 # Both parties now blind the PSET. Importantly, the final person to blind must
 # have a combined PSET that has everyone else's blinding data included, so that
 # they can make the blinding factors add up.

-# In the 2-party case this is particularly simple because there is no need to
-# combine anything.
+# The most straightforward way to implement this is to have each party blind
+# the PSET, then pass to the next party, who blinds in-turn. If there are more
+# than 2 parties, then you can have all parties but one blind independently,
+# `combinepsbt` the results, and give this to the final party to blind.
+#
+# In the two-party case these are equivalent.

+# Just for fun, try to have both parties blind independently and combine. This
+# will fail because `combinepsbt` needs there to be at least one remaining
