Woxing intelligent miner
in fact, no matter what the mining friends ask, what attracts them most is the super cost performance of mining machinery. Hummingbird H1 is the first IPFs family miner of starbit, which is equipped with IPFs OS operating system (based on Linux) and supports 20tb hard disk expansion. In terms of hardware, considering the high noise, high power consumption and other disadvantages of traditional mining machine, hummingbird H1 has carried out a comprehensive optimization for the home scene, while ensuring the hardware performance (supporting 20tb expansion), controlling the noise at & lt; 30 dB, close to silence; At the same time, the power consumption of the mining machine has been effectively controlled. The annual electricity charge is about 150 yuan, which greatly reces the investment cost.
multi token adopts sha256 encryption algorithm. In the initial stage, there are 15000 multi token per block, with a total of 6.3 billion. The output will be halved every four years, the target time will be 10 minutes, and the difficulty will be adjusted once every two weeks. Dotcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Unlike most currencies, multi currency does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Multi currency economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the currency value by making a large number of multi token. The design based on cryptography can make the multi token only be transferred or paid by the real owner, which also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between dote and other virtual currencies is that the total amount of dote is very limited and it has a strong scarcity< Second, the characteristics of dote
1. Decentralization: dote is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of security and freedom of dotcoin
2. Global circulation: multi token can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect the currency
3. Global synchronization: since the first day of its birth, dotcoin has been publicized many times around the world, and there is no pre excavation behavior of a company or its founder. In particular, publicity through different channels around the world avoids the possibility that dote is just a pet of a few geeks or that dote is hoarded by a few people in the early stage
4. Exclusive ownership: the private key is required to manipulate the multi token, which can be stored in any storage medium in isolation. No one can get it except the user himself
5. No transaction cost and hidden cost: the exchange of multi currency is almost zero cost, especially in multinational trade, which can save a lot of costs. As a means of payment from a to B, dotcoin has no cumbersome limit and proceres. If you know the other party's multi currency address, you can pay
3. Why dote was born
1. The name of dote, in English, is a trading currency, born out of trading. Because the number of bitcoin is rare, in the application, it is often divided to more than three decimal places, which is extremely inconvenient to use. Therefore, as an effective supplement to the transaction, dotcoin emerges as the times require
2. Bitcoin is the aristocracy of digital currency, which is worthy of storage and collection. Just like gold in ancient times, how many people buy and sell gold coins in their daily life? In ancient times, gold bars and gold coins were used only by nobles and large transactions. It's the same with digital currency, which is worth thousands of bitcoin. When you buy a bottle of coke or a hamburger, you have the same problem. The tot coin, which is similar to the total population of the world, just meets the needs of people's trade. It is like an ancient copper plate, which can buy two sugar gourds or a jin of salt< 4. The universal rule of dote
1. Bitcoin is gold, and dote is copper. Bitcoin is now recognized by all countries in the world. However, the only regret is that Europe, Asia, Africa and Latin America all paid attention to bitcoin after 2011. This is not absolute fairness, although it is not the responsibility of bitcoin developers, Then, it can't be regarded as the real universal
2. Where is the 10.5 million bitcoin going? Especially, what is puzzling is that from 2009 to 20131050 bitcoins have been born, but where is it going? In which deep courtyard, was hidden. Because of the anonymity of bitcoin, we don't know. However, the 10.5 million bitcoins must be recognized in developed countries, especially in the United States. However, will bitcoin be the reserve force used by the Federal Reserve to fight the currency war? This is not known. But we can have more choices, we can have a more universal and fair digital currency to trade. The field of digital currency where a hundred flowers bloom and a hundred schools of thought contend is the healthy field
3. The truly universal digital currency, dote dote, is a digital currency that is released simultaneously and open source all over the world. Whether it is developed countries in Europe and the United States, or poor areas in Asia, Africa and Latin America, dote's public information has been disseminated through different channels. People all over the world are in the same starting line, which is of course more concive to being recognized as a general equivalent
4. Swedish mines and hashing algorithm: we all know the advantages of bitcoin, but what about the disadvantages of bitcoin? The disadvantage of bitcoin is that it is too small because of circulation. The early publicity was not enough. In the early stage, 10.5 million bitcoins were in the hands of very few people
then, if there is a currency that has the advantages of bitcoin and avoids the disadvantages of bitcoin, isn't it a real digital currency? Yes, but it's not that easy. The reason why there are not many new coins with hash algorithm is that hash algorithm is completely open source. This new P2P currency is very fragile and vulnerable to 51 attacks. Any indivial or organization, as long as they control the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. In the early stage, many hash algorithm coins without strength died in this link
dotcoin, the foundation of digital currency initiated by Sweden mine, the largest mine in the world, has been echoed and supported by domestic mine owners, including Greig technology. It is equivalent to 35% of bitcoin's current network computing power, and it is the first time in the world to escort a new coin. At the same time, the largest world technology center of digital currency will be established in Europe. This center is a pure technology third-party organization, which is not under the jurisdiction of any country, government or company. It is independent of digital currencies such as dotcoin and bitcoin, but it also provides technical protection.
