Q) Will minters stop processing transactions and cause a degradation of service on transaction processing.
- Transaction processing is cheap at reasonable volume. There is very little incentive to do this.
- I don't view block chain system as the most suitable medium for high volume transaction processing, so transaction fees in PPC serve an important mechanism to control volume on the block chain. This is why transaction fees are currently fixed at 0.01 per KB.
- There were proposals that distribute partial transaction fees to minters but I am not in favor of them at the moment.
- If this truly becomes a problem, the default minting algorithm could possibly be revised to include an adversarial strategy to deter such behavior, for example delaying building on top of a 'cheating' block.
- Demanding fees from users wouldn't be very different from bitcoin, as it's construed as a legitimate action from minters. Only difference is in PPC you would need to ask users to add additional outputs in order to collect the fees yourself, causing bloating. I doubt such strategy would work well for minters though, again PPC is meant to be highly decentralized and not sacrificing decentralization for high volume transaction processing.
