Can bitcoin transfer money without synchronization

1. Computers with bitcoin clients are called nodes, and all nodes on the Internet constitute a bitcoin network. Whenever a new bitcoin is generated and traded on a node, the node will broadcast to the nearby bitcoin node, and finally the whole network node will record the transaction information
in the bitcoin network, each node with a client installed has a distributed database to manage bitcoin proction, transaction, query account balance records, and update and record the latest records of changes in the bitcoin system
when you want to send 10 bitcoins to your friends. You need two things, one is the bitcoin address, the other is the corresponding private key. Bitcoin addresses are different from bank accounts. You don't need to sign a bunch of documents to apply for them. They are randomly generated, just a string of letters and numbers. The private key is also a similar string, but this is strictly confidential. The bitcoin address is like a transparent piggy bank. Everyone can see what's in it, but only the person with the private key can open it.
after you send the transaction application, the surrounding nodes will check whether your account has 10 bitcoins. If there are, they will agree to the transaction, and broadcast the message to the nearby nodes, which will be transmitted from one to ten, and from ten to 100, Soon the whole network will confirm the transaction information and write it to the block. Your friend will receive 10 bitcoins, and the transaction will be completed.
if you want to send small bitcoins, in theory, digital currency can be cut infinitely. At present, the smallest bitcoin unit is called "Nakamoto Tsung", which is equivalent to 0.00000001 bitcoins.

2. The method is to turn bitcoin client into green version, but it may have unpredictable problems to open it at the same time, so please experiment with small wallet first. The green method is to run the client exe with shortcut and parameters, bitcoin-qt.exe - dataDir = e: &# 92; Bitcoin, = followed by the path of the database folder. The default location of the database folder is% appdata% & # 92; Bitcoin added: because the wallet file is located in the database folder, so to open more at the same time, you need two database folders to put the wallet file in, and it's better to two client folders to run separately. In this case, I don't know if there is any risk in the transfer. Let's experiment with it.

The address of bitcoin's wallet is just a record of several public books on the bitcoin blockchain network.

< / OL >

I hope my answer can help you. It is recommended that you fully study before you operate< br />

4. Bitcoin has been restricted

5. It's five seconds. This requires an internationally recognized RTXP Internet financial agreement to enable quick global transfers. The radar currency is international Alipay. Bitcoin does not have the function of quick transfer

6. 1. CPU and graphics card mining for a long time, it is relatively easy to damage or lead to graphics card performance degradation

2. It is recommended to use gpu-z to detect the hardware temperature ring use. If the temperature is relatively high, it is recommended to use a small fan in the chassis to assist cooling.

7. Bitcoin wallet has a large amount of data, many areas and dozens of G's. If it's the first synchronization, it's normal.

8. Depending on the reasons, it may be that the amount of bitcoin is too low to pay the transfer fees, or it may be that the account authentication problem leads to the failure to withdraw cash

9. Mining in order to rush up the sub magic glove mining plus 5 is necessary, which can save you a lot of time. First of all, it's necessary to explain. I don't think it's necessary to take a mining map to find it. A map is not big enough. You can find out where to brush it if you visit it twice. If you blindly pursue mining by mining map, you may be misled. There is also the practice of mining to take less time to practice, such as 2 o'clock in the evening, ha ha. Before 75, you can go outside the main city to mine copper and smelt copper. After 75, you can go to the map above the barren land. Copper mining and tin mining have smelted bronze until 125 (if FM + 5 to 120 is OK, it's the same at the back, you can leave 5 o'clock in advance). This is a difficult stage. Don't speculate and want to find a fixed place to brush silver, That would be futile. 125. The recommended location is arahi highland. Turn around the surrounding mountains. If you have a hole, you can enter it. If no one grabs it with you, it won't take long to reach 175. The recommended place for collecting Mithril is wasteland or cintland, both of which are Mithril paradise. If someone grabs it from you, change it to another map. It's also around the mountains. It's important to note that there is a cliff on the far right side of singland. Don't fall down. If you don't fall down and you're not dead, I suggest you drown in the water and resurrect directly. In these two places, 250 is the best. The recommended location for silver mining is burning plain or feywood. There are several ore brushing spots in fat man cave, but it's not easy to find out which cave it is in. Therefore, if you are not familiar with the situation in the cave, it's recommended not to mine it. Just go around the mountain. These two places don't need to stay for long. Just go to 275. 275 the wormhole of hilisus, the recommended place for collecting silver from fuser, is absolutely paradise. As long as you choose the time to rob no one, it will soon be 300. The key is to be familiar with the wormhole map. Or you can choose to go to Dongquan Valley, where there are many rich mines, but the map is too big to run. 300 magic iron ore Hellfire Peninsula, turn around Hellfire, if you have big birds, of course it will be quite fast. Again, don't believe in the distribution map of mineral deposits. Your memory is better than anything else. It's only 330 here. Daofeng mountain, 330 Jingjin mine, is really a paradise for miners. You can graate here

10. If the credit card is frozen, it can be unfrozen under certain conditions. Please call the credit card customer service center< (1) if the credit card is frozen e to overe payment, the overe amount should be paid back as soon as possible.

After that, the cardholder should pay back on time, so as not to cause overe payment, Because credit card overe will be included in the personal credit system, too many overe times will affect future loan applications

② the freezing of credit card caused by credit card cash out depends on the situation.

③ if a credit card is frozen e to swiping, the bank will unfreeze it after the swiping is completed.
