Vitalik: Ethereum plans to set a single transaction limit of 16,777,216 gas in 2025

ChainCatcher News, Vitalik Buterin stated that Ethereum will continue to enhance security and scalability through "hard invariants."

He reviewed the 2021 EIP-2929/3529, which increased SLOAD costs and weakened refunds; the 2024 Dencun upgrade, which weakened SELFDESTRUCT; and the 2025 plan to set a single transaction limit of 16,777,216 gas, restricting the executable size of a single transaction or block, reducing DoS risks, and simplifying clients. He also suggested that in the future, limits should be set for code byte access, ZK‑EVM prover cycles, and memory pricing.
