Blockchain industry terms
IBM and giant automobile manufacturers are trying to use blockchain technology to solve instry pain points. In addition, there are "declining" enterprises such as Kodak of Japan, hoping to fight a "turnaround battle" through blockchain
What does these phenomena show? This shows that the technology of block chain has great commercial value. Everyone hopes to cultivate a new world on this unknown land. So, with the development of blockchain technology this year, it has not only been a simple underlying technology, but also formed a complete ecosystem. Now let's talk with you from two aspects of "coin circle" and "chain circle": what is the ecosystem of blockchain, and let's understand the whole picture of blockchain instry
the first section of the coin circle
in the coin circle, there are always several terms: project party, exchange, media, mining machinery manufacturer. Next, let's take a detailed inventory of what's going on
first, the project side of the coin circle can be understood as follows: all those who issue tokens are the project side. Attention, it's a coin ring. There are also some project parties that don't issue money, such as Alibaba, Tencent and Netease, which are also doing blockchain projects. They don't issue money and only focus on technology. Then these project parties that don't issue money mainly focus on the role of blockchain in data security and supply chain, which we will talk about later
let's return to the topic of coin circle project parties. For example, yilaiyun and BoChang, which are more controversial recently, are the project parties of coin circle, as well as blockchain games, which are more popular recently. They also belong to coin circle project parties
one of the subversive aspects of the coin circle project is the combination of the project and the token, which directly replaces the equity with the token, and the token can be directly circulated. This is a very revolutionary point, so that many initial projects can be more convenient for financing. After financing, the feedback token can be circulated on the digital currency trading platform, and the investors can also exit very well
this "financing investment" approach seems to be another way to realize the listing and trading of equity in disguised form
therefore, it is such a mode that makes the project side of the coin circle the nearest place to the money. They can easily circle the money, and of course they can't resist the temptation, or they have been planning for a long time and run away after circling the money. The detailed process of token issuing by the project side is generally as follows:
the first step is to build a token system, which is similar to an app application. This is not very complicated, because Ethereum is open source, similar to Android Apple system, on which developers can develop specific applications
the second step is to write a white paper, which is similar to the business plan. The white paper is similar to the business plan, mainly including the team situation, technical situation and other information of the project
the third step is to find someone to do endorsement, and find some influential instry bigwigs to promote
the fourth step is to promote marketing, find some blockchain media to push soft articles and pull cooperation, which we will mention below
the fifth step is to find financing
Step 6: go to the stock exchange, and the token begins to spread widely
Second, the exchange
with the project side, let's talk about the exchange. If the project side is a procer, then the things they proce have to be sold and traded, right? The exchange is a trading place for the token of the project party. If the token of the project side is similar to the stock, then the exchange of the currency circle is similar to the secondary market of the stock market. However, the exchange of the currency circle has more power. It has the right to audit the currency, and can decide whether to put the currency in or out
of course, if the project party wants to pay the exchange a huge amount of money charging fees, the investors who trade in the exchange also need to pay the handling fee or withdrawal fee, and the rules of the handling fee and withdrawal fee of each exchange are different. In fact, the currency fees, handling fees and cash withdrawal fees constitute the profit model of the currency circle exchange. Of course, in addition to these three profit models, the profit model of the exchange includes the "market maker" business to earn the price difference, that is, the exchange creates liquidity through continuous trading, acts as a market maker and earns the price difference at the same time
at present, e to the increasingly fierce competition in the instry, there will be less and less currency fees and handling charges, or even no need, so the proportion of conventional profits will be less and less, which leads to the emergence of other profit models, such as platform currency and leverage handling charges. Let's talk about platform currency first. Platform currency is the currency issued by the exchange: okb and coin an belong to platform currency. These platform currencies issued by the exchange can be exchanged for BTC and eth. At the same time, the appreciation of platform currency's own value can lay a solid material foundation for the development of the exchange. For users, holding platform currency can enjoy the benefits of commission discount, platform dividend, special activities of the exchange, etc, This is platform currency. Leverage service charge refers to the currency financing function on the platform, which supports leveraged transactions and charges a certain proportion of service charge to currency financing users
all of the above are actually ecosystems constructed through the exchange's own resource output. Now, the exchange is still actively planning the whole instry to obtain income, such as the establishment of capital, mine pool, wallet, incubator, Engineering Institute, fund and other ways. We believe that if the exchange wants to develop for a long time, it must lay out the whole instry chain, find new breakout points of the instry, and build a complete ecosystem. Therefore, the proportion of strategic profits should be increased
3. Blockchain media
in the past two years when blockchain is hot, there are not only a lot of project parties, but also media. At present, there are about 200 well-known blockchain media. The content on the blockchain media platform is about the following points: policy, hacker, exchange, boss and project party. In addition to words, the operation mode of blockchain media also includes community activities, such as inviting "big guys" to share in the group, so as to achieve a precipitation of high-quality content and earn some traffic at the same time
