IVoterRegistry

Manages the registration of voters for upcoming reward epochs.

Sourced from IVoterRegistry.sol on GitHub.

Functions​

chilledUntilRewardEpochId​

In case of providing bad votes (e.g. ftso collusion), the beneficiary can be chilled for a few reward epochs. If beneficiary is chilled, the vote power assigned to it is zero.

function chilledUntilRewardEpochId(
    bytes20 _beneficiary
) external view returns (
    uint256 _rewardEpochId
);

Parameters​

  • _beneficiary: The beneficiary (c-chain address or node id).

Returns​

  • _rewardEpochId: The reward epoch id until which the voter is chilled.

getNumberOfRegisteredVoters​

Returns the number of registered voters for a given reward epoch. Size can be zero if the reward epoch is not supported (before initial reward epoch or future reward epoch). Size for the next reward epoch can still change until the signing policy snapshot is created.

function getNumberOfRegisteredVoters(
    uint256 _rewardEpochId
) external view returns (
    uint256
);

Parameters​

  • _rewardEpochId: The reward epoch id.

getRegisteredVoters​

Returns the list of registered voters for a given reward epoch. List can be empty if the reward epoch is not supported (before initial reward epoch or future reward epoch). List for the next reward epoch can still change until the signing policy snapshot is created.

function getRegisteredVoters(
    uint256 _rewardEpochId
) external view returns (
    address[]
);

Parameters​

  • _rewardEpochId: The reward epoch id.

isVoterRegistered​

Returns true if a voter was (is currently) registered in a given reward epoch.

function isVoterRegistered(
    address _voter,
    uint256 _rewardEpochId
) external view returns (
    bool
);

Parameters​

  • _voter: The voter address.
  • _rewardEpochId: The reward epoch id.

maxVoters​

Maximum number of voters in one reward epoch.

function maxVoters(
) external view returns (
    uint256
);

newSigningPolicyInitializationStartBlockNumber​

Returns the block number of the start of the new signing policy initialisation for a given reward epoch. It is a snaphost block of the voters' addresses (it is zero if the reward epoch is not supported).

function newSigningPolicyInitializationStartBlockNumber(
    uint256 _rewardEpochId
) external view returns (
    uint256
);

Parameters​

  • _rewardEpochId: The reward epoch id.

publicKeyRequired​

Indicates if the voter must have the public key set when registering.

function publicKeyRequired(
) external view returns (
    bool
);

registerVoter​

Registers a voter if the weight is high enough.

function registerVoter(
    address _voter,
    struct IVoterRegistry.Signature _signature
) external;

Parameters​

  • _voter: The voter address.
  • _signature: The signature.

Events​

BeneficiaryChilled​

Event emitted when a beneficiary (c-chain address or node id) is chilled.

event BeneficiaryChilled(
    bytes20 beneficiary,
    uint256 untilRewardEpochId
)

VoterRegistered​

Event emitted when a voter is registered.

event VoterRegistered(
    address voter,
    uint24 rewardEpochId,
    address signingPolicyAddress,
    address submitAddress,
    address submitSignaturesAddress,
    bytes32 publicKeyPart1,
    bytes32 publicKeyPart2,
    uint256 registrationWeight
)

VoterRemoved​

Event emitted when a voter is removed.

event VoterRemoved(
    address voter,
    uint256 rewardEpochId
)

Structures​

Signature​

struct Signature {
  uint8 v;
  bytes32 r;
  bytes32 s;
}
