Through six key metrics, we evaluated the decentralization levels of BTC, ETH, SOL, XRP, ADA, AVAX, and TRX. The results reveal ETH and ADA as the most decentralized, while XRP and TRX remain the most centralized. Our simplified scoring model shows ETH leading the pack, with SOL surprisingly surpassing BTC in decentralization. However, no single blockchain excels across all dimensions—true decentralization requires multi-faceted analysis.
The 6 Pillars of Decentralization Measurement
1. Validator Node Distribution
Quality matters over quantity. Unique validator nodes (those producing blocks) demonstrate real decentralization, as PoW and PoS systems rely on them equally. Sybil attack resistance is crucial here.
2. Client Diversity
Single-client ecosystems resemble one-party political systems—they create centralized gatekeeping for protocol changes. Bitcoin's Core dominance exemplifies this risk.
3. Permissionless Design
Any mandatory authorization elements (like Ripple's validator list) immediately undermine decentralization, regardless of node count.
4. Technical Tradeoffs
Design choices with centralizing effects include:
- High hardware requirements
- MEV vulnerabilities
- Delegated staking pools
- Proposer-builder separation (PBS)
5. Governance Structures
On-chain governance prevents power vacuums that attract bad actors. Its absence leads to opaque decision-making (as seen with Bitcoin's BIP process).
6. Political Decentralization
Founder cults or dominant factions (like TRON's Justin Sun influence) can centralize otherwise-technically decentralized chains.

- SOL over BTC due to better client diversity (despite PoH issues)
- ADA/AVAX tie—Cardano wins technically, Avalanche governance
- XRP/TRX struggle with permissioned elements and client monocultures
FAQ
Q: Why doesn't Bitcoin score higher?
A: Despite its robust PoW security, Bitcoin suffers from client centralization (95% Core usage) and lacks formal governance—leading to contentious hard forks.
Q: Can Solana become more decentralized?
A: Yes, if it reduces hardware requirements and implements planned governance upgrades. Current 5G validator demands limit participation.
Q: How important is client diversity?
A: Extremely. A single client bug could crash the entire network (as happened with Ethereum's 2016 Shanghai DoS attack).
Q: Why include political factors?
A: Human systems naturally form power centers. Ignoring them (like Bitcoin's "Wizards vs. Dragons" divide) gives false decentralization perceptions.
Q: Is 60 points achievable?
A: Theoretically yes, but tradeoffs exist. For example, sophisticated governance might slow technical progress—hence ETH's cautious approach.
