 Charging commission on Atom provisions while also allowing for Atom-provisions
 to be auto-bonded (distributed directly to the validators bonded stake) is
 problematic within BPoS. Fundamentally, these two mechanisms are mutually
-exclusive. If there are both commissions and auto-bonding on the staking token,
-the amount of staking tokens each validator and delegator has would change each
-block, so we would have to iterate through all of them.

 In conclusion, we can only have Atom commission and unbonded atoms
 provisions or bonded atom provisions with no Atom commission, and we elect to
