Blockchain is worthless in front of quantum computing
blockchain instry presents rapid development, helping the real economy to rece costs and improve efficiency
at present, a new round of scientific and technological revolution and instrial change sweeping the world, big data, cloud computing, Internet of things, artificial intelligence, blockchain and other new technologies continue to emerge, and the digital economy is profoundly changing the way of human proction and life, becoming a new driving force of economic growth. As a disruptive technology, blockchain is leading a new round of technological and instrial changes in the world, and is expected to become
the "source" of global technological innovation and mode innovation, and promote the change from "information internet" to "value Internet"
in China's 13th five year plan for national informatization, blockchain is regarded as a key cutting-edge technology, and it is clearly proposed to strengthen the innovation, experiment and application of new technologies such as blockchain,
in order to seize the leading power of the new generation of information technology. At present, China's blockchain technology continues to innovate, and the blockchain instry has initially taken shape. It has begun to be rapidly applied in supply chain finance, credit reference, proct traceability, right trading, digital identity, electronic evidence and other fields. It is expected to promote China's economic system to achieve technological change, organizational change and efficiency change, and make an important contribution to the construction of a modern economic system
as of June 2018, China's blockchain related business has initially formed a scale under the promotion of the government, enterprises and capital, and is in the forefront of the world in terms of the number of patents, financing environment, policy support and application landing
the instry is developing rapidly, and the number of enterprises is increasing rapidly.
according to the statistical data of in depth analysis report on business model innovation and investment opportunities of blockchain instry published by prospective instry research institute, there were 406 patent applications related to blockchain in the world in 2017, of which 225 were from China. As of the end of March 2018, the number of blockchain based companies in China has reached 456. The blockchain instry has initially formed a scale. From the upstream hardware manufacturing, platform services, security services to the downstream instrial technology application services, instry investment, media publicity, talent services and other instrial chain links are basically complete
from the change of the number of newly established companies in China's blockchain instry, the number of Companies in this field began to increase in 2014, and the number of newly established companies increased significantly in 2016, more than 100, more than three times of 2015. 2017 is the peak period of blockchain entrepreneurship in recent years. Due to the rapid popularization of blockchain concept and the graal maturity of technology, many entrepreneurs swarmed into this field, and the number of newly established companies reached 178
from equipment manufacturing to instrial application, the context of the blockchain instry chain is graally clear.
from the distribution of newly established companies in the blockchain instry segmentation field, as of the end of March 2018, the number of instrial application companies in the blockchain field is the largest, including 86 companies providing application services for the financial instry and 109 companies providing application services for the real economy. In addition, there are more than 40 related companies in blockchain solutions, underlying platforms, blockchain media and communities
from the perspective of the distribution of investment events in the blockchain instry segments, companies related to instrial application services have the largest number of investment events, with a total of 113. It can be seen that investors are paying more and more attention to projects with specific application scenarios that can be actually implemented. The number of events in the field of underlying platform is 42, and the number of events in the field of blockchain media and community is 28. The field of blockchain is attracting more and more entrepreneurs and capital, becoming a new highland for innovation and entrepreneurship. With the development of blockchain technology and the acceleration of application, the instrial scale will continue to increase, and this field is expected to become a new economic growth point in the future
the influx of Internet giants has rapidly promoted the development of China's blockchain instry
blockchain technology is not only favored by start-ups, but also widely concerned by internet giants. Internet giants have expanded their blockchain business and rapidly promoted the development of China's
blockchain instry. At present, Tencent, Alibaba, Internet, Jingdong and other Internet instry giants have joined in the research and scenario application of blockchain technology
the regional distribution is relatively concentrated, and the instrial agglomeration effect is obvious.
