## Summary

The author asks how to identify an OP Chain in what they call a "modular mess," given that new L3s built on the OP Stack may not clearly meet the Law of Chains, which requires an Ethereum bridge identical to other OP Chains, a multi-sequencer scheme, and fee revenue accruing to Optimism. The post notes that the Law of Chains (v0.1) does not mention L3s, and it lists seven questions about whether L3s that settle or post data on OP Chains, use single sequencing, or run non-EVM VMs would count as OP Chains. It also raises the concern that many L3s may not justify decentralized sequencing because revenue may be low.
