I'm cautiously positive on Citrea (my knowledge is level potato on this though). If BitVM gets reasonable performance on doing the proofs, this model seems quite good and it seems possible to plug this into LN, so all LN infra and wallets can continue working & expanding while we get more "onchain" capacity.
What worries me is the people that funded this work... feels like a bunch of shitcoiners, but I'm happy to be proven wrong.
