Dad: Son, how can I convert a 24 word seed into a 12 word seed (BIP39)? 12 words can be better memorized.
Son: Hi Dad,
Converting a 24 into a 12 word seed is impossible.
According to BIP 39, a mnemonic seed is converted into a binary seed using PBKDF2-SHA-512.
To turn a 24 word seed into a 12 word seed, you'd need to find a 12 word seed that produced the same binary seed, which is believed to be impossible.
Dad: Oh, I see.
It will take me a while to learn all 24 words.
