S> Yes, it seems pretty logical to group these two procedures together, since one is a special case of the other. As a side note, I would like to clarify whether the user who commits to one/many private keys can somehow βcheckβ at a later date how many keys he has used? Will this information not be lost if the procedures are merged?
M> It is seen from the bitcoin script, which is shipped (before the output is spent) as a part of the client-validated state.
F> There is a point that is not clear to me in lnpbp-1. In the second point of the specification paragraph it states:
"Compute HMAC-SHA256 of the lnbp1_msg and P, named tweaking factor: f = HMAC_SHA256(s, P)"
However s
is not previously defined, so I guess it refers to the message string of lnbp1_msg
. If so for clarity in this sentence we could put directly lnbp1_msg
instead of s
.
Moreover this could also cause extra confusion in the context of lnpbp-2 where S
is used to indicate the sum of all public keys in a script
