Four-Pillar Breakdown
| Pillar (weight) | Score | Nakamoto Coeff | Key Finding |
|---|---|---|---|
| Infrastructure (30%) | 84/100 | 3 | 8,200+ beacon nodes; relays still concentrated |
| Capital (25%) | 72/100 | 4 | Lido + top CEX stakers control >40% of stake |
| Governance (25%) | 80/100 | 0 | Off-chain rough consensus via EIPs / All-Core-Devs |
| Software (20%) | 88/100 | 2 | Geth ~52%, Nethermind, Besu, Erigon, Reth |
Composite = 0.30(84) + 0.25(72) + 0.25(80) + 0.20(88) = 80.8.
Infrastructure & Outage Exposure
Ethereum’s client-diversity strength is real — no single implementation holds a dangerous majority (Geth is ~52% but four more clients are well represented). Its exposure is moderate: roughly 32% AWS and 13% GCP. The main infra caveat is that block-building relays remain concentrated, a known centralization vector after the Merge.
What the Score Means
- Software (88): the industry’s best example of client diversity — a single-client bug would not halt the chain.
- Capital (72): the weak pillar; Lido plus top exchange stakers exceed 40% of staked ETH, a real capture risk that the network tracks closely.
- Governance (80): mature off-chain process (EIPs, All-Core-Devs) that is slower than on-chain governance but resilient.
Ethereum’s score climbed from ~55 (2015) through the Merge (~2022) to ~81 (2025). See the timeline in the Terminal.
Frequently Asked Questions
Is Ethereum decentralized?
Yes — it is among the most decentralized networks, with superb client diversity and a very large validator set. The main watch-item is staking concentration among a few large providers.
What is Ethereum’s Nakamoto Coefficient?
~3 for infrastructure, ~4 for capital (number of entities to control a majority of stake), and ~2 for software clients.
Is staking concentration a real risk?
It is the biggest decentralization risk Ethereum faces in 2026 — Lido and top exchanges hold over 40% of stake, which could approach censorship thresholds if unchecked.
Final Verdict
Ethereum posts the second-highest decentralization grade, powered by unmatched software client diversity and a huge validator set. Its achilles heel is staking concentration. For most builders and users it remains a strongly decentralized, credible network.
