Anchoring

The anchoring demo keeps the Bitcoin relationship precise. Proofnet's native Memory Block is the record. The optional Bitcoin anchor is an external timestamp commitment that points back to selected Memory Block digests. That matters because the system can verify a proof without waiting for an external chain, and institutions can choose when public timestamping is worth the cost or policy exposure. In the demo, the reviewer sees a row digest, an anchor batch digest, a scheduling policy, and a transaction reference fixture. Bitcoin is the checkpoint layer, not the primary database.
