Vitalik Buterin's Take on Layer 3 Networks: Is This the Future of Blockchain?

Vitalik Buterin, the co-creator of Ethereum, recently revisited the topic of Layer 3 networks, stressing that they do not automatically enhance throughput. Buterin shared an article he penned about 18 months ago, highlighting how L3 networks can mitigate certain fixed costs related to batch publishing and transactions.

Vitalik Buterin Calls for Exploration of More Cost-Effective Alternatives to Layer 3 Networks

Buterin suggests exploring alternative, less burdensome methods to achieve similar cost savings as those offered by L3 networks. He underscores that while L3 networks provide advantages, there are potentially lighter approaches to cost reduction.

In his article, Buterin keeps the debate about the classification of L3 and L2 networks open. He argues that defining these classifications prematurely is unwarranted, especially given the evolving architecture of the multi-rollup ecosystem.

Marc Boiron, CEO of Polygon, Argues for the Value Transfer of L3 Networks to Supporting L2s Amid Debate

Polygon CEO Marc Boiron presents a contrasting view, asserting that L3 networks primarily siphon value away from Ethereum onto the L2 networks they support. However, his perspective is contested by those who argue that L2 networks inherently contribute value to Ethereum.

The discourse surrounding L3 networks involves various stakeholders. Notable entities in this space include Orbs, Xai, zkSync Hyperchains, and the recently introduced Degen Chain on Arbitrum Orbit. Despite their presence, it's essential to recognize that this sector remains relatively niche.