from the perspective of the regional distribution of China's blockchain companies, Beijing, Shanghai, Guangdong and Zhejiang are still the concentration places of blockchain entrepreneurship, accounting for more than 80% of the total. Among them, Beijing is in the absolute leading position with 175 companies, accounting for 38%; Shanghai ranked second with 95 companies, accounting for 21%; Guangdong Province ranked third with 71 companies, accounting for 16%; Zhejiang Province ranked fourth with 36 companies, accounting for 8%. In addition, Jiangsu, Sichuan, Fujian, Hubei, Chongqing and Guizhou are among the top ten provinces in China's blockchain entrepreneurial activity
the application of blockchain is diversified, extending from finance to the field of entity
blockchain technology has the characteristics of distributed, tamper proof, high transparency and traceability, which is very suitable for the business needs of the whole financial system. Therefore, it has been applied in payment and clearing, credit financing, financial transactions, securities, insurance, leasing and other sub fields. For example, Minsheng Bank and China CITIC Bank jointly launched the first domestic L / C blockchain application, and Ping An of China's two major application scenarios of asset trading and credit reference have been online. China Merchants Bank has landed the first domestic blockchain cross-border payment application, and Weizhong bank has shortened the reconciliation time from t + 1 day to t + 0 day through the inter agency reconciliation platform based on blockchain, realizing daily quasi real-time reconciliation
with the graal maturity of blockchain technology innovation and development, the actual effect of instrial application has become more and more obvious
now, the application of blockchain has extended from the financial field to the physical field, including electronic information deposit, right management and trading, proct traceability, digital asset trading, Internet of things, intelligent manufacturing, supply chain management and other fields. Blockchain technology began to be deeply integrated with the real economy instry, forming a number of "instrial blockchain" projects, ushering in the era of "a hundred flowers bloom" of instrial blockchain
to realize "informatization of cooperation links" and help the real economy rece costs and improve efficiency, Specifically, we can promote the development of traditional instries from two aspects of "cost rection" and "efficiency improvement"
in addition to low cost and high efficiency, blockchain can also realize "trust transfer" or "trust spillover". Based on blockchain technology, since the information on the chain can not be tampered with, after the two parties jointly verify a transaction, the third party can also trust the information, In fact, this kind of trusted state can be transmitted to a third party, and then realize the capitalization of data. In addition, it is very easy for institutions to turn from the "black box" state to the "white box" state, that is, the operational mechanism of institutions is transparent, which makes it very easy to prove their innocence and greatly reces the cost of mutual trust between multi-agent
Further, blockchain will play the role of "improving the efficiency of instrial chain coordination". To improve the level of instrial collaboration is an important way to promote made in China to move towards the middle and high end, and also an important requirement for building a modern economic system. However, in many instries, the efficiency of instrial chain collaboration is still not high, especially in the field of international tradetechnology abuse leads to certain risks in instrial development, which can not be ignored
although the positive value of blockchain technology graally appears, there are still a series of risks that can not be ignored in the process of instrial development. On the one hand, it is compliance risk. In the early stage of the development of blockchain, because it has the property of transmitting value, it has attracted some behaviors that are not focused on technology application, but are keen on illegal fund-raising, pyramid selling and even fraud through ICO (initial token issue)
the instrial policy system has been graally constructed, and the instrial development environment has been continuously optimized. In December 2016, the notice of the State Council on printing and distributing the 13th five year plan for national informatization first mentioned blockchain, and took it together with quantum communication, artificial intelligence, virtual reality, big data cognitive analysis, driverless vehicles and other technologies as key cutting-edge technologies, clearly proposed the need to strengthen the innovation, testing and application of blockchain and other new technologies, In order to seize the leading power of the new generation of information technology. Secondly, relevant instry, national and international standards are also speeding up to solve the key technical standards of blockchain and promote the ecological development of blockchain instry. In order to grasp the development opportunity of blockchain instry and seize the commanding point of blockchain instry development, local governments timely issued blockchain technology and instrial development support policies, which ushered in a new outbreak of blockchain instry
at present, local governments are actively positioning blockchain technology from the perspective of instry and seizing the new opportunities brought by technology upgrading. For example, in March 2018, the Hebei provincial government issued the guiding opinions on accelerating instrial transformation and upgrading and building a modern instrial system, proposing to actively cultivate and develop future instries such as blockchain and build a world-class high-tech instrial cluster
According to the overall plan of the 19th National Congress of the Communist Party of China, preventing and defusing major risks is one of the priorities of China's economic work in the next three years, and the key to preventing and defusing major risks is to prevent and control financial risks. Therefore, China also actively strengthens instry supervision, prevents possible financial risks in the process of blockchain development, maintains the stability and security of national finance, and promotes the healthy development of blockchain instry, so as to better play the positive role of blockchain "value Internet"blockchain is a cutting-edge technology, and the new regulatory challenges caused by technology also require the continuous progress of regulatory technology. "Reg tech" (regulatory Technology) in the financial technology segment. It is to use new technologies such as big data, artificial intelligence and blockchain to solve regulatory compliance problems and rece compliance costs. Blockchain filing platform and blockchain based regulatory system all belong to the field of reg tech. There have been companies engaged in regulatory technology in China, which mainly provide regulatory technology solutions for the government, major banks and other financial regulatory agencies. Jinqiu technology, zhongxiangbit and other companies have launched a supervision system based on blockchain
5g is 5g
blockchain is the third power of blockchain
it's not clear. Do you want to ask if the three logics of quantum computing
are different, and there is a little sense of mutual promotion
5g solves the problem of wireless transmission speed, which is many times faster than 4G
blockchain was formerly PPP protocol, It is the point-to-point transmission protocol
used to solve the congestion problem of the central node. Quantum computing to improve the download speed is a breakthrough of Moore's law, which can solve the limit problem of computing speed in the limited space
for more information, please refer to this article, what is blockchain, can you explain it easily
in fact, in the real world, even if quantum computing is implemented, if the topology of the whole network is still in accordance with the existing model (the infrastructure will be updated for many years), quantum computers can only greatly improve the computing power on a few nodes and obtain accounting rights, So basically, quantum computing should be safe before it reaches everyone's personal computer.
