Ethereum Developers Unveil Native Rollups Prototype That Eliminates ZK Proofs

The Ethrex client team, in collaboration with Ethereum Foundation and analytics platform L2BEAT, has published code and documentation for a working proof-of-concept implementation of native rollups. The approach allows Ethereum's mainnet to verify Layer 2 operations directly, without relying on ZK proofs or fraud proofs.

"We've been working with @kevaundray and @ladislaus0x from @ethereumfndn and @donnoh_eth from @l2beat on a proof of concept of EIP-8079 (native rollups) using @ethrex_client. Native rollups reuse Ethereum's own execution to verify L2 state transitions. No ZK circuits, no fraud…" — ethrex (@ethrex_client), original post

How the EXECUTE Precompile Works

The prototype implements EIP-8079 using the Ethrex client and introduces a new mechanism called the EXECUTE precompile. This component re-executes L2 blocks directly on the mainnet, enabling the base layer to independently recalculate state and confirm the validity of all operations.

Currently, every rollup in the Ethereum ecosystem relies on either fraud proofs or cryptographic ZK schemes to validate transactions. Despite their technical complexity, these methods have become industry standards. Native rollups propose a fundamentally different path: the base layer handles verification itself, removing the need for any external proof mechanisms.

Why It Matters

If native rollups prove viable in practice, the implications for Ethereum's architecture could be significant. Rollups would directly inherit the security guarantees of the main network. Any upgrade to the base protocol would automatically propagate to Layer 2 solutions, dramatically simplifying their long-term maintenance and support.

The demonstration on the Ethrex client highlights a potential evolution in design: some verification logic could migrate back to the base layer. However, this remains purely experimental at this stage. The current implementation is a proof of concept, not production-ready infrastructure. Native rollups are still firmly in the research phase.

Context: Rethinking Ethereum's Scaling Strategy

The experiment fits within a broader reassessment of Ethereum's scaling approach. Co-founder Vitalik Buterin previously stated that the rollup-centric roadmap remains intact, but acknowledged that L2 ecosystem decentralization has been progressing more slowly than anticipated.

Earlier in March, Buterin also urged developers to experiment more aggressively at the application layer without compromising the protocol's core principles. The native rollups prototype represents a tangible step in that direction, showing the community's willingness to explore alternative approaches to L2 transaction verification.

The published code and documentation are now available for other teams to study and test independently. The future trajectory of EIP-8079 will depend on further research findings and feedback from ecosystem developers.
