2. The consensus model of Chongqing jinwowo analysis blockchain technology is as follows:

the data exchange process of each node is not tampered with; Exchange history cannot be tampered with

the data of each node will be synchronized to the latest data, and the latest data after consensus will be recognized

based on the principle that the minority is subordinate to the majority, the data maintained by the whole node reflects the exchange history objectively.

3. Chongqing jinwowo analyzes the role of consensus in blockchain:
consensus is the core vocabulary of blockchain world. In the distributed network, only if each node follows a certain consensus mechanism, the blockchain can run smoothly
consensus mechanism can be described as the meridian of blockchain. Because the blockchain is polycentric, there is no authoritarian organization in the system.

In addition, some mobile phones have hardware level anti root, so think twice before you start, and now mobile phones don't need root very much

8, system update: generally, it is recommended to update the system for the first time for new mobile phones. Normally, it is mainly bug repair updates, especially if frequent updates are launched
9. Battery life of mobile phones: battery capacity depends on battery life. At present, most mobile phones are 3000 MAH, and the difference is not more than 1000 MAH, which means that the difference in battery life is less than 30%
10, mobile Internet access and signal and network speed: normally, it depends on the network coverage strength and degree of the selected SIM card service provider. In theory, mobile phone manufacturers do not plan to create a machine to receive signals for criticism, so normally, they do not need to consider these problems. In case of encountering these problems, it is at most a case! That is to say, if you feel that the Internet is slow, you can give priority to consulting network service providers
11, screenshot of mobile phone: Android mobile phone, volume down key + power key is the simplest way to take a screenshot
12, headphone socket problem: there is a small fragment in the headphone socket. Insert the fragment into the headphone and press it to start the headphone mode. Pull out the fragment to reset and exit the headphone mode.

14, activation: Android phones generally do not have any activation problems, if there is an official activation tutorial provided by the brand
15, wallpaper and dynamic wallpaper: Android system generally provides wallpaper and dynamic wallpaper settings. Of course, if you don't know clearly, you can download some wallpapers or dynamic Wallpapers directly. App installation and use will be easier
16, most of the settings of Android system ringtones are: settings ~ sound and vibration ~ selection of content to be replaced ~ selection of appropriate ringtones! Or with the help of some app application support
17, mobile phone heating problem: under normal circumstances, it is a good solution to check the power consumption of mobile phone software and hardware with the help of power management software, make targeted adjustments, and rece the residence of background programs. Of course, if it is extremely serious, you should go directly to the merchant for after-sales maintenance
18, call recording: if the brand is not prohibited, you can choose to record in the call interface
19, wechat al open: at present, most mobile phones, as long as the mainstream level or above, support al open wechat, even if the system does not support it, they can also use third-party software to support it
20, fool boot problem: search the buttons on the mobile phone, there is a semicircle and a vertical is the boot button, you can press to see
21, al card switching problem: as long as al card is supported, the data flow icon can be seen in the drop-down menu. Click to select other telecom service providers. If it is not possible to switch, disable the available SIM cards and see if other service providers can use data flow
22, which is a good mobile phone camera software and how to take photos: the suggestion is to try to choose the camera software provided by the brand official, don't use the third-party software! As for skills, be familiar with the functions of these camera software
23, who is good at the performance of mobile phone? Problems in Caton: the ability of game and card to watch processor! The ability of processor determines the performance of mobile phone, which can be understood by antinutu website. At present, it can be roughly classified as follows:
① the 1000 yuan machines with snapdragon 636 processor and snapdragon 625 processor range below belong to the mainstream, but the requirements are not too high. Most mainstream games can be played, and the daily needs of machines of this level can be smooth enough
2. With Xiaolong 660 as Xiaolong 710 processor, as long as you don't require extreme, almost any game can be quite smooth. Of course, daily application is no problem
3. For machines with snapdragon 835 processor, few games can embarrass them even under extreme requirements, let alone daily needs
24, return and exchange of mobile phones: most of Chaotian's newly purchased machines now support return and exchange within 7 days without any reason. After all, there is no answer to the quality problem. So in case of a problem, as long as you are not sure that it can be solved, you need to consult the staff of the after-sales service center of the brand merchant for the first time. This can effectively avoid the quality problems caused by their own economic losses. Of course, such as water, broken screen and other personal factors, in the absence of the corresponding insurance, it is necessary to pay the maintenance fee (the number depends on the situation)
25. At present, most domestic computers are modified and optimized based on a certain version of Android system, and there is little difference in essence
26. Mobile phone's body capacity: Android phones rely on memory, and the appropriate size of memory is very important. As for the body memory, in addition to knowing the type of memory, you can choose the capacity according to your own needs. Too large is actually a waste of space, and many people can't use so much space.
