2. First of all, IFPs is an agreement, and IPFs can't dig. What we call IFPs digging money is actually digging the incentive layer of IFPs, filecoin. Currently, filecoin has not been launched. According to the official reply, it is expected to be in 2019q2 / Q3; After going online, we can gain profits by being a storage miner and searching miner. The prospect of this project is still very big. The main way for miners to benefit is to need enough storage space and bandwidth. At present, there are many deceptive elements in the devices sold on the market, and I have learned a lot about them before. The reliable one is the matrix Z3 of Hangzhou Diancun, which meets the hardware conditions and has enough software development strength support. If you think about it, you can learn more about it.

Interstellar file system
IPFs is a content addressable peer-to-peer hypermedia distribution protocol. IPFs combines the existing successful systems, such as distributed hash table, BitTorrent, version control system git, self certified file system and blockchain, to form a file storage and content distribution network protocol. IPFs is also an open source project
IPFs attributes:
1, permanent, decentralized save and share files
Peer to peer hypermedia: P2P stores all kinds of data3. Versioning: it can trace the modification history of documents
extended data
advantages of IPFs:
1. Content addressing: all content (including links) is uniquely identified by its multi hash check sum
2. Tamper proof: all contents are verified by their checksums. If the data is tampered with or damaged, IPFs will detect the data
3. De rendancy: all objects with identical contents are stored only once
PFS does not require every node to store all the content. The owner of the node can choose the data he wants to maintain freely. Besides backing up his own data, he voluntarily provides services for other concerned content source: network interstellar file system
4. Mining is actually bitcoin every 10 minutes (the current stage) of the bitcoin system, but it is in the encrypted account of the system. The password is encrypted just like that of ordinary banks, but the cracking difficulty is quite high, several orders of magnitude higher than that of ordinary banks. The password is quite complex. Mining is guessing the password, The system will adjust the difficulty of cracking the password according to the computing power of all current mining machines. The difficulty is controlled in that the total computing power can be cracked within "about" 10 minutes. The result is to see which mining team works out the password first. If you guess the password correctly, you will be rewarded if you guess it first, but not if you guess it later
there is also a more vivid explanation: banks issue currency (bitcoin) and ask security companies to escort (mining), and reward the escorts (mining to get bitcoin). The reward is limited. The more escorts, the safer the currency. The more rewards.

6. The story of Edison
Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference<
the story of Edison
one snowy night, Edison's mother suddenly fell ill, and his father rushed to the doctor. The doctor said, "your mother has acute appendicitis and needs an operation.". At that time, there was only oil lamp, but no electric lamp. The light of the oil lamp was very dark, and it would be wrong if you were not careful. Edison suddenly thought of a good way, he took out all the oil lamps at home, and then put a mirror behind the oil lamp to let the doctor finish the operation smoothly. The doctor said, "son, you saved your mother with your wisdom and cleverness." Edison took his mother's hand and said, "Mom, I want to make a night's sun."< One morning in the autumn of 1877, Edison came to the editorial office of a magazine in New York from a place called Merlot. He carefully held a little thing with a strange shape. The little thing has a long metal bar on it, a big wheel on one end and a small handle on the other. Edison swung his hand, then
wrapped a small piece of tin foil in the cylinder, put on a small needle, and sang a baby hypnotic song to the cylinder. After the action, the machine starts to rotate again, and it sings the hypnotic song again word for word. It's not enough to describe the first feeling of those present at that time. People were overjoyed. All the people in the editorial department told each other that Edison had brought a talking monster. In a short period of time, journalists from all the newspapers in the city rushed to see the most novel machine in the world. Once this invention came out, it aroused the rapid and huge fanaticism of the society at that time for several months. Railway special train to visit
view. Many people began to disbelieve this invention, suspecting that he was hiding something that could speak in it to deceive people. The bishop of a church recited a series of special terms in the Bible to the radio at the highest speed. When these terms were repeated from the machine word by word, they believed that there was nothing false about them
this is what happened when the world's first phonograph came out. People in praise, said the inventor Edison is a "demon". In fact, the nickname of "demon" is far from the invention of gramophone, but it accompanies his whole life. Because he has too many inventions. Electric light, telephone, movie, telegraph, power generator, battery, typewriter, magnetite separator, pressure gauge and so on are all his inventions. According to incomplete statistics, from 1869, when he invented the first automatic counting machine, to 1910, he obtained a total of 1328 invention patents. During this period, he had one invention every 11 days. Because of this, it is natural for him to be called "demon"
