Vitalik: Ethereum's 2025 plan sets the single transaction limit at 16,777,216 gas

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 which weakens SELFDESTRUCT, and the 2025 plan to set a single transaction gas limit of 16,777,216, restricting the executable size of a single transaction or block, reducing DoS risks and simplifying the client. He also suggested setting limits for code byte access, ZK-EVM prover cycles, and memory pricing in the future.
