func (dht *IpfsDHT) handlePutValue(ctx context.Context, p peer.ID, pmes *pb.Message) (*pb.Message, error) {
	defer log.EventBegin(ctx, "handlePutValue", p).Done()
	dskey := key.Key(pmes.GetKey()).DsKey()

	if err := dht.verifyRecordLocally(pmes.GetRecord()); err != nil {
		log.Debugf("Bad dht record in PUT from: %s. %s", key.Key(pmes.GetRecord().GetAuthor()), err)
		return nil, err
	}

	data, err := proto.Marshal(pmes.GetRecord())