According to reports, the coin circle, which has been silent for a long time e to the bear market, has been broken recently. This time, Li Xiaolai, who is known as the "richest man in the coin circle" by the outside world, is still standing at the muzzle of the gun
on July 4, 2018, a recording of Li Xiaolai's private conversation spread on the Internet. In this conversation, which lasted for more than 50 minutes, Li Xiaolai denounced the well-known figures and blockchain projects in the coin circle in a vulgar tone, and told the interviewees about his investment tactics as a winner
this recording sounds like an explosion of information, which once again pushed Li Xiaolai to the forefront of public opinion. Due to the sensitive words mentioned in the recording, such as "don't blindly believe in value investment", "sell air currency" and so on, Li Xiaolai was identified as the banker of "cutting leeks" in the currency circle in the later public opinion
at the same time, as a former New Oriental teacher and best-selling author, Li Xiaolai has many fans after entering the blockchain instry. But in that recording, Li Xiaolai thinks that his IP and traffic are very important in the coin circle, while disdaining blind followers
What kind of person is the real Li Xiaolai? What is his way of accumulating real wealth and investing in blockchain? What kind of world is the blockchain instry todayon July 12, 2018, Li Xiaolai received an exclusive interview with the media and responded to questions from the outside world
media: who are you most optimistic about in the blockchain instry
Li Xiaolai: Wu Jihan in mainland China. I think this person is a wounded and bloody soldier in the blockchain instry. About three years ago, I told my friends about it. If there is an opponent in the world that I may not be able to fight, it is Wu Jihan. It's just that we're not on the same track, so it's also my luck
media: your little Luo Yonghao is working hard in instry, and you are working in blockchain. What do you think of the relationship between blockchain and entities
Li Xiaolai: finance is the embodiment of real economy. Finance cannot be separated from the existence of real economy. Blockchain will certainly drive the real instry, but it is still unknown how to drive itI admire Luo Yonghao's work in the real instry. He has a higher sense of happiness than me, because making a mobile phone has a much greater sense of achievement than I do in an unknown instry, and they are more easily recognized by the society
media: did Luo Yonghao comfort you after the recording leakage
Li Xiaolai: our habit is to keep quiet when we are in trouble, because how to comfort others is a very difficult thing. But then we'll talk to each other about what happened
Li Xiaolai: do you have any other questions? Today is my birthday. I'll have dinner with my wife latercontent source: phoenix.com
zero knowledge proof is a technology that the verifier can make the verifier believe a certain conclusion is true and credible without providing the verifier with the information itself. At present, the anonymous transaction of zcash, a digital asset with outstanding anonymity, is realized by "zero knowledge proof"
for example, a has to prove to B that he has the key to a room. Suppose that the key can only be used to open the lock of the room, but no other method can. At this time, a can choose to give the key to B, and B can use the key to open the lock of the room, so as to prove that a has the correct key of the room
or a opens the room with the key, takes an object out of the room and shows it to B. B knows that the object is only in the room. The principle of method two is zero knowledge proof
zero knowledge proof can prove that I know the secret without disclosing the information itself, and can effectively solve many verification problems.
