IPFs is just an underlying technology, a point-to-point distributed file system
filecoin is the incentive layer based on IPFs and blockchain. Only filecoin has token
at present, filecoin is still in the stage of testing network, and there are many mining machines on the market, so whether we can dig out coins or not needs to be marked with a "question mark". At present, it is the stage of test network, and the configuration of future filecoin miner needs to be studied. You can pay more attention to the test network to help you understand the chain of filecoin

2. Since August this year, Chinese diggers, the so-called miners, have been dominating the price of bitcoin. The sharp rise from August to early December is entirely e to the increase in mining costs and difficulties caused by the accumulation of miners. At the same time, there have been many crazy money speculators for a long time. In three months, the price of bitcoin has risen from 2000 to more than 5000. For many people, the evil spear in Fuhua Dian Jiaodian temple is a myth, However, bitcoin is not a security, so there is no risk prevention and control. Based on the consideration of transaction security, the central bank "suggests" (because it only suggests that there is no travel regulations at present) that the third-party payment institutions stop providing payment and cash withdrawal services to the bitcoin trading platform. As soon as the news comes out, the bitcoin trading price plummeted within four days, and today's price is less than 3000 yuan, However, according to the market analysis, the price is likely to pick up. The main reason for the price decline is that the major payment companies have taken emergency measures to avoid the central bank's words, which has caused the payment obstacles and led to the price drop. However, it seems that this will create a new group of investors, and the price drop will give speculators a new opportunity to re-enter the game, So my conclusion is that the price will rise, but it will not be as crazy as it used to be. It is estimated that the price will go up and down in 3500 after two or three months of tossing. At the same time, the rise and fall will also be significantly reced. It is difficult to go up and down in hundreds and thousands like now, As a senior miner, I hope my answer will help you. Haha, it suck if you don't use it correctly.
3. Bitcoin is a peer-to-peer network-based anonymous digital currency. Peer to peer means that there is no central authority to control the money transfer channel. On the contrary, the tasks of these money transfers are collectively managed by network nodes. Anonymity means that all parties can hide their true identities. Advantages: no need to trust intermediaries, can easily carry out Internet remittance. Third parties cannot control or block your transactions. It avoids the hidden danger caused by the bad policy and instability of the central reserve bank. The limited currency inflation of bitcoin system is evenly distributed (determined by CPU) in the whole network, rather than monopolized by banks. Bitcoin is an open source project proced by Satoshi Nakamoto, and its R & D website is at SourceForge.

In the future, the value of bitcoin will continue to rise, mainly e to the following reasons:
1. The value of bitcoin will rise over time in design
2. As the transaction volume of bitcoin is increasing every day in the world, the total amount of bitcoin and bitcoin generated every 10 minutes will decrease (that is, the bitcoin implemented on July 10 will be halved), The value of bitcoin will continue to rise in the foreseeable future
The dollar and many other fiat currencies are depreciating every year, which is e to inflation, that is, the increase of money supply. Bitcoin is designed to be deflationary4. Since now, the supply of bitcoin has been reced again, that is to say, bitcoin has been "halved", recing the number of bitcoins proced every ten minutes. At present, the reward for each block is 12.5btc
There is no proction limit on the quantity of US dollar, so it may be inflated by the order of the government or the central bank group. Paper money (legal tender) is usually inflated by trying to pay off excess debts or by paying for war But in bitcoin, there is no debt, inflation and bleeding. I would say that we are on the way to a good ideological start7. Bitcoin now has a bifurcation battle, but the market fluctuation is relatively stable, which proves that many countries in the world need it. If you split a coin into two. If your assets exceed 10 million, I suggest you invest 10%
5. BTT is the incentive token on BitTorrent (bitstream), and Chinese is the stream token. For BitTorrent, the early Internet practitioners are very clear. At that time, the network download was very slow, and many students would use BT download resources in dormitories. This protocol enables client software endpoints to cooperate with each other, so as to efficiently and reliably distribute large files to multiple clients. The more users download, the more users, The faster the speed is, BitTorrent can be regarded as the originator of decentralized system application
BitTorrent was originally a point-to-point distributed communication protocol born in 2001, with more than 100 million users. Last year, the Tron foundation officially issued a community open letter, announcing the acquisition of BitTorrent company, which marks the strategic partnership between BitTorrent agreement and Tron wave blockchain agreement
