Minimal Viable Plasma

Whats the denial of service concern ?

You could snipe every attempted submission of a state root by submitting a burn request with a higher gas price. (You could probably avoid this problem by giving the operator a multi-block grace period to respond to a burn request.)

If there is an unavailable block, you can create a complaint on the blockchain, and ask the operator to post the block to the blockchain.

This would have griefing problems that as far as we know are probably intractable (see https://www.youtube.com/watch?v=OJT_fR7wexw).

Or you can use an outside storage network like filecoin, and then, to satisfy a complaint, the operator will need a proof of publishing this block on an outside network.

Generally speaking, if you assume that a solution is in place for assuring data availability, you can do much more powerful things, but it isn’t Plasma anymore.
