Ethereum co -founder Vitalik buterin and Toni Wahrstätter, researcher Ethereumhave submitted and proposal This will limit the maximum gas that can use one transaction. Design, EIP 7983, claims:
“By implementing this limit, the Ethereum can increase its resistance to a certain DOS. [Denial of Service attack] Vectors, improve network stability and provide greater predictability of transaction processing costs. ”
The latest design is a modified version EIP 7825who was introduced in November last year, but has stagnated since then.
The proposal will limit the use of gas for individual transactions to 16.77 million gas
The aim of the proposal is to promote a maximum limit of 16.77 million gas for any individual transaction, nearly half of the 30 million gas limit designed in the EIP 7825. This limit, according to burthrin and wahrstätter, will be applicable regardless of the gas block set miners or validators.
The implementation of this proposal will see that transactions determine the gas limit over 16.77 million gas that will be invalidated. This means that during the validation of the transaction, transactions exceeding the gas limit will be rejected and excluded from the transactions fund. Similarly, during the block verification, any block contains a transaction that exceeds the gas limit, invalid.
Bterin and Wahrstätter’s chosen gas limit of 16.77 million gas will provide a “balance between allowing complex transactions while maintaining predictable boundaries” as proposed. The authors added:
“This value allows most of the current applications, including the deployment of contracts and advanced Defi interactions, while ensuring consistent performance characteristics.”
During implementation, the proposal will require users and decentralized applications (DAPP) to distribute transactions with higher gas limits into smaller operations. However, buterin and Wahrstätter expect the limit to affect the minimum number of users and DAPP, as most of the current transactions will fall significantly below the proposed limit.
Why is the gas limit setting the transaction
The current Ethereum architecture allows transactions to theoretically consume the entire gas limit of the block. This architecture carries several risks.
For example, allowing a single transaction to consume a majority or all gas block limit can facilitate DOS attacks. During DOS attacks, bad actors try to overwhelm the nets by converting spam transactions. This causes the network not to provide the service to real users.
According to the design, the absence of a transaction gas limit can also lead to an uneven distribution of load and affect the network stability.
Having variable use of gas can also cause imbalance in the distribution of loads across transactions in the block. In addition, high gas transactions also cause longer blocks of blocks, which can affect user experience.
Advantages of setting the transaction gas limit
According to Buterin and Wahrstätter, limiting the use of gas use of individual transactions can help reduce the risk of attacks on one DOS transaction. In essence, the limit sets a railing that prevents harmful actors from using the network width through large spam transactions.
The limit would also ensure that the gas would be allocated fairly across transactions in the block, the proposal said. The cap is expected to verify the blocks of “more predictable and uniform”.
However, the most important advantage would be increased compatibility with virtual machines for zero knowledge (ZKVMS). Encouraging transactions with heavy gas limits to be divided into smaller pieces “allowing better participation in distributed demonstration systems” and allows “a more predictable design of the ZKVM circuit”, the proposal said.
