Ethereum researchers have demonstrated an early prototype of “native rollups” that could shift how Layer 2 networks verify transactions. The concept allows Ethereum to directly re-execute rollup blocks on the base chain, potentially simplifying a core piece of the network’s scaling architecture.
The proof-of-concept implements EIP-8079 using the Ethrex client and introduces a mechanism called the EXECUTE precompile. Developers from the Ethereum Foundation worked alongside contributors from L2BEAT to publish code demonstrating a working environment for the model.
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.

Could Native Rollups Replace Today’s Proof Systems?
Most current Layer 2 networks rely on either fraud proofs used by optimistic rollups or cryptographic validity proofs generated by zero-knowledge systems. Native rollups take a different approach. Instead of verifying proofs, Ethereum would recompute the Layer 2 transactions itself by replaying rollup blocks through the EXECUTE precompile.
The prototype demonstrates the full lifecycle of such a system. Layer 2 blocks are submitted to Ethereum, executed onchain, and their state changes confirmed by the base layer. Deposits can move assets to the rollup, cross-layer contracts can interact, and withdrawals are verified through Merkle Patricia state proofs.
This architecture could simplify the operational stack required for rollups. According to ecosystem data from L2BEAT, Layer 2 networks currently secure tens of billions of dollars in value across multiple proof systems and verification models. Could a single verification path tied directly to Ethereum reduce that complexity over time?
Researchers stress that the current implementation remains experimental and not production infrastructure. Yet the model illustrates how rollups might inherit upgrades and security properties directly from the base chain without maintaining independent verification frameworks.
The experiment arrives amid ongoing debate about Ethereum’s long-term scaling strategy. Vitalik Buterin recently noted that while Ethereum’s rollup-centric roadmap remains intact, parts of the Layer 2 ecosystem have decentralized more slowly than expected. The next phase of research will test whether native rollups can evolve from proof-of-concept code into viable infrastructure for Ethereum’s scaling stack.
