Ethereum researchers demo ‘native rollups’ prototype that could simplify Layer 2 verification
Researchers demonstrated a 'native rollups' prototype that simplifies L2 verification by re-executing transactions on Ethereum's base layer.Summary
Ethereum researchers, including developers from Ethrex, have demonstrated a proof-of-concept for "native rollups," a scaling design intended to simplify Layer 2 verification. This approach, implemented using EIP-8079 and a new EXECUTE precompile, avoids traditional methods like zero-knowledge circuits or fraud proofs by re-executing Layer 2 blocks directly on the Ethereum base chain. This allows the base layer to confirm validity by recomputing state changes using Ethereum's own state transition function. The prototype shows the full lifecycle, including deposits and withdrawals verified via state proofs. Developers suggest this could reduce complexity and allow L2s to inherit security upgrades automatically from Ethereum, aligning with recent discussions where Vitalik Buterin encouraged broader experimentation in Ethereum's scaling architecture.
