Supply Chain Standard

GS1 EPCIS 2.0 — Supply Chain Events, On-Chain

Every supply chain event — shipping, receiving, transforming, inspecting — captured in the four EPCIS dimensions (What, Where, When, Why) and written natively to ATSHI Transaction Chains. The global standard for supply chain visibility, made immutable.

What Is EPCIS 2.0?

EPCIS (Electronic Product Code Information Services) is the GS1 standard for capturing and sharing supply chain events. It defines a universal language for answering the fundamental questions about any product in any supply chain: what happened, where, when, and why.

Version 2.0 uses JSON-LD natively — which maps directly to ATSHI's structured data schemas validated at consensus. No translation layer, no middleware, no data transformation. The standard's data model and the blockchain's data model speak the same language.

Core Business Vocabulary (CBV) 2.0 provides standardized business steps: commissioning, shipping, receiving, transforming, inspecting, destroying. Every supply chain actor uses the same vocabulary, eliminating ambiguity across organizations, industries, and borders.

On ATSHI Network, every EPCIS event becomes a transaction on the product's chain — immutable, timestamped, cryptographically signed. The event cannot be altered after the fact. The signer cannot deny having created it. The timestamp is consensus-validated, not self-reported.

Combined with GS1 Digital Link: one QR code reveals the full event history from farm to shelf. Scan a product, see every event that ever touched it — every handoff, every inspection, every transformation — verified on-chain.

The Four Dimensions

Every EPCIS event answers four fundamental questions. On ATSHI, every answer is immutable.

📦

What

Which products or trade items are involved. GTIN, batch/lot number, serial number. Each identifier is linked to the product's on-chain identity — a Transaction Chain that accumulates every event across the product's entire lifecycle.

Product Identity
📍

Where

Location of the event. GLN (Global Location Number), geo-coordinates, facility identifier. On-chain proof of location — the event is cryptographically bound to the declared location at the moment of capture.

Location Proof
🕒

When

Precise timestamp of the event. Immutable, consensus-validated. No backdating, no tampering. The network agrees on the time — not the reporter. A shipping event at 14:32 UTC stays at 14:32 UTC forever.

Consensus Timestamp
🎯

Why

Business context. Business step (shipping, receiving, transforming) and disposition (in_transit, in_progress, recalled, active). CBV 2.0 standardized vocabulary ensures every actor across the supply chain speaks the same language.

Business Context

Six Event Types

EPCIS 2.0 defines six event types that cover every supply chain interaction. Each one becomes an on-chain transaction.

📋

ObjectEvent

An event involving one or more physical objects. The most common event type — observation, shipping, receiving. A batch of olive oil leaves the warehouse, a pallet arrives at port, an inspector checks a shipment.

Most Common
📥

AggregationEvent

Packing objects into a container, loading a pallet, filling a truck. Parent-child relationships recorded on-chain. Open a case and the blockchain knows exactly which items are inside.

Parent-Child
📄

TransactionEvent

Linking physical objects to business transactions — purchase orders, invoices, delivery notes. The physical flow and the business flow are bound together on the same chain.

Business Binding

TransformationEvent

Raw materials in, finished product out. Cheese production, wine blending, pharmaceutical manufacturing. Input lots and output lots linked with full ingredient traceability.

Input → Output
🔗

AssociationEvent

Associating a sensor, certificate, or device with a product. Temperature logger attached to a shipment. Lab certificate linked to a batch. Digital twin bound to a physical asset.

Device & Cert Binding
🔧

Custom Extensions

EPCIS 2.0 allows vendor extensions. ATSHI adds on-chain proof, per-field encryption, and real-time event streaming. Standard-compliant with blockchain-native capabilities layered on top.

Why On-Chain EPCIS?

Traditional EPCIS repositories store events in databases. ATSHI writes them to the blockchain. The difference is fundamental.

🔒

Immutable Event History

Every EPCIS event is a blockchain transaction. Cannot be altered after the fact. Regulators get tamper-proof supply chain evidence — not exportable reports that could have been modified.

Tamper-Proof
🔐

Per-Field Encryption

Public traceability data alongside encrypted business-sensitive fields (pricing, supplier identity, internal quality scores) in the same event. AES-256-GCM at the field level — not all-or-nothing.

AES-256-GCM

Real-Time Notifications

Events trigger instant notifications via WebSocket, MQTT, Kafka, AMQP. Partners, regulators, and consumers see updates in real-time — not on the next polling cycle.

Instant
🏛

Regulatory Compliance

Meets EU FMD (pharma serialization), EU food safety regulations, and US FSMA 204. The audit trail regulators demand — built in, not bolted on.

EU & US Ready
👥

Cross-Organization Sharing

Partners read events scoped to their role. A retailer sees receiving events, a regulator sees inspection events, a consumer sees the simplified journey. Same chain, different views.

Role-Scoped
📐

JSON-LD Native

EPCIS 2.0 uses JSON-LD. ATSHI's data layer validates JSON-LD schemas at consensus. No translation layer, no middleware, no data loss. The standard and the chain speak the same language.

Zero Translation
