type ExternalSender

type ExternalSender interface {
	// Send a GetAcceptedFrontier message for chain [chainID] to validators in [validatorIDs].
	// The validator should reply by [deadline].
	// Returns the IDs of validators that may receive the message.
	// If we're not connected to a validator in [validatorIDs], for example,
	// it will not be included in the return value.
