Hi,
I came from Japan,Please forgive me for my bad English...
I have a private Ethereum blockchain,I don't want transaction fee whenever a transaction is posted in this private ethereum blockchain and I also want there is no benefit for miner,Because this conflicts with the company's business logic.
But I couldn't find any solution in stackoverflow and other forums which I know.Is it only possible to solve the problem by modify go-ethereum source?
Any help is appreciated.

如题，公司内部用的代币，做一些子公司之间的抵顶和人员的奖惩，如果出现了挖矿还有收益，那帐就不好拉平。
另外交易的手续费能设置为零么？

谢谢大家，刚开始做区块链相关的开发，请多多指教，谢谢！
