Ethereum Eyes Gas Cap to Stop DoS Attacks

Ethereum Eyes Gas Cap to Stop DoS Attacks

The Ethereum network has received a proposal, EIP-7983, to improve its defense against Déni de Service (DOS) attacks and improve the overall stability of the platform.

The proposed update, drawn by researcher Ethereum Toni Wahrstätter and the co-founder Vitalik Buterin, seeks to establish a limit of use of gas. This measure aims to prevent disturbances caused by heavy resource transactions.

The new Ethereum proposal reveals how a transaction could disrupt the chain

The key aspect of the proposal is the introduction of a ceiling on the use of gas by transaction, with a maximum threshold fixed at 16.77 million gas units (2 ^ 24).

The developers argued that this gas limit is a balanced solution. It allows advanced transactions, such as the deployment of contracts and the facilitation of sophisticated DEFI interactions. At the same time, it ensures predictability and equity in execution.

“As part of the validation of the block before treatment, any block having a transaction with Gaslimit> 16.77 million is considered invalid and rejected,” said the PDE.

Above all, this limit would apply to all transactions, regardless of the block gas limit determined by minors or validators. Transactions trying to go beyond this threshold would be rejected, triggering an error code.

However, EIP-7983 also suggests a mechanism to divide larger transactions into smaller and more manageable units. This approach considerably reduces the risk of a single transaction crushing the network.

According to the developers, the motivation behind the proposal stems from current models in which unique transactions can consume almost the entire block gas limit.

Such scenarios present significant risks, in particular the potential for back attacks and reduced compatibility with zero knowledge virtual machines (ZKVMS). They also contribute to an unequal load distribution during execution.

Researchers emphasize that high -intensity transactions introduce unpredictable performance results and can subject execution threads, resulting in broader instability in the network.

Researchers think that Ethereum can achieve better distribution of resources by dividing large transactions into smaller units and imposing a ceiling on the individual use of transaction gas. This approach would also lead to a more stable and scalable network.

“This adjustment should have a minimum impact of users and DAPPs, because most transactions fall well below the proposed ceiling,” they said.

The update is currently being examined, the developers considering its implementation and its potential technical compromises. If it is adopted, EIP-7983 could considerably improve the resilience and scalability of Ethereum as it continues to grow.
