Functions

func CheckPartitionSystemIdentifiersUnique 

func CheckPartitionSystemIdentifiersUnique[T SystemDescriptionRecordGetter](records []T) error

func GetMinQuorumThreshold 

func GetMinQuorumThreshold(totalRootValidators uint32) uint32

GetMinQuorumThreshold calculates minimal quorum threshold from total number of validators

func NewValidatorTrustBase 

func NewValidatorTrustBase(publicKeyInfo []*PublicKeyInfo) (map[string]abcrypto.Verifier, error)
