type TimestampRegistry interface {
	Get(pubkey string) (timestamp uint64, ok bool)
}

type VerifyReq 

type VerifyReq struct {
	Signature [96]byte
	Pubkey    [48]byte
	Msg       [32]byte
	// Unique identifier of payload
	// if needed to be passed back in response
	ID       int
	Response *StoreResp
}

VerifyReq is a request structure used in communication between api calls and fixed set of worker goroutines it's using return channel pattern, meaning that after sent the sender locks on that channel to get the response
