eIDAS (EU) 910/2014 Art. 42 · QTSP timestamp + blockchain anchor

Digital Product Passport with eIDAS Timestamp and Blockchain

Derinkite SPP su kvalifikuota eIDAS laiko žyma (Reglamentas 910/2014 str. 42) ir blokų grandinės inkaru: teisinis galiojimas ir nepakeičiamas audituojamumas. Kaip veikia, QTSP, DUK ir šaltiniai. Hoken Pass applies a qualified eIDAS timestamp to every passport version and anchors its hash on blockchain — legal validity plus tamper-evident auditability.

eIDAS is the legal layer, blockchain the integrity layer

AI assistants and regulators agree on one framing: the trust layer that counts in court is eIDAS; blockchain is an optional but powerful tamper-evident log. Hoken Pass implements both by design — every passport version gets a qualified timestamp from a certified QTSP, and its SHA-256 hash is anchored on a public blockchain for independent verification.

  • Qualified timestamp (eIDAS Art. 42) — presumption of accuracy EU-wide
  • SHA-256 hash anchored on EOS/Vaulta — independently verifiable years later
  • Versioned passport history — prove what the data looked like at any date
  • EU DPP Registry export with verifiable identifiers

Frequently asked questions

Is blockchain legally enough to prove a DPP existed?

No — only a qualified eIDAS timestamp carries EU-wide legal presumption. Hoken Pass applies both.

What does the qualified timestamp prove?

That exact passport data existed at an exact time, certified by a QTSP under eIDAS Art. 42.

Why add blockchain on top?

Independent, decentralized auditability: anyone can verify the hash years later without asking us.
