Wu learned that Andrew Fitzgerald of Anza, a Solana ecosystem development company, drafted and submitted the SIMD-0290 proposal (Relax Fee Payer Constraint), suggesting to relax the treatment of invalid fee payers. The current rules result in the entire block being rejected due to invalid fee payers. The new proposal allows such transactions to be included in the block but not executed, in order to promote asynchronous verification/execution and reduce processing costs. The proposal balances efficiency improvements with security risks, ensuring backward compatibility, but further addressing community concerns about CUs computing and potential attacks is needed. https://www.
