ELI5 Seedphrase Cryptography (lemmy.ml)

Hi, could some one explain how are seedphrases considered to be super secure? If it’s just a random string of words from a well-known list of words, what stops someone with a simple python script generating random phrases and trying to open wallets with them?

Thanks for all the answers, Im just going through them quickly now, so quick question, if I understand it correctly, then, knowing seedphrases are from a well known list, all lower case words, doesn’t it make it less safe then? Since attacker knows whats behind the hash? Wouldn’t making it all random instead of using wellknown list more secure?

Yes, it's less secure if they know it's from a list, and which list.

If they don't know that, they have to treat it like a completely random password, which is a lot slower to crack.
