Polygon CEO Sparks Debate Over Ethereum’s L3s

Polygon CEO sparks debate over ethereum's layer-3 networks

Polygon CEO, Marc Boiron, stirred up controversy over the weekend with his remarks on layer-3 (L3) networks, sparking a heated debate within the crypto community. Boiron argued that L3 networks, which are built on top of layer-2 (L2) scaling solutions for Ethereum, are unnecessary and serve only to drain value away from the Ethereum mainnet.

In a statement on April 1st, Boiron asserted that Polygon Labs, Polygon's layer-2 scaling network, does not focus on layer-3 solutions as they are deemed redundant for scaling existing networks. He suggested that L3 networks are designed to siphon value away from Ethereum onto the L2 networks they are built upon.

However, Boiron's stance faced criticism from some respondents who argued that L2 solutions are integral to Ethereum's value proposition. Boiron partially agreed but contended that L2 value does not equate to Ethereum's value, highlighting the potential risk to Ethereum's security if all L3 networks are funneled value away from the main net.

Polygon's mission, according to Boiron, is to scale Ethereum by leveraging the parallelization of the Ethereum Virtual Machine (EVM) and ensuring privacy, which he believes L3 networks are incongruent with.

Layer-3 protocols, situated atop L2 solutions, are instrumental in hosting application-specific decentralized applications (DApps) that offer a myriad of scaling, performance, interoperability, customization, and cost solutions. Notable players in the L3 ecosystem include Orbs, Xai, zkSync Hyperchains, and the recently launched Degen Chain on Arbitrum Orbit.

Despite the potential benefits of L3 networks, concerns persist regarding their impact on Ethereum's value and security. Peter Haymond, a senior partnership manager at Offchain Labs, pointed out various advantages of L3 networks, such as low bridging costs from L2 to L1, cost-effective on-chain verification, custom gas tokens, and specialized state transition functions.

Contrary to Boiron's views, Patrick McCorry from the Arbitrum Foundation expressed surprise at the dismissal of L3 networks, emphasizing their potential to enhance L2 solutions and streamline Ethereum's settlement processes. He highlighted the importance of Ethereum serving as a global ordering service and final judge of settlement, facilitated by the integration of L3 networks.

In a separate post on X, Helus Labs CEO, Mert Mumtaz, echoed Boiron's sentiments, describing L3 networks as centralized servers settling on other centralized servers (L2s), controlled by Multisigs. Mumtaz's remarks underscore the ongoing debate surrounding the role and impact of L3 networks within the Ethereum ecosystem.

The discourse sparked by Boiron's comments sheds light on the complexities surrounding Ethereum's scalability solutions and the divergent perspectives within the crypto community. While some advocate for the integration of L3 networks to bolster Ethereum's efficiency and functionality, others remain wary of their potential implications for decentralization and network security.


As Ethereum continues to evolve and confront scalability challenges, finding a balance between innovation and risk mitigation remains paramount. The ongoing dialogue surrounding L3 networks underscores the need for thoughtful consideration and collaborative efforts to navigate the intricacies of blockchain scalability and ensure the long-term sustainability of decentralized ecosystems.
