the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography 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 value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
extended data:
transaction method
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. There are a lot of bitcoin addresses available
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which is used to record how much bitcoin is stored in the address. You can generate bitcoin address to store bitcoin at will. When each bitcoin address is generated, a corresponding private key of the address will be generated
this private key can prove ownership of the bitcoin at the address. The bitcoin address can be simply understood as the bank card number, and the private key of the address can be understood as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep the address and private key when using bitcoin wallet

nowadays, counterfeiters can't be prevented by any means. Today, the director will teach you ten tips to distinguish the true and false Maotai
the first move: look at the logo
there are the following three logos on the front of Pu Mao packing box. The real wine has clear logo, uniform color and careful workmanship; The label of fake wine is crude
note: there is only one five-star or Feitian label for non 500ml, non Pu Mao and old wine
the second move: look at the seal
the middle seam of the original Maotai seal is wide and there are obvious extrusion marks, which is the original packaging process
if there is no extrusion mark in the middle of the seal, or the mark is very shallow, it is fake wine
the third move: look at the logistics code
the ocean mark of the logistics code of the new pumao outer container is right at the top of the word "Mao". If there is deviation or the position is not right, it is fake wine
note: the ocean logo of laomaotai is on the left side of the logistics code, which is not applicable
the fourth move: look at the organic code
most low imitation wines use the computer default font, while authentic procts will have special fonts
in addition, special attention should be paid to the characteristics of the number "7". The number "7" here is straight for authentic Maotai liquor, while the false number "7" will be a little curved, commonly known as "Da 7"
the fifth move: look at the red ribbon
the ribbon on the real wine bottle body is vertical and straight. Since 2004, there are Arabic letters 1, 2, 3, 4, 5... On the ribbon in Maotai, which is very secret, representing the number of the assembly line staff of the batch proction team, but not on the outside ribbon
the sixth move: look at the rubber cap
the fake Maotai rubber cap is flat and has no sense of hierarchy; The real rubber cap has a three-dimensional pattern
the seventh move: look at Feitian trademark
zhenmaotai has fine lines, pure ink and bright color; The false Maotai Feitian trademark has rough printing lines and dark colors
from 2003 to 2004, the eyes and mouth of the flying fairies were closed, which became the closed eyes and closed mouth flying fairies
since 2004, Feitian girl took off her "cassock" and didn't wear it until 2012
the fairy on the right has three red pearls on her head, four red pearl necklaces on her neck, and four red pearls on her left
it is usually difficult to make fake words on fairy feet and at the bottom of the trademark
the word "Zhu" registered in Feitian trademark after 2000 is false if the main point is crooked
special attention: A is closed, B is the background color, and the two places are often adjusted in different years
the eighth move: look at the small food label
in the small food label of five star Maotai from 1990 to 1994, the column of net content is 500ml, M is lowercase, l is uppercase
the ninth move: look at the "Maotai" inkjet code
the inkjet code of Maotai liquor should be one bottle, not repeated, and the section number should be five. If there are special sections such as 0737 and 0747, they are smuggled back from abroad
since June 2001, there has been a black spot between the "Maotai" inkjet codes on the bottle cap< However, since February 2004, the black spots between "Maotai" inkjet codes have obviously moved up
the tenth move: Maotai NFC verification
the simplest and most convenient way is to use the mobile phone with NFC function, download the official app of Maotai Co., Ltd., and put the mobile phone close to the top of Maotai bottle cap to obtain the relevant proct information
note: the NFC identification function was only introced in 2013
the above is the constant upgrading of Maotai in the fight against counterfeiting, and the detailed characteristics of Maotai in different periods
there are those who collect old Maotai at home. Try to check it. The corresponding year and batch can be judged to a great extent by multiple verification of the above details
feel that Moutai and Langjiu are good, and those who drink Luzhou Baijiu Baijiu feel that Wuliangye is good. It's all a matter of habit
is a strong flavor Baijiu variety, and compared with Maotai Baijiu liquor, it is much larger. Therefore, for the number of drinkers, Wuliangye may be more likely to drink. P>
Moutai wine is proced in a year, the starch in the food is fermented continuously, and after many times cooking, alcohol and other organic substances are slowly pushed out, which is the biggest difference between Moutai and other jiu. p>
