Hi Antoine,
Thank you for the effort you've put towards this. I generally agree that a
smooth functioning Lightning Network is of greater importance than advanced
contracting capabilities. However, as I dive deeper into some of the more
ambitious goals for LN development I am learning that a great deal of
complexity of some current lightning (LN) proposals can be handily
discharged with CTV. While I am not intimately familiar with all of the
other covenant schemes to the same level of technical proficiency, I have a
suspicion that a number of them, if not all of them, are capable of
discharging the same flavor and amount of complexity as well. Others should
chime in if they can confirm this claim.
I have been publicly on the record as supporting the addition of some
covenant scheme into Bitcoin for some time and have long held on
theoretical grounds that the addition of such a mechanism is both necessary
and inevitable if Bitcoin is to survive in the long term. However, as I've
started to work more directly with the Lightning protocol, these
theoretical and purely logical arguments became far more concrete and
immediately beneficial.
I say this primarily to challenge the idea that covenants are a distraction
from lightning development. It may very well be that your areas of focus on
LN preclude you from splitting your attention and none of this email should
be interpreted as a criticism of you applying your efforts in the highest
leverage manner you can manage. That said, I don't want observers of this
thread to walk away with the impression that they are two independent
efforts as covenants can significantly contribute to LN's maturity. When
and how should they be prioritized? Unfortunately I don't feel able to
comment on that at this time. All I know is that Lightning would almost
certainly benefit substantially from having a covenant primitive.
Cheers,
Keags
