Vitalik Buterin Calls For Community Discussion On Ethereum Decentralization Goals And Gas Limit Strategy
In Brief
Vitalik Buterin initiated a conversation on the Ethereum Magicians forum, emphasizing the importance of defining Ethereum’s decentralization goals—specifically, which user guarantees the network aims to preserve and which compromises it is unwilling to make.
Ethereum co-founder Vitalik Buterin initiated a conversation on the Ethereum Magicians forum titled “Formalizing decentralization goals in the context of larger L1 gas limits and 2020s-era tech.” In the post, he emphasized the importance of explicitly defining Ethereum’s decentralization goals—specifically, identifying which user guarantees the network aims to preserve and which compromises it is not willing to make.
Vitalik Buterin outlined a framework categorizing nodes into three types based on their roles and trust assumptions: Light nodes, which are capable of verifying chain correctness and availability, and accessing necessary data privately—assuming at least one honest heavy node exists to maintain liveness, while safety remains unconditional; Medium nodes, which Ethereum relies on with an n/2-of-n trust model, such as attesters in staking and FOCIL participants; and Heavy nodes, which the protocol trusts on a 1-of-n basis for functions like optimal block construction or proof generation.
Importantly, FOCIL is placed in the medium category, as it requires widespread honest participation to support timely inclusion, even if its trust assumption doesn’t align precisely with n/2-of-n.
Collective View Is Needed To Define Safe Layer 1 Gas Limits And Prioritize Key EIPs
Vitalik Buterin proposed that before setting technical limits for Ethereum, it’s important to first define the purpose those limits are intended to serve. Some of the potential objectives include ensuring that fixed costs remain low enough to support a competitive and inclusive validator market, and that energy consumption stays within a range—approximately 15 kW—that makes it feasible to operate nodes from a residential setting. This would reduce dependence on large data centers, which pose censorship risks due to their centralized nature.
Another more complex consideration is internet connectivity—particularly bandwidth and latency. While adequate internet performance is essential for global decentralization and resilience against censorship, setting a reasonable threshold is not straightforward. Unlike hardware, there is no standard benchmark for internet access; availability varies widely by location, and high-speed connections may simply not exist in many regions. Moreover, internet access can be disrupted more easily than physical infrastructure and is vulnerable to monopolies or overreliance on specific providers, such as satellite-based systems like Starlink. Therefore, Vitalik Buterin suggested a more conservative approach when defining bandwidth requirements compared to hardware limitations.
He also acknowledged that these ideas are still preliminary. Key figures and assumptions are yet to be finalized, and certain components—such as FOCIL, a proposed mechanism for fast block inclusion—remain under debate. While some in the Ethereum community support it strongly, others have yet to engage with the concept. If FOCIL is ultimately not implemented, that decision could influence the network’s design strategy, particularly around optimal block construction.
Vitalik Buterin emphasized the importance of reaching a clear, shared understanding within the community on these decentralization-related questions. He noted that such clarity is essential for determining safe limits for Layer 1 gas usage and for identifying which Ethereum Improvement Proposals (EIPs) are most important to prioritize to maximize the gaslimit/decentralization tradeoff curve.