Why do we have to mention blockchain media? It's because there are some differences between blockchain media and the media in our impression. What's the difference? The difference is that there are some interest relationships between blockchain media and the above mentioned project parties and exchanges. We just said that the project side is like a "procer" and the exchange is like a "sales market". Then, the role of the media is like "advertising platform & quot;. If the project wants to sell well, it needs publicity and advertising, then blockchain media plays such a role. Therefore, the investors of some blockchain media are the project side and the exchange
recently, there has been a bear market. Many blockchain media have laid off employees on a large scale. The reason is nothing more than the shortage of projects and funds. Therefore, it is far from enough for blockchain media to rely solely on the investment of the project side, the exchange and the advertising revenue. When the bear market comes and the project side and the exchange are affected, then the media is bound to face a very cruel winter. As a result, many blockchain media are also doing token issuing by project parties (the most typical are content communities such as coin and coin car, which belong to a media platform and are also doing token issuing by project parties), or some blockchain media are doing business such as wallet selling, mining machine renting and computing power
however, we believe that blockchain media, as the media, still play the role of guiding public opinion. Therefore, we should return to the essence and be a place to deliver instry value information, rather than a place to pile up advertisements. Therefore, blockchain media should keep up with the development of technology to realize its own survival and development. Relying on the advantages of blockchain technology and based on the consensus mechanism in the token system, it can realize the reasonable distribution of the interests of the media instry. In this regard, it may have a certain imagination< Fourth, mining machine manufacturers
in the final analysis, bitcoin mining is the competition of computing power. The stronger the computing power, the greater the probability of bitcoin mining. Therefore, in the business system of the whole coin circle, mining machinery manufacturers are a very important existence. We can see from one data: in the blockchain instry of Hurun 100 rich list in 2018, the richest person is Mr. Zhan ketuan, a partner of bitcontinental, a miner. In addition, according to the prospectus, bitcoin's net profit in the first half of the year was US $743 million, an increase of nearly eight times over the same period last year. Bitcoin once occupied more than 70% of the global market share of mining machinery, becoming the leader in the mining machinery instry. Not only mining machinery, bitmainland still occupies a near monopoly position in the mining pool (that is, a mode of cooperative mining): at present, the computing power of the top six mining pools in the world accounts for 79.2%
after the invention of China's first bitcoin miner, Jianan Yun, another miner chip research company, began to engage in the research of chips in the field of blockchain and artificial intelligence. In just a few years, it has also become an internationally famous chip enterprise
in fact, as early as 2012, the United States announced that it was going to sell a butterfly miner, but many people later thought it was a scam, because it took several years for the butterfly miner to go on sale, which also made the R & D of mining machines in other countries become very scared, and they were all scrambling for time, in a sense, Butterfly mining machine is also driving the prosperity of mining machine instry. So, in 2013, the mining machine has entered a season of contention, and a large number of ASIC mining machines have been put forward: or announced research and development, or announced pre-sale, or in the form of spot: cat roasting mining machine, pigeon mining machine, TMR mining machine, biter mining machine, Rand mining Bureau, little bee mining machine, Avalon original factory and various OEM, garden mining machine, Smart mining machine and so on... Maybe you haven't heard of these mining machines, because they are basically dead. Bitcontinental, Jianan Yun and Yibang have become mining machine giants< However, as a derivative instry under the prosperity of cryptocurrency market, the price of mining machinery is closely related to the cryptocurrency Market: in the bull market, the supply of mining machinery often falls short of demand, and it is common for miners to buy Mining machinery from "scalpers" at several times high prices. At this time, mining machinery manufacturers enter the dividend period. However, in a bear market, mining machinery manufacturers will also be adversely affected. As miners' enthusiasm for mining declines, some manufacturers have to rece the price of mining machinery to recover costs. For example, when bitcoin plummeted in March this year, a certain model of mining machine sold by Huaqiangbei was on sale at a price of 5000 yuan, and the price dropped from about 19000 yuan to
14000 yuan
[summary]
at this point, we can find that whether it is the project party, the exchange, the media, or the mining machinery, it can be said that it is a kind of "one-stop"
blockchain is a digital account book that can be jointly bookkept, and will record all transactions that have occurred and have been unanimously recognized by the system it's the same as the whole family. You're bookkeeping, and your father and mother are also bookkeeping. They can see the general ledger, but the saved information can't be tampered with any more
In 2008, Nakamoto first proposed the concept of blockchain subsequently, blockchain has become the core component of electronic currency bitcoin, which serves as the public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independentlyextended data:
type of blockchain
1, public blockchain
any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain. There is only one blockchain corresponding to this currency in the world
2, Alliance (instry) blockchain
