Introduction
A recent study by Klaytn Foundation evaluates the openness of eleven major Proof-of-Stake (PoS) blockchains, highlighting their comparative strengths, weaknesses, and pathways to enhance accessibility. This analysis provides actionable insights for public blockchains aiming to improve decentralization and participation.
What Is Blockchain Openness?
Openness parallels decentralization but emphasizes accessibility—measuring how easily anyone can:
- Join as a validator
- Create/verify blocks
- Contribute to network security
- Resist attacks
Unlike decentralization (which assesses distribution of control), openness evaluates barriers to entry and economic sustainability.
Key Metrics for Measuring Openness
The study proposes five criteria:
- Validator count – Higher numbers indicate broader participation.
- Initial capital cost – Lower costs improve accessibility.
- Capital concentration – Even distribution reduces centralization risks.
- Operating costs – Sustainable expenses encourage long-term validator engagement.
- Economic stability – Resilience against market volatility and attacks.
Comparative Analysis of PoS Blockchains
The study examined these eleven chains (alphabetically):
- Algorand
- Aptos
- Avalanche
- BNB Chain
- Celo
- Cosmos Hub
- Ethereum
- Near
- Solana
- Klaytn
- Polygon
Top Performers in Openness
Algorand, Avalanche, Celo, and Solana scored highest due to:
👉 Low entry barriers for validators
- Balanced capital requirements
- Distributed validator networks
- Economic incentives for participation
Moderately Open Chains
Cosmos Hub, Ethereum, and NEAR Protocol showed mid-range openness, with room to improve validator accessibility and cost structures.
Challenges for Low-Scoring Chains
Aptos and BNB Chain faced criticism for:
- High initial capital costs
- Centralized validator pools
- Limited economic resilience
Klaytn and Polygon, currently permissioned networks, scored low but have transitional pathways. Their focus on scalability and security requires rebalancing for permissionless openness.
Transitioning from Permissioned to Permissionless
For networks like Klaytn, success hinges on:
- Consensus model choice: Stake-based vs. validator-count-based.
- Validator setup: Optimizing numbers, costs, and capital distribution.
- Economic design: Staking ratios and circulating supply stability.

Key Takeaways
- Openness requires low barriers, broad participation, and economic durability.
- Permissionless networks with high capital demands resemble permissioned systems in accessibility.
- Transition strategies must prioritize validator inclusivity and network resilience.
FAQs
Q: How does openness differ from decentralization?
A: Decentralization measures control distribution; openness evaluates access to participation (e.g., validator eligibility).
Q: Which blockchain scored highest in openness?
A: Algorand, Avalanche, Celo, and Solana led in accessibility metrics.
Q: Can permissioned chains become truly open?
A: Yes, but it requires redesigning consensus, validator economics, and capital distribution.
Q: Why do Aptos and BNB Chain rank low?
A: High entry costs and validator centralization limit their openness.
Conclusion
This study underscores the importance of democratizing blockchain participation. Networks prioritizing low-cost entry, decentralized validation, and economic stability will lead the next wave of Web3 adoption. For developers and validators, selecting chains aligned with these principles ensures long-term viability.
