Maybe, you can outline the following issues:
1) What is the purpose of the blockchain tree?
2) What is the root supposed to be?
3) Why focusing on the hosts for providing storage?
+1, would like to hear from Dev on this one.
1)distributed storage,eliminate waiting time for updated data and search.
2)master chain/parent node.
3)here,host=Acc/node.
Maybe, I expressed myself not well enough. Let me clarify.
1) I see, that trees could help here. Why exactly this type of tree? There are many other types of tree(-like) structure?
2.0) Node = Blockchain?
2.1) So, StorageCoin will not only use 1 parallel Nxt blockchain but many?
2.2) Each child node needs to implement the master/slave protocol?
2.3) How deep will that tree structure supposed to be? Will is build up dynamically?
3) Err, wait. Account != Node. Node = physical device; Account = virtual entity. What is a host? I cannot be both.
1)it's just a choice.
2.0) No.
2.1)many.
2.2)Yes.
2.3)depending on the storage volume dynamically.
3)"forging" account=node.
