CTV+CSFS: Can we reach consensus on a first step towards covenants?

[reardencode]

On not ignoring the importance of script cost for contested settlement:

@ariard

Note this concern on marginal channel or off-chain payment is something that very likely affects Ark too. It’s even hard to compare the cost of a LN chan marginal payment vs the cost of a Ark marginal payment, as with ARK you have an ASP and you have to come with some probabilistic estimations for the interactivity of the ASP.

I’ve made a comparison of many alternatives for developing eltoo. Briefly, APO+CTV+standardized_annex is the most efficient of known alternatives. Compared to this:

Method	uncontested	once contested
LNHANCE	+8vB	+16vB
@instagibbs APO+annex	+16vB	+32vB
CTV+CSFS	+58vB	+109vB

As in other protocols CTV consistently reduces cost and sigops even when used with other mechanisms.
