How to count the computing power of the whole network
2. If no one mines, there will be no computing power and no block, so bitcoin will not be proced naturally. The current situation is that with more and more people mining, more professional mining machines and more computing power, the 2100W bitcoin set will be fully mined in 2140.
You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
BTC full network computing power 153.280eh/s, mining difficulty 21.72t, current block height 672055, theoretical income 0.00000690/t/day
the total network computing power of eth is 418.403th/s, the mining difficulty is 5380.94t, the current block height is 11923460, and the theoretical profit is 0.00709464/100mh/day
BSV network computing power is 0.544eh/s, mining difficulty is 0.08t, current block height is 675889, and theoretical income is 0.0081/t/day
BCH's whole network computing power is 1.596eh/s, mining difficulty is 0.20, the current block height is 676209, and the theoretical profit is 0.00056395/t/day<

In addition to the fixed parking lot in the map, there are also temporary parking spots on both sides of the urban streets in the core business district of Nanning. The parking fee is 3 yuan / hour. There is a large flow of people near Heping shopping mall and trading ground, so it is suggested that people should not drive to Heping shopping mall; Before the festival, there are a lot of traffic and people, so please pay attention to safety

2. Open VMware and install RedHat Linux
3. All are ready and start network configuration
4. Let VMware network adapter VMnet8 automatically obtain IP address and DNS server address, then we open ms-doc console and execute ipconfig / all command to see the IP allocation of VMnet8
the IP address configuration of my VMware network adapter VMnet8 virtual network card is as follows: 5. Open the VMware software, select the menu VM settings, select the network card to view its properties, and set the network connection to C ustom:Special virtual network -- VMnet8(NAT) OK, return to the main interface of the software. When starting the RedHat Linux 9 system, we need to set the IP address of the virtual system to the same network segment as it (here I am 192.168.65.0, your IP address may be different, this is an IP address automatically and randomly assigned by VMware)
on the command line, you can edit the / etc / sysconfig / network scripts / ifcfg-eth0 file, The contents are as follows:
device = eth0
bootproto = none
broadcast = 192.168.65.255
IPADDR = 192.168.65.228
netmask = 255.255.255.0
Network = 192.168.65.0
onboot = yes
type = Ethernet
userctl = no
peerdns = no
gateway = 192.168.65.2
DHCP_ Hostname = 192.168.65.254
after saving the settings, reactivate eth0 port:
# service network restart
IP address can be assigned by DHCP server, because after installing VMware, there will be a virtual DHCP server virtual machine to assign IP address. This DHCP server is actually a system service, which can be assigned in the control panel & shy- Management tool & shy- I see this service in the service
in NAT mode network, the gateway of virtual machine points to 192.168. X.2, x = 65 in this paper. This is the address of virtual NAT server. It is also a server virtual machine, which can be seen in service management
6. In this way, WINXP and Linux can ping each other. If you can't Ping, see if your Windows Firewall doesn't allow ICMP
7. Next, we want another PC to be able to SSH login and access the virtual Linux system in the configured PC through LAN. Here we need to do a mapping. Open manage virtual network (in the start menu, or in the VMware interface menu). Open the NAT page and click Edit.. - port forwarding - add
host port: 22
forwarding IP address: 192.168.65.228 22
