Source Mesh

Source coverage

One instrument → many observers → one canonical market state. Market Atlas does not trust a quote: it observes the market through independent paths, counts source families (not URLs), and publishes the consensus with the evidence. This page measures that redundancy and lists where it is still thin.

A family is a group of sources believed to share an upstream (declared, or inferred statistically). Proxies (stablecoin markets, crosses) and validators (restricted-rights sources) confirm a value but never count as independent families. Score = 65 % family attainment + 35 % observation attainment.

Likely shared upstreams

pairs of sources whose values coincide within 2 s on ≥ 92 % of ≥ 120 aligned samples — counted as one family

No pair of sources currently looks like a shared upstream. The lineage engine recomputes every five minutes from live observations.
