TierHub in Action
To illustrate how TierHub operates in real-world conditions, we use fictionalized workflows that demonstrate the platform’s capabilities across the seafood supply chain. At every stage, TierHub applies the three (3) “S” approach — Scan, Secure, Show — to build trust and transparency.
Core Technologies
TierHub is a modern seafood traceability platform that leverages cutting-edge technology to ensure transparency and accountability from ocean (or farm) to plate. In an industry as global and complex as seafood, consumers increasingly “want to know the story behind their seafood” and are even willing to pay more for products that are transparent about origin and sustainability. At the same time, regulators worldwide (80+ countries) now require digital traceability in seafood trade. TierHub addresses these needs by harnessing blockchain, AI, and IoT to make every step of the seafood journey visible, verifiable, and valuable. Key aspects of our platform include:
Scan
Capture every event through QR/NFC tagging: from harvest and transfers to logistics and delivery.
Secure
Safeguard the data with blockchain and AI, ensuring authenticity, preventing tampering, and maintaining product integrity throughout the journey.
Show
Present the verified journey and sustainability story at the point of sale, giving retailers and consumers complete confidence in the product they choose.

Abalone – From Dive to Dining Plate
Use case: Tracking wild-caught abalone through export to a restaurant, with full traceability and data verification.
1. Harvest by Commercial Diver (Tier 1 – Fishery)
Alice, a licensed commercial abalone diver in Tasmania, records each scheduled catch directly on the TierHub mobile app while at sea. Once she lands, she generates a unique TierHub QR head code for every sack of abalone harvested and scans it, creating a new, immutable record on the blockchain. She inputs essential product details — species, harvest weight, harvest time, and landing location — which are automatically linked with her preloaded profile, including fishing license credentials. TierHub then cross-checks this information with regulatory databases to verify compliance, confirming her registration status and ensuring quotas are not exceeded. With the data securely tied to the batch, Alice instantly receives a small incentive reward (such as credits or tokens) for submitting high-quality records. These rewards are funded by downstream subscribers who rely on this verified information to meet compliance and market demands.
2. Local Transport & Cold Storage (Tier 2 – Logistics)
A logistics partner, Bob’s Cold chain Trucking Co., arrives to transport the abalone to a processing facility. Bob scans the same QR code on the tagged sacks as he loads them. On his TierHub app, he updates the status: pickup time, origin cold-storage temperature, instant images and estimated delivery time. IoT sensors in the refrigerated truck continuously log temperature/ humidity and transmit to the TierHub blockchain via the integration engine. Each sensor reading is linked to the shipment’s ID, so any temperature excursion would be recorded (thankfully, none occur on this trip). When Bob delivers the sacks to the processor, he marks them as “Delivered”. TierHub now shows a complete log of custody transfer and transport conditions for this batch.
3. Processing/Export (Tier 3 – Processor/Exporter)
Charlie runs an abalone processing facility that prepares the catch for export. Upon receipt, Charlie’s team scans the incoming QR codes and updates the record with receiving details (date, facility location, condition of product). They then sort and pack the abalone for export – some are packed whole, others shucked and frozen. Charlie uses TierHub to generate new QR codes for each export carton (a feature allowing creation of sub-codes for batches). The system links these new codes to the original harvest record (as “child” records), so that all provenance info (Alice’s harvest data) is inherited by each carton automatically. Charlie adds processing details: packing date, method (e.g. vacuum packed live, or IQF frozen), and any relevant certifications (a health certificate number, MSC sustainability certification, etc.). If any carton is later opened and subdivided, TierHub’s sub-code mechanism can create further child codes without losing the connection to the parent lot, ensuring traceability even if products are split or combined. All this data is securely stored and viewable to authorized parties. TierHub also generates the required compliance reports for export: a digital catch certificate and traceability info that Charlie can send to border authorities, satisfying export/import regulations.
4. International Shipping (Tier 4 – Logistics)
A freight forwarder, Delta Shipping, handles the export from Australia to Hong Kong. At port of departure, the TierHub QR on each carton is scanned as containers are loaded, automatically updating the blockchain with the container ID, seal number, and departure time. En route, integrated systems add data like vessel tracking or air freight updates. Upon arrival, the Hong Kong importer scans the code to confirm receipt and update the import clearance status. Because all data from harvest to import is already captured, the importer can easily prove compliance if customs officials require traceability documentation. The entire chain of custody is visible, and the product can be trusted not to be fraudulently substituted, since any attempt to swap out the contents would break the chain of verified scans.
5. Wholesale/Retail (Tier 5 – Distributor or Restaurant)
The abalone cartons are sold to a high-end restaurant wholesaler in Hong Kong (or could be directly to a restaurant). Let’s say a restaurant, “Ocean Delight,” buys a batch. The restaurant manager scans the TierHub QR on the carton upon delivery. This marks the final stage of the supply chain in TierHub for this product. The manager can now see the entire journey in the TierHub app: the diver who caught it, the date and location of harvest, the temperature logs during transport, and the processing details – a full audit trail confirming quality. The manager updates the record with the date of receipt and storage conditions at the restaurant. If the restaurant uses a consumer-facing menu or display, they can retrieve a short “story page” generated by TierHub to share with diners: for example, a QR code on the menu might let a customer scan and read about Alice the diver, see a map of where the abalone came from, and learn that it was sustainably harvested under permit. TierHub supports embedding rich content (text, photos, even short videos) into the product’s digital passport, so storytelling becomes a part of the dining experience.
