On May 13th, according to the Solana developer forum, the proposal to enable full priority fee rewards for validators on Solana Mainnet-beta suggests adjusting the priority fee structure to give 100% of the reward to validators. The proposer of the discussion stated that the implementation of this proposal requires the use of a feature gate. While the payment structure for transaction submitters will not change, software that includes this proposal will distribute a larger proportion of fees to validators than previous versions. Therefore, ensuring a smooth transition for all validators to the new feature gate at the time boundary is crucial for maintaining consistency.