but where does the real magic of this "demon" come from? He himself said, "one percent inspiration, ninety-nine percent perspiration." Tenacious perseverance and amazing
diligence are his real "magic power"< Thomas Edison was born in 1847 in the state of Warsaw. He only went to primary school for three months. The school teacher said that he was "stupid", and his relatives and friends all called him
that. But his mother didn't believe it. She was his teacher and guided him to read some books. Before he was 12 years old, he had read many difficult books, and his father led him to study Newton's principle. Family ecation and influence, so that he developed a spirit of diligence and amazing perseverance
Edison loved science. When he was very young, he stored hundreds of bottles for various experiments in his cellar and built a small laboratory. He spent all the money he saved on his daily life on chemical supplies and instruments. But this money alone can not meet the needs of the experiment, so he went to the train as a newsboy. He gets on the bus in the morning and goes home after nine o'clock in the evening. After the experiment, he often takes a rest late at night. Later, he found that there was a smoking room in the luggage compartment of the train that was not used, so he moved the test objects in the cellar of his home to this room and insisted on doing chemical experiments. Here, he also learned to use a printer set up here, and was able to record the local news with a telegraph number, and ran a newspaper. The newspaper was so popular that it sold well that he was only twelve years old. One day, the train shakes, the luggage slides down, and one of his phosphorus poles falls to the ground
and the carriage catches fire immediately. The fire was put out by the people who rushed to the scene, but the conctor deafened him and disabled him for life. The conctor also kicked everything in his "four wheel lab" and "travel printing room" under the car< The difficulties and setbacks did not affect Edison's determination to carry out scientific experiments, so he built a laboratory at home. It is common in experiments that clothes are beaten and burned by electricity. Once, his face was burnt out by nitric acid. Even so, he never lost heart. Edison's earliest efforts greatly contributed to his later inventions. However,
like other great inventors, Edison's road was not smooth. He worked as a night telegraph student. Spend a lot of energy in bookstores and libraries. However, e to the loss of
career for several times, I finally had to go to New York to join my friends
Edison came to New York after a lot of hardships. At this time, he didn't even have a penny in his pocket. He was so hungry that he had to ask for some tea, which was his first meal in Newcastle. Here, he found a friend for a long time, but his friend is also unemployed. Edison, who suffered from hunger, was humble and shabby, and could not afford to be seen. Later, he was allowed to stay overnight in a battery room. It happened that a communication machine was set up in the room to release the market price. On the morning of the third day when he arrived, the machine was out of trouble. Because he paid attention to it, he quickly helped others repair the machine and was left behind. Then he found a job. Since then, he has made great efforts to cooperate with others in the reform of the market price communication machine. Soon, he opened a small factory to proce this kind of communication machine, and graally embarked on the road of scientific research<
solid steps
it's not surprising that electric lights are used today. But before 1880, electric light had only its rudiment, which was the most popular arc light at that time. This kind of lamp is connected with two charcoal on the heads of the two poles of the battery. After the battery is electrified, the two poles are touched, and then they are separated, and a flame immediately occurs between the two poles. Because the two carbon poles are horizontal and there is hot air rising in the middle, the flame between the two poles will bend upward slightly, like a bow or arc, so it is called arc lamp. This kind of lamp has many disadvantages: it needs to change the carbon strips constantly; The sound is loud; The lighting effect
is small and easy to damage the eyesight. Dirty air; Another big drawback is that a return current can only light an arc lamp. At that time, some famous scientists, including the inventor of arc lamp, did not always praise this kind of lamp. However, in 1877, Edison began to reform the arc lamp experiment, and proposed to divide the current (that is, one port current points many lamps), and change the arc
light to white light. The experiment should be satisfactory. It is necessary to find a kind of material that can burn to white heat to make filament, and this kind of filament needs to withstand the combustion of heat at 2000 ℃ for 1000 hours
. At the same time, the usage should be simple, can withstand the impact of daily use, and the price should be low, and the on and off of one lamp should not affect the on and off of any other lamp,
keep the relative independence of each lamp. This was a very bold idea at that time, which required great efforts to explore and experiment. Some scientists laugh at him for being a fool and satirize him for "dreaming and boasting". Some other scholars prove that his research is impossible with mathematics.
