DATABASES
* Database operations have to be optimized 
    - in terms of not repeating too often 
    - Save changes only when all business logic is approved, since we are working with multiple databases currently 
* Too much of repitition in database operations right now 
* Database model classes, for SQL alchemy, have to be optimized ie. base classes for tokenswap and one-time-event totally different right now 
* Make all database operations to follow SQLAlchemy, no direct SQL commands 
* Remove all position based queries 

PROGRAM STRUCTURE 
* Optimize overall program structure 

NEW FEATURES 
* Rollback feature 
* When processing blocks from the websocket API, check the blockheight of the new block vs the latest block in the database | this is to make sure none of the transactions go missing


-----
processBlocks 

* find the last scanned block in the database 
* find the latest block at the API 
* for loop for lastscannedblock to latestblock 
* processEach transaction based on business logic 
* Update system.db to reflect currently scanned block as the latest block 

* Check for local smart contract triggers 
* Check if any token swap contract deposits have to be returned
