Open Label Directory

Labels map specific Bitcoin addresses to named entities using exact match only. Each entry records a category (exchange, custody, miner, service), a confidence grade (high / medium / low), and a public source URL you can verify. There is no proprietary clustering — if an address is not listed, we do not infer it.

Methodology: we add entries when multiple independent public observations support the attribution (official announcements, explorer tags with citations, regulatory filings). Stale labels happen when entities rotate wallets — treat confidence as "how well sourced," not "forever true." Full rules in Methodology.

Contribute: email proposals via Contact with address, entity, source link, and reasoning. Pull requests on GitHub welcome for schema-valid JSON. We do not accept unsourced rumors or chain-analytics "consensus" without a primary citation.
