Four-Pillar Breakdown
| Pillar (weight) | Score | Nakamoto Coeff | Key Finding |
|---|---|---|---|
| Infrastructure (30%) | 58/100 | 19 | 1,900 validators but heavy Hetzner / OVH reliance |
| Capital (25%) | 48/100 | 2 | High insider allocation; vesting concentration |
| Governance (25%) | 55/100 | 0 | Foundation-driven roadmap; limited on-chain gov |
| Software (20%) | 50/100 | 2 | Agave + Firedancer (in rollout) — duopoly forming |
Composite = 0.30(58) + 0.25(48) + 0.25(55) + 0.20(50) = 53.2.
Infrastructure & Outage Exposure
Solana’s throughput is unmatched, but it pays for it in concentration. Infrastructure exposure is the highest in the set — roughly 45% AWS — and a large share of validators run on Hetzner/OVH, meaning the network depends heavily on a handful of hosting providers. This is the root of the network’s historical outage vulnerability.
What the Score Means
- Infrastructure (58): 1,900 validators is a healthy count, but provider and (importantly) hosting concentration lowers resilience to cloud or ISP events.
- Capital (48): insider and vesting concentration is high, with a Gini of ~0.88.
- Software (50): a two-client duopoly is forming as Firedancer rolls out — better than one, still thinner than Ethereum.
Solana’s score has climbed from ~35 (2020) toward ~55 (2025) as reliability and client work matured. Track the timeline in the Terminal.
Frequently Asked Questions
Is Solana decentralized?
Partially. It has many validators but concentrates heavily in hosting providers and features limited on-chain governance, giving it a lower score than Ethereum or Bitcoin.
Why is Solana’s decentralization score lower?
Three factors: heavy AWS/Hetzner infrastructure reliance, high capital/vesting concentration, and a small client set.
Has Solana’s decentralization improved?
Yes — from a low base. Firedancer’s rollout and reliability fixes have nudged the composite up each year, but it still trails the leaders.
Final Verdict
Solana trades decentralization for raw performance. It is meaningfully faster and cheaper, but scores lowest in infrastructure concentration and capital distribution among major chains. For those who value throughput over resilience, this is the key trade-off.
