function cancelGovernanceCall(
    bytes4 _selector
) external;

Cancel a timelocked governance call before it has been executed.

Only governance can call this method.

) external;

Execute the timelocked governance calls once the timelock period expires.

Only executor can call this method.

function getAddressUpdater(

    address _addressUpdater);

Returns the configured address updater.

function getCurrentRandom(
) external view returns (
    uint256);

Returns the random number for the previous epoch, obtained from the random numbers provided by all data providers along with their data submissions. Note that the random number for the previous epoch keeps updating as new submissions are revealed.

It never reverts.

function getFtsoManager(
) external view returns (
    contract IFtsoManagerGenesis);

Returns the address of the FtsoManager contract.

function getFtsoRegistry(
) external view returns (
    contract IFtsoRegistryGenesis);

    uint256[] _ftsoIndices,
    uint256[] _prices,
    uint256 _random
) external;

Reveals submitted prices during the epoch reveal period. The hash of FTSO indices, prices, random number, and voter address must be equal to the hash previously submitted with submitHash. Emits a PricesRevealed event.

function setAddressUpdater(
    address _addressUpdater
) external;

Sets the address updater contract. Only governance cal call this method.

function setTrustedAddresses(
    address[] _trustedAddresses
) external;

Set the trusted addresses that are always allowed to submit and reveal. Trusted addresses are used, for example, in fallback mode. Only FTSO Manager can call this method.

function submitHash(
    uint256 _epochId,
    bytes32 _hash
) external;

Submits a hash for the current epoch. Can only be called by FTSO data providers whitelisted through the VoterWhitelisted contract. Emits the HashSubmitted event.

function switchToProductionMode(
) external;

Enter the production mode after all the initial governance settings have been set. This enables timelocks and the governance can be obtained afterward by calling governanceSettings.getGovernanceAddress(). Emits GovernedProductionModeEntered.

function updateContractAddresses(

    address[] _contractAddresses
) external;

External method called from AddressUpdater only.

function voterWhitelistBitmap(
    address _voter
) external view returns (
    uint256);

Returns a bitmap of all FTSOs for which a data provider is allowed to submit prices or hashes.

function voterWhitelisted(

    uint256 _ftsoIndex
) external;

Called from the VoterWhitelister contract when a new voter has been whitelisted.

Only the VoterWhitelister contract can call this method.

function votersRemovedFromWhitelist(
    address[] _removedVoters,
    uint256 _ftsoIndex
) external;

Called from the VoterWhitelister contract when one or more voters have been removed.

Only the VoterWhitelister contract can call this method.

modifier onlyAddressUpdater()

modifier onlyFtsoManager()

Only the ftsoManager can call this method.

modifier onlyWhitelister()

Number of past random numbers remembered.

    contract IGovernanceSettings governanceSettings

Governance Settings.

    bool productionMode

When true, governance is enabled and cannot be disabled. See switchToProductionMode.

    mapping(bytes4 => struct GovernedBase.TimelockedCall) timelockedCalls
