12 words is 3 minutes to crack, goodbye bitcorn

Going through 2^128 different possibilities in 3 minutes would mean you have a magical computer that can go through 1,890,000,000,000,000,000,000,000,000,000,000,000 possibilities per second.

Please point me to such a computer (and ideally an Amazon link, so I can purchase it and become a billionaire)

There is very small pool of keys, if you pay attention when you generate mnemonic, hardware wallets just give you same words,way less than 2024. Any gpu farm will crack it in no time. Those 0000 possibilities just exist in theory, in reality your btc will gone in no time

If you use multisig 12 words makes even more sense.

With this way of storing a seed: https://seedxor.com/ I would guess 24 words would make more sense although I don't know how easy it is to brute-force 6 words and its order. So let's say one part has been discovered, I would be more confident it the other part total was 12 words instead of 6.

That being said I use multisig so I don't have one but multiple seeds. Also thank you for the article it was insightful.

SeedXOR would be just fine with 12 words as I understand it, but seed splitting (a non-recommended but somtimes used backup approach) would definitely benefit from 24 word seeds.

But definitely don't recommend seed splitting, and SeedXOR is almost always a bad idea as well as it multiplies the single points of failure (if you lose any part of the XOR'd seed you lose all funds).

A standard is just the recommended approach, not a hard rule that everyone has to follow! Even on Passport we will default to 12 words but will always allow users to do a 24 word seed if they so wish.

More about defaults and best practices than enforcing anything specific :)
