Maintenance of bitcoin network
Publish: 2021-05-12 13:48:45
1. You may have been delayed in bitcoin transactions. For this reason, okcoin makes the following explanation on the concerns and doubts of users
methods / steps
1 bitcoin network is a global P2P network, which is jointly maintained by all the nodes (which can be understood as computers) accessing the network. On average, the global network (not a company or an indivial) will confirm the transaction once every 10 minutes. According to the network rules, the bitcoin received by the user needs to be confirmed six times (that is, one hour) before it can be used by the user to pay again
2 recently, bitcoin's arrival speed is slow, because there are too many transactions in the whole bitcoin network, and the block capacity is close to the upper limit, resulting in the congestion of bitcoin network, and slowing down the confirmation of bitcoin on major trading platforms. This is determined by the characteristics of bitcoin network itself and is not controlled by the trading platform
3 generally speaking, if the transaction is not confirmed by the bitcoin network for more than 3 days, bitcoin will be returned. Unconfirmed bitcoin will not disappear, please don't worry. This process is determined by the characteristics of bitcoin network itself, and the trading platform cannot intervene in the operation. Therefore, please wait patiently for the confirmation or return of bitcoin network
4 there is no way to cancel the exported bitcoin, which needs to be confirmed by the bitcoin miner; If you want to speed up the confirmation, you can appropriately increase the service charge paid to the miners, which is not collected by the platform.

2. There are several problems in the development process of bitcoin:
1. Supervision. Decentralization is the biggest advantage and the biggest disadvantage of bitcoin; Because it is easy to be used for illegal trade
2. The problem of trading platform. At present, the domestic bitcoin trading is closed, but the foreign bitcoin trading market is hot and there are many platforms, so it is difficult for users to distinguish the legitimacy of the trading platform
3. As for the transaction risk, the bitcoin development team is only responsible for the development, maintenance and improvement of the bitcoin system, but it is unable to guarantee the normal progress of the transaction
4. As for the identity of the trader, generally speaking, the trading platform authenticates the user's real name, but the coin pack thinks that there are still some loopholes in this kind of authentication
5. Legitimacy. Because different countries have different views on bitcoin, they have different views on bitcoin.

3. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items< On February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
hope to adopt

4. 1. MacOS version requirements: click from the top menu of the screen- About local system report... Open the system report app, find the "software" column in the left column and select it. View the system version column on the right:
system version: MacOS
10.12.1
(16b2657)
if your system version is less than 10.12.1, Please check the update and install it through app
store (or download the combined update installation image from Apple support website for manual installation). If you have installed 10.12.1 but the version number is less than 16b26xx, it means that the 10.12.1 you installed is not the latest version. You need to download the combined update installation image from Apple support website for manual installation
MacOS

2. To enable the native touch
bar function, you need to use your apple
ID to download Xcode from the app
store (about 15g of disk free space, if you are the developer of MacOS or IOS, Congratulations, you can continue). After installation, open Xcode and select
window show
touch
bar from the menu of Xcode at the top of the screen, You will find that the touch
bar is already displayed on the screen. At this time, you just need to keep Xcode on (which can be minimized). You can experience and use touch
bar as much as you want. Just like the entity touch
bar, you can open the system preferences app, customize your touch
bar display mode in the "keyboard" item, and also customize the buttons on the control bar. You can even choose display custom multi touch
bar from the menu of apps that support custom touch
bar to customize the application control bar. Yes, you now have the full function of touch
bar. The only difference is that touch
bar is directly displayed on the screen. Of course, you have to use the touch pad or mouse instead of touch and click. Finally, you need to find a suitable location for the touch
bar window on the screen
3. Another scenario: if I am an ordinary user and do not want to download Xcode, or the available disk space is not so large, can I not experience touch
bar
of course not. If you can't turn on this function directly, there will always be a big God who can transplant the function to make it run independently. Download a file called
touch é
app
note: the system should refer to point 1, otherwise it will not work. On the other hand, although the two look similar, Xcode turns on calling the native functions of the system,
touch é
it is the version transplanted by Dashen, and its reliability may be slightly poor. You can check the update from time to time to see if there is any repair or improvement (you can also turn on the automatic update function)
finally, of course, there is still a gap between the experience and the entity touch
bar, such as the lack of the function of word selection and association when inputting Chinese. Emoj can only choose the most commonly used one. If you want to have a perfect experience, you are recommended to use a touch
bar device.

5. Excuse me, where did you buy it? As far as I know, there are so many swindler bitcoin platforms now that you can't get money out of them
it is recommended to ask the customer service about the situation first, and save the evidence of buying money, and prepare to call the police
in addition, you must go to the platform with good reputation in the future, and don't try to be cheap.

6. Bitcoin has been banned by the state! So it's normal that I can't open it! The bitcoin network is out of order and is being upgraded!
7. If the software is updated, the network display is slow. You can go to the official website to see if there is an update package. Generally, the app and the network do not support this. In addition, there is a problem with your network itself. A series of problems caused by poor signal will appear, and the software can't be opened. This kind of problem is common in general software, Change your mobile phone and download it to see if it's the same problem, then you'll know it's the same problem.
8. Bitcoin solves a technical problem, not an economic one
9. There is no relationship between the two, but recently many hackers attack computers and then extort bitcoin. Personal or corporate computers need to be mainly secure and data backup
