How a price feed forms

Every ~90 seconds, around 100 independent providers each submit a price for BTC/USD. Flare combines them into one number — the weighted median — and measures how tightly everyone agreed. Here it is, live.

Seraphim FTSO submission

Reading the picture

• The gold line is the consensus median — Flare's answer for the price that round.
• The inner band is the interquartile range (IQR): where the middle half of providers (by weight) landed. A thin band means strong agreement.
• The outer band is the wider secondary reward band.
• Switch to % deviation to see the spread in parts-per-million — often just a few cents on a $60,000 price.
• Bright dots are Seraphim FTSO's own submission each round. Hugging the gold line = accurate.
