I think most have missed the fact that this native DEX based ecosystem already solves the scaling problem as overall capacity can be increased just by spawning new blockchains. native DEX can then allow tokens to flow between the chains based on market price or 1:1 pegs or pricefeeds.
This whould be a killer, IMO. I hope there would be good documentation on how to do this, so, say, I would be able to create zero-knowledge token, pegged to a local currency and instantly available on DEX.
