will have a personal understanding of exchanges, wallets, private keys, OTC transactions, etc.

6. What are those working in the blockchain industry doing?

In recent years, blockchain-related concepts have become extremely popular, attracting many people to join the industry. What are these people who are really involved in the blockchain industry doing?

Usually what we call "blockchain industry" is a general term that includes three pillar industries that are interrelated and independently formed: currency circle, mining circle, and chain circle. At this stage, the best "money" scene is the currency circle, followed by the mining circle, and finally the chain circle.

Currency Circle

Currency Circle mainly focuses on the issuance, payment, and securities of digital currency (also known as virtual currency, cryptocurrency).

The earliest and most successful digital currency is Bitcoin (BTC). The Bitcoin white paper and software released by the still anonymous tycoon Satoshi Nakamoto in 2008~2009 marked the After the birth of Bitcoin, there are three main ways to issue digital currencies: forks, self-research, and tokens:

1. Among common currencies, BCH, LTC, DCR, and DASH , ZEC, etc. all came from forking BTC, mainly because they have some different propositions in terms of performance, privacy, encryption algorithms, etc.

2. ETH, EOS, etc. are relatively successful self-research projects. They are often not satisfied with issuing a new currency, but try to create a set of public projects that support the development of smart contracts and decentralized applications. platform.

3. Token issuance mainly relies on the capabilities of the aforementioned public platforms to issue new currencies in a very fast and easy way. These new currencies usually have some innovations at the business level. Or integration; Token has opened the door to a new world of digital currency issuance. Project crowdfunding (I-C-O), stable coins (USDT, etc.), platform coins, I-E-O, etc. are taking turns. It can be said that a hundred flowers are blooming and a mixture of good and bad.

Payment is the basic function of currency. In order to make digital currency faster and more convenient for transactions and circulation, many excellent products have been born, such as online or offline wallets that support many currencies, and peer-to-peer support. Or a settlement system for guaranteed transactions, a platform that supports the mutual exchange of digital currencies and legal currencies, etc.

The emergence of exchanges has given digital currencies strong securities attributes. Common exchanges usually support OTC (C2C) transactions, currency-to-crypto transactions, contract transactions and other functions to provide investors with 7x24 hours real-time online digital currency trading service. There are more investors participating in transactions, and investment services such as quantification, funds, lending, etc. have also been derived. Along with several rounds of bull markets, digital currency has been recognized, accepted and participated in investment by more and more people, and the securities function has developed much more powerfully than the payment function.

Mining Circle

With the development of technology and intensified competition, mining machines, mining pools, mining pools and cloud computing power services integrating the first three have become the core of the mining circle. Main business models.

In a popular senseAs understood above, mining is the process of generating new digital currencies through computers. Early digital currencies, especially Bitcoin, which has the largest market capitalization, usually used a proof-of-work (POW) mechanism to ensure the normal operation of the decentralized network and give participants digital currency rewards. As the value of digital currencies increases, competition in mining continues to intensify, and the computing power required to generate new coins is also constantly and significantly increasing: the earliest Bitcoins can be mined through the CPU of a personal computer, and later the computing power is stronger The GPU replaced the CPU, and in the future, dedicated mining machines, especially ASIC (Application Specific Integrated Circuit) mining machines, became the protagonist. The most important thing in developing ASIC mining machines is the development of dedicated high-performance chips, which represent the most cutting-edge technical capabilities; the second is the stability and energy efficiency ratio of the mining machines. The production of mining machines is usually through foundries, but strong supply chain, logistics management, marketing promotion, after-sales service and other capabilities are also essential.

A mine is a place where mining machines are deployed centrally. The ideal mine is built according to data center standards, but it is almost impossible to achieve it due to cost considerations. The most basic mine construction requires cheap and stable power supply, safe and spacious site, professional operation and maintenance team and other conditions. It also needs to be equipped with rack cabinets, temperature adjustment, noise isolation and other facilities. As the most important resource, cheap and stable electricity is usually owned by a few people (companies). They usually resell resources or build mines for self-operated mining and provide mining machine hosting services.

The emergence of mining pools is also due to the increasing difficulty of mining. Even if you have a state-of-the-art ASIC mining machine, the probability of directly mining coins is very low. Mining pools can unite many mining machines to form a huge computing power pool, increasing the probability of obtaining mining rewards. The main principle is to split the same mining task and send it to the mining machine connected to the mining pool, and receive and verify the calculation results submitted by the mining machine. If it meets the mining requirements, it will be submitted to the chain to obtain rewards. Different mines will also be counted. The computing power of the machine is distributed according to the computing power.

Because of the professionalism and high entry threshold of mining machines, mining pools, and mining pools, only larger and well-funded teams and institutions can participate in mining. Cloud computing power has passed Integrating high-quality resources such as mining machines, mines, and mining pools can directly deliver computing power of a specified size, and package it into a simple and easy-to-use mining service for ordinary users to purchase, which greatly reduces the funds and time for ordinary users to participate in mining. , resource and energy costs.

Chain Circle

Blockchain was born out of the underlying implementation of Bitcoin. In a narrow sense, blockchain is a way to connect data blocks in sequence in chronological order. A chained data structure composed of , is a technology that uses cryptography to ensure a decentralized ledger that cannot be tampered with or forged.

Blockchain is the carrier technology of digital currency. At the same time, after more than ten years of development, people have gradually realized that blockchainThe advantages and characteristics of technology can be applied to a wider field, so some people are devoted to the research, development and promotion of blockchain technology. There are three main parts: chain building, DAPP development, and blockchain+.

The popularity of blockchain technology has led to the development of many blockchains. The carrier chains of digital currencies such as BTC, BCH, ETH, EOS, etc. are usually released to the public network and developed by the open source community. A blockchain that is maintained and can be used by anyone can be called a public chain. Application-oriented chains led by commercial companies such as FaceBook, Internet, and Tencent are developed and deployed on intranets and are often called private chains.

DAPP refers to decentralized applications developed on the blockchain through smart contracts and other technologies. Most of them are applications for ordinary users on the public chain, such as electronic pets, gambling games, and decentralized applications. Exchanges, light games, etc. Blockchain+ is more of a commercial application developed by commercial companies based on private chains combined with a certain business field, such as points system, copyright certification, decentralized storage, bank securities, etc.

With the development of blockchain technology, I believe that more and more chains and excellent chain-based applications will be born.

1. Blockchain:
What is blockchain? 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.
Blockchain is a new application of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.Use patterns. 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 The data block contains information about a batch of Bitcoin network transactions and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
The original English version of the Bitcoin white paper does not actually 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.

2. Blockchain Types
Public Blockchain
Public Blockchain means: any individual or group in the world can send transactions, and the transactions can obtain the validity of the blockchain Confirmed that 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. .
United (Industry) Blockchain
Industry Blockchain: Multiple pre-selected nodes are designated within a certain group as bookkeepers, and the generation of each block is jointly decided by all pre-selected nodes (pre-selected nodes participate Consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (essentially still managed accounting, but become distributed accounting, how many pre-selected nodes, how to determine the accountant of each block to become the The main risk point of the blockchain), anyone else can conduct limited queries through the open API of the blockchain.
Private Blockchain
Private Blockchain: Only uses the general ledger technology of the blockchain for accounting. It can be a company or an individual, with exclusive write permission to the blockchain. This chain It is not much different from other distributed storage solutions. Traditional finance is trying to experiment with private blockchains, while applications of public blockchains such as Bitcoin have been industrialized, and application products of private blockchains are still being explored.
