Stop counterfeits. Own every resale.
A tamper-proof identity that proves a product is genuine and follows it through every owner and every resale — consumer-facing, global, no passport mandate required.
The problem
Counterfeiting costs Europe about €117 billion a year; clothing alone loses roughly €12 billion and 160,000 jobs. And in the booming second-hand luxury market, authenticity is the central friction — buyers and platforms spend fortunes proving what's real.
What notasserro does
It binds a soulbound identity to the item (it can't be cloned or sold separately) and pairs it with a transferable ownership token that moves on each sale — so the brand keeps a channel and every owner keeps verifiable provenance. Authentication is AI-assisted; the proof is a public-chain hash anyone can recompute, portable across any marketplace.
No EU mandate needed — notasserro sells on brand value and resale trust. The identity is owner-held, not locked in a brand database or a single resale platform, and AI does the authentication and data work to keep cost low.
A real-world journey — a leather bag, cradle to resale
Every step is a GPS-stamped QR / NFC scan — the record proves not just what happened but where. A hide from an Italian tannery that next scans in Shenzhen is an instant red flag; a plausible route (farm → tannery → atelier → boutique) builds a geographic chain-of-custody a counterfeit can't fake. At the right moments, an ownership transfer. Buyers never need a wallet — one is created behind a passkey or email. Delivered as your own whitelabel iOS & Android app, or inside your existing app.
The brand opportunity
The passport isn't just protection — it's a programmable relationship with every genuine owner, for the life of the product (drawn straight from the original notaserro vision).
Rewards & collectibles
Unique artwork, perks or experiences tied to verified ownership — turning a purchase into membership.
Hidden & unlockable assets
Content, warranties or benefits revealed only to authenticated owners — value a counterfeit can never carry.
Selective drops
Reward some, not all — first owners, the Nth resale, a region — gamified, surprise-and-delight loyalty.
Resale royalties
Earn a share on every authenticated resale — capturing secondary-market value for the first time.
A direct channel
Reach every current owner — recalls, care, upgrades, new drops — without a marketplace in the middle.
Whitelabel apps
Shipped as your own iOS & Android app, or embedded in your existing one — your brand, your experience.
Sub-edition NFT tree
Codes nest — item → case → box → pallet → container. Your catalogue & tracking attach to the item's NFT tree, and sub-editions (capsules, numbered runs, collaborations) mint along the way.
Proof of new
While the unlockable assets stay locked, the buyer has proof the item is new and first-hand — not just genuine, but never sold or opened. Uniqueness and newness in one.
Market intelligence
Aggregated, anonymised customer, retail, resale-market and location signals from genuine scans — real insight without holding personal data.
The luxury anti-counterfeit competition
Scored on verifiability and SME accessibility (5=best, 1=worst).
| Player | Type | Chain | Verif. | SME | Note |
|---|---|---|---|---|---|
| Aura Consortium | DPP / NFT (luxury club) | Permissioned (private payloads) | 2 | 1 | LVMH/Prada/Cartier — but closed; public can't recompute |
| Arianee | Tokenized passport | Public (EVM/Polygon) | 4 | 2 | Genuinely on-chain — but brand-minted, enterprise sales |
| VeChain ToolChain | Supply-chain anti-counterfeit | Public (VeChainThor) | 4 | 3 | Public + SME tier — but generalist, crypto-token friction |
| Certilogo (eBay) | AI authentication + digital ID | Centralized cloud | 1 | 2 | Strong AI — but vendor-DB, now eBay-captive |
| Entrupy | Physical AI authentication | None | 1 | 3 | Best physical auth — but no ledger, no ownership transfer |
| EON | Digital ID / DPP | Centralized | 2 | 2 | Powers RealReal/Vestiaire IDs — brand-DB, not public |
| Origyn | Biometric NFT auth | Public (ICP) | 3 | 2 | Auth + on-chain — but niche (watches), small footprint |
| notasserro | Verifiable identity + AI auth | Public chain | 5 | 5 | Cheap + public-verifiable + owner-held + AI authentication |
Where notasserro wins
- The luxury-native leaders are the least verifiable. Aura is a closed permissioned chain with private payloads; Certilogo/EON/the resale platforms are centralised "trust-us" databases. notasserro's "anyone recomputes the hash" is a genuine differentiator.
- Soulbound identity + transferable ownership is the unsolved combination. Aura/Arianee mint brand-owned passports; Entrupy/RealReal/Vestiaire produce non-portable proof. We bind identity to the owner yet let ownership transfer on resale.
- AI authentication fused with on-chain provenance. Entrupy nails "is it real now" with no ledger; Aura has a record with weak verification and no physical auth. Only Origyn does both — and it's niche. We cover the whole span, cheaply.
- Brand-neutral, not captive. Certilogo is eBay-owned; resale-platform proofs die outside their walls. notasserro's proof travels with the item and owner across any marketplace.
- Elements no incumbent combines — GPS-enforced scans (a geographic chain-of-custody), a nested sub-edition NFT tree, proof-of-new via still-locked assets, and anonymised market intelligence for the brand. Most competitors offer none of these.
