I'm not sure, but personally, I find the bip39 standard confusing, and I don't exactly blame them for not following it
Discussion
They have plans to follow it later. It's a single private key and single public key for now for simplicity
Keychat allows for a nym with nsec and seed phrase, not sure if their seed phrase follows bip39, i suppose it should
Yes just created a nym in keychat, used nsec and restore wallet, boom 💥 in
BIP39 is used to derive BIP85 child key. I think it is the only option if using a single backup and index based derived key sets including BIP85 32bit hex keys used as nsec. It is very convenient if proper key management is required.
I don't understand this condition:
> if using a single backup and index based derived key sets including BIP85 32bit hex keys used as nsec.
But if I could get away with ignoring it, I would only quote this part: "I think it is the only option" and then I would say "it's clearly not the only option because bitcoin core doesn't use bip39."
Sadly, I can't say that without doing an injustice to what you said
It's just a question of convenience. You can obviously use something else but having a seperate key backups for every thing becomes ineffective, especially if you're using steel backups.
Bitcon started off with address-based backups, it doesn't mean it was the most effective approach, it was the reason why folks build better solutions.
