Address attribution sources

Every label on this site traces to a named source with a known method and a confidence we picked deliberately. 15 sources, 9,097 rows live in the database right now.

How to read this page. Confidence is a number we assign, not the source's own claim. Direct-disclosure sources (exchange proof of reserves, OFAC, in-house curated) get 1.0. Reputable scrapes (WalletExplorer) get 0.85. Community-curated registries get 0.7 to 0.95 depending on per-entry citation. We carry per-entry confidence where the upstream supplies it.

How we pick confidence

Confidence governs what wins when two sources disagree on an address. The /address aggregator surfaces every row, but the headline label comes from the highest-confidence source. Where two 1.0-confidence sources agree, the address page shows an explicit corroboration badge. Cross-source agreement analytics live at /analytics/cross-source.

We never fabricate confidence: every value here mirrors a deliberate choice in the loader code. If a source's quality changes (a community feed gets noisier, a research dataset gets retracted), we adjust the value and the change propagates to every page on the next deploy.
