Keep in mind that you will need the full blockchain for it to work properly. I have uploaded a copy of the blockchain here (it should contain all blocks up to about 85150). The other thing to keep in mind is that it will take quite some time to process the blockchain the first time you run parse_txs.php. I have uploaded some pre-processed db files here. Extract those files into the db folder before you run parse_txs.php. The explorer doesn't have an API yet but I plan to add one. I think we have a VPS server that we can run the explorer on but I would appreciate it if someone else could also run a Cryptonite block explorer.
