Dev you should remove the Checkpoints from the Source. I doubt you have precalculated 30000 blocks already
Set the First Checkpoint to the genesis hash. I can create a Pull request at github if that is easier for you
In heavycoin . the first 100 blocks rewards are used to do IPO.We don't wanna do IPO.so the first 80000 TEC was wasted.No one own it.and checkpoints.I really wanna change it.but now.I am setting block explorer.maybe later?
