Translation of blockchain terms
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
1. Blockchain is a distributed database (system) placed in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data
the system with the above three properties is blockchain.
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.
blockchain is a decentralized distributed ledger database . The advantage of this distributed ledger is that buyers and sellers can trade directly without any intermediary. Everyone has a backup, even if you lose this, it will not be affected

extended data:
blockchain application field
1, financial field
blockchain has potential huge application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment
2. The Internet of things and logistics
blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain
3. The data stored on the public welfare field
blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
4. In the field of insurance
in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized
