anti-theft

to prevent private key leakage

As a friendly format of wallet private key, mnemonics are very convenient for you to backup and import. Because of its plaintext, we do not recommend that it be saved electronically, but copied and kept on physical media. As a al backup, mnemonics and keystore complement each other

and keystores can be stored online, such as cloud disk, or in their own U disk (hardware wallet takes advantage of this), which is relatively safer than online storage. Even if hackers steal your keystores, they can't steal the assets without the password of the keystores, so the password of the keystores is particularly important at this time

loss prevention

the main loss prevention strategy is multiple backup, multiple backup. For example, when backing up a wallet, not only the keystore, but also the mnemonic words and private key should be backed up. This is a multiple backup

2. You are right. Indeed, it will be rolled back. If the transaction is unfortunately packaged on the fork, the transaction is likely to be cancelled after the main chain is synchronized

the reason why we need six confirmations is that it is more difficult to obtain the optimal solution (to prevent single node fraud). One block may also be able to get an optimal solution, and it is basically impossible to get six blocks together. It has nothing to do with bifurcation

3. BSC BTS
is called ABIS port
BTS and MS
is called um port, that is, air interface
there are actually two interfaces between BSC and MSC, because there is also a TC mole, and the two interfaces are ater port and a port respectively.

4. According to the analysis of 360 security center, the campus network blackmail virus was spread by the "eternal blue" hacker weapon leaked by NSA“ "Eternal blue" can remotely attack the 445 port (file sharing) of windows. If the system does not install the Microsoft patch in March this year, it does not need any user operation. As long as it turns on the Internet, "eternal blue" can execute any code in the computer and implant malicious programs such as blackmail virus.

5. 1. Install a computer manager
2, and then use the computer manager toolbox to fix the vulnerability
3. Just use this tool to fix the vulnerability

6.

Don't worry about this at all, because it can't be tampered with

bitcoin is a derivative of blockchain, which naturally has the property of non tampering, so there is no need to worry about bitcoin transaction records being tampered with

7. Keep your key away from the Internet

8. Bitcoin is stored in a bitcoin wallet, which can't be tampered with by quantum computing technology

9. The most important feature of bitcoin is decentralization, which is realized by asymmetric encryption technology and distributed storage. The second feature of bitcoin is that it cannot be tampered with, which is guaranteed by the workload proof mechanism and the longest chain mechanism.
