Anna Shaleva	6381173293	core: store statesync-related storage items under temp prefix ... State jump should be an atomic operation, we can't modify contract storage items state on-the-fly. Thus, store fresh items under temp prefix and replase the outdated ones after state sync is completed.

Anna Shaleva	3b7807e897	network: request unknown MPT nodes ... In this commit: 1. Request unknown MPT nodes from peers. Note, that StateSync module itself shouldn't be responsible for nodes requests, that's a server duty. 2. Do not request the same node twice, check if it is in storage already. If so, then the only thing remaining is to update refcounter.	2021-09-07 19:43:27 +03:00
Anna Shaleva	6a04880b49	core: collapse completed parts of Billet ... Some kind of marker is needed to check whether node has been collapsed or not. So introduce (HashNode).Collapsed	2021-09-07 19:43:27 +03:00
Anna Shaleva	a22b1caa3e	core: implement MPT Billet structure for MPT restore ... MPT restore process is much simpler then regular MPT maintaining: trie has a fixed structure, we don't need to remove or rebuild MPT nodes. The only thing we should do is to replace Hash nodes to their unhashed counterparts and increment refcount. It's better not to touch the regular MPT code and create a separate structure for this.	2021-09-07 19:43:27 +03:00
