What if the smart contract platform(s) disappear?
The proposal induces a very centralized system, to my knowledge all of
existing sidechains whether on bitcoin or ethereum are centralized,
except lightning (if we forget that someone must watch what others are
doing when you are on a trek in Nepal)
Now I don't get why a sidechain should be a blockchain on top on another
one (given also that we can't consider bitcoin or ethereum as
decentralized today, so the path might be long for the sidechains...),
the latest is used to store the final state, the former does not have to
store forever the intermediate states, then it could just use a
decentralized system (not necessarilly blockchain-like) to store the
intermediate states and maybe be a distributed escrow
I know, easy to say, please do it (why not), now the fact that
sidechains claim to be decentralized or that they will be is just
misleading people (that's not the case of your proposal but it does not
say what happens if the platforms go down)

> Smart contracts have traditionally been implemented as part of the consensus rules of some blokchain. Often this means creating a new blockchain, or at least a sidechain to an existing blockchain. This writeup proposes an alternative method without launching a separate blockchain or sidechain, while achieving security similar to federated sidechains and additional benefits to privacy and smart-contract-patching.
