Four-Pillar Breakdown
| Pillar (weight) | Score | Nakamoto Coeff | Key Finding |
|---|---|---|---|
| Infrastructure (30%) | 75/100 | 97 | 297 active validators, geographically diverse |
| Capital (25%) | 64/100 | 9 | Web3 Foundation + early backers retain weight |
| Governance (25%) | 82/100 | 0 | OpenGov on-chain referenda; one of the most active |
| Software (20%) | 68/100 | 2 | Polkadot SDK / Substrate; multiple node implementations |
Composite = 0.30(75) + 0.25(64) + 0.25(82) + 0.20(68) = 72.6.
Infrastructure & Outage Exposure
Polkadot posts the highest infrastructure Nakamoto Coefficient in the set (97), reflecting a small but extremely dispersed validator set that is hard to compromise. Its hyperscaler exposure is moderate (about 30% AWS), and the geographically diverse validators give it strong resilience to any single region or provider.
What the Score Means
- Governance (82): OpenGov delivers genuinely active on-chain referenda — among the most functional governance in crypto.
- Infrastructure (75): extremely hard for any party to capture, though the validator count is capped by the NPoS design (297).
- Capital (64): Web3 Foundation and early backers retain notable weight in token economics.
Polkadot rose from ~45 (2020) to ~73 (2025), driven mainly by OpenGov go-live. See the timeline in the Terminal.
Frequently Asked Questions
Is Polkadot decentralized?
Yes, strongly — it has one of the most active on-chain governance systems and a highly dispersed validator set, though the validator count is capped by design.
Why is Polkadot’s Nakamoto Coefficient so high for infrastructure?
Its 297 validators are geographically diverse, so 97 independent parties would need to be compromised together to threaten that subsystem.
How does Polkadot compare to Ethereum on decentralization?
Polkadot trails slightly overall (72.6 vs 80.8) but beats Ethereum on governance activity and infrastructure capture-resistance.
Final Verdict
Polkadot is a decentralization leader on governance and infrastructure capture-resistance, held back mainly by capital concentration and a modestly-capped validator set. It ranks near the top of the audited networks.
