Maybe we need to add states for data

[Daryl-L]

Data doesn't exists when being loaded from block chain is too weird to understand for freash developers. I think we need to provide some states to distinguish. I think maybe like as follow.

enum LoadingStates {
  Fresh = 0;
  Loading;
  Loaded;
  NotExist;
}

Do you mean for the first load of the model, we'd wait for some time then the data would be okay?
It's a good idea to tell the developer the model sync status, and it will be better to add a variable for the store model that stores the current sync block number.

Yes, that's what I mean~