Specifically, users can share the idle storage space and bandwidth resources of cat disk, and these resources will be output to companies such as content, video, game, blockchain, etc. cat disk company will convert the legal currency and various digital currencies paid by the latter into bitcoin, and users will get the corresponding bitcoin income. This is also the unique mining mode of cat disk
why reward bitcoin
because similar procts on the market reward users with points, diamonds and other rights and interests issued by relevant companies, and most of these rights and interests are of low or no value. In addition, those projects that once seemed to be hot are now almost withered, and the early players may benefit, while the late players will lose all their money
as we know, bitcoin is the anchor currency in the digital currency world. Cat disk directly uses bitcoin to motivate users, and users can pick up the coin to their wallet at any time, and their income can be guaranteed. Moreover, the risk of bitcoin breaking is almost zero, and the user's income will be more lasting and stable
how is the mining income distributed when it comes to distribution, we should first introce the concept of "storage power", which is directly linked to the income of cat disk users. Storage power is an index based on users' shared storage space, bandwidth and online time. The larger the storage space, the faster the bandwidth speed and the longer the online time, the larger the storage power, and vice versa the cat disk gains revenue by sharing storage bandwidth resources, and users can check the revenue through app every day, that is, how much bitcoin they earn. The profit distribution of maopan mining is not random, but through a series of calculations. In short, users' daily income depends on their personal storage capacity, all users' storage capacity and the amount of money issued each day. The calculation formula is as follows: single user's daily income = single user's daily storage capacity / all users' daily storage capacity * Daily currency amount it can be seen that users' daily income is positively correlated with the daily storage capacity index and the daily currency amount, and negatively correlated with all users' daily storage capacity index what is the amount of money issued every day the cat disk integrates the storage and bandwidth resources shared by users, provides storage and bandwidth services to the demander, and converts various digital currencies paid by the other party into bitcoin for distribution to users. How much bitcoin is issued every day depends on the actual business situation, so there is no way to give specific figures for the time being. What we can make clear is that, unlike other mining procts, cat disk does not issue its own currency or restrict the mining of a specific kind or several kinds of currency. Instead, it earns various digital currencies paid by others. These currencies are all market currency. Cat disk converts these currencies into bitcoin and distributes them to users note that all the currencies are negotiable, and the more storage nodes, the more business, the higher the overall mining revenue; For other mining procts, the amount of money that can be mined is limited or issued by the owner. With the passage of time, there will be more and more mining machines, and the mining income will be less and less
this problem is actually very simple
your graphics card is OK! But the vertical synchronization of the graphics card is not off, so the FPS is very low. You can turn off the vertical synchronization in the properties of the graphics card
it must be this problem
the properties of the graphics card can be found by right clicking on the desktop, and then properties - Settings - Advanced<

as a rookie, you must pay attention to one thing: when you download something, some websites default to C disk. When you can choose to download the disk, you'd better put it in other disks. You can't choose and you can't help it. The files in C disk are also the places where viruses like to patronize (it's unnecessary to say that there are so many experts in the forum, which is from pediatrics, Sorry)
for users who have been using for a long time, some spare data will be accumulated in Disk C, which takes up too much space. Should we delete unnecessary files:
deleting spare files and freeing up space can make our computer faster and do not waste resources. Delete those good ones
1. Open "my computer" - "tools" - "Folder Options" - "view" - "check the" show all files and folders "option -" OK "
2. Delete the contents in the following folder:
X: &# 92; Documents and Settings\ User name & # 92; Cookies\ All the files under (keep index file)
X: & # 92; Documents and Settings\ User name & # 92; Local Settings\ Temp\ All files (user temporary files) under
X: & # 92; Documents and Settings\ User name & # 92; LocalSettings\ TemporaryInternet Files\ All files (page files) under
X: & # 92; Documents and Settings\ User name & # 92; Local Settings\ History\ All files (History) under
X: &; Documents and Settings\ User name & # 92; Recent\ All files (shortcut to recently browsed files) under
X: & # 92; WINDOWS\ Temp\ All files (temporary files) under
X: & # 92; WINDOWS\ Servicepackfiles (backup files after upgrading SP1 or SP2)
