Functions ¶

func BallotIndex ¶

func BallotIndex(voterIndex uint64) (uint64, error)

BallotIndex returns a BallotIndex on the lower half of the 64 bit space, between BallotMin and BallotMax.

BallotIndex = BallotMin + voterIndex

func BallotInputsHashRTE ¶

func BallotInputsHashRTE(
	processID *big.Int,
	ballotMode BallotMode,
	encryptionKeyX *big.Int,
	encryptionKeyY *big.Int,
	address *big.Int,
	voteID uint64,
	ballot []*big.Int,
	weight *big.Int,
) (*big.Int, error)

BallotInputsHashRTE computes the ballot inputs hash using RTE-encoded points.

func StateRoot ¶

func StateRoot(processID, censusOrigin, pubKeyX, pubKeyY, ballotMode *big.Int) (*big.Int, error)

StateRoot computes the state root hash for the process parameters.

func VoteID ¶

func VoteID(processID, address, k *big.Int) (uint64, error)

VoteID calculates the poseidon hash of: the process ID, voter's address and a secret value k. This is truncated to the least significant 63 bits, and then shifted to the upper half of the 64 bit space by setting the first bit to 1.

Types ¶

type BallotMode ¶

type BallotMode struct {
	NumFields      uint8  `json:"numFields" cbor:"0,keyasint,omitempty"`
	GroupSize      uint8  `json:"groupSize" cbor:"1,keyasint,omitempty"`
	UniqueValues   bool   `json:"uniqueValues" cbor:"2,keyasint,omitempty"`
	CostFromWeight bool   `json:"costFromWeight" cbor:"3,keyasint,omitempty"`
	CostExponent   uint8  `json:"costExponent" cbor:"4,keyasint,omitempty"`
	MaxValue       uint64 `json:"maxValue" cbor:"5,keyasint,omitempty"`
	MinValue       uint64 `json:"minValue" cbor:"6,keyasint,omitempty"`
	MaxValueSum    uint64 `json:"maxValueSum" cbor:"7,keyasint,omitempty"`
	MinValueSum    uint64 `json:"minValueSum" cbor:"8,keyasint,omitempty"`
}

BallotMode defines the ballot configuration fields used by the spec.

func (BallotMode) Pack ¶

func (bm BallotMode) Pack() (*big.Int, error)

Pack packs the ballot mode fields into a single field element.

func (BallotMode) String ¶

func (bm BallotMode) String() string

String returns a string representation of the ballot mode.

func (BallotMode) Validate ¶

func (bm BallotMode) Validate() error

Validate validates the ballot mode fields for basic consistency.
