Ethereum co-founder Vitalik Buterin has proposed a new framework for Layer-2 (L2) rollup security that could bring faster finality and stronger trust guarantees to Ethereum’s scaling ecosystem.
In a recent proposal, Buterin outlined a roadmap built around a hybrid-proof architecture that combines zero-knowledge proofs, optimistic rollups, and trusted execution environments (TEEs) while avoiding overreliance on any single system.
The proposal arrives as Ethereum’s L2 landscape matures. Several rollups have reached Stage 1 on Ethereum’s scaling roadmap, and upcoming upgrades — like Pectra and Fusaka — are expected to significantly expand the availability of data blobs for rollup use.
Buterin said the focus is now on pushing these rollups to Stage 2, which requires a higher degree of trustlessness and faster transaction finality. In the short term, he believes the most robust approach is a three-prover system, where two out of…