One day in June 1752, in the suburbs of Philadelphia, the United States, there were dark clouds, lightning and thunder. On a wide grassland, there were two people, an old man and a young man, flying kites there with great interest. All of a sudden, a flash of lightning split the clouds and drew the word "Zhi" in the sky. Then there was a thunder and the rain fell down. I saw the old man shouting: "William, stand in the thatched cottage over there and tighten the kite string."
at this time, the lightning lights up one by one, and the thunder goes up one by one. Suddenly William yelled, "Dad, look!" The old man looked in the direction of his son's finger, and saw that the taut hemp rope, which was originally smooth, suddenly became angry, and the fine fibers stood up one by one. He exclaimed happily, "the sky is shining!" As he told his son to be careful, he slowly approached the copper key on the hemp rope with his hand
suddenly, he fell to the ground as if he had been pushed by someone, numb all over. Regardless of the pain, he got up from the ground and connected the Leiden bottle to the copper key. There is electricity in this Leiden bottle, and it also emits electric sparks. It turns out that sky electricity and earth electricity are the same
he and his son took Leiden bottle home as if they were treasures
it was Franklin and his son William who captured tiandian. Franklin is not only a great scientist, but also an outstanding statesman and diplomat. He is one of the founders of the declaration of independence and the first American ambassador to foreign countries
ring his study in Alexandria, he often went for a walk by the Nile River. In the dry season, he saw farmers struggling to lift water from the Nile River bucket by bucket to irrigate the land. He created a kind of screw water extractor to take water from the river through the rotation of the screw, which saved farmers a lot of effort. It is not only used today, but also the original prototype of all the screw propellers used in water and air
When he was a child, Pavlov and his younger brother g a pit for planting apple trees. The pit had already been g. When his father saw it, he said it was not in the right place and g it again. The younger brother put down his shovel and gave up, but Pavlov g up again. He didn't care about the blood blisters on his hands until he g the hole and planted the apple treelater, Pavlov became a physiologist and spent all his time in the laboratory studying the conditioned response of dogs He often used his salary to buy experimental dogs. When dissecting a dog, it takes four or five hours. He counted the dog's saliva from the glass tube very carefully and recorded it in detail in his notebook. After counting for a while, a new assistant felt monotonous and tired But Pavlov solemnly said to him: & quot; If science needs it, count ten or twenty years& quot; At the age of 87, Pavlov developed hepatitis and then pneumonia, but he was still doing & quot; The drudgery of science;. He also regretted that he, as a scientist, did not fully fulfill his obligations to human beings Radar
in the January 1947 issue of the British Journal endeavor, a scientist published a very funny text to explain to us how bats guide their flight in the dark. No matter how dark or narrow, they never hit a wall. What's the reason? How does it know if there are obstacles ahead
two American biologists, Griffin and Garang Bao, have proved in 1940 that bats can avoid collision by using a natural radar, but it is sound wave instead of electromagnetic wave, which is completely similar in principle. A very high frequency sound wave is emitted from the bat's mouth, which is beyond the range of human hearing
the two scientists used a special electric equipment to record the high-frequency sound waves emitted by bats while they were flying. When the sound wave touches the wall, it will turn back. Its eardrum can distinguish the distance between the obstacles and fly in the right direction. Bats transmit sound waves in a very short time and in a very regular way, just like radar
and each bat has its own natural frequency, so that bats can distinguish their own voice without disturbance. For this reason, when a bat flies, it often opens its mouth. If you close its mouth, it will lose its command function. If you close its ears, it will hit the wall and cannot fly. This funny experiment revealed its secret
Nobel's father is a very talented inventor, devoted to chemical research, especially to the study of explosives. Influenced by his father, Nobel showed a strong and brave character from childhood. He often went to experiment with his father. With his father's years of experience in explosive research, his interest soon turned to applied chemistry. He began to study nitroglycerin this is a hard journey full of danger and sacrifice. Death was with him all the time. An explosion occurred ring an explosive experiment, and the laboratory was blown up without a trace. All five assistants died, even his brother. This amazing explosion made Nobel's father suffer a very heavy blow and died soon
out of fear, his neighbors sued the government one after another. Since then, the government has not allowed Nobel to carry out experiments in the city. But Nobel persevered. He moved the laboratory to a boat in a suburban Lake to continue the experiment
after a long period of research, he finally found a very easy to cause explosion material - Mercury fulminate. He used mercury fulminate to make explosive detonator, and successfully solved the problem of explosive detonation. This is the invention of detonator. It is a great breakthrough on the road of Nobel science