in 2001, Bram Cohen invented the BitTorrent agreement. On September 22, 2004, BitTorrent company was established. On July 24, 2018, Tron foundation completed the acquisition of BitTorrent company. On January 20, 2019, BitTorrent token (BTT) was issued on Tron. On January 28, 2019, BTT was put on sale in binance launchpad
Bram Cohen, also translated as Bram Cohen, is known as the father of BT and a computer programmer in the United States. His software BitTorrent makes him famous. He is also one of the founders of codecon, the organizer of bay area P2P hackers conference and the writer of codeville. What's more famous is that he personally developed and designed the famous game platform steam. In history, BitTorrent once appeared as a rule breaker, which has a profound impact on the Internet. At the peak of 2006, BT traffic even accounted for 70% of the total network traffic, and almost all the download software we use now is improved on the basis of BT. However, e to the business model and other reasons, BitTorrent failed to become a profitable company. On the 30th day after BitTorrent was acquired by BoChang, the founder Bram Cohen announced his resignation. At present, the actual controller of BitTorrent is sun Yuchen

10. [teaching] if you are afraid that BT download will damage the hard disk, please go to
[required reading] let pseudoscience go to hell - does frequent reading and writing of hard disk really damage the hard disk and does flash get really damage the hard disk V5 version
to explain in advance, I only mentioned flash get here, but did not mention ed and FTP
because their principles are the same, I don't want to type one by one.
let me stress that
I just mentioned flash get
but it works the same as ED and FTP.
the so-called loss of the hard disk is also
to quote someone's words first
why frequent reading and writing will damage the hard disk
the life of the magnetic head is limited. Frequent reading and writing will speed up the wear of the magnetic head arm and the magnetic head motor. Frequent reading and writing of a certain area of the disk will increase the temperature of the area, affect the stability of the magnetic medium in the area, and lead to reading and writing errors. High temperature will also make the area closer to the disk surface e to thermal expansion (normally, the magnetic head and disk surface are only a few microns, More recently, It will also affect the data reading sensitivity of the thin film head, change the clock dominant frequency of the crystal oscillator, and cause the failure of the hard disk circuit components
too many tasks will lead to the premature damage of IDE hard disk. Due to the deficiency of IDE hard disk, too many task requests will increase the failure rate of seek and lead to frequent reset of the head (reset means that the head returns to 0
track for re seek) to accelerate the wear of the head arm and head motor<
let me talk about the working principle of modern hard disk first
today's hard disk, no matter ide or SCSI, adopts & quot; Winchester "technology, have the following characteristics: 1. Magnetic head, disk and moving mechanism seal. 2 The surface of the fixed and high-speed rotating plated disk is flat and smooth. 3 The head moves radially along the disk. 4 The magnetic head starts and stops in contact with the disk, but it is in flight and does not directly contact with the disk
disk: magnetic powder is attached to the surface of aluminum alloy (new materials also use glass) disk. These magnetic powder are divided into several concentric circles called magnetic track. On the magnetic track of each concentric circle, it seems that there are countless small magnets arranged arbitrarily, which represent the states of 0 and 1 respectively. When these small magnets are affected by the magnetic force from the head, the direction of their arrangement will change. Using the magnetic force of the magnetic head to control the direction of some small magnets, so that each small magnet can be used to store information
disk body: the disk body of a hard disk consists of multiple disks, which are overlapped and placed in a sealed box. Driven by the spindle motor, they rotate at a very high speed, with a speed of 3600450054007200 or more per minute
head: the head of a hard disk is used to read or modify the state of the magnetic material on the disk. Generally speaking, each magnetic surface has a head, starting from the top and numbering from 0. The magnetic head is in contact with the disk when it stops working, but it is flying when it is working. The magnetic head starts and stops in contact with the landing area of the disk. No data is stored in the landing area. The magnetic head starts and stops in this area, and there is no problem of damaging any data. When reading the data, the disk rotates at a high speed. Due to the delicate aerodynamic design of the head movement, the head is in a "flying state" with a height of 0.2-0.5 μ m from the disk data area. It does not contact with the disk surface to cause wear, and can read data reliably
