	*tss.BaseParty
	// contains filtered or unexported fields
}

func (*LocalParty) FirstRound

func NewLocalPartySaveData

func NewLocalPartySaveData(partyCount int) (saveData LocalPartySaveData)

func (LocalPartySaveData) OriginalIndex

func (save LocalPartySaveData) OriginalIndex() (int, error)

recovers a party's original index in the set of parties during keygen

type LocalSecrets

type LocalSecrets struct {
	K       *big.Int
	R       *big.Int
	ShareID *big.Int
}
