How long does the blockchain network node confirm 15 times

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.

first, define the

blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain

Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network security

in the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent

In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high fees

3. Bitcoin network is a global P2P network, which is jointly maintained by all the nodes accessing the network (which can be understood as computers). On average, the global network (not a company or indivial) confirms the transaction every 10 minutes. Bitcoin network miner is to maintain the operation of bitcoin network, to confirm every transaction, can not contact directly< Br > take bitcoin as an example: e to the technical advantages of our platform, the bitcoin you receive will arrive at the account for transaction after one confirmation, and it will take six confirmation (i.e. one hour) before it can be fully arrived at the account and used by you for re payment or transfer out< Br > (Note: e to some special reasons, the confirmation time of indivial transactions may exceed the average time.)< Br > at present, all recharged currencies can be transferred to currency transaction or contract transaction after they have been confirmed by the platform, and the funds can be transferred to the legal currency trading area for sale after they have been fully confirmed.

4. 99% of them are deceiving. It's deceiving to say how much it will appreciate. It's just a technology, its application is valuable.

5. Depending on your basic level, if you have a certain technical foundation for development, it is relatively easy to learn
"chainman College" offers short weekend technical training courses for colleges with a certain programming foundation. You can investigate them and ask about your situation.

6. Jinwowo analysis: a node is actually a computer (server) connected to the blockchain. Any connected computer can access the blockchain, so there are countless nodes on the blockchain; However, the number of blocks on the blockchain is limited, that is, one block is generated every 10 minutes, and no new blocks will be added after reaching a certain number.

7. Don't be depressed, it must be conditional to get a fixed IP, and then set up your own network through this IP, it will become your biggest trouble, know how to change the IP of the router, the current use is Avalon's 220 mining machine. That's why laomaozi likes mining very much. Don't take it for granted that a meeting will be OK one day, even if water cooling is installed
when the mining machine starts to operate, you need to be extremely careful, register an account of a mining website, and mining is not as simple as you think, and then you need to register
3-1, the machine has problems again. You have to accept it
if it is possible to install water cooling, there should be a relatively cold environment
if you can pull the wire and the wiring board in the balcony, you need to think carefully first. In actual mining, you will obviously feel the importance of temperature for mining, and have the conditions to repair the chip capacitor in the process of water cooling installation! Need to understand the routing, can accept the noise - mining machine noise is very big, it is not suitable
please don't feel indifferent to the above points
if your home is warm, you will set up the network - not just plug in the Internet, but in the workshop. Don't be confused by interests. Hope it can help you? It can be installed conditionally
let's assume two scenarios, first understand these, and then decide whether to join the miners army? Give up if you can't, or sell it as a second-hand machine and download a multibit to store the bitcoin you get
congratulations? Is it possible to set up a network? Yes
at home
3,
in the company< br />1-1
is it warm in that room
I'm a miner. When I make a rumbling sound, there are some things that I can't solve and overcome. You can buy a miner to dig it up. But there's one that doesn't work. The miner's IP is fixed. I think the electricity charge is the whole province, not a big problem. I want to connect the miner to the network for electricity. For example, if you have the conditions to install water cooling, the installation process of water cooling is not as simple as the online tutorial seems. In the environment with low temperature - in addition to being able to power on and off for 24 hours, you have strong hands-on ability - the noise can be controlled to a certain extent by installing water cooling. As for how to dig, it's the simplest thing. It turns out that the mining machinery can't be connected to the Internet
first list the problems you have to face, then you need to figure out how to explain to your family or girlfriend
and if you work hard to move the mining machine to the company, I'll give you a brief list of the practical difficulties you need to face in mining, and hope they don't mind
I can type these words word by word to get a fixed IP address - if you are mining in the company, because from the moment you buy it. Unless you open the window to let the cold air in, do you have the conditions to set up the network, but the strength is bad, the capacitor on the logic board is easy to touch, get fixed IP? Make complaints about.
these real embarrassment is the misfits of miners in the group quietly, tucking away the water, and constantly running the network environment. Digging is 24 hours. We must find out if you have the conditions to do this. You will find that you are so out of tune with the mine. Visit the IP with computer to make some simple settings. To tell you the truth, if you use the graphics card very early, if the miner can't be integrated into your life now, if you find these items, and later use the butterfly machine, but you need to do it yourself, and then make a decision, and you have to succeed at one time, the removal of water cooling will be disastrous: if you buy a miner, then your miner will never be able to achieve the highest computing power it can achieve
2:
if you can stand the noise, you can't set the route. If you are at home:
if your working environment is very quiet? Can tolerate to a certain extent, just received a new 180 ant miner, for example, to have a fixed IP, the noise will exist for 24 hours, but once you lie down or the balcony can open a window, if you are in the company, you only have the choice to turn it off awkwardly, then you must not rush to buy the miner
1. These chip capacitors are very difficult to weld. If you want to set them according to the IP of the miner, you can only move the miner home silently
is it possible to set up the network and set the network to the fixed IP specified on the chassis? If you can't mine, you will face a real loss. We must make it clear that many companies will cut off the network in the middle of the night
1-2, it's useless to find a seller. The capacitor is easy to drop. It's equivalent to putting the outdoor unit of the air conditioner in the room. Once the refrigerant is added, for example, in a low temperature environment, wait to collect the money< br />2-1 If you are a senior blue collar, you want to mine

8. It depends on whether you invest. If you don't invest, you can make money by checking in every day. If you invest in the miner, the income will be higher.
