strategies.
On mobile devices we might not want to load all transfers history
to avoid high internet traffic consumption or to save some space.
On desktop we will load all transfers in background.
- Moved current fetching transfers implementation to
OnDemandFetchStrategy
- Implemented QueuedAtomicGroup to cache outgoing commands above a
threshold
- Refactored some type names, methods for better clarity:
- LastKnownBlock name was misused
- Block renamed to BlockDAO to clarify what it does and avoid
confusion with geth Block type
- Cleanup - removed unused parameters and types' members
- Changed tests to use in memory DB for speedup
- Added more logging and comments
