func GetBlacksFrom(ctx *CallContext) ([]common.Address, error)

GetBlacksFrom return the access tx-from list

func GetBlacksTo 

func GetBlacksTo(ctx *CallContext) ([]common.Address, error)

GetBlacksTo return access tx-to list

func GetPassedProposalCount 

func GetPassedProposalCount(ctx *CallContext) (uint32, error)

GetPassedProposalCount returns passed proposal count

func GetRuleByIndex 

func GetRuleByIndex(ctx *CallContext, idx uint32) (common.Hash, int, common.AddressCheckType, error)

GetRuleByIndex return event log rules

func GetRulesLen 

func GetRulesLen(ctx *CallContext) (uint32, error)

GetRulesLen return event log rules length

func GetTopValidators 

func GetTopValidators(ctx *CallContext) ([]common.Address, error)

GetTopValidators return the result of calling method `getTopValidators` in Staking contract

func IsDeveloperVerificationEnabled 

func IsDeveloperVerificationEnabled(state consensus.StateReader, height *big.Int, config *params.ChainConfig) bool

IsDeveloperVerificationEnabled Since the state variables are as follow: 

bool public initialized;
bool public enabled;
address public admin;
address public pendingAdmin;
mapping(address => bool) private devs;

according to [Layout of State Variables in Storage](https://docs.soliditylang.org/en/v0.8.4/internals/layout_in_storage.html), and after optimizer enabled, the `initialized`, `enabled` and `admin` will be packed, and stores at slot 0, `pendingAdmin` stores at slot 1, and the position for `devs` is 2.