X: &; WINDOWS\ Driver Cache\ The compressed file under i386 (backup file of driver)
X: &# 92; WINDOWS\ SoftwareDistribution\ All files under download
3. If the system has been upgraded with windows upgrade, delete the following files:
X: &# 92; windows\ Then the disk is defragmented, Please exit all running programs ring defragmentation
5. After defragmentation, open "start" - "programs" - "accessories" - "system tools" - "system restore" - "create a restore point" (it is better to use the date at that time as the name of the restore point)
6. Open "my computer" - "right-click system disk" - "properties" - "disk cleanup" - "other options"- Click "clean" in the column of system restore - select "yes" - OK
7. After all kinds of software and hardware are installed properly, XP rarely needs to update files. Delete the system backup file: start → run → sfc.exe / purecache nearly 3xxm The function of this command is to clear & quot; Windows File Protection & quot; File cache, free up the space it occupies)
8. Delete; windows\ system32\ Dllcache DLL file (minus 200-300mb), this is a standby DLL file, as long as you have copied the installation file, you can do so
9. XP will automatically back up the hardware driver, but after the hardware driver is installed correctly, it is not likely to change the hardware, so you can also consider deleting the backup file, which is located in & # 92; windows\ driver cache\ I386 directory, the name is driver.cab, you can directly delete it, usually this file is 74m
10. Delete unused input methods: for many netizens, not all the input methods in Windows XPT system are suitable for their own use, such as imjp8_ 1 Japanese input method, imkr6_ Korean input method these input methods, if not needed, we can delete them. The input method is located in & # 92; windows\ ime\ Folder, all occupied 88m of space
11. Discover windows & # 92 after upgrading; If you have many more directories like $ntuninstallq31889, you can kill them. In addition, you can keep them; windows\ Help directory of things for me is a kind of injury, ha ha... Kill them all
1 3. Turn off System Restore: once the system restore function is used for a long time, it will occupy a lot of hard disk space. Therefore, it is necessary to set it manually to rece the amount of hard disk. Open & quot; System attribute & quot; Dialog box, select & quot; System restore & quot; Options, select & quot; Turn off System Restore on all drives & quot; Check the box to turn off system restore. You can also restore only the disk or partition settings on which the system is located. First select the partition where the system is located and click & quot; Configuration & quot; Button to cancel & quot; Turn off system restore for this drive; Option, and you can set the amount of disk space used for system restore
14. The hibernation function will take up a lot of hard disk space. If it is used less, you may as well turn off the hibernation function; Control panel;, Double click & quot; Power Options & quot;, In the pop-up & quot; Power option properties & quot; Select & quot; Dormancy & quot; Tab, cancel & quot; Enable Hibernation & quot; Check box
15. Uninstall uncommon components: XP installs some system components to the operating system by default, and a large part of these components are impossible for you to use. You can download them in & quot; Add / remove windows components & quot; Unload them. But some of the components XP is hidden by default, in & quot; Add / remove windows components & quot; If you can't find them in Notepad, you can open them in Notepad; windows\ inf\ Sysoc.inf is a file that uses the find / replace function to replace the & quot; hide" Replace all characters with null. In this way, the hidden properties of all components will be removed, and after saving and exiting, run & quot; Add remove programs;, You'll see many more options that you can't see before. Delete those components that you can't use (remember to save them as sysoc.inf instead of the default sysoc.txt), such as Internet messenger service, fax service, Windows Messenger, code table, etc., which can free up nearly 50MB of space
16. Clear system temporary files: system temporary files are generally stored in two locations: a temp folder in the windows installation directory; The other is X: &; Documents and Settings\& quot; User name & quot&# 92; Local Settings\ Temp folder (Y: the partition where the system is located). Files in both locations can be deleted directly
17. Clear temporary Internet Files: regularly delete a large number of temporary Internet files, which will save a lot of hard disk space. Open IE browser and select & quot; Tools & quot; Select & quot; Internet Options;, In the pop-up dialog box, select & quot; General & quot; Tab, in & quot; Temporary Internet files & quot; Click & quot; Delete file & quot; Button, and in the pop-up & quot; Delete file & quot; Dialog box, select & quot; Delete all offline content & quot; Check the box, and click & quot; Determine & quot; Button
18. Clear pre read files: Although the pre read settings of Windows XP can improve the system speed, after a period of use, the number of files in the pre read folder will become quite large, resulting in a longer system search time. Moreover, some applications will proce dead link files, which makes the burden of system search heavier. Therefore, these pre read files should be deleted on a regular basis. It is expected that the files will be stored in the prefetch folder of the Windows XP system folder, and all files in this folder can be deleted