motors: all the motors in the hard disk are brushless motors, which can work continuously for a long time with little mechanical wear under the support of high-speed bearings. The high-speed rotating disk has obvious gyroscopic effect, so the hard disk is not suitable to move, otherwise it will increase the working load of the bearing. The track finding feeding motor of hard disk head mostly adopts voice coil rotary or linear motion stepping motor, which can accurately track the track of disk under the regulation of feeding tracking, so there should be no impact and collision when the hard disk is working, and it should be handled with care when moving
when it comes to the principle, do you understand it
first of all, there is no contact between the magnetic head and the data area, so there is no wear problem
secondly, as soon as you turn on the hard disk, the spindle motor can rotate at 4500 or 7200 rpm, which has nothing to do with whether you use flash get or ed. as long as the power is on, they will rotate. Their wear and tear has nothing to do with the software
thirdly, the movement of the magnetic head controlled by the seek motor moves back and forth from left to right, and the amplitude is very small. It starts from the innermost layer (landing area) of the disk, slowly moves to the outermost layer, and then slowly moves back, one track goes to another track to find data. There won't be any big jumps. So its wear and tear can also be ignored
so, how does heat come from
the first is the rotation of the spindle motor and the Pathfinder feeding motor, which is the main reason for the temperature of the hard disk
secondly, the friction between high-speed rotating disc and air. This is also the main factor
while hard disk read / write
it's a pity that its calorific value can be ignored
the reading operation of the hard disk is that the change of the magnetic field on the disk affects the resistance value of the magnetic head. In this process, the disk will not generate heat, but the magnetic head will generate a little heat because of the change of the current. What about write operations? On the contrary, the current intensity through the magnetic head changes constantly, which affects the magnetic field on the disk. Because of the use of electromagnetic inction in this process, the heat of the magnetic head is larger. However, the disk itself will not generate heat, because the permanent magnet on the disk is cold and will not generate heat e to the change of magnetic field
but in general, the calorific value of the magnetic head is nothing compared with the former two
heat can be radiated and concted, so will high heat damage the permanent magnet on the disk? In fact, the damage is very small. The degaussing temperature of the permanent magnet is much higher than that of the hard disk under normal conditions. Of course, if your chassis doesn't heat well, it's nobody else's fault
here I have to say a few mistakes of someone:
one. The high temperature affects the resistance sensitivity of the magnetic head, so the read-write error occurs, which has nothing to do with the permanent magnet
two. The so-called thermal expansion will not shorten the distance between the disk and the magnetic head, because the flight of the magnetic head is based on the principle of aerodynamics, and it always keeps a certain distance from the disk under normal conditions. Of course, if you hit hard drives hard, then the shock
three. The so-called seek means that the hard disk moves from the initial position to the specified track. The so-called reset action does not happen very often. Because the physical location of the track is stored in CMOS, the hard disk does not need to move back to track 0 and start again. As soon as the magnetic head is started, the so-called reset action is completed. Unless you restart the computer, the reset action will not happen again
four. The structure of IDE hard disk is similar to that of SCSI hard disk. It's just that the interface bandwidth of the SCSI hard disk is larger than that of the IDE hard disk of the same era, and the SCSI card often has something similar to the CPU to slow down the occupation rate of the main CPU. That's all. That's why Seagate uses the technology of its SCSI hard disk on IDE hard disk
five. The hard disk is read and written in cylindrical sectors. Cylinder is the concentric magnetic track with the same radius of all magnetic surfaces in the whole disk, and dividing each track into several regions is called sector. The hard disk write operation is to fill one sector first, and then write the next sector of the same cylinder. Before a cylinder is completely filled, the head will not move to another track. Therefore, the storage of files on the hard disk is not continuous as most people think (from the user's point of view, it is one, but from the bottom of the operating system, it is not continuous). So no matter how many threads flash get or ED has, the seek of the head is generally not bigger than when you play games and listen to songs. Of course, this situation is just a simple download or upload, but in fact, in this process, who can guarantee that they will not start other software that needs to read and write to the hard disk? Maybe many people like to play games or listen to music while downloading? Not to mention that windows itself needs to read and write virtual memory files frequently. Therefore, whether you download with FG or ED, the torture on the hard disk will not be too severe compared with the usual