instry blockchain: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction, However, regardless of the bookkeeping process (in essence, it is still managed bookkeeping, only distributed bookkeeping, how many preselected nodes, and how to determine the bookkeeper of each block to become the main risk point of the blockchain), anyone else can conct limited query through the open API of the blockchain
3, private blockchain
only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and enjoys the write permission of the blockchain. This blockchain is not very different from other distributed storage schemes
Blockchain blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and cryptocurrency algorithm. Is a shared distributed ledger in which transactions are permanently recorded through additional blocks
2, block - block
in the bitcoin network, data will be permanently recorded in the form of files, which we call blocks. A block is a set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks
3. Node -- a of the ledger operated by the participants of the blockchain network
Decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials. The influence between nodes will form nonlinear causality through the network5. Consensus mechanism
consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus
6. POW -- proof of work refers to how much money you get depends on the amount of work you contribute to mining. The better the performance of the computer, the more money you will be given
In POS mode, your "mining" income is directly proportional to your currency age, and has nothing to do with the computing performance of the computer8. Smart contract
smart contract is a kind of computer protocol which aims to spread, verify or execute the contract in an information way. Smart contracts allow trusted transactions without a third party, which are traceable and irreversible
9, time stamp
time stamp refers to the string or encoding information used to identify the recorded time and date. The international standard is ISO 8601
Turing completion refers to the ability of a machine to perform calculations that any other programmable computer can perform DAPP decentralized application is an open source application that runs automatically, stores its data on the blockchain, motivates it in the form of cryptocurrency token, and operates with protocols showing valuable proof Dao, a decentralized autonomous organization, can be regarded as a company that operates without any human intervention and gives all forms of control to a set of unbreakable business rules13. Privatekey - private key
a private key is a string of data that allows you to access a token in a specific wallet. As cryptocurrency, they are hidden except for the owner of the address
14. Publickey -- public key
is paired with private key. The public key can calculate the address of the currency, so it can be used as a certificate to own the address of the currency
15, miner
try to create a block and add it to the computing device or software on the blockchain. In a blockchain network, when a new effective block is created, the system will automatically give the block creator (miner) a certain number of tokens as a reward
16. The mine pool is a fully automatic mining platform, which enables mining machines to contribute their computing power to mine together to create blocks, obtain block rewards, and distribute profits according to the proportion of computing power contribution (that is, mining machines access the mine pool - provide computing power - obtain income)
17, public chain
fully open blockchain, refers to anyone can read, anyone can send transactions and transactions can be effectively confirmed, people all over the world can participate in system maintenance, anyone can read and write data through transactions or mining
18. Private chain
write permission is only for the blockchain of a certain organization or a specific few objects. Read permission can be open to the outside world or restricted to any extent
19, alliance chain
consensus mechanism is a blockchain jointly controlled by several designated institutions
20, side chain
wedged side chains technology, which will realize the transfer of bitcoin and other digital assets between multiple blockchains, which means that users can access the new cryptocurrency system when they use their existing assets
21, cross chain technology
cross chain technology can be understood as a bridge connecting the blockchains, and its main application is to realize atom transaction, asset conversion, information exchange within the blockchain, or solve Oracle problems among the blockchains
22. The hard fork
blockchain has permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually the hard fork will occur
23, soft forking
when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, which will lead to temporary forking
24, hash -- hash value
generally translated as "hash", but also directly transliterated as "hash". In short, it is a function that compresses messages of any length to a message digest of a fixed length
25, main chain
the word "main chain" comes from the main network (, relative to the test network), that is, the officially online and independent blockchain network
for those who don't know the "jargon" in the currency circle, let's learn it as soon as possible:
1. What is legal currency legal currency is legal tender, which is issued by the state and the government. It is only guaranteed by the government credit, such as RMB, US dollar and so on 2. What is a token token, usually translated into token. Token is one of the important concepts in blockchain. Its more well-known name is "token". However, in the view of professional "chain circle" people, its more accurate translation is "token", which represents a proof of rights and interests on the blockchain, rather than currency token one is digital proof of rights and interests, which must be in the form of digital certificate of rights and interests, representing a right, an inherent and intrinsic value
3. What is warehouse building
the establishment of a position in a currency circle is also called opening a position, which refers to a trader's new purchase or sale of a certain amount of digital currency
What is Sohasuoha refers to investing all the principal
What is airdrop
airdrop is a very popular marketing method of cryptocurrency. In order to let potential investors and cryptocurrency enthusiasts get token related information, token teams often air drop tokens
