Fairness Score
Launch, distribution, and governance fairness
Notes
- *CRITICAL: Relay nodes are PERMISSIONED and controlled by Algorand Foundation. While participation nodes are open to anyone, the relay infrastructure creates a centralized coordination point that can halt network communication.
- *Foundation controls 500M+ ALGO treasury with unilateral spending authority (~100M ALGO per quarter). No community vote required for allocations.
- *go-algorand is the dominant client implementation. Low client diversity compared to Bitcoin/Ethereum creates single point of failure risk.
- *Only Foundation can propose governance votes. Community can vote on proposals but cannot initiate them.
- *Nakamoto Coefficient research (July 2024) shows ALGO performs better than Ethereum 2.0, but Foundation does not publish this metric publicly.
- *Token unlock completed November 2024. All 10B ALGO now in circulation. Insider holdings (~25-35%) decreasing as Foundation distributes treasury.
Chain Score
Technical/economic decentralization
Nakamoto Coefficient
Number of independent entities that would need to collude to compromise the system. Higher is better.
tap to expandValidator/Miner Concentration
Share of top 5 validators/miners in stake/hashrate. Lower concentration is better.
tap to expandClient Independence
Number of independently developed full-node implementations. Measures resilience against single-codebase bugs and single-entity control.
tap to expandNode Geography & Hosting
Geographic distribution of nodes and cloud hosting concentration. Lower cloud % is better.
tap to expandFull Node Decentralization
Number of independent full nodes validating the chain. More nodes = harder to attack, better censorship resistance. For PoW chains, this is separate from miners. For PoS, validators often = nodes.
tap to expandControl Score
Power and control structures
Corporate/Foundation Capture
Is there a dominant company/foundation controlling roadmap, marketing, and hiring? Can the project survive without them?
tap to expandRepo/Protocol Ownership
Distribution of merge rights in core repositories (clients, specs). More distributed is better.
tap to expandBrand & Frontend Control
Who owns brand, domains, main frontends, official wallets/apps? Decentralized ownership is better.
tap to expandTreasury & Upgrade Keys
Composition of treasury/upgrade multisigs and admin keys. More independent signers is better.
tap to expandAdmin Halt Capability
Can a single entity or small group unilaterally halt, freeze, or censor the chain? This is a critical centralization risk.
tap to expandProtocol Immutability
Has the protocol made fundamental rule changes (consensus mechanism, monetary policy, contentious forks)? Immutable rules are a core property of decentralization.
tap to expandFairness Score
Launch and distribution fairness
Launch Fairness / Premine
Team/VC/Foundation premine and launch model (fair launch vs. sale/IDO). Less premine is better.
tap to expandToken Concentration
Share of circulating supply held by insiders (team/VC/foundation). Less concentration is better.
tap to expandGovernance Control
Share of governance voting power held by insiders. 100% = no token governance (team decides everything). Less insider control is better.
