T9 computing power
S9 was upgraded to 14T, and the power consumption was only 1400W, which saved too much power
IPFs is a file transfer protocol similar to http. If IPFs wants to run, it needs many computers (storage devices) in the network as nodes. In a broad sense, all participating computers can be called IPFs mining machines
in order to attract more users to join the IPFs network and contribute to the network, an encryption currency named filecoin is designed, which is distributed to the participants (nodes) as a reward according to the amount of contributed storage space and bandwidth. In a narrow sense, the computer specially designed for the purpose of obtaining the filecoin reward is called IPFs mining machine
because IPFs network needs storage space and network bandwidth, in order to obtain the highest profit ratio, IPFs mining machine usually strengthens the storage space and reces the power consumption of the whole machine. For example, more than 10 high-capacity hard disks are equipped, Gigabit or higher speed network cards are equipped, and ultra-low power architecture processors are used
of course, the mining machine provides storage services, so it can obtain revenue. The size of revenue is related to the configuration of mining machinery and the number of IPFs mining machinery
extended data
the reasons why it is not recommended to invest in IPFs are as follows:
1. IPFs technology is too early to be commercialized
IPFs now takes up a lot of bandwidth. IPNs is very slow at present, which is an obvious technical defect. It will be very difficult to realize dynamic web pages only through IPFs
There is no reasonable economic model, even if the token economy is added, it is difficult to realize the long-term natural ecological valueas a very cumbersome decentralized protocol, it is difficult for users to share files autonomously and spontaneously. In addition, even if users share files into the protocol, the files will be completely open and users cannot delete files effectively, so the security of valid files is threatened
the solution is to introce encryption and blockchain incentive mechanism. At the same time, it solves the security and storage power problems of files. However, as mentioned before, any node with workload proof under blockchain incentive mechanism will face an economic problem of continuous power on state
It is difficult to establish an ecological network with IPFs as the core under the influence of technical problems The ecological application space ofIPFs is quite limited, and the project interaction speed realized by IPFs protocol is also very slow. Of course, it has a direct relationship with the number of nodes and the distance of calling
the mining pool is the necessary infrastructure for the exploitation of P2P cryptography virtual currency such as bitcoin (digital currency). It is generally an open team mining server. Its significance is to improve the stability of bitcoin mining and stabilize the miners' salary. At present, the most powerful mining pools in the world are f2pool, antpool, BW pool, BTCC pool and bitfury. Except for bitfury, the rest are from China
with more and more people participating in mining, the computing power of bitcoin network is rising, and it is difficult for a single device or a small amount of computing power to dig bitcoin again. At this time, the mine pool was born
operation principle of bitcoin mine pool
the ore pool is responsible for information packaging, and the access mine is responsible for competing for bookkeeping rights
e to the collection of the computing power of many miners, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher
for example
suppose 1 million people participate in bitcoin mining, and the whole network has 400p computing power, of which 90% of the miners have less than 1p (1000t) computing power. If a 1t miner is put into operation, it will account for 1.400000 of the whole network's computing power. Theoretically, every 400000 10 minutes can dig a block, that is, only 7.6 years can dig a block, and then get 50 bitcoins at a time
then, if I find another 9 miners with 1t dynamometer and reach an agreement, we will have a total of 10 people, and any one of them will be divided equally according to the proportion of each person's computing power, then we are a whole. With a total of 10t computing power, we can dig a block in 0.76 years on average, Then we have five bitcoins mined in 0.76 years. What if we organize 100 people, 1000 people, 10000 people or even 100000 people
if it is 100000 people, I can dig one block in 100 minutes on average. As a member of the team, my income will tend to be stable
this is the basic principle of the mine pool, that is, everyone forms a team to mine bitcoin, you can refer to the "buy together" in the lottery
of course, the above is only a simple description of the basic principles and properties of the ore pool, and the actual situation will be very complicated
the ore pool is a fully automatic mining platform, that is, the ore machine is connected to the ore pool to provide computing power and obtain profits
the bitcoin reward generated by mining in the mine pool will be distributed according to the proportion of each miner's contribution to computing power
compared with single mining, adding to the ore pool can obtain more stable income

3. Hardware analysis
1. Screen: both are equally matched. Xiaomi 10 has a 90hz refresh rate
Xiaomi 10's OLED screen surpasses iPhone 11's LCD screen in color brightness, contrast and HDR video viewing, But the screen quality of the iPhone 11 is not bad at all, and the LCD will not have the problems of screen burning and pixel loss at all. The daily peak brightness can also be maintained very high. Apple's color adjustment is also first-class, and the look and feel is very good
in terms of smoothness, there is no doubt that the 90 Hz screen of Xiaomi 10 directly suppresses the iPhone
2. Performance: A13 continues to press 865865 with 5g support
A13 brings the single core performance and GPU to the extreme. Except for the multi-core performance, snapdragon 865 is inferior in other aspects. In daily use, the single core performance still determines the experience of most applications. The luxurious GPU configuration can play all mobile games
the performance of Xiaolong 865 is also very strong. 5g support is the trump card. 5g will be popularized in big cities in the next 2-3 years. At that time, Xiaomi 10 can experience 5g, but iPhone 11 can't< br />
3. Camera
it's certain that the camera specification of Xiaomi 10 Pro is better than that of iPhone 11. However, Xiaomi 10 has replaced 2 by portrait lens and 10x hybrid zoom lens with make-up lens, which is of average quality. The photography experience of iPhone 11 is better than that of Xiaomi 10, and there is no waiting time for the film to be proced quickly after shooting, Xiaomi's 100 million pixel camera requires too much computing power
4. Charging
although Xiaomi 10 doesn't have the 50W fast charging on Xiaomi 10 pro, 30W will be full soon, and the wireless charging speed is 30W, super fast. The progress of Android flagship in charging specifications in 2020 is really amazing
iPhone 11 can also be charged 50% in 30 minutes by PD charging, but it is still much slower<
5. Dust proof and water resistance - iPhone 11 is undoubtedly better
considering the cost, Xiaomi 10 Pro adopts low-cost p2i life waterproof design this time, iPhone 11's IP68 level is definitely higher, and the possibility of water crash is also smaller< 6. Software system: MIUI or IOS. Who is better to use MIUI or IOS has been discussed for many years< br />
advantages of MIUI:
Super many details and functions optimized for domestic users
display of calling home place, T9 dial-up
integration of notification SMS, anti-interference
customizable theme, font Compared with MIUI, IOS also has many advantages:
system has no advertising design
Apple's multi device linkage
good software ecology
fluent animation and so on
so the two systems are excellent, but the focus is different< In conclusion, Xiaomi 10 has high performance price ratio, excellent performance, 5g support and fast charging speed. However, in addition to the IOS system, iPhone 11 also has outstanding advantages, such as the screen is facing the screen instead of curved screen, Apple's multi device linkage is very good, and so on. So this purchase recommendation is if your budget is 4000 yuan, There's no doubt that it's good to buy Xiaomi 10. If you have a budget of 5500 yuan, choose one of Xiaomi 10 pro and iPhone 11