6. What is lockup position locking generally refers to investors opening a new position opposite to their original position when the market moves in the opposite direction after the sale and purchase contract, which is also called lock, lock order, or even butterfly double flying doughnut candy is a kind of free digital currency issued to users when all kinds of digital currencies are just issued in ICO. It is a kind of momentum and publicity of the project itself by the issuers of virtual currency projects
breaking refers to falling below, and issuing refers to the issuing price of digital currency. Broken currency circle refers to the price of a digital currency falling below the issue price
What is private placementprivate placement is a way to invest in cryptocurrency projects, and it is also the best way for cryptocurrency project founders to raise funds for platform operation
What do you think of the K-line diagram
K-line chart is also called candle chart, Japanese line, yin-yang line, bar line, red and black line, etc., commonly referred to as "K-line". It is based on the opening price, the highest price, the lowest price and the closing price of each analysis cycle
What is hedging
General hedging refers to two transactions which are related to the market, opposite in direction, equal in quantity and balanced in profit and loss. In the futures contract market, buy the same number of positions with different directions. When the direction is determined, close out the positions in the opposite direction and keep the positive direction to make profits
What is the positionposition is a kind of market agreement, which promises the initial position of the sale and purchase contract, and the buyer is long and in the expected position; The selling contract is short and in the expected position
What are the advantagesgood news: refers to the news that the currency gets the attention of the mainstream media, or a breakthrough in the application of a technology, which is concive to stimulating the price rise
14. What is bad news
bad news: news that causes the price of bitcoin to fall, such as technical problems of bitcoin, central bank's crackdown, etc
What is reboundthe phenomenon of currency price rising e to rapid decline in the downward trend. The recovery is less than the decline
What is leverage
leverage trading, as the name suggests, is to use small amount of funds to invest several times the original amount, in order to obtain multiple returns or losses relative to the fluctuations of the investment object
currency circle: refers to the people who focus on currency speculation or even issue their own digital currency to raise funds. Generally speaking, blockchain project parties, exchanges and some blockchain media all belong to the currency circle
chain circle: refers to people who focus on the research and development, application or underlying protocol of blockchain. Without the technical support of the chain circle, the coin circle can not exist. In the future, the implementation of the blockchain scene will depend on the technology of the chain circle
Mining circle: refers to the "miners" who focus on "mining"< Second, several investment behaviors of blockchain
currency speculation: similar to stock speculation, refers to the behavior of repeatedly buying and selling digital currency through trading platform in order to obtain high income
Soha: it's a transliteration of show hand, originally a term used in gambling games. It's the act of withdrawing all available chips at one time. When it comes to blockchain investment, it refers to investing all of your available assets in digital currency in order to speculate in money, which has the meaning of "bet your fortune"
Buddhist holding of cryptocurrency: it refers to the behavior of not caring about the price trend of cryptocurrency after holding of cryptocurrency. No matter how much the asset price of cryptocurrency falls, it will not rece the holding of cryptocurrency in hand
3. Segmentation of blockchain investors
banker: refers to the investor with strong capital volume, strong relationship network and the most informed information, who can influence or determine the price trend of a certain currency to a large extent
large investors: investors with abundant capital, but not as strong capital and relationship network as makers
retail investors: refers to the small amount of funds, small amount of trading, and unorganized investors< Four, blockchain investment common phenomenon
leek: is an image of metaphor, leek growth ability and adaptability are very strong, can be one after another in a large range of breeding. It is compared to some retail investors who do not know the market situation. Most of them are easily influenced by the investment sentiment. They buy at a high price and sell at a low price. Some people will lose money, and after they leave the market, new forces will enter. Like leeks, they will cut one crop and grow another soon
cut leek: it means that the dealer buys at a low price, speculates at a high currency price, sells at a high price after the retail investors come in and make a profit, and then smashes the plate to a low position. In this way, the retail investors will suffer losses and the dealer will make a profit. The makers and the big investors keep repeating this routine, that is, "cutting leeks", while the retail investors keep entering, the makers repeat the routine of cutting leeks
cut back: refers to the sharp drop in the price of digital currency, which is very huge, falling to half of the previous highest price. For example, when I buy a currency, the highest price of this currency is $100. After a while, I fall to less than $50. It can be said that my currency has been cut off
meat cutting: it refers to the behavior of selling stop loss in time when the price of digital currency falls in order to prevent the continuous decline from causing greater losses, so as to prevent greater losses in the future
being held up: it means that I spend a high price to buy a currency. After a while, the currency falls, and I don't want to sell it and stop loss in time. Instead, I choose to wait to see if the price can rise again. The waiting process is "being held up". In this case, I can be said to be held up
unwinding: it means that the purchased digital assets graally rise back after a round of sharp decline, and the price rising back exceeds the price when I bought them. At this time, I will not lose money when I sell these digital assets. This is unwinding
airdrop candy: refers to the free distribution of a certain amount of digital currency to users in order to promote the blockchain project at the beginning of the project. These free digital currencies are called "candy" by users.
