According to a report by Trustnodes on August 19th, V God proposed to change the highest-cost auction mode used in the current transaction to the fixed-charge mode. The idea is to replace the current fluctuating cost calculation with a protocol rule that sets the cost at a certain level, combined with a formula that allows for a change based on capacity. Under this design, all charges can be included in a pool of funds, which are distributed to the miners on average as block rewards. V God said that the proposal is related to most public chains and is being considered in Ethereum. This is basically the commonality of transaction processing, so that miners do not compete with each other for the transactions they deal with, they share the cost rather than paying directly through the transaction fee.
