Hi Joost,
Out of curiosity, what features and benefits are available today? I
know Greg Sanders wants to use annex data with LN-Symmetry[1], but
that's dependent on a soft fork of SIGHASH_ANYPREVOUT. I also heard you
mention that it could allow putting arbitrary data into a witness
without having to commit to that data beforehand, but that would only
increase the efficiency of witness stuffing like ordinal inscriptions by
only 0.4% (~2 bytes saved per 520 bytes pushed) and it'd still be
required to create an output in order to spend it.
Is there some other way to use the annex today that would be beneficial
to users of Bitcoin?
-Dave
