Ethereum co-founder Vitalik Buterin has revised his vision for Layer-2 networks, arguing they aren't truly scaling Ethereum. He believes the original plan, which positioned Layer-2s as the primary scaling solution, is outdated. Buterin's perspective stems from recent developments within the Ethereum ecosystem, prompting a reassessment of Layer-2's role.

Buterin's shift in thinking is due to slower-than-expected decentralization progress among Layer-2s and Ethereum's direct scaling efforts on Layer-1. He emphasizes that scaling Ethereum means creating ample block space, fully backed by Ethereum's security. Networks connected to Ethereum via multisig bridges don't meet this definition, in his view.

Instead, Buterin suggests viewing Layer-2s as a spectrum, offering different trade-offs. He encourages them to focus on value beyond basic scaling, such as privacy features or application-specific design. This could mean a shift in strategy for many Layer-2 projects, potentially impacting their future development and user expectations.

Ultimately, Buterin's comments highlight the evolving nature of blockchain scaling solutions. It signals a move away from the initial rollup-centric roadmap. Layer-2 projects will need to adapt, focusing on specific value propositions beyond simply increasing transaction throughput. The future likely involves a blend of solutions.
