A new proposal outlines a fee structure for Ethereum's EXECUTE-precompile that would ensure sustainable value accrual for ETH in a rollup-centric future. The proposal includes mandatory registration, sequential verification, and proportional fee extraction based on L2 usage.

A research proposal explores scaling Ethereum through enshrined native L2s that share Ethereum's validator set, combined with stateless block building to enable horizontal scaling without increasing hardware requirements.

Researchers identify a new variant of the staircase attack on Ethereum's proof-of-stake system where Byzantine validators can cause honest validators to suffer penalties despite following protocol rules. The attack requires controlling 33% of stake and specific timing conditions.
