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. This is an acceptable rounding error since floating point may cause consensus problems if different floating point unit implementations are involved.

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. Meaning that it can't just be the same as the chain id since the chain id may be changed many times with each successive chain in charge of the same bridge