six. What's more, it's not easy to turn on too many threads in flash get and it's hard to read and write frequently in ED. First of all, if there are more threads, the CPU occupation rate will be high, and the page change action will be frequent, so the virtual memory will read and write frequently. As for why, anyone who has learned the operating system principles should know, I won't talk about it here. What about ED? Download a file from several people at the same time, and several people are downloading your file at the same time, which is similar to FG multithreading. So the hard disk light flashed. However, today's hard disk has a cache. Instead of writing the data to the hard disk immediately, the data is stored in the cache first, and then written to the hard disk once a certain amount is reached. No matter how it is set in FG, it is written to the cache first. But this process also needs CPU intervention, so the setting time is too short, the CPU occupation rate is also high, so the hard disk light is still flashing, because the virtual file is reading and writing
seven. The hard disk is read and written frequently, and the magnetic head arm moves frequently under the drive of the seek servo motor, but for the machinery, the loss is small. Unless your hard disk itself has mechanical failure, such as arm deformation and so on (the most common failure of parallel procts). The real loss is the head. The changing current will cause its aging, but compared with its life..... It should also be within a reasonable range. Unless the head hits the disk because of the vibration
eight. The most seriously affected by high temperature is the mechanical circuit, especially the circuit board outside the hard disk. The integrated block on it will accelerate the aging under high temperature. So a certain glass hard disk of IBM, though bad, disappeared immediately after using a certain software. No matter how strict the point is, it will be normal to replace a circuit board. That's why.
I'm so tired after typing so many words
in a word, the hard disk will affect its life e to poor environment and improper maintenance, but it is definitely not the fault of the software
flash get, ed or FTP, although they read and write to the hard disk frequently, they are not as harmful to the hard disk as you usually play games or listen to music. To be more clear, their so-called consumption of the hard disk can be ignored. Don't worry about it just because you see the flash of the hard disk light. Otherwise, the servers that provide web services and FTP services will be able to, Their hard disk read and write is so big that it is not common to play games. The hard disk of software is comparable
the hard disk has a parameter called continuous time between failures. It refers to the longest time from the beginning to the failure of the hard disk, the unit is hours, the English abbreviation is MTBF. The MTBF of general hard disk should be at least 30000 or 40000 hours. For details, please refer to the parameter description of the hard disk manufacturer. This is continuous

Instead of writing the data to the hard disk immediately, the data is stored in the cache first, and then written to the hard disk once a certain amount is reached. No matter how it is set in FG, it is written to the cache first. But this process also needs CPU intervention, so the setting time is too short, the CPU occupation rate is also high, so the hard disk light is still flashing, because the virtual file is reading and writing
seven. The hard disk is read and written frequently, and the magnetic head arm moves frequently under the drive of the seek servo motor, but for the machinery, the loss is small. Unless your hard disk itself has mechanical failure, such as arm deformation and so on (the most common failure of parallel procts). The real loss is the head. The changing current will cause its aging, but compared with its life..... It should also be within a reasonable range. Unless the head hits the disk because of the vibration
eight. The most seriously affected by high temperature is the mechanical circuit, especially the circuit board outside the hard disk. The integrated block on it will accelerate the aging under high temperature. So a certain glass hard disk of IBM, though bad, disappeared immediately after using a certain software. No matter how strict the point is, it will be normal to replace a circuit board. That's why.
I'm so tired after typing so many words
in a word, the hard disk will affect its life e to poor environment and improper maintenance, but it is definitely not the fault of the software
flash get, ed or FTP, although they read and write to the hard disk frequently, they are not as harmful to the hard disk as you usually play games or listen to music. To be more clear, their so-called consumption of the hard disk can be ignored. Don't worry about it just because you see the flash of the hard disk light. Otherwise, the servers that provide web services and FTP services will be able to, Their hard disk read and write is so big that it is not common to play games. The hard disk of software is comparable
the hard disk has a parameter called continuous time between failures. It refers to the longest time from the beginning to the failure of the hard disk, the unit is hours, the English abbreviation is MTBF. The MTBF of general hard disk should be at least 30000 or 40000 hours. For details, please refer to the parameter description of the hard disk manufacturer. This is continuous
