The first example explorer for Open Source CCE 4.0 is up!
As mentioned before it is a Blakecoin explorer.
http://openblc.cryptocoinexplorer.com/I have a spare VPS I'm not using atm so I might give it a go. How much drive space would one need to run hobonickelsd & CCE 4.0?
The live (Version 3.5) HoboNickels explorer database is running at about 6 GB. The database might be smaller in CCE 4, but at this point I do not have enough information to compare.
