The next step would be to make some statistics about the node and the Vertcoin blockchain available at vtcnode.ofehr.com - but I am unsure as how to do that. Anyone having experience with that (for Vertcoin or any other Altcoin) and can recommend some software, or do I have to write that from scratch?
iquidus and
bitcoin-abe is the answer, both are the most used blockchain explorer that has high portability to another coin and have good documentation.
