The world of Ethereum scaling solutions is heating up, with Polygon CEO Marc Boiron igniting a debate by criticizing Layer 3 (L3) networks. Boiron argues that L3s exist solely to siphon value away from Ethereum and onto the Layer 2 (L2) networks they’re built upon.
I’ll say the quiet part out loud: L3s exist only to take value away from Ethereum and onto the L2s on which the L3s are built.
*You do not need L3s to scale*
And this is why Polygon Labs does not work on L3s.

Polygon, itself a prominent L2 solution for Ethereum, contends that existing L2s are sufficient for scaling purposes. They believe introducing L3s creates an unnecessary layer of complexity and undermines the value proposition of the Ethereum mainnet.
Boiron emphasizes the importance of a single, robust L2 solution for Ethereum. If all L3s settled on one L2, he argues, Ethereum wouldn’t capture any value from the transactions, jeopardizing its security.
However, proponents of L3s counter that they offer unique advantages. L3s can be even more specialized and efficient than L2s, catering to specific use cases within the Ethereum ecosystem. Additionally, some argue that a diverse scaling solution landscape fosters innovation and competition.
The debate reflects the ongoing challenge of scaling the Ethereum blockchain. While L2 solutions have emerged as a promising approach, the optimal architecture for a scalable and secure Ethereum ecosystem remains a topic of discussion.
The coming months will likely see further developments in this space, with both L2 and L3 solutions vying for dominance. It remains to be seen which approach will ultimately prove most successful in facilitating the growth and adoption of the Ethereum network.