utility token is a utility token that acts as a right to use a specific service
examples of terminology usage
utility tokens are premised on the use of services
detailed description
you can settle the price of goods and meals instead of cash, and you can access it by having cloud storage. For utility tokens, there is no need to audit the classification of the report
public chain is a highly "public" blockchain, anyone can freely participate in the network
example of terminology usage
as an infrastructure project for mediating data exchange between blockchains, a mechanism for data exchange on public blockchains will be established
detailed description
in the blockchain used to record the transaction information of encrypted assets (virtual currency), this is a mechanism used by an unspecified number of participants to establish transaction information by consensus without a specific management entity. It is very safe to prevent forgery of transaction information, but it requires a lot of calculation, so its disadvantage is that it takes a long time to complete the transaction when there are many participants
7. Scalabilityscalability refers to the scalability of delayed transaction processing
examples of terminology usage
soaring gasoline prices highlight Ethereum's scalability issues
detailed description
e to the nature of blockchain and the limited amount of transaction data that can be written in a block, the processing is delayed. Remittances can take a long time, which can lead to higher transaction costs. Bitcoin is the first cryptocurrency born, which has been considered as a special problem, but efforts to solve this problem have been implemented, such as using other technologies such as lightning network and developing new blockchain
8. Gas costgas cost is the (Network) transaction cost on Ethereum blockchain
examples of terminology usage
this week, on the Ethereum blockchain, although there are a small amount of remittances, there are still many cases of high natural gas bills being paid
detailed description
the gas fee of user specified amount is the secondary reward. Eth, the virtual currency, is used for payment. Since the transaction with higher cost should be dealt with first, the gas cost may increase with the increase of transaction number
9. Liquidity mining (liquidity mining)considering the provision of liquidity (currency pair), liquidity mining is to grant governance token in addition to interest, so as to attract those who implement the rate of return balance
examples of terminology usage
detailed description
in liquidity mining, by storing specific assets in the liquidity pool and providing liquidity that traders can buy and sell, the swap fee at that time can be obtained as income. These liquidity mining originated from the largest decentralized exchange "uniswap", and many liquidity mining contracts were born, such as curve finance and balancer
10. Defi (distributed Finance)defi (decentralized Finance) refers to the financial services or systems that use blockchain and provide without a central administrator
examples of terminology usage
since June 2020, the market of defi has developed rapidly
specify the abbreviation of "decentralized finance". The financial services offered by defi include the issuance of stable coins, lending currency and cryptocurrency exchanges. Many platforms use Ethereum blockchain
11. POS (proof of equity)POS is a consensus algorithm, which allows you to approve and generate new block rights according to the percentage (equity) of your own virtual currency
According to vitalik buterin, co-founder of Ethereum, migrating eth's consensus algorithm from POW to POS will improve security and scalabilityspecify the abbreviation of
proof of interest. We can also consider the holding period of virtual currency. It was born as an alternative to the "proof of work (POW)" consensus algorithm, which requires high-performance computers to approve transactions and consumes a lot of energy. If approved, you can receive a new virtual currency as a reward
12. DappsDAPP is an application developed with open source blockchain
examples of terminology usage
Galaxy store, the largest Samsung Electronics app store in South Korea, has started to use Tron's blockchain to process dapps
detailed description
the abbreviation of "distributed application" is called "distributed application" in Japanese. One of the main features is that there is no centralized administrator. The most popular is Ethereum blockchain, which is developing applications such as games and decentralized exchange (DEX)
