The co-founder Ethereum Vitalik Buterin and researcher Toni Wahrstätter presented EIP-7983, which aims to introduce a ceiling in the protocol on the use of transaction gases to increase the safety and performance of the network.
The proposal fixes a maximum gas limit of 16.77 million (2²⁴) for individual transactions. “By implementing this limit, Ethereum can improve its resilience against certain back vectors, improve network stability and provide greater predictability to transaction processing costs,” said the proposal.
As part of the current Ethereum (ETH) architecture (ETH), a single transaction can theoretically consume the gas limit of the entire block, posing a risk of service denial attacks (back) and leading to unpredictable network behavior.
By capping individual transactions, EIP-7983 seeks to distribute gas consumption more uniformly, which reduces the chances of unique transactions overwhelming with block capacity.

Gas cap to increase ZKVM compatibility
The proposed ceiling is also designed to improve compatibility with virtual machines (ZKVMS) with zero knowledge by encouraging important transactions to divide into smaller pieces.
According to the project, transactions specifying gas limits beyond 16.77 million would be rejected during block validation, ensuring that they cannot enter the network or be included in new blocks. The ceiling is independent of the overall limit of block gas, which minors and validators can always adjust in the existing consensus rules.
Buterin and Wahrstätter chose 16.77 million as a ceiling to balance complexity and performance, arguing that it adapts to current advanced use cases and contract deployments without introducing unnecessary risks.
“This value allows the most recent use cases, including deployments of contracts and advanced challenge interactions while guaranteeing coherent performance characteristics,” says the proposal.
Although the proposal is not compatible behind for transactions exceeding the new limit, the authors have noted that most existing transactions fall well below the ceiling, minimizing the impact on users and developers.
EIP-7983 is based on previous efforts, such as EIP-7825, to improve the predictability of the execution of transactions.

Vitalik wants to make Ethereum simple
In May, Buterin called to simplify the basic protocol of the Ethereum network to stimulate efficiency, safety and accessibility, inspired by the minimalist approach to Bitcoin.
At the time, he proposed to restructure Ethereum’s architecture through consensus, execution and shared components to reach a leaner design within five years. Buterin argued that the growing complexity of Ethereum has led to longer development times, higher costs and increased security risks.
More recently, the brain Ethereum has introduced a new type of digital identity system nicknamed “pluralist identity”, arguing that it could protect confidentiality while allowing equitable participation in digital life.
