Attacking an Ethereum L2 with Unbridled Optimism
This is a concerning aspect of Ethereum&#x27;s strategy to push scaling to layer-2 networks: Ethereum is a heavily audited and tested protocol that runs an extremely decentralized network of diverse clients. L2s can be...an AWS instance running arbitrary buggy code. Much of the confidence in the &quot;base layer&quot; that people using Ethereum currently experience will be significantly undermined if mundane transactions wend in and out of different L2s.
