Lines 109 to 118 in eb63d30

	internal bool LoadPolicy(StoreView snapshot)
	{
	_maxTxPerBlock = (int)NativeContract.Policy.GetMaxTransactionsPerBlock(snapshot);
	long newFeePerByte = NativeContract.Policy.GetFeePerByte(snapshot);
	uint newExecFeeFactor = NativeContract.Policy.GetExecFeeFactor(snapshot);
	bool policyChanged = newFeePerByte > _feePerByte || newExecFeeFactor > _execFeeFactor;
	_feePerByte = newFeePerByte;
	_execFeeFactor = newExecFeeFactor;
	return policyChanged;
	}

I think there is no need to return policyChanged now.

And also we don't need to send the transactions from MemoryPool to Blockchain.

And also we don't need to send the transactions from MemoryPool to Blockchain.

If there are more transactions in mempool than MaxTransactionPerBlock I think this logic will be executed?

Let's remove policyChanged first.

@erikzhang Please have a look
