How long does blockchain exchange transfer arrive
(1) introction to price limit trading mode:
price limit buying / selling refers to that the user sets the price and quantity of a buying / selling currency to generate an order. The system will automatically match the buying and selling orders in the market. Once the price set by the user is reached, the transaction will be automatically executed according to the price priority time priority
(2) introction to market price transaction mode:
market price purchase refers to that the user sets a total amount and generates a commission order, from the beginning of selling to the completion of the total amount transaction. Selling at market price means that the user sets the total number of currencies to be sold, generates a commission document, and matches it from the beginning of buying to the completion of the total number of currencies transaction
(3) introction to currency transaction mode:
currency transaction is mainly aimed at the transaction between virtual digital assets and virtual digital assets, in which one currency is used as the pricing unit to purchase other currencies, and the currency transaction rule is also to complete matching transaction according to price priority and time priority< (4) introction of C2C transaction mode:
both parties of the transaction release the transaction information of buying or selling currency on the C2C transaction platform according to the demand. The buyer and the seller complete the transaction offline according to the agreed payment method, and the platform, as an intermediary, charges a certain proportion of the handling fee from each successful transaction< (5) introction to OTC OTC trading mode:
it is a set of platform for offline purchase of digital currency independent of the exchange. Businesses can publish purchase / sale advertisements on the platform, and purchase / sale users can purchase / sell through offline transfer. After the transfer, the platform will transfer the frozen digital currency to the buyer, The technical construction problems of the exchange can be found on the Internet
(6) introction to trading mining mode:
the exchange platform returns a certain proportion of the commission income to the platform users, and the platform coin is returned. According to the principle of distribution proportion, the exchange platform takes a certain proportion as the mining reward. Mining refers to trading on the platform to graally unlock the platform coin until all the platform coins are fed back. This kind of play has a strong attraction to attract users< (7) introction to futures / contract trading mode:
futures contract is an agreement that the buyer agrees to receive certain assets at a specific price after a specified period of time, and the Seller agrees to deliver certain assets at a specific price after a specified period of time. The price that both parties agree to use in future trading is called futures price. The designated r period in which both parties have to trade in the future is called the settlement date or delivery date. The assets agreed to be exchanged by both parties are called "subject matter"< (8) introction to the trading mode of perpetual contract:
perpetual contract is a new and unique contract. The goal of the contract is to allow high leverage to the market conditions of the spot market. The contract will not be delivered and can follow the reference price index through various mechanisms. The contract evolved from the traditional futures contract, but the perpetual contract has more obvious advantages and greater risks than the traditional futures contract, supporting long short two-way trading, opening a 100 times leverage, permanent position, premium and so on.
the number of nodes of LBTC is 101. Compared with 21 or 51 nodes, the coin holder can vote for 51 nodes at most once in the wallet of LBTC, which further reces the risk of centralization; LBTC can output blocks stably in 3 seconds, and the block size of 2m ensures that LBTC is 400 times more efficient than bitcoin, and the transaction speed can reach more than 2000 transactions per second; The most important difference between LBTC and other projects is that LBTC's dpos mechanism has the rule of irreversible block. When the number of block agents reaches 90% or more in one round, or when the number of block agents exceeds 70%, the first block in the previous round can be considered as irreversible, so as to prevent bifurcation.
Let's suppose villagers Lao Wang and Xiao Li. Lao Wang borrowed some money from Xiao Li, who wrote it in an IOU signed by both parties. A few days later, Lao Wang denied the existence of borrowing money and claimed that Xiao Li forged the paper. Xiao Li can't argue because he finds it difficult to prove that Lao Wang actually owes him money
in this example, Lao Wang and Xiao Li are two nodes
now assuming the same scenario, there are many pairs of people trading with each other in the village. The only evidence for each pair is the IOU. If one party fails, it will be difficult to do so. Seeing this scene, the village head came up with a solution. He suggested using a common notebook for the whole village to record all the transactions. Due to the high prestige of the village head, the villagers unanimously decided to let the village head keep this important transaction book. Each transaction, the villagers go to the village head's home, let the village head witness and record, each transaction is written into a notebook, and then safely saved. That notebook can be called a database
because this notebook is very important, the village head locked it in the safe. However, there are always some problems. Sometimes, the village head will accidentally sprinkle ink on the paper, making some transaction records illegible. This is called a single point of failure. The thief knows that there is an important notebook in the safe of the village head's house. He tries his best to steal it. This is called hacking
until one day, the village head's son owed others a lot of money, so the village head secretly deleted his son's debt entry. In this way, the village head's son "does not owe money."
