BIP32 mnemonics are closely related to the BIP32 standard and the BIP39 standard. BIP32 defines the standard for hierarchical deterministic wallets (HD Wallets), which allows a series of child private keys and child public keys to be generated from a master private key (or seed). BIP39 is designed to solve the need for mnemonics by randomly generating a set of easy-to-remember words as a representation of the seed, which are called mnemonics.
The concept of BIP32 mnemonics
The BIP32 mnemonic is actually a set of words generated under the BIP39 standard to represent the seed required by BIP32. This set of words is usually 12 to 24, and can be English words, Chinese words, or words in other languages, depending on the implementation of the wallet and the user's settings. The main purpose of the mnemonic is to facilitate users to remember and back up wallet seeds so that they can restore the wallet when needed.
BIP32 mnemonic generation process
BIP32 mnemonic generation process usually follows the BIP39 standard, and the general steps are as follows:
1. Generate random number: First generate a 128 to 256-bit random number as entropy, and the number of bits of this random number must be a multiple of 32.
2. Add check digit: Perform SHA256 hash operation on the random number, and take the first N bits of the hash value (N=number of random bits/32) as the check digit, and then add it to the end of the random number.
3. Group and search for mnemonics: Divide the random number with the check digit into groups of 11 bits (because each English word can represent approximately 11 bits of binary numbers), and use these numbers to search the predefined mnemonic dictionary to find the corresponding words.
4. Combine mnemonics: Combine the found words in order to form the final mnemonic sequence.
The role of BIP32 mnemonics
BIP32 mnemonics play a vital role in cryptocurrency wallets. Their main functions include:
1. Backing up wallets: Users can back up their wallets through mnemonics. Even if the wallet software or device is lost, the wallet and the assets in it can be restored through mnemonics.
2. Recovering wallets: When needed, users can use mnemonics to restore wallets in wallet software that supports BIP32 and BIP39 standards.
3. Enhanced security: Since mnemonics are a set of easy-to-remember words, they are easier to remember and store than randomly generated seeds, but at the same time, users are required to keep them properly to avoid leaking them to others.
Precautions
BIP32 mnemonics are highly sensitive and should be kept properly to avoid leaking them to anyone.
When using mnemonics to restore your wallet, make sure to use the same wallet software or device as when you generated the mnemonics, and follow the instructions of the software.
If possible, it is recommended to record the mnemonics on a secure physical medium (such as a paper mnemonic card) and store them in a safe place. At the same time, you can also consider using encryption to protect the mnemonic.
