func (Keeper) GetCurrentValset 

func (k Keeper) GetCurrentValset(ctx sdk.Context) (types.Valset, error)

GetCurrentValset gets powers from the store and normalizes them into an integer percentage with a resolution of uint32 Max meaning a given validators 'gravity power' is computed as Cosmos power for that validator / total cosmos power = x / uint32 Max where x is the voting power on the gravity contract. 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.

'total cosmos power' has an edge case, if a validator has not set their Ethereum key they are not included in the total. If they were control of the bridge could be lost in the following situation.

If we have 100 total power, and 100 total power joins the validator set the new validators hold more than 33% of the bridge power, if we generate and submit a valset and they don't have their eth keys set they can never update the validator set again and the bridge and all its' funds are lost. For this reason we exclude validators with unset eth keys from validator sets

The function is intended to return what the valset would look like if you made one now you should call this function, evaluate if you want to save this new valset, and discard it or save

func (Keeper) GetDelegateKeyByEth 

func (k Keeper) GetDelegateKeyByEth(
	c context.Context,
	req *types.QueryDelegateKeysByEthAddress) (*types.QueryDelegateKeysByEthAddressResponse, error)

func (Keeper) GetDelegateKeyByOrchestrator 

func (k Keeper) GetDelegateKeyByOrchestrator(

func (Keeper) GetDelegateKeyByValidator 

func (k Keeper) GetDelegateKeyByValidator(
	c context.Context,
	req *types.QueryDelegateKeysByValidatorAddress) (*types.QueryDelegateKeysByValidatorAddressResponse, error)

func (Keeper) GetDelegateKeys 

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 delegate 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

func (Keeper) GetEthAddressByValidator 

func (k Keeper) GetEthAddressByValidator(ctx sdk.Context, validator sdk.ValAddress) (ethAddress *types.EthAddress, found bool)

GetEthAddressByValidator returns the eth address for a given gravity validator

func (Keeper) GetGravityID 

func (k Keeper) GetGravityID(ctx sdk.Context) string

GetGravityID returns the GravityID the GravityID is essentially a salt value for bridge signatures, provided each chain running Gravity has a unique ID it won't be possible to play back signatures from one bridge onto another even if they share a validator set.

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

func (k Keeper) GetLastEventNonceByValidator(ctx sdk.Context, validator sdk.ValAddress) uint64

GetLastEventNonceByValidator returns the latest event nonce for a given validator

func (k Keeper) GetLastUnBondingBlockHeight(ctx sdk.Context) uint64

func (Keeper) GetLatestValset 

func (k Keeper) GetLatestValset(ctx sdk.Context) (out *types.Valset)

GetLatestValset returns the latest validator set in store. This is different from the CurrrentValset because this one has been saved and is therefore *the* valset for this nonce. GetCurrentValset shows you what could be, if you chose to save it, this function shows you what is the latest valset that was saved.

func (Keeper) GetLatestValsetNonce

StoreValset is for storing a valiator set at a given height, once this function is called the validator set will be available to the Ethereum Signers (orchestrators) to submit signatures therefore this function will panic if you attempt to overwrite an existing key.
