Database hacked for bitcoin
Publish: 2021-04-25 03:32:58
1. 1. Every server has a database backup, and some of them are backed up on other databases or other mobile hard disks. If hackers attack, they can recover
2. If you don't have a backup, you have to call the police
3. Contacting hackers without permission can't recover data, and they will only sink deeper and deeper
4. Pay attention to more backup and multiple ways in the future, and the daily responsibilities of the administrator should also be managed by someone.

2. bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, similar to Tencent's q-coin, but it has been able to buy real-life goods.

as we all know, the "blackmail virus" is rampant all over the world, and hackers ask the "victims" who are recruited to pay bitcoin. According to the data, the price of bitcoin has skyrocketed by 2.21 million times in the past eight years
for the rise of bitcoin price, the Chinese people must have made their own contribution. After all, bitcoin trading in China once accounted for more than 80% of the global trading volume
However, according to the latest data from the research department of fire coin, Japan accounted for 46.4% of the global bitcoin trading volume last week, followed by the United States, accounting for 26.4%, China ranked third, and the trading volume dropped to 10%. Therefore, if the price of bitcoin exceeds 10000 yuan recently, the contribution of Chinese people should be very small4. Because bitcoin is valuable now
5. Because bitcoin is valuable! In the past year, bitcoin has soared all the way. The highest price of bitcoin has exceeded US $2600, and now the price is US $2475. In the past year, bitcoin has increased by 2.64 times, which is amazing.
6. Camouflage global IP address to attack foreign websites, and then wordy, bitcoin is illegal at home.
7. Bitcoin is used for blackmail because it not only has advantages over other traditional payment instruments, but also is the best choice among other virtual currencies
firstly, bitcoin has certain anonymity, which is convenient for hackers to hide their identities; Secondly, it is not subject to geographical restrictions and can collect money on a global scale
at the same time, bitcoin also has the feature of "decentralization", which allows hackers to automatically process victims' ransom through programs
compared with other digital currencies, bitcoin currently has the largest market share and the best liquidity, so it has become the hacker's choice. This is similar to the logic behind the fact that criminals like to use US dollar cash
bitcoin is a network virtual currency born in 2009. It is also the most frequently used virtual currency in the world
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique. In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
the reason why bitcoin is so popular is that it can be accepted, traded and stored by the whole world after it has currency characteristics. It has formed its unique living environment
there are also bitcoin trading platforms in China. After the accident these days, the price has gone up a little
since bitcoin has no issuer and the theoretical total number is 21 million, it has been circulating on the Internet for all kinds of transactions, and there are great hidden dangers. China's attitude towards its development is serious and cautious. Although it is not forbidden, its supervision is very strong

8. Each of us a citizen, should I start from, take the initiative to conserve electricity, Guan period is able to put Dong Xi Jiang Di refrigerator power consumption of food should be cool down and then Fangru fridge to avoid wasting energy Leng. 2: use less air conditioning. Hot summer, many people are using air conditioning, which is the main factor causing power shortage. I suggest that you use less air conditioning because the air-conditioning too much power, and it will air sick Develop the habit of saving electricity, energy value, energy savings, from ourselves and from now on. Let us all work together, the same as the value of life to cherish each unit of electricity, contribute to saving a power! Every citizen should start from me and take the initiative to save electricity. There are also some ways to save electricity: first, rece the number of times to open the refrigerator, and shorten the opening and closing time, which can rece the power consumption of the refrigerator.

9. Because stand-alone means that you set up a dedicated server on your own computer. This is equivalent to your computer is both a server and a client, server data exchange and background simulation will consume a lot of CPU, so your client on the multiple open high, will card. Because the CPU can't operate
the case of private service is that your computer is a client, and it is connected to other people's servers. Their servers are highly configured, and data exchange and calculation are carried out on their servers. Your computer just sends and receives data, and the CPU can fully afford it. So it's not stuck
specialized high-end servers are expensive, and they are generally rented. It's not easy to open a thousand times service, not only to rent money, but also to spend electricity without downtime.
