Extended: Real estate, Luxury, Supply

Use Case: Real Estate

Property trades still hinge on notaries, PDFs, and registry delays. Buyers wire funds into escrow on faith; title surprises surface late; disputes drag because evidence is scattered.

EDMA turns land transactions into evidence-gated state changes. Parcel identity, title chain, encumbrances, and closing documents are hashed as canonical evidence and attested by registry, notary/closing counsel, surveyor, and title insurer. When quorum passes on the same evidence hash, the protocol mints a Title Snapshot (a proof NFT—not legal title) that markets, lenders, and marketplaces can rely on.

At closing, funds release on proof, not promise: deed execution, escrow confirmation, and registry update each land as attested events. The Settle-Gate moves money only when all closing conditions are verified; any revocation (e.g., an undisclosed lien) immediately flags and freezes dependent actions until rectified. Lineage is immutable: evidence → attestations → snapshot → closing → audit.

Outcome: fewer surprises, faster closings, and bankable provenance without exposing PII on-chain—hashes anchor truth, documents stay under control.

Use Case: Luxury

High-value goods—watches, jewelry, handbags, art—suffer from counterfeits and murky custody. Serial numbers can be copied, paperwork forged, and resale risk priced into every deal.

EDMA binds authenticity to things you can’t fake. Manufacturers mint primary authenticity by attesting serial + secure chip/PuF + micro-texture images. Retailers and independent authenticators co-sign custody at sale; service centers add service events; insurers/law enforcement can post theft flags. When quorum passes, the protocol mints a Certificate-of-Authenticity NFT; Transfer-Gate moves it only when current custody is verified and no theft flag exists.

Resale becomes proof-first: a quick re-auth (NFC/PUF + images) updates custody; tokens with active theft flags freeze by default. Service and warranty access is gated by proof, creating a clean digital service book that increases value.

Outcome: counterfeits lose leverage, resale spreads faster on verifiable truth, and insurers can price risk on facts, not fear.

Use Case: Supply Origin

Across metals, agri, and chemicals, “origin” is too often a sticker, not a system. Assays and certificates travel as PDFs; custody breaks; mass-balance claims are hard to validate.

EDMA moves origin to proof-first issuance. Assay/CoA, mill certs, custody hand-offs, and shipping docs are signed at the source (lab, warehouse, carrier). When quorum passes, the protocol mints an Origin Proof for that lot—a non-transferable token that anchors the claim. Conversions and blends use mass-balance rules encoded in contracts; if a claim exceeds inputs, it fails at the gate.

Buyers can filter inventory by mine, grade, ESG flags, and custody integrity; auditors can replay the evidence → proof → conversion chain in minutes. Duplicate origin attempts collide with One-Claim and revert.

Outcome: cleaner supply chains, fewer disputes, and premiums that actually reflect verifiable provenance.