19. Compress NTFS drives, files or folders: if your hard disk uses the NTFS file system, you can also consider enabling the compression function of NTFS. Right click the drive to compress - & quot; Attribute & quot-& quot; General & quot-& quot; Compressing disks to save disk space;, Then click & quot; Confirm & quot;, In & quot; Confirm property change & quot; Select the option you want in the. This saves about 20% of the hard disk space. When compressing C disk, it's better to compress in safe mode, so the effect is better< Dr. Watson: to close Dr. Watson, open the registry editor and find & quot; HKEY_ LOCAL_ MACHINE\ SOFTWARE\ Microsoft\ WindowsNT\ CurrentVersion\ AeDebug" Branch, double-click the auto key name under it, and set it & quot; Numerical data & quot; Change it to 0, and finally press F5 to refresh to make the setting take effect. In this way, it will be canceled. Also in & quot; Start & quot-& gt;& quot; Run & quot; Enter & quot; drwtsn32" Command, or & quot; Start & quot-& gt;& quot; Program & quot-& gt;& quot; Annex & quot-& gt;& quot; System tool & quot-& gt;& quot; System information & quot-& gt;& quot; Tools & quot-& gt;& quot; Dr Watson"， Call out Dr. Watson in the system and only keep & quot; Dump all thread context & quot; Otherwise, once the program goes wrong, the hard disk will read for a long time and take up a lot of space. If this is the case in the past, please find the user.dmp file, which can save dozens of MB of space after deletion
21. Close remote desktop: & quot; My computer & quot-& gt;& quot; Attribute & quot-& gt;& quot; Remote & quot& quot; Remote desktop & quot; The & quot; Allow users to connect to this computer remotely & quot; Remove the tick
22. Cancel XP's support for zip: Windows XP opens the support for zip files by default, which takes up a certain amount of system resources. You can choose & quot; Start → run & quot;, In & quot; Run & quot; In the dialog box, type & quot; regsvr32 /u zipfldr.dll"， Enter to confirm that XP can cancel the zip decompression support, thus saving system resources
23. Turn off error report: when an application makes an error, a window will pop up to send an error report. In fact, such an error report is almost meaningless to ordinary users, so it is a wise choice to turn it off. In & quot; System attribute & quot; Select & quot; Advanced & quot; Tab, click & quot; Error report & quot; Button in the pop-up & quot; Error reporting & quot; Dialog box, select & quot; Disable error reporting & quot; Radio, and then click & quot; Determine & quot; That's it. In addition, we can also turn off error reporting from Group Policy: from & quot; Run & quot; Type & quot; gpedit.msc"， Run & quot; Group Policy Editor & quot;, Expand & quot; Computer configuration → management template → system → error reporting function;, Double click & quot; Report errors & quot;, In the pop-up & quot; Attribute & quot; Select & quot; Disabled & quot; The & quot; Reporting errors & quot; Disabled
24. Turn off unused devices: Windows XP always tries to install and manage drivers for all devices of the computer, which will not only slow down the system startup speed, but also cause a large amount of system resources. In view of this situation, you can disable PCMCIA card, modem, infrared device, printer port (LPT1) or serial port (COM1) and other uncommon devices in the device manager. The method is to double-click the device to be disabled and click & Qu in its properties dialog box
therefore, if you only want to buy a smart hard disk, it is recommended that you buy a cat disk (with proct version). If you have higher requirements for storage space, you should buy a 2TB cat disk, otherwise 1TB is enough. If you can't use so much storage space and want to share the idle space and get the corresponding reward, buy the cat disk (mining version)
as for the second question, I think whether the cat dish is good or not should be answered from two aspects
one is storage performance, that is, upload and download speed. The official claims that the maximum transmission speed of local area network can be 100 m / s. But this is an ideal situation. When I use it in practice, the upload and download speed of LAN is about 15m / s. Of course, browsing large files or videos at this speed won't get stuck
Q group specially listens to users' questions, and then adjusts them according to users' needs. Now this cat disk uses all kinds of tools. In terms of functions, it can automatically back up mobile phone photo albums and manually back up all files. Personal space is private (with gesture lock). A cat disk can also be shared by multiple members to save idle space. The sharing and sharing functions are very powerful. There is no limit of 9 or 20m, and video documents can be sent to anyone in the form of links, When the other party receives it, they can click it to see it. They don't need to download it. It's very convenient. Cat disk adopts IPFs distributed storage technology, data can be scattered and stored on the IPFs network of cat disk, which is absolutely safe and private, which is really good. Overall, Xiaomi Jingdong endorsed that this proct is of good quality.
