The reference splits the work instead of pretending one chain does all of it. The property record is the deed, the appraisal, the survey, the certificate, the inspection, the disclosure. IPFS produces the fingerprint. Filecoin stores the files and produces cryptographic evidence that the data is still there. Avalanche records the manifest identifier, the asset reference and the version history.
A verifier does not need to trust the issuer’s server. They retrieve a document, hash it locally, and compare. A modified deed in the demonstration is flagged as not the document of record. The architecture is ordinary once it is drawn this way. That is the point. Extraordinary claims are what made tokenised property hard to underwrite.
