Base vs Optimism Superchain: The Sequencer Divergence
Base remains at Stage 0 decentralization as Coinbase maintains sole sequencer control, while Optimism manages the OP Stack with $2.8 billion in total value locked. This divergence highlights growing differences in governance and network security between the two Layer 2 solutions.
Coinbase’s centralized control
Base remains at Stage 0 because Coinbase operates the sole sequencer. Coinbase abandoned its plan to decentralize through Optimism in February 2026. The decision to abandon the roadmap through Optimism in February 2026 means Coinbase now holds all control rights via its Security Committee and Coordinator multisig wallets, effectively reclaiming the governance authority it previously shared. This consolidation leaves no room for the decentralization promised in 2023. Coinbase originally planned a permissionless fraud proof mechanism for 2023, but this milestone failed to launch on schedule. While Coinbase announced the completion of this milestone in April 2025, current standards still classify the technical level as Stage 0. L2Beat classified Base as Stage 1 in August 2026, but a recent downgrade to Stage 0 confirms the network remains fully controlled. In June 2026, Coinbase modified underlying code and rolled back blockchain data to fix two consecutive network outages. These incidents prove that a single operator controls transaction ordering. Base generated over $75 million in sequencer revenue throughout 2025. I view Base as a centralized distributed database rather than a decentralized network.
Optimism governance and the Superchain
The Optimism Collective manages the OP Stack, which powers the Base network. In January 2026, the Optimism Token House passed a proposal with 84% support to reroute half of the Superchain revenue toward OP token buybacks. This 12-month pilot redirects roughly $49 million in OP tokens away from users. The team that cast the deciding vote for this proposal received funding from the Optimism Foundation. Optimism holds $2.8 billion in total value locked. The decision to redirect funds away from users highlights how closely affiliated entities influence the governance process. Optimism uses a bicameral governance structure that splits decision-making between the Token House and the Citizens’ House.
| Network | Type | TVL | Median Fee |
|---|---|---|---|
| Arbitrum One | Optimistic | $13.8B | $0.04 |
| Base | Optimistic | $11.2B | $0.02 |
| OP Mainnet | Optimistic | $5.6B | $0.03 |
The OP Stack provides a standardized framework for launching Layer 2 and Layer 3 chains. Optimism’s Bedrock upgrade in June 2023 reduced deposit times to under 2 minutes and cut Layer 1 data costs by 40%. Does the concentration of voting power among large holders undermine the goal of public goods funding?
Scaling and usage metrics
Base processed $48,193 in fees over the last 30 days. In Q1 2026, over 90% of onchain agentic stablecoin transaction volume occurred on Base using USDC. Coinbase processed 100 million plus payments through its x402 protocol, and 99% of those transactions used USDC. In Q2 2026, Coinbase captured 10.3% of crypto trading volume market share, a rise from 9.1% in Q1 2026.
| Metric | Base (Q1 2026) | Optimism (Sept 2026) |
|---|---|---|
| Daily Transactions | N/A | 600,000 |
| Agentic Stablecoin Vol | 90%+ | N/A |
Average USDC held in Coinbase products reached $20 billion. You should watch how these centralized sequencers impact your long-term security. While Base holds $11.2 billion in total value locked, it still lacks the liquidity depth of Arbitrum, which holds $5.5 billion. Arbitrum processes over 1.2 million daily transactions through its Nitro upgrade, which introduced a WASM-based execution environment. I notice that while Base captures massive volume, the network remains a single point of failure. I see how Coinbase uses its massive user base to drive volume, but the sequencer risk is real.
