    Transaction transaction = new Transaction();
    Random r = new Random();
    int[] hash = new int[Curl.HASH_LENGTH], trits = Arrays.stream(new int[TransactionViewModel.TRINARY_SIZE]).map(i -> r.nextInt(3) - 1).toArray();
    Sponge curl = SpongeFactory.create(SpongeFactory.Mode.CURLP81);
    curl.absorb(trits, 0, trits.length);
    curl.squeeze(hash, 0, Curl.HASH_LENGTH);
    transaction.bytes = Converter.allocateBytesForTrits(trits.length);
    Converter.bytes(trits, transaction.bytes);
// assertTrue("Should be a new, unique transaction", !Tangle.instance().save(transaction).get());
