func (k Keeper) GetCosmosOriginatedERC20(ctx sdk.Context, denom string) (*types.EthAddress, bool)

func (Keeper) GetCurrentValset

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

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 where 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) 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 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

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
