OK, so I went through the source code and am quite familiar with the core now, did some improvements to the storage and plan to move the core to python. What I am missing here are technical concerns and not MOANING, so please, if you have some (not the local DNET stuff which ca be replaced .... a f. code-monkey project!!!), the floor is yours!
Indeed there is a lot of room for improvement but going through the source code of other "more important" projects such as ETH, I find it unbelievable, the holes that are there to exploit!
What kind of improvement you did to the storage?