when the villagers knew this, they began to question the fairness and authority of the village head. So some people put forward a new idea:
abolish the power of the village head, which is called decentralization. Let all villagers keep a notebook, and the transaction records are copied and distributed, which is called distributed database. Therefore, if there are n people in the village, there are n notebooks, that is, n nodes. Every time there is a trade between any two people, all the people in the village get together and record it in their notebooks. And no one can cover the sky. This is called decentralization
they also decided that they would never delete the mentioned transactions from their notebooks, which is irreversible. For example, Lao Wang borrowed a sum of money from Xiao Li before, but in the twinkling of an eye, he wants to return the money. Then the transaction book will not delete the previous borrowing record, but write a new repayment record, so there are two records
next, let's try to break this rule. What if we bribe Lao Wang to change his notebook? It's not feasible, because the next time the villagers meet, they find that Lao Wang's notebook is different from everyone else's, so the villagers notice that Lao Wang may be engaged in an indescribable transaction, and decide to abolish Lao Wang's transaction record and kick Lao Wang out of the organization
What if you try to bribe all the villagers? It's too expensive
the characteristic of this model is that greedy people need to pay a lot to attack the rules. He will find it more profitable to follow the rules
a smart child in the village suggested that each transaction data be called "block" and linked into a "chain" in chronological order, which is called blockchain
for example: microcomputer Z_ If the clock frequency of 80cpu is f = 2.5MHz, its clock cycle T = 1 / F = 1 / 2.5MHz = 400 nanoseconds (t is the basic beat of computer operation), and its shortest instruction execution time is 4T = 4 × If 400 ns = 1.6 ns, the operation speed is:
V = 1 / 4T = 1 / 1.6 × 10-6 seconds = 0.625 × 106 times / S = 625000 times / s
another example: Z_ If the clock frequency of 80A is f = 4MHz, the clock cycle T = 1 / F = 1 / 4 × 106hz = 0.25 microseconds
the shortest instruction execution time is 4T = 4 × 25 μ s = 1 μ s
then the operation speed is: v = 1 / 1 microsecond = 1 million times / second
computing speed is an important index of computer performance
commonly referred to as computer operation speed (average operation speed), the abbreviation of average execution speed of single word fixed-point instructions MIPS (million instructions per second), the number of million machine language instructions processed per second
this is a measure of CPU speed
for example, an Intel 80386 computer can process 3 to 5 million machine language instructions per second, that is to say, 80386 is a CPU with 3 to 5 MIPs
MIPS is only a measure of CPU performance
refers to the number of instructions that can be executed per second, which is generally described as "million instructions per second"
microcomputer generally uses dominant frequency to describe the operation speed. The higher the dominant frequency is, the faster the operation speed is
the CPU frequency of a computer, which generally means the main frequency of the CPU, is regarded as the engine of a car
computing speed is equivalent to the performance of this computer, which is regarded as an indicator of how fast a car can run
how fast a car can run has something to do with the road, tires, frame, etc
computing speed is the result of a multi unit cooperation, which is related to cache, data width, instruction structure, etc.
computer running speed, architecture and dominant frequency. The better the architecture optimization, the higher the dominant frequency, the better the performance
the main frequency is limited by architecture, technology and materials
the relationship between them is quite complicated. For example, the dominant frequency of Ben 4 easily exceeds 3GHz and fails to impact 4GHz. However, the highest frequency of Ben 4 is also a slag in front of the next generation of core, which is less than 2GHz. The actual running speed is far from satisfactory
therefore, the main frequency of CPU is not directly related to the speed, but it is basically positively related, that is, the larger the main frequency is, the faster the operation speed is, because the main frequency is the number of beats per second of the clock, just like the heart. The CPU will work only when it is at a high level, so to some extent, the larger the main frequency is, the faster the operation speed is.

bitcoin is a kind of virtual currency, and its quantity is very scarce. We can invest by buying bitcoin or by buying the rise and fall of the last three digits of bitcoin this guy is Xiao Liu. He is still in school, and the school has winter vacation. After the holiday, he went home and would brush short videos at home when he was free. One day when he was writing a short video, he saw something about bitcoin investment and felt very excited
I think parents should ecate their children correctly. If children want to learn to invest, parents can teach them hand in hand and give them some small money to try water. When they lose money, they will find that investing is not as easy as they think. At this time, parents can give their children some books so that they can systematically learn to invest, or let them do their study well first. If their study reaches any ranking, they will give them appropriate investment again. Of course, they must let them learn to invest before this investment. And the money lost can be regarded as the tuition fees for children
conclusion: within 0-30 minutes, XRP is translated into reborn coin in Chinese, which is an abbreviation of blockchain project token with high consensus in developed countries. It has been widely used in banks of major cross-border payment systems. The overall market value is in the top five, which can be obtained from mytoken, non trumpet, coinmarketcap and other well-known query websites
it may be incorrect, but please don't insult yourself by answering the wrong questions. The network should also be controlled.
