✨ Description

Over time, RollbackSynchronizer has received many features, and it has slowly become a God class.

Goals

• Extract history logic to HistoryBuffer #385
  • History should be represented by a separate class
  • Limit defaults to history limit
  • Implements get, set, and trim
• Extract data transmission approaches
  • Extract redundant transmission
  • Extract full state transmission
  • Extract diff state transmission
• Extract node simulation logic from RollbackSynchronizer
• StateSynchronizer to support diff states #475
• Replace property names with indexes in state sync #159
• Attach version tags to property indexes #485

Notes

• RollbackSynchronizer uses three methods of transmission. Each is to be extracted in a reusable way.
  • This can be internal nodes that are added with the node itself, and handle their own RPCs
