Back to: Certified Decentralization Analyst
Before you start citing composite scores, you need to understand how they’re built — and their honest limitations. This lesson is the analyst’s code of conduct.
The composite formula
“` composite = 0.30·infrastructure + 0.25·capital + 0.25·governance + 0.20·software “`
Those weights are a judgment call, not a law of physics: – Infrastructure gets the most weight because a chain you can’t run is decentralised in name only. – Capital and governance are close behind — they decide *control*. – Software gets 20%: rare but catastrophic.
Changing the weights changes the ranking. BTC stays top under most weightings; XRP and Aptos stay low; the middle (Solana/Sui/Avalanche) shuffles. Always state which weights you used when quoting scores.
What the data is not
– Not real-time. Validator sets, stake splits, and client mix change; the audits are refreshed periodically. – Not exhaustive. No methodology measures everything (social concentration, regulatory jurisdictions, off-chain dependencies). – Not a price prediction. Decentralization is a security property, not a thesis about token value (protocols with low scores can still be useful).
Best practices when you quote W3D data
1. Link the methodology — let people verify the formula. 2. Name the pillar, not just the composite. “BTC 84.8” is a headline; “Bitcoin’s software pillar is 70 because Core dominates ~95%” is analysis. 3. Give the date. Data ages fast in this space. 4. Prefer the CC0 dataset so anyone can re-run your math.
How to challenge a score (and be right)
The whole point of open methodology is that a score is a *hypothesis* you can test. To argue “ETH should be an 82 not an 80.8”:
– Point at the specific pillar that’s wrong. – Bring newer data (validator share, client usage, a governance change). – Update the relevant `content/chains/*.md` + `data/chains.csv` in a PR — that’s the mechanism this repo is built on.
The final skill of an analyst is *epistemic humility*: knowing exactly which
> parts of the number are measurement and which are judgment.
