Enhancing Composability in Ethereum's Layer 2 Solutions

Martin Köppelmann, co-founder of Gnosis, has proposed that Ethereum should have native rollups—a vision aimed at addressing scalability and decentralization.

Köppelmann critiques the current state of layer 2 solutions, highlighting their limitations in fully inheriting Ethereum’s security and composability. 

He proposes a bold alternative: 128 Ethereum-native rollups designed to expand block space, strengthen alignment with Ethereum’s core principles, and ensure long-term viability for developers and users.

Plus, Martin tackles the controversies: Are L2s parasitic? Could native rollups spell the end for existing solutions? And why should they rely on zero-knowledge proofs instead of Optimism?

Show highlights:

• Whether the Ethereum scaling roadmap is accomplishing its goals
• Why based rollups are not a full solution, according to Martin
• What Martin proposes instead
• Why Martin is proposing these rollups to be ZK-rollups instead of optimistic
• Whether the proposed solution would focus on privacy
• What it is about chain abstraction that Martin doesn’t like
• How he envisions that these native rollups will solve many composability issues across L2s
• Whether the community has embraced this proposal and how likely it is to be implemented
• What would happen to current L2s if native rollups get implemented
• Why despite being against the current state of L2s, Martin says that they are not parasitic to Ethereum
