ChainConfig

ChainConfig defines the Ethereum ChainConfig parameters using sdk.Int values instead of big.Int.

NOTE 1: Since empty/uninitialized Ints (i.e with a nil big.Int value) are parsed to zero, we need to manually specify that negative Int values will be considered as nil. See getBlockValue for reference.

NOTE 2: This type is not a configurable Param since the SDK does not allow for validation against a previous stored parameter values or the current block height (retrieved from context). If you want to update the config values, use an software upgrade procedure.
