This is a task for optimizing the backend and db migration of a blockchain explorer web-based application.

You will find complete code repository + instructions on how to fire up the web app : [login to view URL]

The current DB architecture is inefficient and upon stress testing with thousands of transactions within a single block, the explorer starts to lag.

The explorer backend is Node.js which is connected to a blockchain node. The Explorer pulls the data from the blockchain node, processes it and then stores it in its centralized db. It also displays the information on the front end (you can check a live version of the explorer : [login to view URL])

Please provide your reasonable bid only if you have strong experience in DB restructuring and performance optimization.
