Compare DSR side by side with the competitor you choose. Every rival point below is quoted from the competitor’s own published terms — this is a due-diligence asset, not a sales pitch.
A rival can match “residency at rest” on a foreign-backed cloud. The real moat is zero-egress by design, your-own-domain ownership and a funded continuity guarantee.
| Layer | DÜPAS | DSR |
|---|---|---|
| Residency (at rest) | Matchable — a rival can offer residency at rest | Türkiye-resident deployment (KVKK-aligned) |
| Zero-egress by design | Each scan/publish still pushes data back to central servers, the EU Registry or external engines | Verifies in-resolver — no third-party egress to verify a scan |
| Your-own-domain ownership | The passport lives on their domain | Published on your own domain (white-label) |
| Continuity | Pay-to-stay — passports go dark if you stop paying | Funded Continuity Guarantee + self-hostable |
DÜPAS’s own pricing requires an annual platform fee “to keep the passport published” and caps edits at three revisions per passport.2 The ESPR expects a Digital Product Passport to remain available for the product’s lifetime, with a back-up copy held so the record survives even if the operator fails (Regulation (EU) 2024/1781).3 A pay-to-stay-published model that can take passports dark, and a three-edit ceiling on a living supply-chain record, both cut against that. Our answer is the opposite: a funded Continuity Guarantee that keeps passports live for defined term-years on your own domain, and unlimited immutable versioning.
| DSR Protocol | DÜPAS (dupastr.com) | |
|---|---|---|
| What it actually is | ✓A living, item-level digital-twin + open conformity engine you own. | A DPP publishing SaaS: signed passport documents (UNTP / W3C VC) plus an accredited-validator network.1 |
| Versioning | ✓Unlimited, immutable, publicly verifiable version hash-chain. | A “3 Revision Right” — three edits per passport.2 |
| Staying published | ✓Funded Continuity Guarantee — passports stay live for defined term-years, on your own domain. | An annual Platform Usage Fee is required “to keep the passport published”.2 |
| Independent conformity sign-off | ✓Open multi-signature: plug in any accredited validator; the result is a UNTP DigitalConformityCredential verifiable offline, with no per-passport approval toll. | Validators operate inside their own accredited-validator network, with validator/approval fees bundled into the published packages — so independent sign-off runs through their ecosystem and its fee structure rather than an open standard.1,2 |
| Fee model | ✓Transparent and value-based; GS1 Digital Link and unlimited versioning included. | Stacked per-passport fees (application, pre-registration/registration, verification, operator service, digital hosting, platform) with QR labels & integrations extra.2 |
| Physical-item authenticity | ✓Optional chip-level NTAG 424 DNA (AES-CMAC / SUN) catches clones & transplants; plus 213/215 taps and GS1 Data Matrix. | Document-signature authenticity only — a copied QR still resolves to a genuine-looking passport. |
| Data residency & egress | ✓Deployable resident in Türkiye (KVKK); authentication runs in-resolver with no third-party egress to verify a scan; flat marginal cost at the edge. | Verification is performed through their platform and passports are published on their dupastr.com domain (not your own), under a per-passport, pay-to-stay model; Türkiye-resident data residency is not advertised. Residency at rest — wherever the database sits — is not the same as zero-egress verification by design, your-own-domain ownership, or a funded continuity guarantee.1 |
| Offline verification | ✓A passport verifies from the credential alone — no database, no network (customs / field). | Verification is performed through their platform.1 |
| Life-cycle assessment / carbon | ✓Your certified LCA / EPD is captured, cryptographically signed and independently validator-attested, and bound to the passport — we are the tamper-evident system of record, not an in-house calculator. | A carbon-footprint calculation is offered.1 |
| Whose domain the passport lives on | ✓White-label on your own domain. | Passports live on the dupastr.com panel domain.1 |
| Defensible IP | ✓Patent-pending resolver architecture; no blockchain, token or wallet. | None stated. |
