Good morning Christian,

This is very interesting indeed!

I have started skimming through the paper.

I am uncertain if the below text is correct?

> Throughout this paper we will use the terms *input script* to refer to `w=
itnessProgram` and `scriptPubKey`, and *output script* to refer to the `wit=
ness` or `scriptSig`.

Figure 2 contains to what looks to me like a `witnessProgram`, `scriptPubKe=
y`, or `redeemScript` but refers to it as an "output script":

>    OP_IF
>        10 OP_CSV
>        2 As Bs 2 OP_CHECKMULTISIGVERIFY
>    OP_ELSE
>        2 Au Bu 2 OP_CHECKMULTISIGVERIFY
>    OP_ENDIF
>
> Figure 2: The output script used by the on-chain update transactions.

Regards,
