I was thinking about the sidechain for a while now...
It would be interesting to list Karmashares IPOCOS in some kind of system similar to Nxt or Bts.
Maybe proof of burn with a limited time frame will do the trick!
Or merge mining, crediting the already owners of karma with a fixed amount.
proof of burn would reduce the problem of too many coins in circulation.
so I am all for it.
