1. I just know your question. Please look at the following answer:
blockchain is an important concept of bitcoin. It is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
the information websites in the instry now include:
1. Dig chain network: dig chain network is a professional blockchain media information portal. Dig chain network gathers the big data of global blockchain trading institutions, takes technology as the core, creates dig chain index, dig chain flash, dig chain College and other core sectors, excavates the value of blockchain, and serves as a platform for blockchain entrepreneurs, entrepreneurs and experts Blockchain investors provide one-stop blockchain service system
2. Golden Finance: a well-known old station in the instry
3. Color cloud bit: it is also the old cloud in the instry
you can learn more about it yourself.

Where is Nakamoto? In my opinion, Nakamoto may never exist maybe he's just a code, or maybe he's just a name invented by a bitcoin team. Over the years, the outside world has been speculating about the identity of Nakamoto, but no one has ever seen him as a real person{ RRRRR}
the situation of bitcoinfrom the beginning to now, bitcoin has experienced peaks and valleys. Now the value of bitcoin has become stable. It is basically difficult for ordinary people to obtain bitcoin by mining, and the cost is also difficult to control. Therefore, it is basically certain that it is impossible for ordinary people to rely on bitcoin to make a fortune. And now add to join the speculation circle, I personally think it is not very rational. First, we all know the value of bitcoin. There is no cheap way to pick it up. The second is whether bitcoin will play an important role in the future. At present, no one can give a 100% guarantee. Therefore, you need to be careful in currency speculation. If you have to, you should see if you have enough money in your wallet
3. If the blockchain integration system can be connected to the e-commerce platform, it will have the following benefits
1. Both blockchain points and coupons in the blockchain system have permission to use. If businesses do not launch marketing activities in time, then businesses will soon be forgotten by consumers. The way businesses call for points is actually to take what they need, and consumers can exchange points according to their own preferences
2. Enterprises increase the stickiness with consumers and earn more repeat customers by issuing points, which is a way of marketing. After using the blockchain integral system, the logic of consumers' integral use will change, and the blockchain integral can be transformed into a tool for flow realization. Hanquan technology blockchain mall is OK.

4. 1、 About startup settings
for beginners who haven't been in BISO: after boot up, you can see the main menu of CMOS setup by pressing the "del" key
in the main menu, you can select different setting options, press the up, down, left and right arrow keys to select, press the "enter" key to enter the submenu
select advanced BIOS features to enter, and the following are
1st boot device (short for first, which means "first")
2nd boot device (short for second, which means "first"), The third boot device
(first boot device / second boot device / Third Boot device) allows you to set the boot order of the boot device in which the BIOS is loaded into the operating system After entering advanced BIOS features, you only need to find the options of 1st boot device, 2nd boot device and 3rd boot device, and sometimes put them in the "boot sequence"]
first boot device:
A: install the system on CD-ROM (if you want to buy a CD, Please buy a CD with ghost character system)
b: usb-hdd is the best choice for U disk or mobile hard disk (this is a little difficult because it involves the proction of USB boot disk, so it is not recommended for novices, because you will be in a mess if you don't have a good hand to help.)
set to the corresponding mode
2nd boot device: set to HDD HDD stands for hard disk)
then, to save, press F10, the dialog box will appear, press y, and then press enter. If pressing F10 doesn't respond, press ESC to push down the BIOS interface, and then repeat the above operation to save the settings
the system will restart and then enter the corresponding installation interface. You just watch the word operation
2. About BIOS upgrade
1. The operation is not difficult, that is, download the BIOS program, and then (there may be special upgrade software) operate according to the instructions given by it. The general instructions will be attached to the downloaded BIOS program
2. This kind of operation is not recommended. Unless it is for very important functions, such as USB2.0 upgrade 3.0, it is not recommended to upgrade< 3. About the graphics card, I checked the motherboard and CPU performance you gave me. Your machine should belong to the learning / office machine
it is recommended to make do with it and replace it with a new host in two years
if you want to upgrade your graphics card to play games, you can only find a brand new low-end series of graphics cards (second-hand) with an investment of 400 yuan. Remember!!! Don't be greedy for bargains. You can get every cent, especially those fake procts on Taobao. Don't buy them. Just buy the brand that appears on Zhongguancun / Pacific)
please go to Pacific or ZhongGuanCun to find the specific brand of the graphics card. Let me tell you the basic points:
display memory bit width (unit: bit) > display memory frequency > core frequency > number of rendering pipelines
(display memory bandwidth = display memory bit width * display memory frequency)

5. Compared with the total stiffness analysis, the lateral stiffness analysis is a simplified method with less calculation and faster speed. So in principle, try to use the total stiffness analysis, only when your computer performance is insufficient, consider using the lateral stiffness analysis method
if the floor is rigid, there is little difference between the lateral stiffness and the total stiffness
if the actual stiffness of the floor is considered and the elastic plate is set, then the total stiffness analysis should be used for accuracy.

Nmax is Yamaha's scooter, 155cc displacement EFI engine, Yamaha factory in Thailand, the domestic price to more than 20000 yuan
7. Tmax should be the maximum tensile force, and the abbreviation max (maximum) means the maximum. Nmax this should be the maximum pressure
in general physics, t is tensile force and N is pressure
in general physics, t is tensile force and N is pressure
8. I won't do it to you either
9. Generally speaking, maintenance should be carried out to ensure the normal use of the car and increase its service life:
1. Whether the protective coating on the bottom of the car body is damaged
2. Replace the fuel filter and spark plug
3. Check the V-belt and replace it if necessary
4. If the engine timing belt is cracked or damaged, replace it if necessary
5. If the engine oil pan bolts are loose, tighten them according to the specified torque if necessary
6. Check whether the brake hose is aged or damaged, whether the hard brake pipe is damaged or corroded, and whether the joints are leaking
7. Check whether the connections of the fuel system are aging, damaged, loose or worn
8. Check whether the rubber parts and rubber bearings connected between the front and rear frames and the vehicle body are damaged or permanently deformed
9. Check whether the hinge of the left and right control arms and the hinge of the rear axle are damaged or invalid
in addition, the brake fluid must be changed every two years or 50000 km, and the brake alarm system and brake booster must be checked. For manual transmission vehicles, change the transmission gear oil every 12 months or 500 km. Vehicles equipped with automatic transmission should always check the transmission gear oil and change it every 30 000 km
these maintenance items are for reference only. Please refer to the vehicle maintenance manual for specific models.
