Circle xStock Heat Score: history and how it is built

The Heat Score measures how much real human conversation a coin has compared with its own recent past. It is not price, not market cap and not raw engagement.

How Heat Score v0 works

Start at 50. Add points when today's unique contributors beat their 7-day median (weight 22 per doubling) and when the last 7 days beat the 30-day median (weight 12); do the same for interactions with lower weights (8 + 8). Subtract a penalty when the share of posts flagged as spam exceeds 15%. Clamp between 0 and 100. Labels: Cold <35, Warm 35-54, Hot 55-74, On fire 75+.

Why contributors first? A handful of accounts can farm millions of interactions; thousands of distinct people posting is much harder to fake. Contributor and spam data come from LunarCrush.
