Usage

From source file:co.rsk.blockchain.utils.BlockGenerator.java

    byte[] parentMGP = (parent.getMinimumGasPrice() != null) ? parent.getMinimumGasPrice()
            : BigInteger.valueOf(10L).toByteArray();
    BigInteger minimumGasPrice = new MinimumGasPriceCalculator().calculate(new BigInteger(1, parentMGP),
            BigInteger.valueOf(100L));

    return new Block(parent.getHash(), // parent hash
