Barcodes are disappearing. By 2027, GS1 is replacing them with QR codes powered by Digital Link — a single scan that connects consumers to product information, traceability, certifications, and recall notices. ATSHI Network hosts a fully decentralized GS1 Digital Link resolver where all product data lives on-chain. No centralized database, no single point of failure, no trust delegation.
If the resolver goes down, every QR scan fails. Millions of products become unreachable. One outage, one vendor, one catastrophic dependency.
The resolver operator can silently alter product data or redirect destinations. You trust a third party with your product identity — and hope they never abuse it.
No immutable, publicly verifiable history of changes. Who changed what, and when? You'll never know for sure. Logs are controlled by the operator.
The product owner depends on a third party to store and serve their data. Switch providers? Start from scratch. Your product identity is rented, not owned.
Consumer or partner scans the QR code. The URI is parsed — GTIN, lot number, and optional serial extracted per GS1 Digital Link URI Syntax v1.2.
The resolver computes a deterministic address from the GS1 path. Product chain (GTIN) and lot chain (GTIN+Lot) are separate chains with a parent-child relationship.
Product data, lot data, linksets, and routing rules are fetched directly from the blockchain. Lot data merges with and overrides product-level data.
Context-aware routing: consumer gets a product page, B2B gets traceability data, regulator gets compliance documents. Language, country, and time-windowed rules supported.
Three response modes: RFC 9264 linkset JSON, 303 redirect to the best match, or server-side rendered HTML via ATSHI Web Handlebars templates.
Every product and every lot gets its own chain — deterministic, verifiable, and cryptographically owned.
Parent-child hierarchy — lot chains inherit from and override product-level data
Resolver replicated across the network. Multiple nodes serve simultaneously. One goes down? The others don't notice. Your products stay reachable.
Every product data change is an on-chain transaction. Tamper-proof history for regulators, partners, and consumers. Verifiable by anyone, alterable by no one.
Only the product owner's private key can update product data. No admin panel, no API key — math enforces it. Your product identity belongs to you.
Consumer sees product info, B2B partner sees traceability, regulator sees compliance docs. All from the same QR code. Language, country, and time-windowed rules.
GS1 Resolver Community Standard v1.2.0, RFC 9264 Linkset, GS1 Digital Link URI Syntax v1.2. Not proprietary — built on open standards.
Handlebars templates hosted on-chain via ATSHI Web. Product pages rendered server-side with full i18n support. No external CMS needed.
| Capability | Centralized Resolver | ATSHI Digital Link Resolver |
|---|---|---|
| Infrastructure | Single server / CDN | Distributed across network nodes |
| Data ownership | Operator stores your data | Product owner's chain — cryptographic control |
| Audit trail | Operator-managed logs (deletable) | Immutable on-chain transaction history |
| Failure mode | Server down = all scans fail | Network-wide redundancy, self-healing |
| Data modification | Operator can alter silently | Only private key holder can write |
| Routing | Static redirects | Context-aware (consumer, B2B, regulatory, geo, language) |
| Response formats | 302 redirect only | RFC 9264 linkset JSON, 303 redirect, or rendered HTML |
| Standards compliance | Varies by provider | GS1 v1.2.0, RFC 9264, Digital Link URI Syntax v1.2 |
| Lot-level granularity | Often GTIN-only | Two-level hierarchy (GTIN → Lot), serial in Phase 2 |
| Cache invalidation | Manual / TTL-based | Automatic via on-chain event subscription |
Farm-to-fork history in one QR scan. Dairy, meat, wine — every batch with its lot-specific data, lab results, certifications. Meets EU food safety and US FSMA 204.
EU FMD serialization-ready. Each unit gets a serial chain with tamper-proof production data. Recall notices propagate instantly across the resolver network.
NFC NTAG424 + GS1 Digital Link. Cryptographic proof of authenticity from the blockchain. Cannot be cloned, cannot be faked. Every item verifiable.
Partners access traceability dashboards via the same QR code. Context-aware routing serves B2B data to authenticated partners, consumer data to everyone else.
Decentralized, immutable, standards-compliant. One QR code, full product history, zero servers.
