The EU Digital Product Passport registry opened Jul 19, 2026. AuthiChain issues ESPR-aligned passports that verify with no internet connection — the signature checks against the issuer's published key, not against our servers.
Works at factory floors, border crossings, and disconnected industrial sites.

ESPR Compliance
EU ESPR mandates that DPP data be accessible, verifiable, and tamper-evident. AuthiChain exceeds the spec — adding what no competitor can match.
GS1 Digital Link–compatible unique product identifier, queryable via the EU Central Registry from day one.
Ed25519 cryptographic signature on every data record — mathematically provable, no central trust required.
Every passport hashed and anchored on Polygon — any alteration is permanently detectable on-chain.
AuthiChain-exclusive: full cryptographic verification with zero internet. Works at mines, factories, and border crossings where competitors fail.
Only AuthiChain
Battery factories, mining operations and logistics hubs often have no signal. Where verification depends on reaching a vendor's server, a scan can complete while the verification behind it silently fails.
AuthiChain's Ed25519 verification runs entirely on-device, checking the signature against the issuer's published key. No server, no connectivity, no account. The reference verifier is Apache-2.0 — run it yourself and confirm it never opens a socket.
