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.

func (k Keeper) GetDelegateKeys(ctx sdk.Context) []*types.MsgSetOrchestratorAddress

GetDelegateKeys iterates both the EthAddress and Orchestrator address indexes to produce a vector of MsgSetOrchestratorAddress entires containing all the delgate keys for state export / import. This may seem at first glance to be excessively complicated, why not combine the EthAddress and Orchestrator address indexes and simply iterate one thing? The answer is that even though we set the Eth and Orchestrator address in the same place we use them differently we always go from Orchestrator address to Validator address and from validator address to Ethereum address we want to keep looking up the validator address for various reasons, so a direct Orchestrator to Ethereum address mapping will mean having to keep two of the same data around just to provide lookups.

For the time being this will serve

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
