but the project involves running these 3 clients and loading the data into a DB. but by the looks of it , it seems a lost cause, considering the volume !
I've never run an ether node either, but i think you need geth

But yeah, if you're going to parse the full BTC, BCH and ETH blockchain and insert the data into a relational database, you'll need loads and loads of processing power and fast storage (and a lot of it).
thanks a lot again !
i am planning to use AWS and i guess it will give me the required processing power but it is going to be very costly i guess !
