Base vs Starknet

Which is more decentralized — Base or Starknet? A side-by-side on consensus, nodes, clients and governance.

	Base	Starknet
Grade	C	C
Type	L2 · Optimistic rollup	L2 · ZK rollup
Nakamoto / stage	Stage 1	Stage 1
Node / validator set	Inherits Ethereum security	Inherits Ethereum security
Clients / sequencer	Single sequencer (Coinbase)	Single sequencer (StarkWare)
Governance	Coinbase-led + Superchain	Starknet governance (token + council)
Key risk	Coinbase-run sequencer	Centralized sequencer

Base C

L2BEAT Stage 1
Massive adoption & liquidity
Backed by the OP Stack roadmap

Sequencer run by Coinbase (single regulated operator)
No token / foundation-style governance

Starknet C

Validity proofs (no challenge window)
L2BEAT Stage 1
Native account abstraction

Centralized sequencer & prover
Smaller ecosystem than OP/Arbitrum

Bottom line

Stage-1 guarantees with a notably centralized, Coinbase-operated sequencer. Strong cryptographic guarantees; operational decentralization is in progress.
