Assessment
OP Mainnet reached Stage 1 and anchors the Superchain. Its sequencer is run by the OP Foundation, but it has the most concrete public plan to share/decentralize sequencing via Espresso and Flashbots. Governance runs through the two-house Optimism Collective.
Decentralized here
- L2BEAT Stage 1
- Concrete shared-sequencing roadmap
- Superchain network effects
- Two-house Optimism Collective governance
Centralization vectors
- Centralized sequencer today
- Foundation influence
- Not yet Stage 2
C+Verdict
Stage 1 with the clearest path to decentralized sequencing.
