Don’t want it to be a copycat but I find this feature they have interesting and sustainable.
Tranquil has a stONE token which is issued when a ONE token is staked through them. They then spread out this stake to a bunch of validators.
Rewards are compounded which makes the value of the stONE token naturally grows against ONE.
MarsColony has seen some involvement from a couple of validators, like @Intrepid.One_Validat for instance @brother @eugenefinch .
Can we imagine on the long run something similar for MarsColony with an interface where we could delegate some ONE, and be rewarded with an ingame currency?
