Functions

func AggregatePublicKeys 

func AggregatePublicKeys(vdrs []*CanonicalValidator) (*bls.PublicKey, error)

AggregatePublicKeys returns the public key of the provided validators.

Invariant: All of the public keys in [vdrs] are valid.

func NewManager 

func NewManager() *manager

NewManager creates a new validator manager

func SumWeight 

func SumWeight(vdrs []*CanonicalValidator) (uint64, error)

SumWeight returns the total weight of the provided validators.

Types

type CanonicalValidator 

type CanonicalValidator struct {
	PublicKey      *bls.PublicKey
	PublicKeyBytes []byte // Uncompressed bytes for canonical ordering
	Weight         uint64
	NodeIDs        []ids.NodeID // Can have multiple NodeIDs with same public key
}

CanonicalValidator represents a single validator with BLS public key in canonical form

func FilterValidators 

func FilterValidators(
	indices set.Bits,
	vdrs []*CanonicalValidator,
) ([]*CanonicalValidator, error)

FilterValidators returns the validators in [vdrs] whose bit is set to 1 in [indices].

Returns an error if [indices] references an unknown validator.

func (*CanonicalValidator) Compare 

func (v *CanonicalValidator) Compare(o *CanonicalValidator) int

Compare implements utils.Sortable for canonical ordering

type CanonicalValidatorSet 

type CanonicalValidatorSet struct {
	// Validators slice in canonical ordering of the validators that has public key
	Validators []*CanonicalValidator
	// The total weight of all the validators, including the ones that doesn't have a public key
	TotalWeight uint64
}

CanonicalValidatorSet represents a validator set in canonical ordering

func FlattenValidatorSet 

func FlattenValidatorSet(vdrSet map[ids.NodeID]*GetValidatorOutput) (CanonicalValidatorSet, error)

FlattenValidatorSet converts the provided [vdrSet] into a canonical utils. Also returns the total weight of the validator set.

	TotalWeight(netID ids.ID) (uint64, error) // Deprecated: use TotalLight

	// Mutable operations
	AddStaker(netID ids.ID, nodeID ids.NodeID, publicKey []byte, txID ids.ID, light uint64) error
	AddWeight(netID ids.ID, nodeID ids.NodeID, light uint64) error

	NumNets() int

	// Additional utility methods
	Count(netID ids.ID) int
	NumValidators(netID ids.ID) int // Alias for Count
	Sample(netID ids.ID, size int) ([]ids.NodeID, error)
	GetValidatorIDs(netID ids.ID) []ids.NodeID
	SubsetWeight(netID ids.ID, nodeIDs set.Set[ids.NodeID]) (uint64, error)
	GetMap(netID ids.ID) map[ids.NodeID]*GetValidatorOutput
	RegisterCallbackListener(listener ManagerCallbackListener)
	RegisterSetCallbackListener(netID ids.ID, listener SetCallbackListener)
}

Manager manages validator sets

type ManagerCallbackListener interface {
	OnValidatorAdded(netID ids.ID, nodeID ids.NodeID, light uint64)
	OnValidatorRemoved(netID ids.ID, nodeID ids.NodeID, light uint64)
	OnValidatorLightChanged(netID ids.ID, nodeID ids.NodeID, oldLight, newLight uint64)
}

ManagerCallbackListener listens to manager changes

type Set 

type Set interface {
	Has(ids.NodeID) bool
	Len() int
	List() []Validator
	Light() uint64
	Sample(size int) ([]ids.NodeID, error)
}

Set represents a set of validators

	OnValidatorRemoved(nodeID ids.NodeID, light uint64)
	OnValidatorLightChanged(nodeID ids.NodeID, oldLight, newLight uint64)
}

SetCallbackListener listens to validator set changes

type Sortable 

type Sortable[T any] interface {
	Compare(T) int
}

Sortable is a type that can be compared to another element of the same type.

type State 

type State interface {
	// GetValidatorSet returns validators at a specific height for a network
	GetValidatorSet(ctx context.Context, height uint64, netID ids.ID) (map[ids.NodeID]*GetValidatorOutput, error)
