Huge validator set and improving client diversity — dragged down by staking-pool concentration.
L1PoS
- Type
- L1 · PoS
- How it works
- Proof-of-Stake run by ~1M validators across many independent operators, with thousands of nodes. Governance is off-chain rough consensus among client teams, researchers and stakers.
- Nakamoto coefficient
- ~3*
- Node / validator set
- ~1M validators · many node operators
- Client diversity
- Exec: Geth ~41%, Nethermind ~38%, Besu ~16% (improving)
- Governance
- Off-chain rough consensus
- Key risk
- Lido staking share; Geth client lead
Assessment
Ethereum has an enormous validator set and the broadest client diversity of any smart-contract chain — and it has genuinely improved, with no execution client now above two-thirds. Its low Nakamoto coefficient reflects staking-pool concentration (Lido and a few large stakers), not a small node count.
Decentralized here
- ~1M validators across many operators
- Improving client diversity (no client > 2/3)
- Largest decentralized app ecosystem
- Credible neutrality as the L2 settlement layer
Centralization vectors
- Staking-pool concentration (Lido share)
- Geth still the leading execution client
- High solo-staking capital requirement (32 ETH)
BVerdict
Strong on breadth; the work left is reducing staking-pool and client concentration.
