"Blockchain as a Wallet" approach as a way to convert Bitshares into a sidechain

Thanks for the efforts, but no need to start a new post imo.
We already discussed much in

Key sharing is a no go.

I hope, that concept of sidechain already took your attention. It seems that there are numerous of ways to implement that, but none of them is significantly better than other. I would like to introduce my idea of sidechain implementation. I am sure that it is not perfect. To be honest I will be surprised if nobody be able find a "no go" security reason for this approach because I am not an expert.

Nevertheless, I decided to spent some time to describe my idea in details. Maybe this will build some new perspective and will help figure out even better solution.
