How long does it take to confirm blockchain transfer

1. This is not a rigid rule. It has nothing to do with blockchain. There is a relationship between the algorithm of this currency. The confirmation method of each currency is different, so this is not a rigid rule
the confirmation times of bitcoin are different from that of Ruitai coin, Laite coin and doggy coin.

2. In recent years, e to the waste of resources, unstable block output and computing power attack of pow, although POW is recognized as the most widely used and secure consensus mechanism, there is still a great risk of being attacked for the block chain with insufficient computing power in the whole network. More and more consensus mechanisms are proposed to be used in blockchain projects for trial and experiment. Dpos is one of the mainstream consensus mechanisms, and LBTC has adopted this mechanism. Dpos ensures that the voting right is in the hands of the coin holder, so the coin holder will be able to choose whether to pass the motion by voting, so as to determine the development direction of the project. At the same time, it also means that the development direction of the project depends on the hands of the people who care about the project itself, and the power of wisdom will promote the better development of the project. At the same time, the advantages of dpos mechanism are that there is no computing power attack, strictly abide by the time block and save resources
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.

3. Contract transaction refers to an agreement between the buyer and the seller to accept a certain amount of certain assets at a specified price at a certain time in the future. The trading object of contract trading is the standardized contract formulated by the exchange. The exchange specifies the standardized information such as the commodity type, trading time and quantity. The contract represents the rights and obligations of both parties
to put it simply, we should make an appointment to trade a certain amount of certain goods at a certain time and place in the future.

4. The following calculation methods can be used:
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.

5. Bank of China can conct foreign exchange trading. You can open an account at the branch

it's convenient to buy and sell on the phone and online

6. Transfer in daily life is essentially different from blockchain transfer, which makes the understanding of blockchain transfer state complicated

we will see such states as "waiting for confirmation", "confirming", "transaction failed", "successful", some of which belong to the unique state of blockchain transfer

bank transfer
there are two steps in daily life: payment and settlement

normally we all belong to "payment" through Alipay consumption and bank card transfer, which is essentially a record of information and a credit debt certificate. And this kind of certificate needs to be implemented, that is, liquidation. Its essence is the flow of funds

a common situation:

transfer 200 yuan from my CMB card to your ICBC card
there are two steps in this process:

when I successfully transfer 200 yuan to you, this step is "payment" for you and me, and its essence is information flow; For China Merchants Bank and instrial and Commercial Bank of China, it is to establish the relationship between creditor's rights and debts. It records a debt note: China Merchants Bank owes ICBC 200 yuan
then, the banks regularly implement their complicated creditor's rights relationship in the central bank's clearing system (the first step of "CMB owes ICBC 200 yuan" is one of the inextricable links). At this time, it is through "clearing" that information flows into real capital flow
for us, once the transfer button is confirmed in the first step, you can rest assured and I can rest assured. But actually, it's only the first step. In the future, the real time-consuming operation will be hidden in the cycle operation of the whole financial infrastructure and system. They are not common people, but the cornerstone of our convenient financial life< br />

blockchain transfer
does it have payment and clearing? This concept actually does not exist here. Blockchain transfer integrates these two steps, and each transfer on the chain records the real capital flow

as a public account book, blockchain is open, transparent and tamperable

therefore, the transfer on it is in a more complicated state. This account book can not be wrong and must be recorded carefully

so we can see these states: "waiting for confirmation", "confirming", "transaction failure" and "success"

"waiting for confirmation": waiting for the miner to confirm the transfer information and pack it into the block

"confirming": one block confirmation is not secure enough and needs more confirmation. In this way, we can understand why Ethereum transfer needs 12 block confirmations to be considered successful

"transaction failure": if the fee you give to the miner is not enough for the miner to confirm the transfer information, it will fail (or it may be caused by other reasons)

"success": at this time, your transfer record is on the blockchain ledger, which can not be tampered with and can be checked.

7. What is the longest chain? Why the right blockchain
according to the white paper of bitcoin, nodes always think that the longest chain is the right blockchain and will continue to extend on it. All miners are mining on the longest chain, which is concive to the uniqueness of blockchain ledger. If the bitcoin transaction transferred to you is not recorded on the longest chain, you may face property losses
what is the "longest blockchain"? Because the miners all over the world are mining at the same time, it is possible that two miners can work out the correct answer at the same time, then the blockchain will form a fork, and the remaining miners may continue to mine on any fork, extending the blockchain
therefore, we usually require that after the bitcoin transfer is packaged, we need to go through the confirmation of six blocks to ensure that the miners will not go back to the other branch to excavate, then the real transfer is successful.

8. Wait for the blockchain confirmation to be completed, and then it will arrive at the account
if the blockchain has been confirmed but has not arrived in the account, please contact the receiving platform to enter the account for you.

9. XRP uses a confirmation in all major exchanges to get to the account. The premise is that the address and label should be filled in correctly. A confirmation in XRP network usually takes 1-10 minutes to get to the account, sometimes it takes half an hour. In this case, the exchange or the sender and receiver spend more time in the security verification accounting system
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.
