The Ethereum community is currently embroiled in a crucial debate about potentially raising gas limits on the Ethereum mainnet by as much as 100%. The gas limit represents the maximum amount of gas that can be used for transactions within a single block on the Ethereum network, and discussions around this topic are heating up.
Perspectives on Raising Gas Limits
Supporters of increasing the gas limits, including various developers and influential community members, argue that doing so would significantly enhance the network’s capacity and spur innovation. Meanwhile, others, such as Toni Wahrstätter from the Ethereum Foundation, are more cautious. They warn that such an increase might compromise the network’s stability and security.
On December 9, Ethereum researcher Justin Drake took to social media to share his intent to set his validator to a new gas limit of 36 million, marking a 20% increase from the current cap of 30 million. This decision comes amidst enthusiastic calls from fellow developers to push for even higher limits — with some speculating that they could reach up to 60 million.
The Debate on Layer One vs. Layer Two
Emmanuel Awosika, the creative director at 2077 Collective, articulated the rationale behind raising gas limits. According to him, this move would signal Ethereum’s dedication to innovation and broaden the opportunities available to developers. He highlighted how the existing gas limits can hinder the deployment of certain applications, as surges in popularity lead to soaring gas prices that degrade user experiences. By expanding the gas capacity, more developers would feel empowered to launch projects directly on layer one (L1) without the fear of being priced out.
At the heart of this debate is the pivotal question: Should L1 evolve to accommodate high-value decentralized finance (DeFi) initiatives, or should those activities be primarily channeled to Ethereum’s layer twos (L2s) to mitigate the L1’s scaling limitations while retaining its decentralization and integrity?
Though the Ethereum developer community has largely leaned towards an L2-centric strategy—an approach championed by co-founder Vitalik Buterin since 2022—Awosika posits that the focus may have tipped too far. He acknowledged the prevailing agreement on the merits of the L2 roadmap but emphasized the necessity of keeping high-value applications on L1, thus preserving Ethereum’s distinctive advantage over Bitcoin, which emphasizes structural permanence.
Technical Concerns with Increased Gas Limits
Skepticism about an aggressive hike in gas limits is echoed by crypto commentator Evan Van Ness. He contends that such an increase might not address the underlying scalability issues inherent to L1. Even if gas limits are raised dramatically, he fears that the ensuing spike in demand would simply trigger a return to exorbitant transaction costs, thus nullifying any benefits from the increase.
Adding to the technical concerns, Wahrstätter pointed out that Ethereum’s consensus layer client currently caps the uncompressed block size at 10 mebibytes (MiB) to enable effective network propagation. With a proposed gas limit of 60 million, this cap would be exceeded, potentially causing propagation difficulties, missed validator opportunities, and an overall destabilization of the network. He clarified that validators determine the gas limit through their votes with each block, in stark contrast to the established procedures governing Ethereum Improvement Proposals (EIPs). Notably, the gas limit has remained unchanged since the Merge, where miners historically adhered to practices established by core developers before making adjustments.
Despite these technical challenges surrounding any increases beyond 40 million, there seems to be growing agreement among developers that establishing a new baseline of 36 million could be a practical first step. Observers expect significant interest from developer groups in the approaching weeks.
Tensions around gas limits and innovation on L1 have escalated following an announcement by Ethereum core developer Max Resnick. He declared his switch to Solana, citing a stagnant developer environment and an insufficient commitment to L1 scalability as driving forces behind his decision. Resnick had previously criticized the trend towards prioritizing Layer 2 solutions at the expense of enhancing L1 scalability, advocating for a more balanced strategy for the sustainability and expansion of mainnet applications.
Awosika commented on Resnick’s departure and the community’s reactions, viewing them as a reflection of larger underlying issues within Ethereum. He expressed disappointment that an innovative figure like Resnick felt compelled to leave and received a largely dismissive response from many in the community.
