I have a private parity node setup on my laptop. How can I make sure that there is 0 transaction fee whenever a transaction is posted in this private ethereum blockchain, meaning that I can post a transaction giving "gas: 0"?
Example: Account A has 20 ethers, Account B has 0 ether. When I transfer 10 ether from Account A to Account B, Account A now shows 9.980 and Account B shows 10.
How can I prevent the extra gas being deducted?