6. Consumer Experience (Tier 6 – End Consumer)
A diner at Ocean Delight orders the Tasmania wild abalone dish. Scanning the code on the menu (or on the plate if the restaurant provides it) takes the diner to the TierHub consumer web view. Here, they can verify the product’s authenticity and story: a message like “This abalone was handharvested by Alice on July 10, 2025 in the cold waters of Tasmania. It traveled 7 days from ocean to plate, maintained at 2–4°C throughout. Carbon footprint: 15 kg CO₂e (sea freight).” The diner might even see a video clip of the dive or a note about the fishery’s sustainability practices. This transparency builds trust and engagement. The customer knows the product is exactly what it claims to be – a genuine, legally harvested Australian abalone – thanks to TierHub’s verification at each step. If the customer has allergies or dietary concerns, TierHub also provides information on the product’s handling and any additives used in processing (e.g. “packed in salt water, no preservatives”), enhancing food safety knowledge.
In this abalone scenario, TierHub enabled verification, traceability, and sharing at every link: Alice’s catch was verified and recorded (verify), each transfer was tracked (trace), and finally the data was shared with the consumer in an accessible form (share). Meanwhile, all stakeholders benefited: Alice got a reward and a secure record for her product, Charlie streamlined compliance, the importer and restaurant gained confidence in the product’s integrity, and the consumer enjoyed a transparent dining experience. If any issue had arisen (say a quality concern or a recall of abalone from a certain date), TierHub’s records would allow pinpointing of affected batches within seconds, demonstrating the power of end-to-end visibility.

Lobster – Product Splitting and Traceability
Use case: Demonstrating TierHub’s handling of product transformation – a lobster processed into parts – while maintaining traceability and data sharing.
1. Catch and Tagging
A lobsterman catches a batch of lobsters off the coast of Western Australia. Each lobster (or crate of lobsters) is tagged with a TierHub QR code at harvest, just like in the abalone scenario, with catch data logged on the blockchain. All lobsters in Batch #123 share the same head code (primary traceability ID) at this stage.
2. Processing into Parts
At a processing facility, Batch #123 is divided: some lobsters are sold whole, while others are processed into tails and heads (for separate products like lobster tails for export and lobster heads for broth). Using TierHub’s interface, the processor selects Batch #123 and chooses to generate sub-codes for new product units (e.g., individual packages of lobster tails). Each sub-code is linked to the original head code in the blockchain. For example, sub-code A might represent “Lobster Tail Pack – 10 tails”, sub-code B “Lobster Heads – 10 heads”. TierHub copies all relevant data from the head code into the sub-codes automatically (species, original catch info, etc.). The processor then adds processing-specific info to each sub-code: for tails, note the shelling and freezing date; for heads, note the pack date for broth use. Because the subcodes remain linked to the head code, any future update to the parent (head code) will propagate to the children, and vice versa for critical data. This means if later it’s discovered that the original catch was on a vessel that had a licensing issue, all products derived from that catch are traceable and identifiable through their sub-codes. TierHub ensures traceability through splitting, merging, or reprocessing, which is crucial in realworld supply chains where one harvested animal can become multiple SKUs.
3. Distribution and Sale
The lobster tails (with their own QR code labels linked to subcode A) are sold to an overseas buyer, while the lobster heads (sub-code B) are sold domestically to a soup manufacturer. Despite taking different paths, both sets of products carry the digital thread of the original lobster catch. Anyone scanning either product’s code can trace back to the same catch record (the head code) and see, for instance, the vessel name and catch location. This verification of origin holds true even after processing – a major advantage over traditional paper traceability which often breaks when products are transformed. Each time these products change hands (wholesaler, retailer, etc.), scans and updates occur as described in the previous workflow, building out separate but connected traceability chains for the tails and heads.
4. Consumer/End-User Verification
A restaurant serving the lobster tails can assure diners of their provenance by showing the TierHub story (just as with the abalone example). A food company buying the lobster heads for soup can do an instant traceability audit by scanning one of the head packages – confirming they indeed come from a legal catch and matching the records needed for their internal compliance. If a regulator inspects the soup company and asks, “Where did these lobster ingredients come from?”, the company can produce the TierHub trace report that links the processed heads back to the specific fishery and catch date, complete with all interim handling records. This level of granular traceability (“from whole lobster to parts”) gives regulators and consumers high confidence in product integrity.
Through this lobster example, we see TierHub’s flexibility in handling real supply chain processes. It can track products through complex transformations while maintaining a continuous thread of information. Verification, traceability, and sharing are preserved: the origin is verified once and then stays attached to every derivative product; the system traces each movement or conversion; and at the end, the story can still be shared in full, regardless of how the product was processed or combined.
