Ethereum researchers propose "native Rollups" PoC, which will directly verify layer two states on the base layer

According to The Block, Ethereum researchers demonstrated a proof of concept for "native Rollups" based on the execution client Ethrex, implementing EIP-8079 through the addition of an EXECUTE precompile, which directly replays and verifies Layer 2 block state changes on the Ethereum base layer.

This solution does not rely on zero-knowledge proofs or fraud proofs, but instead is executed and confirmed by Ethereum itself to validate Rollup transaction validity. The related contracts are used to track Rollup state, bridge cross-layer messages, and verify withdrawals based on Merkle-Patricia proofs. Developers claim that native Rollups can simplify long-term maintenance of Layer 2, allowing them to directly inherit Ethereum's security and upgrade properties, and they are still in the exploration and proof of concept stage.
