Austin Federa, the strategic director of the Solana Foundation, posted on the X platform that he saw some confusion about SWQoS (Stake Weighted QoS). He explained that there are (will be) 3 ways to increase the possibility of transaction inclusion on Solana:
1. Priority Fees: Used when calculation/inclusion is a bottleneck. Similar to increasing gas fees on other networks, it is global;
2. Local Fee Markets: Used when state contention (multiple people trying to do the same thing) becomes a bottleneck, it is local;
3. Stake Weighted QoS: Sybil/spam identification engine, which can be used with PF/LFM or alone, it is global.
It will not be either this or that on Solana. These features will provide optionality for operators: depending on their settings, priorities, and configurations, there are multiple ways to achieve similar goals, in addition to other non-protocol solutions such as MEV relayers.
There will undoubtedly be some externalities in the V0.5 version deployed now that will have to be addressed over time through additional protocol governance, but we believe it is best to deliver something and adjust when everyone can see the same real data.
