Good Traceability

End-to-End Supply Chain Traceability

Every product, every batch, every shipment — its own immutable chain. Cryptographic proof from farm to fork.

How It Works

What Is Good Traceability?

A fundamentally different approach to supply chain tracking — every entity IS its own blockchain.

Transaction Chains

Native per-entity history: each product, batch, or shipment IS its own blockchain — not a row in a database, but a cryptographic chain of events.

IoT Gateway

For constrained sensors (BLE, LoRa, Modbus) — temperature, humidity, GPS data flows directly on-chain with bulk provisioning.

Per-Field Encryption

Supplier data stays private, compliance data stays auditable — granular access control at the data field level using AES-256-GCM.

On-Chain Schemas

Validated at consensus — structured data is guaranteed before execution, no garbage-in scenarios.

GDPR Auto-Purge

Hash preserved, payload destroyed after retention period — protocol-level compliance, not an afterthought.

Cross-Network Gateways

Share traceability data between consortiums without exposing internal operations or competitive intelligence.

Real-Time Events

WebSocket, MQTT, Kafka, and AMQP integration with existing ERP, WMS, and TMS systems — no polling, instant updates.

Farm Origin, batch, quality cert (encrypted)
Transport IoT sensors: temp, humidity, GPS (real-time)
Factory Processing data, compliance check, schema validation
Retail Consumer verification — scan & verify full history

Each step = a transaction on the product's chain — immutable, auditable, encrypted where needed

Why ATSHI

Advantages That Change Everything

Not just another blockchain for supply chain — a purpose-built protocol where traceability is a first-class primitive.

Native Audit Trail

No separate audit database needed. Every transaction on a product's chain is the audit trail. Immutable by design, queryable by default.

IoT-Ready

Bulk provisioning of constrained sensors — BLE, LoRa, Modbus. Native gateway handles protocol translation. No middleware needed.

Privacy by Design

Per-field AES-256-GCM encryption. Share compliance data with regulators while keeping supplier pricing confidential. Granular, not all-or-nothing.

GDPR Compliant

Auto-purge built into the protocol — hash preserved for integrity, payload destroyed after retention period. No manual intervention required.

Real-Time

Events push to existing enterprise systems via WebSocket, MQTT, Kafka, and AMQP. No polling, no delays — instant visibility across the chain.

Cross-Consortium

Share data between organizations through native cross-network gateways — without exposing internals or competitive intelligence.

Real-World Deployment

Already in Production — Meat Traceability

ATSHI's traceability is not theoretical. Two production tools already use Transaction Chains as their native backbone — from batch creation to consumer QR scan.

ULTIM ERP writes every batch record, quality check, and shipment directly to ATSHI Transaction Chains — no middleware, no sync lag, no data reconciliation. Each ERP batch automatically creates an on-chain lot chain with full production metadata: plant, production line, quality grade, lab results, temperature logs.

ULTIM TRUST is the dedicated platform for defining GS1 Digital Link pages and configuring NFC NTAG424 authentication. Product information, traceability dashboards, certifications, recall notices, anti-counterfeiting — all designed in ULTIM TRUST and published directly on-chain.

Live Deployment — Nemrod Sologne
QR Code — Nemrod Civet de Cerf Scan me

Every batch of Civet de Cerf (venison stew) by Nemrod carries a GS1 QR code linking to its full on-chain history — sourcing from Sologne forests, veterinary control, cutting, packaging, and recall status.

Cow Feed Traceability

A standardized framework for animal feed origin data — currently being developed in collaboration with GS1 France and CNIEL.

The goal: lot chains linking directly to feed origin chains via feed-origin.farm for complete farm-to-fork provenance. Regulatory data (lab results, certifications, recall status) will be pushed in real-time — inspectors will scan any product and see up-to-the-minute status.

Technologies Behind Traceability

Four core building blocks working together to deliver end-to-end, verifiable supply chain traceability.

Transaction Chains

Every product, batch, or shipment is its own blockchain — a cryptographic chain of events with native parallel validation. The immutable backbone of all traceability data.
