The foundation layer needs to be finished. It needs to be protected, and that means the witness selection/retention system really does need a solid overhaul. I know people will scream all day long that what happened on steem can not happen on Hive, it needs to be foolproof. How many dead witness accounts are there? How many are current and up to date? A strong witness system will enable a lot more confidence in those that want to look at working with Hive Block Chain in a layer two system.

I see no problem with trying to protect the foundation layer from spam token, spam smart contracts. Right now there is nothing stopping anyone from building their own Hive Engine style place on Hive. No reason for others to not be able to build NFT type places either. Look at the number of games being built there was no "you can't do that" cause I did coming from you. If I remember correctly over on steem you even tried to help a few.

You have shown people what the second layer can look like how it can function and how valuable it can be.

So witness selection/retention, and resource credit sharing are two of the things I would like to see to help solidify the foundation layer of Hive. Just a Hive users opinion.
