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.
