On-chain scaling to potentially ~500 tx/sec through mass tx validation

Oh, I see, the main difference is that L2 engine publishes all the data (all transactions) on the chain (just like in this proposal and in roll_up), while Plasma keeps most of the data off-chain, right?

Yep! L2 execution engines only put execution off-chain and keep data on-chain, Plasma, channels and related systems try to put both execution and data off-chain.
