Remove ether from PoA private network

Question

I try to setup a private network containing three nodes (bootnode, sealer, transaction node with rpc) and PoA. So far so good. The thing is I don't want to have any ether nor do I want to pay any gas for transactions since I only use the network to create contracts and interact with them (used it as a fancy database), so I don't need an actual currency. I used geth to setup the three nodes and as long as I have ether in my system (accounts are funded and I pay the gasprice) all works fine. But as soon as I try to set the accepted gasprice for the sealer node via the --miner.gasprice=0 and don't fund my accounts the transactions are not put to the blockchain anymore. I'd be very happy if there is a solution to this. Cheers

Answer 1

You are still going to need gas as the internal unit of accounting, because otherwise a transaction can contain an infinite for loop that never terminates, crashing your nodes.
