The Herfindahl-Hirschman Index (HHI) sums the squared supply share of every holder and scales it to 0–10,000 — a standard market-concentration measure (used by competition regulators) applied to QRL holdings, drawn as one continuous line from the original Proof-of-Work chain into QRL 2.0. Squaring the shares means a few very large wallets dominate the score, so HHI reacts sharply to whale concentration. Below 1,000 is unconcentrated; above 2,500 is highly concentrated.

What is the HHI?
The Herfindahl-Hirschman Index is a standard concentration measure — competition regulators use it to judge market concentration. Here it sums the squared percentage share of every QRL holder and scales the result to 0–10,000. Because shares are squared, large wallets count far more than small ones, so the index is sensitive to whale concentration.
How do I read the value?
As a rough guide borrowed from antitrust practice: below 1,000 is considered unconcentrated, 1,000–2,500 moderately concentrated, and above 2,500 highly concentrated. On a chain with one dominant wallet the HHI can run much higher. As with the other concentration metrics, the trend over time is more informative than any single reading.
Why show HHI as well as Gini?
They emphasise different things. The Gini coefficient captures inequality across the whole distribution including the dust tail, while HHI — by squaring shares — is dominated by the largest holders and barely moves for small wallets. HHI is therefore a sharper whale-concentration signal; Gini is a broader inequality signal.
