A Stage 1 OP Stack rollup with huge adoption — but a sequencer run by Coinbase.

- How it works
- OP Stack optimistic rollup on Ethereum with Stage 1 exit guarantees. The sequencer is operated by Coinbase, and Base relies on the OP Stack / Superchain for its decentralization roadmap.

Assessment
Base is one of the largest L2s and reached L2BEAT Stage 1, so users keep forced-exit guarantees. Its sequencer is run by Coinbase, a regulated single operator — strong for reliability, weaker for credible neutrality until shared sequencing lands.
Decentralized here
- L2BEAT Stage 1
- Massive adoption & liquidity
- Backed by the OP Stack roadmap
- Reliable, well-run infrastructure
Centralization vectors
- Sequencer run by Coinbase (single regulated operator)
- No token / foundation-style governance
- Not yet Stage 2
CVerdict
Stage-1 guarantees with a notably centralized, Coinbase-operated sequencer.
