Four-Pillar Breakdown
| Pillar (weight) | Score | Nakamoto Coeff | Key Finding |
|---|---|---|---|
| Infrastructure (30%) | 92/100 | 4 | 17,800+ reachable nodes across 100+ countries |
| Capital (25%) | 78/100 | ~1,900,000 | Gini ~0.83; top wallets are exchanges, not individuals |
| Governance (25%) | 95/100 | 0 | No on-chain governance; rough consensus + BIPs |
| Software (20%) | 70/100 | 1 | Bitcoin Core dominates ~95%; Knots & btcd minority |
Composite = 0.30(92) + 0.25(78) + 0.25(95) + 0.20(70) = 84.8.
Infrastructure & Outage Exposure
Bitcoin’s node base is the most geographically dispersed in crypto, which is why its infrastructure pillar scores highest. Its reliance on hosting providers is comparatively low: roughly 18% AWS, 7% GCP, and 55% ISP exposure. This makes Bitcoin the most resilient network in the set to any single cloud or ISP outage.
What the Score Means
- Governance (95): no single entity can change Bitcoin’s rules — change requires rough consensus and Bitcoin Improvement Proposals across the wider community.
- Capital (78): the main caveat is concentration among exchange-owned wallets, though no party controls a network-threatening share of hash power.
- Software (70): the one weak pillar; Bitcoin Core’s ~95% dominance means a severe Core bug could be systemic, though diverse node coverage softens the risk.
Over time Bitcoin’s score has risen from ~40 (2009) to ~89 (2025) as node distribution deepened — see the timeline in the Terminal.
Frequently Asked Questions
Is Bitcoin decentralized?
Bitcoin is the most decentralized major network by node distribution and governance — it has no central authority and thousands of independent nodes worldwide.
What is Bitcoin’s Nakamoto Coefficient?
It varies by subsystem: ~4 for infrastructure (independent parties to disrupt node/hash distribution meaningfully), and roughly 1 for software (a single dominant client). This is why the composite treats each pillar separately.
Why does Bitcoin’s capital score lag?
Wealth is skewed toward exchange custodians, lifting the Gini concentration metric even though no single holder poses a threat to the network.
Final Verdict
Bitcoin earns the highest decentralization grade in the audited set, driven by unmatched node distribution and permissionless governance. Its only structural weakness is software client concentration. Overall it remains the standard against which every other network’s decentralization is measured.
