Virtual currency opening
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

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

Whether long or short, placing an order is called & quot; Opening & quot;. Can also be understood as in the transaction, whether it is to buy or sell, all new positions are called open positions
Before the maturity of physical delivery or cash delivery, investors can voluntarily decide to buy or sell futures contracts according to market conditions and personal wishesIf an investor (long or short) does not perform the reverse operation (sell or buy) with the same delivery month and quantity and holds a futures contract, it is called "position". In the operation of gold and other commodity futures, whether buying or selling, all new positions are called Jiancang. After the operator builds a position, he holds a position in his hand, which is called position

extended data:
open position, open position and close position are all terms in futures trading. The characteristics of futures trading are as follows:
1, contract standardization
futures trading is carried out through trading futures contracts, while futures contracts are standardized. Standardization of futures contract means that all terms of futures contract are prescribed by futures exchange in advance except price, which has the characteristics of standardization. The standardization of futures contracts brings great convenience to futures trading. The two sides of the transaction do not need to negotiate the specific terms of the transaction, so as to save transaction time and rece transaction disputes
2. Trading centralization
futures trading must be carried out in the futures exchange. The futures exchange implements the membership system, and only members can enter the market for trading. If those customers who are outside the market want to participate in the futures trading, they can only entrust the futures brokerage company to trade. Therefore, the futures market is a highly organized market, and the implementation of a strict management system, the final completion of futures trading in the futures exchange
Two way trading and hedging mechanism, that is, futures traders can either buy futures contracts as the beginning of Futures Trading (called buying Jiancang), or sell futures contracts as the beginning of Trading (called selling Jiancang), which is commonly known as "short selling"hedging mechanism is also related to the characteristics of two-way trading. In most futures trading, it is not through physical delivery when the contract expires to fulfill the contract, but through transactions in the opposite direction of the transaction when the position is established to release the responsibility of performance
specifically speaking, after buying a position, the performance responsibility can be relieved by selling the same contract, and after selling a position, the performance responsibility can be relieved by buying the same contract
the characteristics of two-way trading and hedging mechanism of futures trading attract a large number of futures speculators to participate in the trading, because in the futures market, speculators have double profit opportunities. When the futures price rises, they can buy low and sell high to make profits. When the price falls, they can sell high and buy low to make profits. Moreover, speculators can avoid the trouble of physical delivery through hedging mechanism, The participation of speculators greatly increases the liquidity of futures market
In other words, traders only need to pay a small amount of margin, which is generally 5% - 10% of the contract value, to complete several times or even dozens of times of the contract transaction. This feature of futures transaction has attracted a large number of speculators to participate in futures transactionfutures trading has the characteristics that it can make a large amount of investment with a small amount of funds, which is vividly called "leverage mechanism". The leverage mechanism of futures trading makes futures trading have the characteristics of high yield and high risk
