Computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second

in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow

< H2 > extended data

computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value

therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

unit of force

1 KH / S = 1000 hashes per second

1 MH / S = 1000000 hashes per second

1 GH / S = 1000000000 hashes per second

1 th / S = 100000000000 hashes per second

1 pH / S = 100000000000 hashes per second

1 eh / S = 100000000000 hashes per second

3. 0.03 bitcoin, about 17 yuan

4. In fact, people will not let such a thing happen, because once someone controls 51% of the computing power of the whole network, the security and non tamperability of the system will be invalid, then the decentralization system of bitcoin will collapse, and the price of bitcoin will plummet or even return to zero, which is bad news for the participants of the whole network. Therefore, we will spontaneously control the distribution of computing power in the whole network, so as not to let one company dominate. Even when many people find that the computing power of a certain mine is too large, they will take the initiative to withdraw from the mine. Now the most powerful mining pool in the whole network accounts for about 25% of the whole network.

5. I've been on the news, and the platform is quite reliable

6. Now it's about 0.03btc, you can find a special query website.

9. Because our LAN doesn't allow to assign the same IP address of the same network segment, we can't assign the virtual operating system an IP address of the same network segment with the PC by bridging. This paper uses NAT connection to realize this configuration. Install VMware software in WinXP system
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
