Vitalik proposes gas cap to enhance Ethereum security, stability

Vitalik Buterin proposes EIP-7983 to cap transaction gas at 16.77 million, aiming to boost Ethereum security, stability, and zkVM compatibility.

Ethereum co-founder Vitalik Buterin and researcher Toni Wahrstätter have put forward EIP-7983, which aims to introduce a protocol-level cap on transaction gas usage to increase network security and performance.

The proposal sets a maximum gas limit of 16.77 million (2²⁴) for individual transactions. “By implementing this limit, Ethereum can enhance its resilience against certain DoS vectors, improve network stability, and provide more predictability to transaction processing costs,” the proposal reads.

Under the current Ethereum (ETH) architecture, a single transaction can theoretically consume the entire block’s gas limit, posing a risk of denial-of-service (DoS) attacks and leading to unpredictable network behavior.
