Security – Is a 24 word seed more secure than a 12 word seed in terms of private key brute force attacks?

In the case of brute force private key, both 12-word seed phrase and 24-word The seed phrase provides the same level of security if it was generated using a strong random number generator.

The reason is that the private key derived from the seed phrase is essentially 256-bit For the Bitcoin protocol, the number (specifically secp256k1 elliptic curve used in Bitcoin). The seed phrase is used to deterministically generate the private key, but the private key itself has a fixed length of 256 bits.

If you use a 12-word seed phrase, the seed phrase is used to generate your private key through a series of cryptographic operations. Similarly, if you use a 24-word seed phrase, the same process is used to generate your private key.

Additional words in the 24-word seed phrase are used to provide additional entropy and increase the number of possible seed phrases. This helps protect against possible crashes. (two different seed phrases that generate the same private key)However, it does not directly affect the security of the private key itself.

to sum up, the security of a private key is determined not by the number of words in the seed phrase, but by the length and randomness of the base bits used to generate it. both 12-word seed phrase and 24-word Number of seed phrases When created correctly, it provides strong security.
