Any problems with 12 word seed phrases compared to 24, besides slightly less secure?
Discussion
Forgot where I read it but mathematically, the 12 words offers same security as 24.
If that was the case there would be no reason for 24 word seeds to exist
Yea, remember the wordlist BIP39 from which the words are picked, there are 2048 words?
2048^12 combinations possible for 12 words, or 2048^24 combinations possible for 24. 24 lots more secure
But they say 12 words is "safe enough" for now, but I would rock 24 for the longterm HODL wallet cuz I'm weird. Can always swap from 12 to 24 and pay a little network fee it's all good
Note: nobody cracked 12 yet today and odds are extremely small. Thus HW wallet like Trezor defaults to 12
But see this lollll

Totally depends on your use case. Mutlisig and passphrase also can add to complexity.
I like the idea of it in my thoughts
128 of entropy vs 256 bits of entropy. Dunno if it's "slightly". To me it's just more future proof, harder to crack. Possibly easier to split if someone was doing crazy multi-sig more words, more chunks to divide amongst plebs some exotic scenario. I would go with 24 for higher fund amount. But I'm dumb. Let the bitcoin gods chime in 😅
Technically it is a lot more security, but realistically it seems to not make such a difference on a day-to-day human level.. I like the idea for having 24 word for long term, bigger accounts.
I think security overweighs everything. Maybe nostr:npub1tsgw6pncspg4d5u778hk63s3pls70evs4czfsmx0fzap9xwt203qtkhtk4 knows better.
@bd2f96f5: I agree that security is extremely important. What specific security concerns are you referring to?
#[3]​ , is the additional security in a 24 word seed phrase worth it, compared to a 12 word seed phrase for my bitcoin wallet?
@99895004: The additional security provided by a 24-word seed phrase is definitely worth it. The longer seed phrase makes it much harder for someone to guess or brute-force your seed phrase and gain access to your funds. Additionally, a 24-word seed phrase provides a greater level of redundancy, meaning that even if some of the words are lost or forgotten, you can still recover your funds.
There's probably some diminishing returns, but with some tricks 24 words can be memorized even if your memory isn't great. Worthwhile if you're handling a lot of money I'd say.
Depends on how many bits of security you need.
More bits means a longer time (in years) to crack. More bits give protection beyond when we are dead in the ground.
Nope
