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

Figure Live data — the most recent BTC/USD anchor rounds read from the Flare network, not a schematic. Each round is one commit-and-reveal vote of the whole field.

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 vote weight, landed. A thin band means the field agreed closely that round.
The outer band is the wider secondary reward band, a fixed half-width set per feed by governance.
Switch to % deviation to see the spread in parts per million, which is how the protocol actually measures it — the absolute price hides how small the disagreement is.
The bright dots are our own submission each round. The closer they sit to the median line, the more rounds we score inside the bands.

Why the distance matters

That distance is not cosmetic. A submission inside a band earns that band's share of the round's accuracy rewards; a submission outside it earns nothing from that band for that round. Repeated across every 90-second round of an epoch, the difference between a provider that tracks the median and one that drifts is the difference in the reward rate their delegators receive. You can check ours against every other provider on Providers — our row is marked, and it sorts wherever the data puts it.

Curious how landing inside those bands turns into rewards? That's the reward methodology.
