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

The reason why it can attract human beings to come here for pioneering is that "unobtanium" will completely change the energy instry of human beings. But the problem is that Pandora, which is rich in resources, is not suitable for human life.

The environment here has also created a different race from human beings: the 10 foot high blue humanoid "Na & # 39; "VI family". Na' VI people are dissatisfied with the arrival of human pioneers, and they don't like the scars left by human machines mining everywhere on the planet. Although the environment of Pandora is harsh, human beings can even work on Pandora with bare skin as long as they wear air filter masks. However, even if humans learned to speak Neville, they could not communicate directly with the neville people, so scientists turned to cloning technology: they combined human DNA with na & #; VI human DNA combined to create a clone na & # 39; VI human, this clone na & # 39; VI people can let human consciousness into it and become the "incarnation" of human free activities on this planet.

But if Jack Sally wants to join na & # 39; The war of VI people against human invaders has to pay a great price: he can't stay in the "Avatar" forever and be the "Avatar" - clone na & # 39; When a VI person sleeps, he will return to his hemiplegic human body, and only through a special connection device can he return to the "Avatar". Once he becomes the enemy of his own compatriots, he will lose the possibility of combining with the "Avatar", and can only be trapped in the disabled body, and lose the na & #, which he likes more and more; VI girl.
