This article mainly introduces "what are the knowledge points of blockchain wallets". In daily operation, I believe that many people have doubts about the knowledge points of blockchain wallets. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts about "what are the knowledge points of blockchain wallets?" Next, please follow the editor to study!

wallet

Many people think that a wallet is just a store of digital assets, which is not quite true. A digital asset is a string of characters or code for distributed accounting on a block chain, while a wallet is actually a management tool for keys (including public keys and private keys). It contains a pair of private keys and public keys, which correspond to each other. The user signs the transaction with the private key, thus proving that the user has the right to output the transaction, and the output transaction information is stored in the block chain, and the public key is used to generate the address. To put it simply, the wallet will have a corresponding address and private key, the address can be publicly shown to others, but the private key is absolutely not, otherwise it will not be secure.

Address

The public key is paired with the private key, the public key is calculated from the private key, and the address is further calculated by the public key. Note, however, that the address is not the public key. When the wallet is created in imToken, a 42-bit hexadecimal hash string starting with 0x is generated, such as 0x7A51Be24D95bb4935dd36eC836CFeDD77aa7b3C5. This string of characters is the wallet address, which is unique and unmodifiable. In other words, the transfer address of all tokens in a wallet is the same. For example, the transfer address of ETH in a wallet is the same as that of EOS. This is different from that on the trading platform, where the transfer address of different tokens is generally different, so be sure to confirm the address before transferring the currency to the trading platform.

Purpose: the wallet address can be used to receive other people's money, and it can also be used as a voucher to transfer money. The address can be made public at will, but the private key must not be made public!

Password

When creating a wallet, you need to set a password that requires no less than 8 characters. For security, the password should be a little more complex. The password can be changed, and there are two ways to change the password: one is to enter the original password, you can change the password directly. Second, if the original password is forgotten, import the wallet with a mnemonic or private key and reset the password at the same time.

Purpose: there are two passwords, one is the payment password when transferring money, the other is the login password when the wallet is imported through keystore.

If in the real world, a bank card corresponds to only one password, after the password is changed, the original password will lose its effect. But in imToken wallets, it is different. A wallet can use different passwords on different mobile phones, independent of each other and independent of each other. For example, setting a password in my mobile wallet, importing the wallet into your phone and setting a new password does not affect the password of my mobile wallet.

Mnemonic words

Mnemonic is another form of private key, mnemonic = bank card number + bank card password, mnemonic = private key. The main purpose is to make users better remember their private keys. After creating a wallet, there will be a backup mnemonic function, select backup mnemonics, enter the password, there will be 12 words, and there is a space between each word. This is a mnemonic. A wallet has only one mnemonic and cannot be modified.

Usage: mnemonic words have the same function as private keys. When importing a wallet, enter mnemonic words and reset a password, you can enter the wallet and have control of the wallet, and you can transfer the tokens from the wallet. Once your mnemonic words are leaked, it is tantamount to running naked.

Note: mnemonic words can only be backed up once, and after backup, they will never be displayed in your wallet again, so it is best to copy them in your notebook during backup.

Private key

The private key is essentially a random number of fixed length. After creating the wallet, enter the password to derive the private key. A wallet has only one private key and cannot be changed. Whoever owns the private key will have the control of the digital currency. Therefore, the private key is very critical, must be well preserved. However, because the private key is too long, the wallet will not be set by the user, but the wallet will generate the private key by itself.

Purpose: in the import wallet, enter the private key and set a password (without entering the original password), you can enter the wallet and have the right to use the wallet, you can transfer the tokens from the wallet.

Keystore

Keystore is not a private key, it is a string of code, commonly found in Ethernet Square wallet, usually after you create Ethernet Square wallet, you will be asked to back up Keystore, choose to back up keystore, enter the password, there will be a large number of characters, this is keystore. The essence of Keystore is the encrypted private key, and Keystore must be used with the wallet password.

Purpose: when importing the wallet, select the official wallet and enter the keystore and password to enter the wallet. It should be noted that this is not the same as importing a wallet with a private key or mnemonic, which can be reset directly without knowing the original password.

At this point, the study of "what are the knowledge points of blockchain wallet" is over. I hope to be able to solve everyone's doubts.
