[Vitalik: Ethereum plans to set the single transaction limit to 16,777,216 gas in 2025] Vitalik Buterin stated that Ethereum will enhance security and scalability through 'hard invariants.' He reviewed the 2021 EIP-2929/3529 updates, which increased SLOAD costs and weakened the refund mechanism, as well as the 2024 Dencun update that reduces the impact of SELFDESTRUCT. He revealed plans for 2025 to set the single transaction limit to 16,777,216 gas to restrict the executable scale of single transactions or single blocks, reduce the risk of DoS attacks, and simplify client operations. Additionally, he suggested setting future limits for code byte access, ZK-EVM prover cycles, and memory pricing.

[Vitalik Proposes New Hard Rules to Enhance Ethereum Protocol Security and Efficiency] Vitalik Buterin posted on platform X, stating that modifying several fixed hard rules of the Ethereum protocol could not only improve its security but also enhance its adaptability for the future. The specific improvements he mentioned include: EIP-2929 and EIP-3529 implemented in 2021 (increasing gas fees for storage read operations and reducing gas refund amounts), the weakening of the self-destruct contract instruction functionality accompanying the Dencun upgrade in 2024, and setting a single transaction gas fee cap at 16,777,216 in 2025. These modifications establish hard limits for individual blocks or transactions, mitigating the risk of denial-of-service attacks, simplifying client code, and expanding pathways to improve system efficiency. Vitalik also plans to advance the implementation of rules such as limiting code byte size, restricting computation cycles for zero-knowledge proof verifiers, and adjusting memory gas accounting methods.
