Vitalik Buterin, co-founder of the Ethereum blockchain, reaffirmed his stance on layer 3 networks, contributing to an ongoing discussion about their utility.

Engaging in the debate surrounding the value of layer 3 (L3) solutions, Buterin referenced a post he made over a year and a half ago. Amidst the online discourse sparked by the usefulness of L3 protocols for the Ethereum ecosystem, various speakers highlighted the potential advantages of these solutions.

Buterin supplemented his position with a link to his article titled "What kind of layer 3s make sense?" published in September 2022. In this piece, Buterin posited that layer 3 networks are not primarily geared towards scaling but rather focus on implementing specialized features for layer 2 solutions.

Layer 3 solutions encompass protocols built on top of existing layer 2 (L2) solutions, intended to augment the scalability and functionality of the main blockchain.

Recently, Polygon Labs CEO Marc Boiron asserted that third-layer networks are unnecessary for scaling Ethereum and may jeopardize the security of the blockchain ecosystem. Boiron emphasized that Polygon Labs does not prioritize the development of such solutions.

The discourse surrounding the value of layer 3 networks commenced prior to Boiron's comments, with developer Potuz highlighting several advantages of such solutions in response to inquiries.
