Ethereum researcher Justin Drake discusses "native rollups", which are expected to achieve trustless scaling

On January 23, Ethereum researcher Justin Drake posted on the ethresearch forum to discuss a new rollup design called "native rollups". In short, it relies on Ethereum L1 validators for proofing, i.e., state transition functions and verification. This contrasts with Optimism Rollup (such as Optimism, Arbitrum) or zk-Rollup (such as Starknet, ZKsync), which push the computational burden of execution to L2 and then rely on fraud or zk proof systems to generate state roots and proofs before returning back to the main network.

Drake's proposal suggests introducing "execution" precompiles (hardcoded functions in EVM) that will verify user transactions' EVM state transitions. Native rollups have achieved two breakthroughs: there is no longer a need for investment in and maintenance of expensive miner prover networks and dedicated GPU hardware because proofs will be handled and executed by L1 validators; there is no longer a need for maintaining complex governance structures including trusted security committees approving contract upgrades to achieve EVM equivalence. All these are made possible by inheriting the security of Ethereum L1 making native rollup "trustless".
