IsInsufficientSignaturesError returns whether err is an InsufficientSignaturesError

func IsInvalidSignatureIncludedError

func IsInvalidSignatureIncludedError(err error) bool

IsInvalidSignatureIncludedError returns whether err is an InvalidSignatureIncludedError

func IsInvalidSignerIdxError

func IsInvalidSignerIdxError(err error) bool

IsInvalidSignerIdxError returns whether err is an InvalidSignerIdxError

func NewDuplicatedSignerIdxErrorf

func NewDuplicatedSignerIdxErrorf(msg string, args ...interface{}) error

RandomBeaconThreshold returns the threshold (t) to allow the largest number of malicious nodes (m) assuming the protocol requires:

m<=t for unforgeability
n-m>=t+1 for robustness

Types
