This allows us to only use integer division which produces a known rounding error from truncation equal to the ratio of the validators Cosmos power / total cosmos power ratio, leaving us at uint32 Max - 1 total voting power.

The lifecycle of the GravityID is that it is set in the Genesis file read from the live chain for the contract deployment, once a Gravity contract is deployed the GravityID CAN NOT BE CHANGED.
