1. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most 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 nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. 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. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items< On February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency.

2. < / UL >
At present, there is no comprehensive unlocking method. Unfortunately, Windows users are attacked by wana series blackmail virus (bitcoin virus). The current solutions are as follows: (never pay ransom in any case. There is a lot of evidence that even if ransom files are paid, they cannot be decrypted.) < UL >
Windows users can completely eliminate wanacry blackmail virus on devices by formatting all hard disks The encrypted files in other hard disks cannot be unlocked by simply performing system reload.)
indivial users can contact domestic and foreign security manufacturers, such as Qihoo 360, Jinshan drug bully, Kaspersky, mcfel, Tencent security manager and other security centers for assistance in recovering important data
use the file recovery tool to recover. Users who have been infected with the virus can use the computer manager - file recovery tool for file recovery, with a certain probability of recovering your documents
note: we will continue to pay attention to the handling methods of relevant security manufacturers and wait for a more superior perfect unlocking scheme
3. Remember to install the latest version of the genuine patch to update from time to time
4. Because the cost of encryption is much less than decryption,
suppose that a supercomputer can violently try 1 billion passwords in one second by setting a password with numbers and uppercase and lowercase letters (a total of 62 characters), then:
it takes 1 second to crack 5-digit passwords (62 ^ 5 = 920 million),
it takes 62 seconds to crack 6-digit passwords,
it takes 1 hour to crack 7-digit passwords,
it takes 2.5 days to crack 8-digit passwords,
it takes half a year to crack 9-digit passwords,
it takes 100000 years to decipher 12 (more than the history of human civilization),
it takes 24.3 billion years to decipher 15 (more than the age of the universe)
the 15 bit password takes a few seconds to input more than the 5-bit password, but the decryption cost is almost impossible
even if the quantum computer can increase the cracking speed by 100 million times, it will only offset 27 bits of the 256 bit private key length of bitcoin (2 ^ 27 = 130 million). Even if extraterrestrials appear and the cracking speed is increased by 100 million times for several times in a row (each time the length of the private key is offset by 27 bits), bitcoin can simply upgrade the length of the private key to 512 bits.

5. mining software refers to bitcoin mining,
the general process is to use the computer's CPU and / or image processor to calculate bitcoin information
for Internet cafes and users, it will greatly rece computer resources:
program operation is very slow
crash
blue screen
and so on

6. As long as you fail to repay after the repayment date, you will be recorded as overe, which will generate penalty interest. The overe record will have an impact on your future loan processing in Yixin, and may be included in the credit reference system. It is suggested that you form the habit of repayment on time and protect your personal credit records.
