Hi List,

I have a question and if it has been discussed before please just point me
to it and tell me to f off :) . Also, if I am grossly misunderstanding
things please feel free to correct me.

Is there a way to deterministic generate H?

Further explanation:

* With bitcoin addresses we have BIP32 that allows us to generate a Master
Private Key, transform it to a Master Public Key and then use that Master
Public Key to generate a series of addresses.

We can generate addresses without the use of the private keys.

* With LN we generate a random value S and hash it into H and distribute
that and then finally distribute S in order to close the channel.

SO, my question:

Is there a way to deterministic generate H like you can generate addresses
with a Master Public Key without revealing S to the generator and still
being safe to use S to close the channel? (Hopefully I am not just
confused and talking bullshit here)
