Is it necessary to keep the private key after keeping the mnemonic phrase?
How to use a mnemonic phrase to recover multiple wallet addresses?
#助借词 #私钥 Mnemonic phrase, in the field of cryptocurrency, usually refers to a group of words that can be used to recover a wallet. A mnemonic phrase can recover multiple private keys because it is generated according to a certain algorithm, which can derive an infinite number of private keys from the mnemonic phrase.
In Bitcoin and many other cryptocurrency systems, a technology called Hierarchical Deterministic Wallet (HD Wallet) is used. This wallet uses a single mnemonic phrase (usually consisting of 12, 18 or 24 words) as a seed, and then a series of private and public key pairs can be generated through this seed. This process is deterministic, which means that as long as there is a mnemonic phrase, the same series of private keys can be repeatedly generated.
In this way, users only need to remember one mnemonic phrase to control and recover all addresses and corresponding private keys in the wallet. The recovery process is generally:
Select the option to restore the wallet through the wallet software. Enter your mnemonic. The wallet software uses the mnemonic to generate a seed, and then derives a series of private keys from this seed. Using these private keys, the wallet software can find all the public keys and addresses generated by these private keys, and check all transaction records associated with these addresses on the blockchain.
Please make sure to restore your wallet in a safe environment, because once the mnemonic is leaked, it may result in the loss of funds. In addition, different wallets may use different derivation paths. If there is a problem during the recovery process, you need to check whether the correct path is used.
