Vitalik Buterin, a co-founder of Ethereum, recently voiced concerns about the burgeoning Layer 2 (L2) projects, suggesting they compromise Ethereum’s long-term vision. In his statement on social media platform X, he highlighted that many new networks rely on existing templates rather than fostering technical innovation, impeding the broader ecosystem’s development. Addressing a U.S.-based developer community, he targeted EVM-compatible chains created through a “copy-paste” approach. According to Buterin, original architectures are necessary for Ethereum to achieve its scalability goals, rather than superficial solutions.
Critiques of Replicated L2 Models
In his post dated February 5, Vitalik Buterin argued that most new L2 networks emerge from habit and comfort, not technical necessity. Developers often choose to build chains based on the Ethereum Virtual Machine, adding a simple “optimistic bridge” and launching them without significant innovation. He likened this trend to the past “Compound forking” spree prevalent in DAO governance.
Buterin argued that this repeated practice stifles creativity and limits the industry’s imaginative potential. He stated that superficially connected networks offer no real scalability benefits to Ethereum, pushing the ecosystem toward a dead-end. Projects associated with Ethereum solely through branding fail to meet technical expectations, underscoring their weakness in contributing effectively.
The co-founder took a harsh stance against EVM chains lacking an Ethereum bridge. He noted that such projects damage both the ecosystem and user trust, and said there’s no need for new first-layer networks. Buterin reaffirmed that Ethereum’s mainnet continues to expand its block capacity until 2026, emphasizing that the foundational layer is already scaling.
Emphasis on Genuine Connectivity and Security
Buterin’s recent statements resonate with his earlier critiques that some L2 projects fail to fully inherit Ethereum’s security. Many networks profess to be natural extensions of Ethereum but practically maintain weak connections with the main chain. The decline in mainnet fees and the rise in gas limits mean L2s no longer need to operate like “branded shards.”
Buterin advocated for an alignment between the technical reality of projects and the image they project to the public. He stressed the need for “alignment of perception and substance,” criticizing ventures that leverage Ethereum connectivity solely as a marketing tool. He noted that promotions without genuine integration erode the ecosystem’s reliability.
Buterin also shared two viable foundational models, which include prediction market applications managing accounts and settlements on the mainnet while conducting transactions via rollup. Another model involves institutional structures like government registration systems publishing cryptographic proofs for transparency on Ethereum. Although not fully decentralized, these systems need clear positioning, according to Buterin.
