this is pretty clever, the computational complexity seems like it can get extremely high though. From my understanding the nice thing is you only need to go through that complexity if you want to claim back the liquidity
might not understand how ark works, but is the liquidity matter addressed with this augmentation?
from reading through, this appears to help solely in the case of users wanting to forcibly exit
if they don't forcibly exit, then server still has funds allocated to the VTXO output until expiry

before the ASP could only claim back liquidity after 4 weeks and the user could "force close" and get their money back at any time.
The latter half is still true, user can get their money back at any time, but now he ASP doesn't need to wait 4 weeks

reading the post once again, the complexity with the design appears unavoidable. for each round, the users that wish to participate need to verify that their revocation secret was properly added to the new tree. such an invariant requires that the operator reveal all leaves to each and every user to prove that the operator is unable to abscond with the funds. if you do the math, this can quickly get to GBs or even TBs of information, which doesn't seem feasible at all. even more so if a zero knowledge proof is to be used in place.
