Polygonscan is a public blockchain explorer outside Boss Tag’s control — the proof does not depend on trusting us. On that page, the “To” address is the Boss Tag registry contract and the transaction’s input data contains the record hash shown above.

Run the proof yourself

Your browser rebuilds the record’s fingerprint from the fields on this page and checks it against the Polygon blockchain directly — nothing here depends on trusting Boss Tag.

Check this anchor without Boss Tag
