Wu learned that the Solara validator client Agave 4.4 is expected to activate several protocol updates during its release cycle: allowing blocks to include transactions that failed to validate fee payment accounts, validators will skip the execution of such transactions instead of invalidating the entire block, reducing reliance on future asynchronous execution; automatically adjusting storage account capacity based on the new code size during program upgrades and returning excess SOL released during scaling down to designated accounts; unifying the forward error correction (FEC) group used for block propagation to 32 data shards and 32 coded shards, simplifying block validation; and excluding inactive staking within the corresponding reward cycle in staking reward calculation, reducing consensus processing complexity. Furthermore, the Agave 4.4 release cycle is expected to complete the final three phases of the account storage rent reduction plan, reducing the minimum balance per byte required to maintain rent-free status from the initial 6,960 lamports to 696 lamports, a cumulative reduction of 90%. According to Ghost's estimates, after the full implementation of the relevant adjustments, approximately 3.08 million SOL tokens (worth about $300 million) on the chain will be recoverable. https://wublock123.com/news/solana-agave-4-4-protocol-updates-account-rent-cut-90-70888
