A new proposal in the Ethereum 
$3,094 ecosystem, known as EIP-7983, aims to bring significant changes. Developed by Ethereum’s founder Vitalik Buterin and researcher Toni Wahrstätter, this draft seeks to limit the maximum amount of gas that can be used in a single transaction to 16.77 million. This regulation is intended to ensure the efficient use of blocks and encourage the division of transactions into smaller parts.
Single Transaction Gas Limit and Its Reasons
According to the proposal, transactions will be prevented from using more than 16.77 million gas. One of the objectives is to prevent large transactions from consuming all block capacity and causing congestion for other users’ transactions. This limit is also expected to make it necessary for large transactions to be divided into smaller parts for execution.
In recent years, there has been a focus on solutions to increase scalability and transaction speed on Ethereum. In this context, the new proposal aims to prevent bottlenecks on the chain and ensure a more balanced use of resources. Along with network stability, an increase in the predictability of transaction fees and block times is expected.
Zero-Knowledge Layers and Parallel Transaction Flow
Authorities express that this change could particularly facilitate the development of zero-knowledge proof-based layers. Smaller and fixed transaction sizes are thought to make it easier to distribute transactions across multiple threads, thus enhancing Ethereum’s scalability. Transitioning to a parallel transaction infrastructure is seen as a crucial step in overcoming current bottlenecks.
Toni Wahrstätter, Ethereum Researcher: “Breaking up large transactions makes participation in distributed verification systems easier. While zkVMs can theoretically parallelize within a transaction, this is usually not preferred in practice due to increased complexity. Therefore, downsizing transactions seems more reasonable.”
The planned limit under EIP-7983 may directly affect large contracts in the DeFi ecosystem and developers executing massive deployments. For small-scale users and ordinary transactions, this regulation is expected to operate indirectly and quietly, making fees and block occupancy more predictable.
Justifications and Comparisons with Previous Proposals
A similar idea in the past, EIP-7825, proposed a 30 million gas limit; but with EIP-7983, this limit is nearly halved. The new limit is preferred to balance network security and block verification times, indicating a stricter control.
Vitalik Buterin: “I strive to simplify Ethereum’s core. My priority is to reduce complexity and potential vulnerabilities without completely eliminating advanced use cases.”
Buterin’s proposed approach is expected to reduce complexity on the platform while preserving advanced usage capabilities. It is also underlined that it can enhance overall security by preventing network congestion.
For developers, this change may not have a significant impact beyond heavy DeFi contracts and large projects. However, the necessity of breaking down particularly large transactions may require developing new working models. End-users are expected to experience this update mostly in the background and unnoticed.
In the upcoming period, by tightening the gas limit per transaction, Ethereum might be aiming to establish a more secure and predictable ecosystem. This change can also be seen as an important step in preparing the ecosystem for future parallel transaction capabilities. Users could encounter a more stable and predictable fee structure, while developers may need to design more modular and efficient applications.
