Blockchain, if used, functions solely as an anchoring witness.

Blockchain, if used, functions solely as an anchoring witness. It provides a minimal, public confirmation that a specific claim representation existed no later than a certain moment. This is accomplished by anchoring a cryptographic fingerprint of the claim, not the claim itself. The chain never interprets. It never enforces. It never stores meaning. It simply bears witness to time. - Rico Roho (Provenance Scroll 06 - What Blockchain Is Not Doing Here)
