Hey Tom,
Thank you for posting this. Could you put together a chart with some
size numbers so we can get a picture of how strong this compression is?
I understand that because this is targeted at stego/satellite
applications where the user is expected to "shape" their transaction,
that you won't get great numbers if you just look at the historical
chain or try to analyze "average" transactions. But it would be great to
post a chart with uncompressed/compressed sizes for "optimum"
transactions. At the very least, a 2-in-2-out wpkh transaction, and a
2-in-2-out Taproot transaction.
Since the scheme includes explicit support for p2sh-wpkh and p2pkh it
would also be great to see numbers for those, though they're less common
and less interesting.
Cheers
Andrew
