The hybrid-plasma stuff is really underexplored imo!

could expand on those 'complicated applications' that requires validium over plasma?

building degencast.wtf /degencast . ex-bitmain, binance

Plasma's security model fundamentally requires each object to be mapped to an "owner", who must be actively involved in making transfers and who is responsible for ensuring data validity for that object.

Many apps fail this criterion, eg. who owns Uniswap?

Does progress made on fraud proof translate to plasma?

Plasma can definitely be made significantly better by heavily using validity proofs (aka SNARKs)

I thought generalised state channel (counterfactual team) and plasma folks ended creating optimism? If they time travel back, could they make plasma evm work?
