ChainCatcher news, Austin Federa, the strategic head of the Solana Foundation, stated that Solana will improve transaction prioritization through the introduction of three new mechanisms to alleviate network congestion. These three mechanisms are:Priority Fees: Used to calculate resources/transaction packaging when it becomes a bottleneck, essentially similar to the practice of increasing Gas fees in other blockchain networks, with global properties.Local Fee Markets: Used for bottlenecks that arise when multiple parties compete for the same state resources, with local properties.Stake Weighted QoS: A mechanism for identifying witch attacks and spam transactions, which can be used in conjunction with the first two mechanisms or independently, with global properties.Federa emphasized that on Solana, these three functions are not mutually exclusive but provide flexible options for validator nodes. Validators can utilize different combinations based on their configurations, priorities, and specific situations to achieve similar goals.Additionally, there are some other non-protocol layer solutions, such as MEV relayers. The currently deployed V0.5 version will undoubtedly bring some externality issues that need to be addressed over time through protocol governance.However, Federa believes that, in comparison, launching new features as soon as possible and then making adjustments based on real data is a better choice. Federa also specifically clarified that this update does not change the costs of running a validator node, the required staking (still 1 SOL), the participation threshold for validation (still permissionless), or the base fees and rewards that validators can earn.
