I am assuming minimal changes to commitment transaction structure, essentially swapping out
HTLC for PTLC, so no fast-forward schemes here.
Here are output labels because I get confused so often what things in BOLTs mean:
- (a)
a_o_atx_*Alice-offered "offered PTLC" in Alice's tx - (b)
a_o_btx_*Alice-offered "received PTLC" in Bob's tx - (c)
b_o_atx_*Bob-offered "received PTLC" in Alice's tx - (d)
b_o_btx_*Bob-offered "offered PTLC" in Bob's tx
